*Use to adapt the plug on the power

cord to the shape of the wall outlet.
(Accessory only for regions where use
is necessary.)

Resetting the Microcomputer

If the microcomputer may malfunction (unit cannot be operated,
or shows an erroneous display) if the power cord is unplugged
while the power is ON, or due to some other external factor. If this
happens, execute the following procedure to reset the micro­computer and return the unit to its normal operating condition.

Unplug the power cord from the wall outlet, then plug it
back in while holding down the POWER key.

• Please note that resetting the microcomputer will clear the contents
of the memory and returns the unit to the state it was in when it left the
factory.

With the power cord plugged in, turn the POWER key
OFF. Then, while holding down the ON/STANDBY key,
press POWER.

1-2 INITIAL SETTING

The initial setting is performed when the AC power cord
is plugged into the AC power wall out let while pressing
the power (STANDBY) key.

3. TEST MODE

3-1 SETTING

Turn the power ON while pressing the [BAND] key.

3-2 CANCELLATION

Unplug the AC power cord from an AC power wall outlet.

3-3 STARTING ACTIVE CONTENTS

1 The power on state is entered when the power is

tuned on while pressing the [BAND] key.
All functions are initialized and activated in the all
lighting mode.

2 All lighting mode is canceled when any main unit’s

keys are pressed. The normal display obtained when
the selector is set to TUNER then appears.

3 E2PROM check(E,T,Q,type only).

Check the reading data and the writing data of the
E2PROM after setting the test mode.
Display shows blank if the reading data and writing
data are the same. Display shows ”LW” if the different
data will be written to E2PROM.

CAUTION: For continued safety, replace safety critical components only with man­ufacturer's recommended parts (refer to parts list). indicates safety critical com­ponents. For continued protection against risk of fire, replace only with same type
and rating fuse(s). To reduce the risk of electric shock, leakage-current or resis­tance measurements shall be carried out (exposed parts are acceptably insulated
from the supply circuit) before the appliance is returned to the customer.

The DC voltage is an actual reading measured with a high impedance type volt­meter as the AM/FM signal generator is specified to the conditions as shown in the
list below. The measurement value may vary depending on the measuring instru­ments used or on the product. The value shown in ( ) is actual reading measured
in the AM mode.

CAUTION: For continued safety, replace safety critical components only with manufactur­er's recommended parts (refer to parts list). indicates safety critical components. For con­tinued protection against risk of fire, replace only with same type and rating fuse(s). To
reduce the risk of electric shock, leakage-current or resistance measurements shall be car­ried out (exposed parts are acceptably insulated from the supply circuit) before the appli­ance is returned to the customer.

The DC voltage is an actual reading measured with a high impedance type voltmeter with no
signal input. The measurement value may vary depending on the measuring instruments
used or on the product.
