Risk of Electric Shock
There is a risk of electric shock during replacement of the low voltage power supply.
Use insulating gloves or avoid direct contact with any conducting part of the power supply, and caution should be
exercised during replacement.
The capacitor may take one minute to complete discharge after the AC cord is unplugged. Also, there is a possibility
that the capacitor doesn’t discharge because of a breakage of the PCB, etc., so remember the possibility of electric
shock to avoid electric shock.
