Components identified by mark have special characteristics
important for safety. Furthermore, special parts which have
purposes of fire-retardant (resistors), high-quality sound
(capacitors), low-noise (resistors), 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.
- Ground the soldering iron.
- Do not touch the pins of IC, LSI or VLSI with fingers directly.

READ CAREFULLY BEFORE ATTEMPTING ALIGNMENT
1. Set volume control to maximum.
2. Set band switch to MW, SW, AM and FM.
3. Set function selector to radio.
4. Set fine tunning to centre.
5. Set power source voltage to 6V DC.
6. Output of signal generator should be no higher than necessary to obtain an output reading.
