SAFETY PRECAUTIONS

Icons

CAUTION

Prevention item

“To prevent units from falling during use and movement, secure each unit.”

To avoid injury to the patient’s eye and nose, pay particular attention while operating the instrument body.

To prevent fingers from being caught between moving parts, beware of the moving parts while operating the main body.

To avoid causing the patient pain and damage to the patient’s eye, do not make the illumination too bright.

To avoid electric shocks, do not attempt overhauling, rebuilding or repairs. Contact your dealer for repairs.

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

If you replace the lamp immediately after switching it off, beware of high temperatures: they could cause burns.

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

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

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

The base contains strong springs. Do not attempt to disassemble or burn the base, as the springs could cause injury by shooting out of it.

To prevent items from falling during use and movement, attach optional accessories securely.

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.
