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 i ntended to hold the diagnostic instruments and to faci litate the proper adjust ments 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. Installing Instruments
WARNING: Check all power cords and electrical connections for damage prior to
powering up the system.
!
The instruments that connect to the AIT Table must be mounted and configured properly before
operation. The AIT Tabl e was designed for Topcon i nstruments. Consequently, adj ustments may
be required for other brands of instruments and/or tools.
5.1 General Instrument Installation
1. Lift and place the diagnostic inst ruments 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 (Wh er e Applicable)
1. P lace the CPU into the CP U bracket assembly (optional) if equipped. Plug into the
power strip supplied with the table or a facility power source.
2. P lace the red uced-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
2. Turn ON all the instruments placed on table. Check the functionality of all the

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.
2025001032 Revision L, 10/16 17
6.5 Anti-CollisionTM Safety Feature
WARNING:
All service and repairs shall be performed by a qualified technician.
!
Anti-collision function is included in the table system for safety feature. If a “collision” with
solid object at any area under/above the table should occur while the tabletop is moving
down/up respectively, the table system will stop operation, start to run in the opposite
direction (~2in), and then make a complete stop. Remove the obstacle, and operate table
normally.
CAUTION: Safety feature may not activate if t he coll isi on occurs durin g initialization phases
(see Section 4.6), or within the first 1000msec or after the control unit button has been
released, or if the collision pressure is very low or with a soft object.
6.6 System Initialization (Optional)
NOTE: All new units are provided with complete initialized systems. Use this procedure only
for syncing or leg replacements.
To initialize Table system, press and hold the down button once or twice, and holding it down.
It will stop when reached the bottom, and then automatically run ~0.2in up/down again.
ONLY release the down button when movement has stopped completely. DO NOT place any
obstructions under the table during initialization of control unit. If button is released before
sequence completed, initialization process has been interrupted and must be restarted. See
Section 4.5.
7. ADJUSTMENTS
No periodic adjustments of the desk system are required. If problems arise, please refer to Section 9:
TROUBLE SHOOTING.
The instruments used with the desk system may require periodic adjustments and/or calibrations.
Refer to the documentation supplied with the appropriate instrument(s) for details.
8. MAINTENANCE
There are no periodic main tenance requirements for the AIT Table. However periodic checks of all
the functions, and power cords should be performed every six months. For operational detail, please
refer to Section 6: SYSTEM OPERATION.
If problems arise, please refer to Section 9: TROUBLESHOOTING.
It is recommended that the exterior surfaces of the AIT Table be cleaned with a mild soap, water, and
clean damp cloth to maintain a like-new appearance.
Cleaning shall be performed at least every six months.
18 2025001032 Revision L, 10/16
WARNING: All service and repairs shall be performed by a qualified technician.
9. TROUBLESHOOTING
!
