Introduction

Warning
Prohibitory
Do not place a container or cup containing liquid near the instrument. Spilled liquid entering the
instrument may cause electrical shock. If liquid should enter into the instrument, turn OFF the
power switch immediately, unplug the instrument from the power outlet, and then contact Kowa
or your Kowa dealer for inspection.
Do not plug in or unplug the power plug while your hands are wet, as this may result in eleclic
shock. When unplugging the power plug, hold it rmly at the plug area. Do not pull directly on
the power supply cable, as this may damage or expose the cable's internal wiring, resulting in
risk of re or electric shock.
Do not load the power outlet or cable in excess of its rated capacity. If the main power supply
cable should share a power outlet with other devices and the rated capacity is exceeded, may
occur re or electrical shock.
Do not install the instrument in a place where it is difcult or impossible to unplug its power
supply cable. Otherwise, it may cause a re or electrical shock.
Do not insert any metal object into an air vent or opening of the instrument. It may cause in-
strument malfunctioning, re or electrical shock.
Disassembly prohibited
Do not disassemble, modify or repair the instrument yourself. It may cause a re, electrical
shock, instrument malfunctioning or bodily injury. Refer all servicing to Kowa or your Kowa
dealer. The product assembled by yourself will not be covered under warranty nor any other
service.
Obligatory
Only use the power supply cable supplied with the instrument. Otherwise, it may cause a re
or instrument malfunction.
If the power supply cable becomes damaged (if internal wiring is exposed, etc.), immediately
unplug the instrument from the power outlet. Continued use poses risk of re or electric shock.
Make sure to insert the power plug into the power outlet completely and securely. A loosely
connected electrical plug may cause a re or electric shock.
Do not damage, modify, or rest heavy object on the power supply cable. Damage to the
power supply cable may result in the exposure of live wires, re, or electric shock.
Regularly remove dust off the power plug. Dust accumulated on the power plug may absorb
moisture, which may result in isolation failure and cause re.
Make sure that the instrument is properly grounded to prevent bodily injuriy. Connect the
power plug into the three-wire grounding type outlet with ground wire. Failing to properly
ground the instrument may cause electric shock.
Use a designated fuse only. Using an undesignated fuse may cause a re or instrument
malfunction.
Unplug
If any abnormal smell, sound, overheating or smoke should be detected, make sure to turn
OFF the instrument immediately and then unplug the instrument from the power outlet. Con-
tinued use of the instrument may cause a re or instrument malfunction. Contact Kowa or your
Kowa dealer for inspection immediately.
Warning
High-Voltage
When replacing the ash lamp, make sure the power is turned OFF and then un-
plugged from the power outlet. Otherwise, there may occur electrical shock.
When replacing the huse, make sure to turn OFF the power switch and then
unplug the instrument from the power outlet. Replacing the huse without un-
plugging the instrument may cause electrical shock or burn.
This instrument is equipped with a storage capacitor for photography light.
Replacing the flash lamp while this capacitor is still not yet fully discharged
causes a danger of an electrical shock. Check that the discharge indicator LED
is turned OFF before replacing the ash lamp.

III
Caution
Prohibitory
Do not pull on the power supply cable when unplugging the instrument from the power outlet.
Doing so may damage the cable and cause a re or electric shock. Make sure to hold the pow-
er plug when unplugging the instrument.
Do not install the instrument on an unstable location such as on a shaky base or a tilting sur-
face. Otherwise, the instrument may drop or fall over causing a bodily injury.
Caution
High-
temperature
Do not replace the ash lamp immediately after turning the OFF the main power.
You could be burned by the lamp heated to a high temperature. Wait for more
than 10 minutes to cool the lamp down before replacing.
Do not touch the ash lamp bulb with your bare hand. Otherwise, ash intensity and lamp lon-
gevity may be reduced.
Do not increase the observation illumination light intensity more than required. Otherwise, the
eye may be injured.
Do not increase the ash intensity more than required. Otherwise, the patient may experience
pain and his or her eye may be injured.
The air vent must not be obstructed. Obstructing the air vent may increase the internal tem-
perature resulting in malfunctioning of the instrument or a re.
When operating this instrument, keep your ngers off the gap between the optical component
and the power supply or the chin rest support and the forehead rest support, or the gap under-
neath the chin rest. Otherwise, the ngers may be pinched and injured. Instruct the patient not
to place his or her ngers on the instrument.
Do not wipe the outer surface of the instrument with solvents such as benzene, or ether. Doing
so may cause discoloration or degradation.
Obligatory
The power supply must be provided for the sole use of this instrument. Sharing the same pow-
er supply with other external devices may cause instrument malfunction.
When moving the chin rest up or down to adjust the height of the examined eye, carefully op-
erate the instrument while checking the position of the patient’s head. A patient with a smaller
head may have his or her head caught between the components.
Make sure that the instrument are not in contact with the patient's eye or the nose when in op-
eration. Otherwise, the ptient may likely be injured.
Handle fuses with care. Otherwise, glass components may be damaged causing bodily injury.

manipulate the instrument while checking the position of the patients’ head.
A patient with the smaller head may get his or her head caught between the components.
D: The air vent must not be obstructed. Obstructing the air vent may increase the
internal temperature resulting in malfunction of the instrument or a re.
D: Do not insert any metal object into an air vent or opening of the instrument.
It may cause electrical shock and malfunctioning of the instrument.
Keep your nger off the spaces shown with an arrow. Otherwise, you may be injured.
