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
· The power on state is entered whenever the power is
trued on while pressing the [BAND] key.
· All functions are initialized and activated in the all light-
ing mode.
· 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.
· E2PROM check(Etype 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
· The mute control is not activated when the mode is
switched.
· The test mode will be terminated by plugging it off the
power source or by initializing it when all the settings
will be initialized.
· During the test mode, it can be operated in a special
manner that is deferent 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 CON-
TENTS).
· Channel space will be no changed in the test mode.
