Battery current: /
- Volume minimum
24.2 mA (Radio)
- Volume maximum
30.9 mA (Radio)
Measurement Instruction:
RADIO: AM - 74 dB/m, 30% Mod; FM - 60 dB/m, 30% Mod.
- The voltage value and waveforms are the reference voltage of this
unit measured by DC electronic voltmeter (high impedance) and
oscilloscope on the basis of chassis. Accordingly, there may arise
some error in voltage values and waveforms depending upon the
internal impedance of the tester or the measuring unit.

- Importance safety notice:
Components identified by
important for safety. Furthermore, special parts which have
purposes of fire-retardant (resistor), high-quality sound
(capacitors), low-noise (resistor), etc. are used. When replacing
any of components, be sure to use only manufacturer's specified
parts shown in the parts list. /
Caution !
IC, LSI and VLSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care during repair.
- Cover the parts boxes made of plastics with aluminium foil.
- Put a conductive mat on the work table.
