2. SAFETY INSTRUCTIONS
Any serious incident that occurs in relation to this medical device should be reported to STERIS and the competent authority of the member state in
which the user and/or patient is established.
Warning: The modification of the medical device without manufacturer authorisation is prohibited.
Pinch points
! During patient positioning, moving dierent sections of the tabletop and using extensions
and accessories can cause pinch points to appear which can injure the patient or the
surgical team. Users must therefore be aware of the risks and pay particular attention to
the following zones :
Precaution during the movements
! Before any movement activation, be sure that there is no risk of contact or collision with
an object, an equipment or a person.
Floor lock
! Even if the table is not locked to the floor, certain tabletop movements are still possible.
Lock the table to the floor before positioning the patient and starting the surgical
procedure.
! Do not try to move the locked table.
! Once the table is locked to the floor, ensure that it is stable. Move it if necessary to find
a flatter floor surface.
Moving the table with a patient on it
! When moving the table with a patient on it, the following conditions are required:
-The tabletop must be centered over the column or above the long part of the base.
-The patient should be in normal position.
! Never try to unlock the table and move it with the patient, if the table is not in the
transport position. The table may tip.
! If moving the table with a patient be careful to hold the patient in place.
! Before going anywhere, ensure that there are no obstacles along the way you wish to
take. The table is not intended to cross thresholds, to ascend or to descend steps.
Always move the table very carefully.
! Do not keep objects on the base as they may fall during motorised manoeuvres and cause
jamming when lowering the column’s sliding covers.
! Consider a safe zone where you’ll not put anything on it.
Safe zone
Switching the table on
! Every time you turn the table on, check that the pre-selected patient orientation
corresponds to what you want to do. When you switch o the table, the patient
orientation pre-selection is memorised.
! If the hand control and the optional pedal are used at the same time, the hand control
overrides the pedal.
Switching the table off
! The STOP buttons on the main hand control and on the override system allow you to
stop all table movement. They deactivate the optional pedal and other external control
mechanisms.
! Note that the battery of the optionnal wireless remote control do not charge anymore when
the table is switched o by the STOP function, even if the table is connected to the Mains.
! The table stops automatically at the end of a preprogrammed cycle (3’ by default with
standard remote control in wired mode. 240’ in wireless mode with optional remote
control).
Handling the surgical table
! Avoid handling the surgical table roughly during the operation. Do not exert excessive
lateral loads on it, do not pull or push the surgical table with the accessories or with the
rails.
! Avoid handling the remote control and the override system roughly. Do not press the
keypad with too much force or using unsuitable objects. Avoid shock on the control
means of the table.
! Avoid handling the cables roughly when connecting or disconnecting the remote control,
the foot pedal or the power cord set.
! Do not sit on one of the two ends of the table, especially when the tabletop is not
centered, as this can cause the table to tilt.
! Do not stand on the base of the surgical table because it can damage the covers.
! When a power cord is connected to the surgical table, and therefore is lying on the floor,
pay attention to this power cord when moving around the surgical table and remove the
cable before moving the table.
Weight capacity
! Do not exceed a patient+accessory weight of 270 kg for the standard described
positions and respect the indications and warnings signalled.
! The use of certain extensions may decrease this patient+accessories weight. When
extensions are installed on the KERNA™ General Surgical Table, you should also
consult the user manuals of these extensions to know the possible weight restrictions
related to the use of these extensions.
! In positions where the tabletop will be significantly slide away from the column, ensure
that there is sucient stability for the type of surgical procedure requirements.
! For all other uses, please contact our network for advice. If you are working intensively
on the patient’s chest, we recommend that you bring the tabletop back to a centred
position on the column.
Positioning the patient
! The positioning of the patient remains under the responsibility of healthcare professional.
It is the responsibility of the operator to ensure that the movements made are under his
control and do not generate any instability or danger to the patient during the surgery
performed.
! Ensure the stability of the patient and the table when making combined position.
! Secure the patient properly (ex. using straps), especially when the table has a strongt tilt inclination.
! Long surgical procedures can cause compression points on patients and have post
operative consequences. Monitor patient during surgical procedures and use gel
cushions for extented procedures.

[4]
Autonomy
! Two 12V sealed gelified-lead battery is integrated into the base and mean that
KERNA™ General Surgical Table is autonomous. Before using the table, check that the
battery is suciently charged.
Connections
! The sockets are equipped with locks: do not pull on the hand control or pedal cables to
disconnect them.
! Never try to connect a device not supplied by STERIS to the surgical table.
! Always use the power cord provided by STERIS.
! The operator should never touch the patient when the operator is plugging or
unplugging the remote control or the the pedal, or when the operator is handling the
connectors of these devices.
Potential equalisation conductor
! Connect together potential equalisation conductors to overcome the problem of diering
potentials across networks.
! Originally intended for cardiac areas, it protects the patient from electric shock during
procedures where even small potentials may cause harm.
! When a potential equalisation conductor is connected, the table MUST NOT be used
with a defibrillator
! When the use of the potential equalisation conductor allows to create an electromedical
system, then this system must meet the requirements of IEC 60601-1.
Antistatic link
! If antistatic connection is necessary, we recommend that you only use the pads that
have been specially developed for this product. Put the patient in direct contact with
them and use the table on an antistatic floor, or connect it to an equipotential cable
using the socket designed for this.
Electrical safety
Warning: To prevent any risk of electric shock, the
appliance should only be connected to an earthed
power supply system.
!
! The KERNA™ General Surgical Table must always be positioned so that the power cord
can be disconnected easily when connected to the table.
! The power cord with its main electrical plug is thus the device used to isolate the table
KERNA™ from the main electrical supply.
! It is preferable to use the battery instead of the main electrical supply if you have doubts
about the protective ground in the operating room.
! The use of high-frequency surgical equipment, cardiac defibrillators, and cardiac
defibrillator monitors in association with the KERNA™ General Surgical Table creates a
risk of burns, explosion, or electrical shock. The user must be aware of this.
! In case of any damage to the power supply or Mains cable or plug or IEC socket, do not
connect the equipment and immediatly contact STERIS technicians.
Accessories
! If accessories made by other manufacturers are used, it is the user’s responsibility to
check that they are compatible with KERNA™ General Surgical Table and that they do
not endanger the patient and the surgical team.
! Before connecting accessories to the surgical table, check the general state of them to
ensure that they are not degraded and that the connection system is not damaged.
! The end user shall especially ensure that the intended use and the conditions of use
(including the safe working load) of these accessories made by other manufacturers are
compatible with the claims of KERNA™ General Surgical Tables.
! Ensure that the extensions and accessories are correctly clamped to the surgical table
before each surgical procedure.
Electromagnetic compatibility
! If the table is used close to other electrical equipment, ensure that these comply with the
current regulations regarding electromagnetic compatibility.
! If high frequency equipment (such as a defibrillator) is being used, make sure that the
manufacturer’s instructions are rigorously followed.
Emergency mode
! When the override control panel is being used, the other control systems including the
main hand control are automatically switched off.
! Lock / Ensure the table to the floor before starting any movements with a patient.
Cleaning
! Ensure that the socket protection correctly protects the plugs so that fluids do not get in.
After cleaning procedures, ensure no residual water remains near the plug.
! Before cleaning the table, ensure that it is switched o. Put on the socket protection.
! Do not immerse the hand control and do not spray cleaning products directly onto the
sockets.
! Hypochlorite solutions can damage metal parts. After disinfection, ensure it is rinsed o
thoroughly with water and dry the surface. Prolonged exposure to hypochlorite solutions
may degrade mattress material. Avoid hypochlorite solutions and other liquids coming
into contact with any internal parts of the table.
Hand control storage
! We recommend hanging the hand control on a table rail when the hand control is not in
use, to prevent any accidental pressing of the buttons. Handle the hand control and the
associated cable with care.

Characteristics
The KERNA™ General Surgical Table is a multi-sectional, autonomous, electro-
hydraulic surgical table.
The table will be presented in the rest of the manual equipped with a double
articulation head section and split leg sections for convenience.
KERNA™ General Surgical Table offers exceptional radiological access without
the need for additional extensions or for the patient to be reversed.
The KERNA™ General Surgical Table is suitable for most surgical procedures
and has been designed to support patients+accessories weighing up to 300 kg.*
A standard remote control or an optional remote control can be both used with
the table.
Movements may also be carried out by using the optional pedal.
If using motorized legs (LEG10M or LEG01M), the optional remote control is
necessary.
* Veuillez vous référer au chapitre 8 Capacités de poids
An original integrated power system enables the table to run on battery or on
Mains depending on user preference.
The tabletop movements are motorised, with the exception of the headrest and
manual split leg sections.
KERNA™ General Surgical Table’s intelligent electronic E-Serve™ system
allows users to operate the table remotely, and also allows for diagnostic
and maintenance via computer performed by authorised and trained STERIS
personnel (errors, history).
The integrated ALS™ linear and angular position sensors avoid collisions
between the motorised sections and the table.
Finally, an integrated backup system (emergency panel) covering as many
breakdown issues as possible, allows the user to continue the “in process”
procedure and to remove the table from the room.

5. SETTING UP THE TABLE
Clic!
To remove the head section, you only need to press the 2 buttons located on each
side of the tabletop once because of the push spring integrated into the Hi-lock™
system.
Pull the pins out completely while supporting the weight of the head section.
Please refer to the head section user manual.
5.1 Attaching/removing snapLINX™ mattresses
Warning! INFECTION HAZARD
Ensure mattresses are free from cuts, splits and abrasions. Replace worn mattresses for new ones as soon as possible to eliminate possible biological
hazards.
Y
To fix the mattress to the section:
1. Ensure that the tabletop is clean and dry before installation.
2. Offer up the mattress to the section so that the snapLINX™ pins are lined up with attachments in the underside of the mattress.
3. Gently ease one mating attachment at a time onto and over the respective snapLINX™ pin.
4. The mattress should lie flat on the section when this has been achieved without evidence that the snapLINX™ pins are holding the mattress
off the section.
5. Check the fixation, trying to move the mattress laterally.
5.2 Mounting / demounting extensions
The KERNA™ General Surgical Table is equipped with Hi-lock™ locking system using side buttons. It is compact, easy to use and secure.
With Hi-lock™, an extension is automatically locked-in when it is inserted, and just by using the side buttons it is then removed.
Depending on the type of extension and the required safety level, it may be necessary to press the button twice in order to remove the extension. Do not force the
extension if it does not release after pressing the button once.
For convenience, it is preferable to install and remove the extensions when the table is in a horizontal position.
Example – installing / removing a head section
Insert simultaneously the two pins of the head section into the two holes in the back or seat section of the table. The head section should attach easily; you will
hear a click on each side when the automatic locking happens. Check that it is locked correctly by trying to pull the head section out.
Depending on your choice you will have either mattresses with Velcro attachment or mattresses with snapLINX™ attachments.
General Surgical Table - KERNA™
[11]
Click!
Example – installing / removing the split leg sections
For each leg section, insert the pins into the corresponding holes (left or right) in the back or seat section of the table. When the pin is 3/4 inserted, make sure
that the anti-rotation pin is aligned with the casing on the table upright. Do not force it: the leg section should attach easily. You will hear a click on each side
when it becomes locked automatically. Check that it is locked correctly by attempting to pull out the leg section.
The leg sections are equipped with a double security system: to remove them, the side button on the relevant leg section must first be pressed in order to release
the anti-rotation pin.
There are then two ways to remove the leg section completely. The user must be ready to support the weight of the leg section being removed:
-Press the side button on the relevant leg section a second time and completely extract the pin while supporting the weight;(see steps below)
-Rotate the leg section while continuing to extract the pin and supporting the weight.
5.3 Inserting and removing the battery fuse:
For reasons of safety during transport, the battery fuse is packed separately.
1. Insert the fuse into the fuse holders provided separately.
2. Insert all of this into the fuse holders.
3. Push and turn using a screwdriver in order to lock the fuse holder.
4. Check by switching on the table with the main hand control without using the
Mains. The three colored LED (green, orange and red) will flash for a few seconds.
If the table is not used for a long period of time (>1 month), remove the fuse in order
to limit battery discharge and maintain battery functionality

6.1 OPERATING THE KERNA™ MAIN HAND CONTROL (standard version)
The main hand control includes:
1. A 5 m spiral cord with a connector at each end making it easy to replace.
2. A plastic housing equipped with a hook so that it can be attached to the table’s side rails.
3. A keyboard allowing direct access to the function of the table
To level the table:
The blue LED will permanently light up when the table is in horizontal position.
The return-to-level button enables the tabletop to be returned to a horizontal position.
During the return to level tabletop movements, even if it is automatically realised, always ensure patient safety.
1. To return the tabletop to level: (the level LED is switched off if the tabletop is not horizontal)
2. Press the 0 button; the blue LED will flash during the tabletop movements.
3. The blue LED will be permanently on when the tabletop is horizontal.
Switching on the table
Pressing any button (except the STOP button) turns the table on but does not start any movements. A welcome screen is then displayed for a few seconds. You
can then press the button for the required movement.
Switching o the table
When the STOP button is pressed, the table immediately stops.
The Auto-off function turns off the table after 3 minutes if it is no longer in use in order to avoid any unintentional movement and to conserve battery life.
Locking / unlocking to floor
The mobile base of the KERNA™ General Surgical Table allows it to be moved around the operating theatre so that it can be relocated or so that the floor can be cleaned.
Locking / unlocking to the floor is controled automatically from the hand control.
During locking / unlocking (which takes a few seconds) all of the buttons, except the STOP button, are disabled.
The Locking/unlocking button has to be pressed more than 1 second.
When the blue LED blinks the table is on its castors. When the blue LED is fixed the table is locked.
All movements are authorized even when the table is on its castors.
Before starting any surgical procedure, check that the table is locked to the floor and stable. The floor locking pads can compensate by up to 4mm if the floor is
not quite horizontal: if necessary, move the table to find a more stable location.

7. OVERRIDE SYSTEM
If the table does not work correctly with the battery or the Mains, an override keypad located on the
column shall be used to replace the main hand control.
When the override system is in use:
-the main hand control is automatically switched off;
-the patient orientation described by the buttons is always in normal orientation;
-the sensors, and therefore the ALS™ system, are on standby.
You should therefore pay particular attention to the patient and look out for potential table section
conflicts, and contact the STERIS service.
Operation with the override keypad (powered mode)
-Simultaneously press the desired movement and the Powered Override Validation button. .
-The movement starts with a beep indicating that attention is required.
NB:
-Placing the table on the castors requires also the use of the button .
To unlock the table, keep pressing the buttons long enough until floor lock cylinders are
fully retracted.
To lock the table , keep pressing the buttons long enough until the floor lock cylinders
