Batteries (R06/AA) (2) *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 micro-

computer 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

ofthe memoryandreturns theunit tothestate itwas inwhen it leftthe

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

1The 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.

2All 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.

3E2PROM 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.

3-4 ACTIVE CONTENTS

1The mute control is not activated when the mode is

switched.

2The test mode will be terminated by plugging it off the

power source or by initializing it when all the settings

will be initialized.

3During the test mode, it can be operated in a special

manner that is different from an ordinary operation by

using the keys on the remote control or the main

body ,specifically as shown in the following table (3-5

CONTENTS).

4Channel space will be no changed in the test mode.
