Congratulations on the purchase of your new XPERT SL 45 !

This instruction manual is designed as a training and reference manual for the

operation and maintenance of the instrument. We recommend that you read it

carefully prior to use and follow the instructions to ensure optimum

performance of your new instrument.

LABOMED XPERT SL 45 Slit Lamp is an all-in-one Ophthalmic instrument for

observation, measurement and diagnosis of Contact lens fitting, Anterior eye

segment, Cataract, Glaucoma, Retina etc.

Its ergonomic design also allows the XPERT SL 45 to be used in laser therapy,

this has been achieved by the possibility of operating the Slit projector in the

central position either with the left hand or right hand. The excellent

transmission of the optical system minimizes light loss during therapy.

Together with the excellent image quality, this provides ideal conditions for

crisp, crystal clear images of even the finest structure.

Considering standard work procedures, the design of this system provides you

with an optimum, ergonomically correct configuration.

The perfection of the observation system and outstanding operating

convenience ideally compliment each other. The outstanding benefits of this

design include a short working distance, comfortable arm and body posture,

easy to grip controls for the sensitive setting of the Slit length, width and

rotation. Using with joystick, you can control the XPERT SL 45 quickly and

precisely in all three coordinates and set it exactly in any position with a quick

action lock.

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 base from bottom of the

table top with the socket-head screws. and

hexagonal wrench (provided) as shown in Fig.

2. Connect the transformer ground wire under

one of the screws.

3. Plug the wire from the headrest assembly into

the connector on the back of the power supply

unit.

4. Attach head rest and chin rest assemblies with

the help of screw drivers as shown in Fig. 4.

5. Mount the table-top on appropriate instrument

stand arm or table base.

6. Position the Slit Lamp body gently 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. (Refer Fig. 5)

Tightening the instrument base locking screw.

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.

9. Plug the cable from the lamp arm into the

connector on the back of the power supply unit.

1. Turn 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 projection 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 projection rod and adjust the pupillary

distance and focus of the eyepieces till a comfortable

viewing is obtained. Remove the projection 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 slit-

width control on either side of the instrument.

8. The angle between the illumination system and the 0 0microscope can be varied between 0 to 90 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 click-

stop position is engraved on the dial.

10. Three filters are provided for cool and comfortable

view. This can be achieved by turning the filter dial.

1. Open the lamp house by opening the two screws (1)

& (2). See fig 8.

2. Open the lamp locking screw (2) to un-secure the

lamp holder. See fig 9.

3. Detach the power cord (1) from the lamp house.

4. Remove the lamp socket (2) from the lamp house.

Replace the blown lamp with live lamp and reverse

the procedure to secure the lamp house.

5. Open the fuse holder provided in the AC inlet on the

power supply.

6. The fuse holder has one live and one spare fuse.

Replace the dead fuse with the live fuse. Insert the

fuse holder back in the AC inlet plug.

7.1 Headrest / Chinrest Cleaning

For hygienic reasons, wipe the headrest and chin rest

with an alcohol wipe after each patient.

7.2 Changing Illumination Lamp

Ensure the Slit Lamp is switched Off and remember that

some parts may be hot. Do not touch the glass of the

new bulb.

Open the bulb access door. Swing the retaining spring

towards 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 the socket into the lamp housing and move the

retaining spring back into position. Close the bulb

access door.

7.3 Projection Prism Cleaning

Grasp the narrow shank of the projection prism and pull

upwards. When cleaning the prism, blow with clean, dry

air, then gently wipe with a soft linen cloth.

7.4 Cleaning the Slide Plate

If the plate is dirty, it may cause a rough feeling when

maneuvering the base of the Slit Lamp. Clean the slide

plate with soft cloth lightly dampened with a mild soap

and water solution.

CONTINUOUS POWER SUPPLY

The Labomed Slit Lamp can be operated from 120 to 230

VAC. This is achieved by universal power supply. So

there is no need of adjusting the settings according to

the supply line voltage of the destination country.

NOTE : Two fuses are used in this unit. This is

recommended to replace the blown out fuses with the

fuses of same rating and type i.e. T 2.5L 250

More information on replacing the fuses can be found in

the maintenance section of this guide.
