device to a remarkable drop in performance or damage its parts.
Do not install the device where a large amount of steam rises,
such as in the bathroom or kitchen.
Avoid installing this device where dew condensation occurs. If the
device is installed in such places, it may result in electric shock or
malfunctions.
Do not install the device where acidic or alkaline solutions or
chemical sprays are used frequently.
Doing so may lead to electric shock or malfunctions.
When installing the device in a hospital, communication station, or similar place, provide sufficient protection against noise.
An inverter equipment, private power generator, high-frequency medical equipment or radio communication equipment may interfere with the
normal operation of this device. On the other hand, the device may affect such equipment by creating noise that disturbs medical treatment or
image broadcasting.
Do not put tension on the power supply wires.
If tension is put on the wires, they may break and result in
excessive heat and/or fire.
Do not immerse the device in water.
Doing so may lead to electric shock or malfunctions.
Do not install the device where the temperature may become
more than 40°C [104°F] or less than 0°C [32°F] or it will be
subjected to direct sunlight.
If the device is installed in such place, it may result in deformation
or malfunctions.
Use standard products with the proper current capacity.
The use of non-standard wires may result in current leak,
excessive heat, and/or fire.
Do not touch the main board with hands or tools. Prevent dust
from forming on the board.
