ASSEMBLY PROCEDURE

(1) Selecting Voltage and Fuse

* Check the setting on the voltage selector, which is located on the bottom of the power supply.

* If the selector does not match the outlet voltage, turn the selector to the proper setting with a

screwdriver.

* Turn the center of the fuse holder with the Phillips screwdriver, remove the fuse and check it's

rating. Insure that the fuse is the correct rating for the supplied voltage:

(except for U.S.A. and Canada) (for U.S.A. and Canada)

F1, F2: T1AL 250V(100, 120V) F1, F2: T1AL 250V(120V)

T500mAL 250V(220, 240V) T500mAL 250V(220V)

F3: F4AL 125V F3: F4AL 125V

(2) 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 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.

ASSEMBLY PROCEDURE

(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.

(3) 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.

ASSEMBLY PROCEDURE

(4) Mounting the Main Unit

* Place the wheels of the base assembly evenly on the table rails.

* After checking to see that the main unit moves smoothly on the rails, insert the rail covers in

the space between the rail and table.

* Remove the protective tape from the illumination unit and the hole cap while being careful to

avoid touching the lens surface.

(5) Connecting Cables

* Connect the chinrest cable, main body cable and power cable to the power supply.

* Remove the cable clips from the bottom of the table top, slip them over the chinrest and

power cables and re-attach them to the table.

ASSEMBLY PROCEDURE

(6) Installing the Chinrest Paper

* Remove the two pins from the chinrest.

* Place the pins through the holes in the chinrest paper. Remove the wrapping from the chin-

rest paper.

* Align the pins with the holes in the chinrest and secure the paper to the assembly.

(7) Accessory Box

* An accessory box is supplied to store the accessories.

CHECKING PROCEDURE

(1) Power Plug

* Make sure that the instrument is always properly grounded.

(2) Illumination and Instrument Functions

* Turn the power supply on and observe that the illumination is passing through the opened slit

controls.

* Check to see that the slit width and length controls, filter lever and magnification changer

lever operate smoothly and properly.

(3) After the installation is completed, turn the power supply off and cover the instrument

with the dust cover.

WARNING

To avoid fire and electric shock in case of leakage, be sure to use a

grounded outlet. Do not connect to outlets that are not grounded.

OPERATION PROCEDURES

PREPARATION-DIOPTER COMPENSATION AND INTERPUPILLARY DIS-

TANCE ADJUSTMENT

Before using the instrument, always carry out the diopter compensation and interpupillary dis-

tance 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.

Insert test rod in the hole in chinrest with the flat surface at the top of test rod facing the micro-

scope.

(2) Preparation of illumination unit

* Turn the power switch ON. Set the brightness control switch at the '0.1' position.

* Turn aperture and slit length control wheel until slit diameter becomes 14mm, then turn slit

width control knob to set slit width to maximum.

* Use joystick gross control to move base so that illumination is provided on the test rod.

* Then use joystick fine control to move base so that a 1 to 2mm width slit image focuses

sharply on test rod when seen naturally by eye.

(3) Diopter compensation

Independently set the diopter setting for each eyepiece as follows.

* First, turn the eyepiece ring in a counterclockwise direction until it stops.

* Now, turn the ring clockwise until a sharp image is seen through the microscope on the

focusing test rod.

Ring

OPERATION PROCEDURES

(4) Interpupillary distance adjustment

While looking through the eyepieces at the image on the focusing test rod, adjust the converg-

ing binocular's prism box, so that the image is fused and a stereo-scopic image results. For

operator comfort, since each eyepiece can be moved independently, insure that both eye-

pieces are at the same height.

PATIENT POSITION

Positioning patient's head

Have the patient place his chin on the chinrest and forehead against the forehead rest. Adjust the

chinrest adjuster so that the patient's outer canthus is at the approximate height of the canthus

marker.

BASE OPERATION

(1) Horizontal gross adjustment

To adjust the microscope's position horizontally, move the base while keeping the joystick in

the vertical position.

(2) Horizontal fine adjustment

For fine adjustment, such as alignment or focusing, tilt the joystick to the left or the right.

(3) Vertical fine adjustment

For fine vertical adjustment, turn the joystick clockwise to raise the microscope and counter-

clockwise to lower it.

OPERATION PROCEDURES

(4) Locking the base

To lock the base, tighten the base locking knob.

(5) Focusing

* Gross adjustment for alignment or focusing is done by the operation described in (1)

* Fine adjustment for alignment or focusing should be done by the operations described in (2)

and (3) above while looking through the microscope.

OPERATION OF THE ILLUMINATION UNIT

(1) Change of slit size

By operating the slit width control knob or turning the aperture and slit length control wheel,

ideal slit width, slit length and spot size can be achieved.

(2) Change of slit position

By turning the illumination unit or operating slit rotation control ring, the desired positioning of

the slit image can be obtained.

(3) Change of filter

A cobalt-blue filter or red-free filter can be set in the light path.

White mark -- No filter

Blue mark -- Blue filter

Green mark -- Red-free filter
