Precautions for using analog remote control
Keep in mind the following points when performing analog remote control.

The device may malfunction under the influence of noise, so make the wiring
used for control as short as possible.

The device may malfunction or break down due to inductive noise such as high
frequency waves, so do not run the wiring used for control near high frequency
power supplies.
* Caution is especially necessary when using the device at high voltage with a
floating ground.
Although this power supply is equipped with complete protection circuits,
application of excessive voltage or energy may lead to malfunction.
