Unplug the power cord, short the two prongs of the plug with a jumper wire, turn the power switch on, then measure the resistance between the jumpered plug and each exposed metal cabinet part with an ohmmeter.
Always unplug the AC power cord, use only manufacturer‑recommended replacement parts, check the condition of the power cord, and after service restore all lead dress, insulation barriers, and shields before returning the equipment to the customer.
The manual recommends using GR2032 (BAT501) batteries, either manufactured by Matsushita or Sony, as the correct replacement type.
