*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.
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.
