1. Cautions for high voltage
High voltages from hundreds volts to tens of thousands volts are to be applied to the electronic
equipment such radio and radar devices. You do not face any danger during normal operation, but
sufficient cares are required for maintenance, inspection and adjustment of their internal components.
(Maintenance, check-up and adjustment of the inside of the equipment are prohibited except by
maintenance specialists.)
High voltages of tens of thousands volts are so dangerous as to bring an instantaneous death from
electric shock, but even voltages of hundred volts may sometimes lead to a death from electric shock.
When you touch any parts inside these devices, before doing so, you should make it a rule to turn off
the power switch to prevent such an accident caused by electric shock, and discharge capacitors with a
wire surely earthed on an end and make sure that internal parts are no longer charged. Furthermore,
when doing so, wearing dry cotton gloves protect you from such danger. It is also necessary to put one
of your hands in the pocket and not to use both your hands at the same time.
It is also important to select a stable foothold always to prevent secondary accidents once you were
electrically shocked. If you are injured from electric shock, you disinfect the burn sufficiently and give
medical treatment to it promptly.
