resistance measurements shall be carried out (exposed parts are acceptably
insulated from the supply circuit) before the appliance is returned to the customer.
The DC voltage is an actual reading measured with a high impedance type volt-
meter with a cassette loaded at playback mode. The measurement value may
vary depending on the measuring instruments used or on the product. Bias circuit
DC voltage is measured while in the record mode.
