3. DESTINATION LIST OF TUNER
• TUNER
3-1 Channel Space Selector in Broadcasting set-
ting
1. Push the BAND key for 2 seconds in the standby mode.
2. Display shows "F100/A10kHz" or "F50/A9kHz" blinkingly
for 5 seconds.
3. Turn the VOLUME knob (Encoder) to choose your chan-
nel space.
4. Push the BAND key to memorize the channel space to
E2P ROM.
Note : Channel space will be set by the data from E2P
ROM if reconnect the power cord..
Channel space will be set by the destination data from
E2P ROM if backup data damaged.
4. TEST MODE
4-1 SETTING
Turn the power ON while pressing the [BAND] key.
4-2 CANCEL
Unplug the AC power cord from an AC power wall outlet.
4-3 STARTING ACTIVE CONTENTS
1The power on state is entered whenever the power
is turned on while pressing the [BAND] key.
All functions are then initialized and activated in the
all-lighting mode.
3All 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.
3E2P ROM check (E, T, Q, M, V type)
Check the reading data and the writing data of the
E2P ROM after setting the test mode.
Display shows blank if the reading and writing data
is the same. Display shows "&" if the different.
Data (FM 50kHz, AM 9kHz, De-emphasis 50us) will
be written to E2P ROM if the unit for M and V type.
4-4 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 (5.
contents).
4Channel space will be no change if set channel
space in the reset mode.
