(Using a Sony HF series cassette tape) *When using a Sony LR6 (SG) “STAMINA” alkaline dry batteries (produced in Japan) Note The battery life may shorten depending on the operation of the unit. For maximum performance we recommend that you use alkaline batteries. House Current Connect the AC power adaptor to DC IN 3V and to a wall outlet. Use the AC-E30HG AC power adaptor (not supplied). Do not use any other AC power adaptor. Polarity of the plug Notes Specifications for AC-E30HG vary for each area. Check your local voltage and the shape of the plug before purchasing. Do not touch the AC power adaptor with wet hands. Connect the AC power adaptor to an easily accessible AC outlet. Should you notice an abnormality in the AC power adaptor, disconnect it from the AC outlet immediately.

It is mounted on the MAIN board, and therefore the REC/ PLAYBACK on cannot be detected with the MAIN board removed. When making an operation check and voltage check of mechanical deck with the MAIN board removed, fix the S102 at turn on. MAIN BOARD (Component Side) SECTION 1 SERVICING NOTE Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur- ing repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam- aged by heat.
