ASSEMBLY PROCEDURE
ASSEMBLY PROCEDURE
ASSEMBLY PROCEDURE
No special tools are required. Included tools are:
• Large screwdriver
• Small screwdriver
• Phillips screwdriver
• Wrench (not supplied with unit model slit lamps)
(1) Mounting the Table
(a) To attach the table on the instrument table AIT-15, use the four 8×24mm bolts with locking
washers.
* Raise the table to allow the bolts to pass through the mounting flange.
* Place the table on the mounting flange of the instrument table and screw the bolts into the
mounting bracket. The controls of the power supply should face the practitioner. Tighten the
bolts securely with the included wrench.
(b) To secure the unit model table to the ophthalmic unit.
* Peel off the tape which secures the plastic washer to the mounting bracket's shaft.
* Insert the shaft of the mounting bracket into the hole of the arm on the ophthalmic unit. The
plastic washer should be between the mounting bracket and the arm.
Note: The power supply is attached to the left side of the unit top (practitioner's view). If the
ophthalmic stand is located to the left of the ophthalmic chair, the power supply must
be relocated to the right side of the unit top to prevent interference with the arm. In this
instance, remove the four wood screws which attach the power supply to the unit top,
re-position the power supply in a similar position to the right side of the unit top, and re-
attach the power supply with the four screws.

ASSEMBLY PROCEDURE
(2) Mounting the Chinrest
* Remove the four screws which are attached to the chinrest mounting plate with the Phillips
screwdriver.
* Place the chinrest cord in the gap between the chinrest mounting plate and the chinrest
assembly. While making sure that the cord is not being pinched by the mounting plate, re-
tighten the previously removed screws.
(3) Mounting the Base Assembly and Rail Covers
* After checking to see that the main unit moves smoothly on the rails, remove the four screws
which are attached to the rails with the screwdriver. Place the rail cover to the rail, and
retighten the previously removed screws.

ASSEMBLY PROCEDURE
(4) Mounting the Illumination Arm
* Loosen the illumination arm locking knob which is located on the base assembly.
* Turn the brass bearing on the arm support shaft so that the red dot is 30° to 90° from the
shaft index.
* Loosen the set screw in the illumination arm with the small screwdriver.
* Lower the illumination arm carefully into position while lining up the two red dots.
* When the dots are properly aligned, retighten the set screw firmly to properly secure the illu-
mination arm to the shaft of the base assembly.
(5) Mounting the Microscope
* The microscope body has a notched groove and tapped screw-hole in the bottom of the cen-
tral barrel section. While firmly holding the microscope from the top, place the body assem-
bly on the microscope arm matching the notched groove with the stopper on the arm.
* Support the microscope with one hand and tighten the microscope attachment screw
securely onto the body with the large screwdriver.
Note: Avoid touching the front lens of the microscope or the lens surface of the eyepiece.

OPERATION PROCEDURES
OPERATION PROCEDURES
PREPARATION-DIOPTER COMPENSATION AND INTERPUPILLARY DIS-
TANCE ADJUSTMENT
Before using the instrument, always carry out the diopter compensation and interpupillary distance
adjustments.
(1) Use of the focusing test rod
The focusing test rod, which is a standard accessory, is used to establish the proper micro-
scope settings for each use.
The rod is inserted in the hole, which normally contains the Hruby lens guide plate. Place the
rod in the hole and turn it so that the flat black surface is perpendicular to the microscope's
objective lens.
(2) Preparation of illumination unit
Turn the power switch ON and place the brightness adjustment knob in an intermediate posi-
tion, then set the slit width control knob so that slit is approximately 2 to 3mm wide.
(3) Diopter compensation
To establish the current dioptric setting:
* First, turn the eyepiece ring in a counterclockwise direction until it stops.
* Now, turn the ring in a clockwise direction until a sharp, slit image is seen on the focusing
test rod.
