[___]:
adjustment for repair.
Total current is measured witn no cassette installed.
Power voltage is dc 3 V and fed with requrated dc power
supply from battery terminal.
e
Voltage
and waveforms
are dc with
respect to ground
in playback mode.
no mark: FWD, FM
e
Voltages are taken with a VOM (input impedance 10 MQ).
Voltage variations may
be noted due to normal produc-
tion tolerances.
