CAUTIONS

1. Prevention of Electric Shocks, Fire Hazards and Damage
1) Even when the POWER switch is set to STANDBY, a very

small current will flow. To save power and for safety when
not using the unit for an extended period of time, disconnect
the power cord from the household AC outlet. (for the J ver-
sion)
Set the

POWER switch to the OFF position when not in

use. (for the B version)

2) Do not handle the power cord with wet hands.
3) When unplugging from the wall outlet, always grasp and pull

the plug, not the power cord.

4) Consult your nearest dealer when damage, disconnection, or

contact failure is found with the cord.

5) Do not bend the cord sharply, or pull or twist it.
6) Do not modify the power cord in any manner.
7) Do not remove screws to disassemble the unit and do not

touch anything inside the unit.

8) AC power cord (For the J version only)

The AC power cord of this unit has certain one-way direction
connections to prevent electric shock. Refer to the illustration
for correct connection. (Fig. 1)

outlet and consult your dealer.

12) Do not block the ventilation holes of the unit so that heat can

escape. Do not install the unit in a badly ventilated place.

out or when the unit is not in use for an extended period of
time.

DETECTION RECORDING PROCESSOR) system (compact
disc  cassette deck, etc.) to enable setting the opti-
mum recording level automatically. Refer to these instruc-
