A WORD FROM STERIS CORPORATION

This manual contains important information on proper use and care

of this surgical lighting system. All operators and department heads

are urged to carefully review and become familiar with the warnings,

cautions, and instructions contained herein. Your new surgical

lighting fixture features an advanced, state-of-the-art design, with

cool, shadow-reduced light, and ease of maneuverability. It

produces light of a quality necessary for the most demanding and

complex of surgical procedures.

A thorough preventive maintenance program is essential for safe

and proper operation of your surgical light. You are encouraged to

contact STERIS concerning our annual maintenance agreement.

Under the terms of this agreement, preventive maintenance,

adjustments, and replacement of worn parts are done on a

scheduled basis to verify lighting fixture performance according to

its specifications and to help avoid untimely or costly downtime.

STERIS maintains a nationwide staff of well-equipped, factory-

trained technicians to provide this service, as well as expert repair

services. Contact STERIS for details. STERIS is also able to provide

customer training; contact STERIS customer service for more

information.

Any ancillary equipment (e.g., monitors, video recorders, etc.) that is

to be used with this lighting system must comply with all applicable

medical equipment standards.

Indications for Use The Harmony® LC Surgical Lighting System is a variable pattern,

variable intensity surgical lighting fixture designed to provide visible

illumination of the surgical field or the patient for the operating room

staff.

Advisory The following is an important message from STERIS about the

advantages and limitations associated with the use of high

intensity surgical lighting systems.

Because of the variety of surgical procedures performed and the

wide range of individual preferences of surgical staffs, it is desirable

that a surgical lighting system be capable of selective control across

a wide range of illumination intensities. The Illuminating Engineering

Society (IES) stresses that in addition to providing control of

intensity, surgical lighting systems should provide shadow control,

correct color rendition, and a suitable depth of field to provide sharp,

consistent lighting into deep body cavities. As illumination levels

increase, however, radiant heat also increases. Therefore, the IES

cautions that for most operations, radiant heat should be kept to a

minimum. The user of surgical lights should utilize the lowest

possible illumination level suitable for the procedure, especially in

certain neurological or intestinal procedures on delicate, thin, dry, or

abnormal tissue. Furthermore, for the protection of surgically

exposed tissues and for the comfort and efficiency of the surgeon

and assistants, radiant energy can be effectively controlled by

limiting the time of exposure at higher illumination levels. Extra care

must be taken when the light fields from multiple lightheads are

overlapped on the surgical site, since this condition creates a risk of

too much heat.

An international standard for the safety of surgical lights established

by the IEC sets minimum and maximum levels of illumination and

maximum levels of radiant heat that can be emitted from a single

surgical luminaire. The LC Surgical Lighting has been designed to

comply with this international standard and to provide a wide range

of illumination levels while minimizing the potentially damaging

infrared heat in the surgical field.

The illumination level of the Harmony LC Surgical Lights can be

adjusted through several intensity settings via conveniently located

controls on either the wall-mounted control center or the lighthead

handle. The illumination level also decreases as the pattern size

increases. Maximum illuminance can exceed 12,000 fc for the

smallest pattern size of the Harmony LC lighthead and can be

adjusted by intensity control or pattern size control throughout the

entire range specified by the IEC.

3.1 Intensity Controls The wall-mounted Harmony® LC Wall Control allows the user to

adjust the lighthead intensity level by pressing membrane switches

(or buttons). Each lighthead is capable of seven light intensity levels,

1 being the lowest intensity and 7 being the highest. An identifying

number on the control display corresponds to the same number on

the lighthead suspension arm. Additionally, each lighthead has its

own onboard intensity control located above the lighthandle

adjacent to the lens. These controls are usually referred to as the

surgeon's control buttons or as the surgeon's control (see Figure 3-

2).

3.1.1 Activate the Harmony LC

System

Refer to Figure 3-1. Press ON/OFF touch pad. This turns the system

on in active mode and restores system lightheads to same intensity

levels as before system was turned OFF.

When the system is ON, ON/OFF LED glows green and it does not

blink (i.e., is steady). This state is referred to as ACTIVE mode. When

the system ON/OFF switch is pressed while system is ACTIVE,

system switches to STANDBY mode. In STANDBY mode all lights

turn off, the optional camera module (if present) turns off, and ON/

OFF led glows green and blinks.

• Intensity levels for one to three lightheads can be controlled

remotely from one wall control.

3.2 Harmony LC

Lightheads Lamp

Failure Indications

LEDs on the wall control indicate lamp status. If the wall control lamp

status LED is lit, it indicates the primary lamp or the secondary lamp

(or perhaps both), have failed. A failed lamp should always be

changed at the earliest opportunity.

Another lamp status LED is located on each Harmony LC lighthead

(see Figure 3-3). When flashing, the lighthead LED indicates one or

both lighthead lamps should be replaced.

• Check the lamp status LED each time the surgical light is used.

• A secondary lamp inside Harmony LC lightheads automatically

turns on when the primary lamp fails.

• If either lamp status LED is blinking, replace the failed lamp(s).

(See SECTION 6.7, LAMP REPLACEMENT, PAGE 6-5.) After lamp is

replaced, primary lamp lights, and LED indicators on lighthead

and wall control stop blinking.

3.5 Lighthandle and

Lighthandle Cover

Lighthandles are used to position Harmony LC lightheads, allow

access to intensity control on each lighthead, and to adjust lighthead

pattern size. To avoid accidental contact with the non-sterile

surgeon's control buttons, the lighthandle should always be used

with a disposable, sterile lighthandle cover (available separately

from STERIS).

• If the lighthandle adapter is not already in place, align the tab on

the adapter with the channel in the mounting ring and thread the

adapter in until fully engaged. (See Figure 3-6.)

NOTE: The Harmony LC lighthead does not have a separate

adapter. Adapter is permanently integrated into lighthandle

assembly.

Prior to starting a procedure, ensure that the lighthandle is in place.

Install the lighthandle by threading onto the adapter and firmly

tightening (see Figure 3-6).

• Remove the sterile lighthandle cover from its packaging and

install onto the lighthandle (see Figure 3-6).

• To ensure the lighthandle cover remains in place during the

procedure, the groove in the cover must be fully engaged with

the groove in the lighthandle.

• The lighthandle can be removed for cleaning or sterilization by

unscrewing it from the handle adapter. The lighthandle can be

sterilized using standard hospital cycles. Do not use the

lighthead during a sterile procedure unless a disposable cover is

installed on the lighthandle.

3.5.1 Installing and Using

Lighthandle and Lighthandle

Cover

The metal sterilizable handle is used to position the Harmony LC

lighthead and to adjust the light pattern size. The sterilizable handle

may be used in place of a disposable sterile lighthandle cover.

The plastic lighthandle should be removed prior to installing the

metal sterilizable handle. To do so, simply unscrew it from the

threaded handle adapter.

3.5.2 Metal Sterilizable Handle Prior to starting a procedure, install a clean, sterilized metal handle

by screwing it onto the threaded handle adapter. Ensure handle is

firmly tightened prior to use. The gap between the flange on the

metal sterilizable handle and the surgeon's control buttons prevent

accidental contact with the non-sterile surface of the buttons.

The metal sterilizable handle can be removed for sterilization by

unscrewing it from the adapter.

The metal sterilizable handle can be sterilized using standard

hospital steam cycles intended for lumens. Always sterilize handle

between surgical procedures.

WARNING – POSSIBLE PATIENT

INJURY HAZARD: Failure to

engage the lighthandle cover

completely may result in cover

falling from lighthead during the

procedure.

WARNING – STERILITY

ASSURANCE HAZARD: Do not

use the surgeon’s control buttons

unless a disposable sterile cover

is installed. If the sterilizable

lighthandle (metal) is used

without a disposable cover, the

surgeon’s control buttons are not

protected by a sterile covering.
