INTRODUCTION
Thank you for purchasing the TOPCON AIT Table.
This User’s Manual covers models AIT-250W, AIT-350W, AIT-650, AIT-W1, and AIT-W2.
The primary difference between these models is the shape of the top and floorplate.
The AIT Table is a state-of-the-art table that provides the ultimate Ophthalmic and Optometric instrument
delivery. The unit is intended to hold the diagnostic instruments and to facilitate the proper adjustments for
the operator and the patient.
Please carefully read this user’s manual to get the best system performance, and place the manual in a
convenient location for future reference.
PRECAUTIONS
1. Installation. Never position the unit where it will be exposed to moisture, direct sunlight, dust, salty air,
chemical storage areas, excessive temperature or humidity. Install the unit in a stable place, free of
uneven floors, vibration and shock.
2. Prior to Operation. Always check that all the cords are properly connected.
3. Operation. Take the proper steps to stop the unit (leaving the patient in a safe condition) if anything is
found wrong with the unit.
4. After Operation. Never hold and pull the connecting cord for disconnecting plugs. Excessive force may
be applied and cause damage to the inside connections. If the unit has not been used for a long period of
time, check the operation and safety features before using it again.
SAFETY CONCERNS
The AIT Table conforms to UL 60950-1, CSA-22.2 No. 60950-1, and IEC 60950-1. Any of the defined
optional equipment can be added to the AIT Table without any additional safety hazards being introduced
and there is no disposal of any waste products associated with the AIT Table.

5. Remove the four (4) M8 screws and four (4) M8 lock washers from the table plate bracket. Leave the
grounding screw remain attached to the bracket. Repeat for the other bracket.
Figure 3.5: Remove Fasteners from Table Plate Brackets.
6. Remove P-clamp from the plate.
Place a motorized table leg column on its side at an incline, with its top interface (to the bracket)
upwards. Place a padding/weight under the top portion, and another weight (such as stack of papers)
on the floor at the leg base (to prevent the leg from sliding downwards). Tilt the bracket to face up,
and secure the leg column onto the bracket, using the shorter four (4) M6X20 screws. Align the holes
in the bracket with the ones in the leg, as shown in the second picture below.
Make sure that the leg is oriented with its cable facing inward towards the control box, and that the
leg is securely fastened on the bracket.
Repeat above step for the other bracket and leg.
Figure 3.6: Install Brackets onto Both Legs.
7. Put the table bracket down onto the tabletop. Re-attach the table bracket onto the top using the
previous M8 screws and lock washers. Repeat this step for the other bracket and leg.

8. Place a foot onto the end of a leg. Install the longer four (4) M6 X 40 screws through the bracket into
the motorized leg. Tighten securely. Repeat for the other leg.
Figure 3.8: Install Feet Bases onto Leg Columns.
9. Open the clamp next to the bracket, to route the black leg cable through it. Plug the leg cable into the
mating connector of the control unit. Secure the clamp and the cable onto the table top. Repeat for
the other leg cable.

per the instructions provided with the Keyboard Shelf Assembly.
11. Remove padding from the switch panel, and snap the switch panel onto its interfacing metal bracket,
which is mounted just under the table. Ensure that the switch panel is easily accessible. Ensure that
all cables are properly connected.
Figure 3.10: Install Switch Panel.
14 2025001032 Revision L, 10/16
12. Carefully turn the table over so the feet are down and move the table into the desired location in the
room. If using glides, adjust them on the feet to achieve a level condition. If using casters, lock them
when table is placed at desired location.
Figure 3.11: Table is now assembled.
13. Plug power cable to outlet. Using the switch panel, operate the table up/down to move it into desired
height position setting, using the up/down arrow respectively.
If table reset is needed, perform system initialization procedure in Section 6.6. More functionalities
of the switch panel can be found in System Operation Section 6.
WARNING:
To prevent damage to the unit, lift by the main tabletop. Do not
lift the unit by the curved keyboard top.

4. ASSEMBLY - FOR AIT-W1/W2 ONLY
NOTE: Both AIT-W1 and AIT-W2 Tables arrive pre-assembled in shipping box.
4.1 Table System
1. Unpack the AIT-W Table and allow the unit to come to room temperature.
Use Figure 1.2 to identify the main components.
2. Move the table to the desired location in the room by lifting the side of the tabletop.
Place the back of the table close/flush to the wall.
NOTE: At least two people should perform this task.
If moving the table to a far location, a dolly is recommended to be used,
Figure 4.1: Unpacking AIT-W
(AIT-W1 is shown in this Figure)
3. Plug power cable to outlet. Using the switch panel, operate the table up/down to move it into desired
height position setting, using the up/down arrow respectively.
If table reset is needed, perform system initialization procedure in Section 6.6.
More functionalities of the switch panel can be found in System Operation Section 6.

5. Installing Instruments
The instruments that connect to the AIT Table must be mounted and configured properly before
operation. The AIT Table was designed for Topcon instruments. Consequently, adjustments may
be required for other brands of instruments and/or tools.
5.1 General Instrument Installation
1. Lift and place the diagnostic instruments onto the main tabletop. Adjust the level of
the instrument. Route the power cable down through one of the wire grommets in the
table and if required into the wire channel. Plug into the power strip supplied with
the table or a facility power source.
5.2 Computer System (Where Applicable)
1. Place the CPU into the CPU bracket assembly (optional) if equipped. Plug into the
power strip supplied with the table or a facility power source.
2. Place the reduced-size keyboard and mouse on the pivoting keyboard shelf. Pivot the
keyboard by loosening the locking knob (on the underside), and re-tightening it once
in the desired position. Cabling may be routed through the wire channel(s)
underneath the table. Connect all computer-related cables and raise the table to
ensure that enough cable slack is provided to allow a service loop to the CPU. If the
cables are too short, extension cables may be required.
5.3 Power Up
1. Plug in the power cord, and observe the initial height displayed (inches for 120 VAC
units and cm for 230 VAC units). Refer to the operation section of this document for the
details.
2. Turn ON all the instruments placed on table. Check the functionality of all the
components. Refer to the documentation supplied with each individual instrument for
operation details.
3. Once satisfied with the connections of all the instruments, see the next section, SYSTEM
OPERATION, for details using the system.
WARNING: Check all power cords and electrical connections for damage prior to
powering up the system.

2025001032 Revision L, 10/16 17
6. SYSTEM OPERATION
Each of the desk system switch panel control buttons performs a specific function. Ensure that the
table system is properly plugged in. See Section 5.3.
Those functions and additional information are identified in the following paragraphs. See Figure 6.1
for an illustration of the control panel.
Figure 6.1: Desk System Switch Panel
6.1 Up/Down Buttons
The UP arrow drives the synchronized legs UP. The down arrow drives the synchronized legs
DOWN.
6.2 Storage (Memory) Button
The storage (S) button is used to program a desired table height in memory.
6.3 Position Buttons
The position buttons (∙, ∙∙, and ∙∙∙) which denote numbering of (1, 2, and 3) respectively,
allow a particular height to be stored in memory so that a user can return to the same position
easily. Pressing and holding the button will move the table to that pre-programmed position.
To program a position in memory, move the table to the desired height, press and hold the
storage (S) button until an “S” appear on the display, and then press on a specific position
button to store the height memory (the button number will appear on the display next to the
S). The height is now recorded.
6.4 Display
The Display shows the relative height of the table. 120 VAC units will display the height in
inches. 230 VAC units will display the height in centimeters. The display will turn off after
some time if no buttons are pressed.
