SETTING THE VOLTAGE - 120 / 230 VAC

The XCEL slit lamps can be operated at 120 or 230

VAC. However, in order to ensure proper protection of the internal circuitry, the installed fuses should correspond with the operating volatage. For 120V operation, the fuses are T400mA, 250V (5X20mm fuses. For operation at 230VAC, the fuses are T200mA,

250V (5X20mm). Check the fuse holder to ensure the correct operating voltage shows in the window.

NOTE: Some older slit lamps have a voltage selector type power supply. The fuses for this power supply are

T250mA, 250V (5X20mm) for 120V operation and

T125mA, 250V (5X20mm) for 230V operation.

More information on replacing the fuses can be found in the maintenance section on page 9 of this guide.

INSTALLATION

The slit lamp is shipped in a multi-layer foam container and it is divided into major components: Microscope,

Instrument Body, Illumination Column, Table Top and

Chin Rest Assembly.

1.

Take out the various parts. Remove the wrapping.

Make sure the wrapping does not contain parts belonging to the instrument. Save the packing.

2.

Mount the headrest with the socket-head screws and hexagonal wrench (provided). Connect the transformer ground wire under one of the screws.

Ground Wire

6.

Position the slit lamp body on the table so that the geared rollers mate with the teeth on the guide rails. When the instrument is pushed forward or pulled backwards, the wheels should roll freely and evenly over the guide-rails.

7.

Place the guide-rail covers over the guide-rails.

Tightening the instrument base locking screw.

8.

XCEL 400 / 700 - Mount the illumination column onto the instrument body. To secure, insert screw and tighten with hex wrench.

Fuse Holder

Mounting the headrest and grounding wire

3.

Plug the wire from the headrest assembly into the connector on the back of the transformer.

4.

To ensure proper operation, check the fuse voltage setting on the power input module.

The factory setting is 120V. If 230V operation is desired, remove the fuse holder and pull out the white plasitc insert. Rotate the insert so "230" appears in the window when inserted in the fuse holder. Remove the 400 mA fuses and replace them with 200 mA fuses. See page 9 for fuse

types. Install the fuse holder in the power input connector.

Attaching the illumination column

8.

Mount the microscope head on the microscope arm by sliding it into position, making sure it is up against the stop. Then, tighten lock-knob located on the right side of the microscope.

10. XCEL 250 - Plug the cable from the lamp arm into the connector on the back of the transformer.

12. Connect the power cord to power supply and plug into a wall outlet or the instrument arm.

12560-101 Rev. F Page7

OPERATING PROCEDURES

1. Turn on the power using the On/Off switch located on the front of the power supply. Brightness can be adjusted by rotating the illumination level knob.

NOTE: The maximum position is for intermittent use only. Continuous use will shorten lamp life.

2. Insert the focusing rod in the pivot post of the instrument body to make rough PD and focus adjustments. Position the light onto the flat surface of the focusing rod and adjust the pupillary distance and focus of the eyepieces to suit the needs of the operator. Remove the focusing rod.

3. To position a patient, adjust the chinrest height by turning the control knob on the post of the headrest assembly until the patient’s canthus is in line with the canthus mark on the headrest post.

4. Microscope elevation is adjusted by rotating the joystick and observing the slit image through the microscope until the slit is centered on the patient's cornea.

5. Move the slit lamp with the joystick held firmly and slightly angled toward the patient, until the slit appears sharply on the cornea. The accuracy of this rough adjustment should be checked by the naked eye. The fine adjustment is performed while observing the slit through the microscope.

6. Tilt the joystick, which is now held lightly at its upper end, until the slit appears sharply at the depth of the eye which is to be observed. The horizontal motion of the base can be locked by tightening the base locking screw. Lock the base whenever the lamp is not in use.

7. The slit width can be adjusted by rotating the slitwidth control on either side of the instrument.

8. The angle between the illumination system and the microscope can be varied between 0 o and 90 o to either the left or to the right. The angle is indicated on the scale of the slit lamp arm.

9. Magnification is altered by rotating the dial on the microscope head. The magnification of each clickstop position is engraved on the dial.

Adjusting Slit Length - XCEL 400 / 700

The slit length is adjusted by rotating the slit length knob. The dial has seven stops for adjustments of 12,

9, 5, 3, 1 and 0.3mm diameter and a continuous length adjustment.

Adjusting Slit Length - XCEL 250

The slit length is adjusted by rotating the slit length dial.

The dial has five stops for adjustments of 13, 10, 6 and

0.3mm diameter and a continuous length adjustment.

Filter Dial - XCEL 400/700

The filter dial has five positions which are color coded as follows:

Blue dot = cobalt blue

Orange dot = open

White dot = heat absorbing

Gray dot = neutral density

Green dot = red-free

Filter Dial - XCEL 250

The filter dial has four positions which are color coded as follows:

Blue dot = cobalt blue

Orange dot = open

White dot = heat absorbing

Green dot = red-free

Slit Rotation - XCEL 400/700

By grasping the slit rotation knob, the lamp housing can be rotated. This, in turn, rotates the slit from vertical to horizontal in either direction. The slit positions are click-stopped in 45 0 increments and stopped at 0 0 and

180 0 and is indicated by the scale.

Slit Rotation - XCEL 250

Slit rotation is achieved by twisting the slit body to the left or right. The degree of rotation is indicated by the scale above the slit body.

Illumination Inclination - XCEL 400/700

The illumination unit can be inclined in the horizontal plane in 5 0 steps for a total of 20 0 . Tilt the illumination assembly by depressing the inclination latch release and pulling the base of the illumination assembly toward the operator.

Slit Centration - XCEL 400/700

When the centering screw is loosened, the slit can be scanned away from the center of the field of vision for retro-illumination, scleral scatter, etc. The slit image is centered again by tightening the screw.

MAINTENANCE

Forehead / Chinrest

For hygienic reasons, wipe the forehead rest and chin rest with an alcohol wipe after each patient.

Changing Bulbs

ENSURE THE SLIT LAMP IS SWITCHED OFF

AND REMEMBER THAT SOME PARTS MAY

BE HOT. DO NOT TOUCH THE GLASS OF

THE NEW BULB!

XCEL 400/700

To replace the bulb in the Xcel 400/700, loosen the lamp house locking knobs and lift off lamp housing cover.

Disconnect the 2 wires connected to the bulb. Remove the screw and bulb retaining clip and remove the bulb.

Insert the new bulb and secure it with the bulb retaining clip and screw. Connect the 2 wires to the pins on the bulb base and replace the lamp housing.

XCEL 250

Open the bulb access door. Swing the retaining spring toward the arm pivot and pull the socket and bulb from the housing. Note the position of the notch in the metal collar of the bulb. Replace the bulb with a new one.

Make sure the notch is in the same position. Insert the bulb and socket into the lamp housing and move the retaining spring back into position. Close the bulb access door.

Mirror Cleaning / Replacement XCEL 400/700
