Disassembly prohibited

WARNINGWARNING

If any abnormal smell or sound, or overheating or smoke should be detected, turn off the instrument immediately and then unplug it. If it should continue in use, a fire may break out on the instrument resulting in its malfunctioning. Contact the Kowa dealer where you purchased it or your nearest repair shop for inspection.

When replacing the fuse, make sure the instrument is turned off and unplugged from the socket. If the fuse holder cover is removed with the instrument unplugged, there may occur electrical shock.

Make sure that the power plug or AC adapter is properly inserted into the outlet. If not, there may occur a fire or electrical shock.

Use a fuse provided as accessories or a designated one. Otherwise, the instrument may malfunction or a fire may break out.

Make sure that the instrument is properly grounded to protect the body. Put the plug in the three-core socket with ground wire. Otherwise, there may occur electrical shock.

Install at a location away from, for instance, a cup containing liquid. If liquid should be spilled into the instrument, there may occur electrical shock. If so, turn off the instrument and then unplug it from the outlet. Contact the Kowa dealer where you purchased it or your nearest repair shop for inspection.

Do not disassemble, modify or repair the instrument yourself. Otherwise, there may occur a fire, electrical shock, instrument malfunctioning or any injury to the body. Contact your Kowa dealer where you purchased the instrument for repair. The product assembled by yourself will not get warranty or any other service.

Prohibitory

The outlet or plug board must not be loaded in excess of its rated capacity. If the main power cord should share an outlet with many other devices, there may occur a fire or electrical shock.

Inserting or guiding into the interior of any metallic object through an air vent slot or opening may cause a fire or electrical shock resulting in malfunctioning.

Do not damage the power supply cable. If the power supply cable is damaged,it becomes the cause of a fire or an electric shock. Do not modify the power supply cable. Do not carry a heavy thing on the power supply cable and do not pull it. Do not bring the power supply cable close to a heat equipment and do not make it to overheat.

Use a lamp provided as accessories or a designated one. Otherwise, there may result malfunctioning or a fire.

Do not short-circuit the terminals of the main unit's charger or a power pack charger. Keep each charging board away from any metallic object such as any clip and nail to avoid a fire or electrical shock.

Prohibitory

Caution

For unplugging from the outlet, pull the power cord out of it while holding the plug with your hands. Otherwise, there may occur a fire or electrical shock.

Do not put in, or pull out of, the outlet, the plug with your wet hands to avoid electrical shock.

Do not install the instrument unstable locations, for instance, on a shaky base or a tilting surface. Otherwise, if it should drop off or fall over, the body may be injured.

Do not replace the illumination lamp by the new one immediately after its service. Otherwise, you may burn your fingers due to its high temperature. Allow 30 minutes or so to cool it off before replacement.

The air vent must not be obstructed. Such obstruction will cause internal temperature to increase resulting in occurrences of breakdown, malfunction or a fire.

When in use, keep the instrument away from any high-level source of moisture, dust, soot or steam. Otherwise, there may result a fire or electrical shock.

Do not touch the instrument or power pack with your wet hands. Otherwise, there may occur electrical shock.

Unplug

Prohibitory

If there is no need to use the instrument for a long period of time, unplug the power cable and power pack for storage. Otherwise, there may result a fire.

Properly mount the power pack in place. Otherwise, if it should accidentally drop off, you may get injured.

Do not touch by hand a power pack while charging it, or the power source for a long time, because its temperature may increase. If the skin should keep touching the power pack or power source for a long time, it may get burned at a relatively low temperature though.

Keep your fingers off the gap between the rotary arm and the coupled arm. Otherwise, the fingers may be pinched and injured.

Keep your fingers off the gap around the prism box. Otherwise, when adjusting eye-to-eye distance, they may be pinched and injured.

Before operating or carrying it around with you, fix the main unit holding it with your hand securely. Otherwise, if it should accidentally drop off, you may get injured.

Do not keep the lamp operating for a long time to avoid a burn your may suffer from a hot lamp-house.

Prohibitory

When operating the forehead rest fixed with locking screws, tightly fasten them beforehand, to keep them from slackening during operation. Otherwise, the forehead rest may accidentally jerk toward you to get you injured.

Operational precautions for safety and accident prevention in use of battery

Kowa's SL-15 uses a lithium ion battery in its power pack. Always take the following precautions to avoid a serious injury or burn caused by fluid leakage, heat build-up, ignition and explosion as well as occurrence of a fire.

If any irregularity or fluid leakage should occur:

● Immediately move the battery further away from fire. Otherwise, leaked fluid or gas may catch fire and explode.

● If battery fluid got into your eye, rinse it off with clean water and see your doctor at once.

● If your body or clothes should be contaminated with battery fluid, wash it out.

Danger

Do not put into fire, short-circuit or disassemble the battery. Do not heat it in a microwave oven or conventional oven. Do not carry with you, or store, the battery together with metallic objects such as coin, hairpin and necklace

Prohibitory

to avoid short-circuiting.

Do not leave behind, or charge, the battery, for instance, near a fire, under a burning sun or in a car reaching a high temperature.

Do not charge the power pack with an other than designated battery charger. Do not charge an other than designated power pack.

Prohibitory

Obligatory

Do not use or charge, the power battery wet with fluid such as freshwater, salt water, milk, refreshing drinks and soapsuds.

WARNINGWARNING

Because the protective circuit for preventing any danger inside of the power pack may accidentally break down, do not leave behind, or charge, the power pack, for instance, near a fire, under a burning sun or in a car reaching a high temperature.

Do not shock the power pack hard, for instance, knocking with a hammer, stamping underfoot or letting it drop off.

Do not moisten the power pack with fluid such as fresh water, salt water, refreshing drinks and.

Caution

Mount the power pack on the instrument or battery charger, in a proper direction.

If , when it is exhausted, there is no need to use it for a long period of time, remove it from the instrument.

Recommended practice of battery disposal:

A lithium ion battery can be recycled. If a power battery you have will not be used any longer, it is recommendable to cover its contacts with insulating tape (for instance, cellophane tape) before taking it to Kowa, Kowa's dealer where you purchased it or any recycling operator.
