1 Turn the Power switch OFF and remove the power cable from the AC power source.
2 Pry the fuse holder lid with a crosshead screwdriver. The fuse comes out.
3 Replace the fuse with a new factory-authorized fuse.
4 Reinstall the fuse holder in reverse order.

RESTOCKING CHINREST TISSUE

When the supply of chinrest tissue runs out, remove the chinrest tissue pins and replace the
tissue.

NOTICE

The socket may deteriorate due to the constant heat: it should
therefore be replaced after the lamps have been changed two
or three times.

CAUTION

When replacing fuses, first switch off the power supply and
remove the power cable to avoid electric shocks.

NOTICE

Use the glass tube fuse with the rating as stated on the side of
the fuse holder.

MAINTENANCE AND CHECKS

MAINTENANCE PROCEDURE

CLEANING REMOVABLE PARTS

Wipe the forehead rest, the chinrest and the patient grip (if a pair of patient grips is used) with
a cloth moistened with a tepid solution of neutral kitchen detergent.

CLEANING LENSES AND PRISMS

REMOVING STAINS

1 Prepare a solution of ethyl alcohol 20% and ether 80%.
2 Remove dust from the lens and prism surfaces with the attached cleaning brush, or a

blower.

3 Using clean gauze, lightly draw a spiral from the lens/prism centre outward.
4 If the stain remains, repeat this 2 to 3 times.
5 If stains are persistent, call your dealer or TOPCON (see the back cover).

CAUTION

Before carrying out daily maintenance, remove the power cable
(to avoid electric shocks) and wait until the body has cooled
down (to avoid burns).

CAUTION

To prevent burns, do not touch parts inside the lamp cover
house during operation and immediately after switching off the
power supply.

NOTICE

To prevent discoloration and deterioration in the chinrest,
forehead rest and other plastic parts, do not use volatile
solvents for cleaning, such as benzine, thinner, ether or
gasoline.
Wipe parts with a cloth moistened with a tepid solution of
neutral kitchen detergent.

NOTICE

To avoid damaging lens surfaces, do not use tweezers or
similar equipment to hold the gauze.

MAINTENANCE AND CHECKS

CLEANING THE SLIDING PLATE, RAIL AND WHEEL SHAFT

1 Wipe the wheel shaft clean by moving the base to the right and to the left.
2 Raise the control lever and wipe the sliding plate clean.

DISPOSING OF THE PRODUCT

For disposal of the instrument and consumables, contact a waste disposer or call your dealer
or TOPCON (see the back cover).

NOTICE

When stained, the sliding plate and rail of the table top and the
wheel shaft of the base move less smoothly. Clean them with
a dry cloth.

SPECIFICATIONS AND PERFORMANCE

ELECTROMAGNETIC COMPATIBILITY

This product conforms to the EMC standard (IEC60601-1-2:2001).

ELECTRIC RATING

Source voltage:100-120V, 220-240V AC, 50/60Hz
Power input: 160VA

SYSTEM CLASSIFICATION

• Type of protection against electric shocks: Type B applied part
Type B applied part is the applied part complying with the specified requirements of the
Standard IEC 60601-1 to provide protection against electric shock, particularly regarding
allowable LEAKAGE CURRENT.

• Type of protection against electric shocks: Class Ι equipment.

Class Ι equipment does not depend on basic insulation only for protection against electric
shocks. It can also be earthed; therefore, the metal parts with which one comes into contact
do not become conductive if the basic insulation fails.

• The mode of operation: continuous operation equipment.

• Degree of protection against ingress of water: IP x0
SL-D2, SL-D4 and SL-D4Z are the ordinary instruments (enclosed instrument without
protection against ingress of water).

• Methods of sterilization or disinfection recommended by the manufacturer: SL-D2, SL-D4

and SL-D4Z do not have any part to be sterilized or disinfected.

• Not AP or APG equipment.

PURPOSES OF USE

This slit lamp is used for enlargement in the observation of eyeballs and other parts.

OPERATION PRINCIPLES

Illuminates the observed part by the illumination light emitted from the illumination optical
system and allows enlargement observation by binocular stereoscopic microscope.
