1. Operating environment
1) Instrument should be operated only by qualified and trained personnel.
2) Handle the instrument with care, and do not apply strong shock to the instrument.
3) Avoid high temperature and humidity, direct sunlight, and dust when installing and storing the instrument. Strictly
observe the following environmental conditions.
Operating Transporting and storing
Environmental temperature 10 to 35 °C -10 to +55 °C
Relative humidity 30 to 90% 10 to 95%
Atmospheric pressure
800 to 1060 hPa
700 to 1060 hPa
4) Avoid condensation when using, transporting or storing the instrument.
5) Do not connect a digital camera other than that supplied with this instrument. Using another camera may adversely
affect the safety or performance of this instrument.
6) Install the instrument in a room where the lighting is 5 lux or less, which make letters on this manual barely readable.
2. Precautions for electric system
1) When the instrument has not been used for a long period of time, inspect the items below.
Make sure the objective lens is free from soils.
Make sure the intensity of the lamps can be adjusted appropriately.
2) Install the system in a location where there is little risk of the plug being pulled out while operating. If the plug should
be pulled out accidentally, be sure to turn OFF the main power before plugging the instrument back in.
3) Kowa is not liable for malfunctions and/or damages resulting from maintenance and/or repairs performed by the
third party other than an agent authorized by Kowa.
4) Kowa is not liable for malfunctions and/or damages resulting from maintenance and/or repairs using parts other than
repair parts specified by Kowa.
5) The input voltage should always be maintained within ± 10% of the rated voltage.
6) Do not turn ON the flash lamp and adjust flash intensity at the same time.
7) Wait approx. 15 seconds to stabilize the power unit after turning the power ON before using the switches on the
operation panel.
8) Do not turn the main power ON and OFF in succession. Allow an interval of at least 10 seconds before turning the
main power ON and OFF.
9) Be sure to turn OFF the main power before connecting an external device.
10) Do not touch the patient and connectors at the same time as it may adversely affect the safety.
11) Using alcohol, disinfect the parts accessible by the patient.
12) The power supply must be provided for the sole use of this instrument.
3. Precautions when using a digital camera or this instrument
1) Carefully handle the objective lens as soiled or scratched parts of an objective lens may be imaged as white spots.
2) Always cover this instrument and the digital camera when not in use.
3) Do not apply strong shock or force to the objective lens.
4) Set a dial or knob with clicking positions to its designated position. The dislocated diopter compensation knob may
result in a photograph with a missing part or underexposure.
5) Securely install the digital camera. The digital camera installed insecurely may cause distortion of an image or
misalignment of focus.
The digital camera installed insecurely may fall off and become unusable.
6) Never disassemble or adjust this instrument or the digital camera by yourself as it uses precision parts which
requires special tool for doing so.
4. Disposal precautions
When disposing, this instrument and/or its consumables is categorized as industrial waste; therefore, the disposal must
be handled by a licensed industrial waste disposal contractor.
5. Replacement of the Aluminum Electrolytic Capacitor
The aluminum electrolytic capacitor for the flash lamp, which is used in the power supply section of this instrument,
is a component requiring regular replacements. The useful life of this type of components may be significantly reduced
depending on the frequency and conditions in which this instrument is used. If the capacitor is used beyond its useful life,
its electrolytic solution may leak or drain, which can result in abnormal odor, smoke, bursting sound, and other failures.
The design life of the capacitor is 50,000 flashes when used in an ambient temperature of 25°C. This is, however, only
a guideline, and the capacitor may need to be replaced earlier depending on the usage environment. In order to ensure
safe and stable operation of this instrument, early replacement of the aluminum electrolytic capacitor is recommended.
Replacement of components requiring regular replacement, such as aluminum electrolytic capacitor, is supported as a
paid service. For more information about replacement of such components, please contact Kowa or your Kowa dealer.
