2. BACKUP
This function holds the current state of the unit even if the
AC power of the receiver is turned OFF.
(1) Operation outline
The backup state set command signal (CE) of a microcom-
puter is set low when the AC power is turned OFF. The
microcomputer detects the signal and enters the stop state.
The microcomputer is reset when the AC power is turned
ON. The data for backup state confirmation is checked by
reset processing.
The microcomputer is initialized when the data was
destroyed. If it is not destroyed, the microcomputer is started
in the backup state.
E
The data for backup state confirmation is written in a RAM
area.
E
The microcomputer is set to the STOP mode so as to
save the power consumption.
E
A backup state set command signal is detected by a timer
interrupt of 1 msec.
E
The backup guarantee period is set in a circuit.
(2) Backup state setting

The data (A596, 5A69H) for backup state confirmation is

4. TEST MODE
4-1. Initializing
The system is initialized when the power is turned on while
pressing the on/standby key.
(1) Contents of operation
E
All the functions are initialized.
4-2. AMP test mode using main unit's keys
4-2-1. Entering the AMP test mode
E
Turn on the power while pressing the BAND key.
4-2-2. Canceling the AMP test mode
E
By turning off the power, the system is initialized and the
test mode is canceled.
4-2-3. Contents of AMP test mode
(1) Automatic on/standby ON
E
The 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.
E
Sub-clock oscillation diagnosis function
The oscillation diagnosis (existence of oscillation and
measurement of period) of a sub-clock is performed
before the test mode is entered. If the diagnosis result is
OK, the system enters the test mode.
If the diagnosis result is NG, the oscillation of the sub-
clock is diagnosed again. If the result is OK, the system
enters the test mode. If the diagnosis result is continu-
ously NG five times, the system stops with ERR 1 and
ERR 2 displayed.
(2) All-lighting mode
E
All the fluorescent display indicators and LED lamps light
when the power is turned on while pressing the BAND
key.
E
After that, the all-lighting mode is canceled when any
main unit's key is pressed. The normal display obtained
when the selector is set to TUNER then appears.
(3) Others
E
The AMP test mode is not terminated even if the selector
is set to positions other than TUNER.
E
In the AMP test mode, the muting during mode selection
is not controlled. However, the operation during the
power-on sequence is the same as the normal operation.
E
The SP protection operation is also the same as the nor-
mal operation.
E
In the AMP test mode using main unit's keys, the keys
below provide a special operation according to the posi-
tion where the selector is set. The main unit's keys
except described below and the rotary encoder provide
the normal operation.

@
Write data in the unused area of E2PROM, then read the
written data. If the read data is the same as the written
data, "RAM OK" is displayed in the fluorescent display
indicator. If the former is different from the latter, "RAM
NG" is displayed.
A
Set the TUNER ATT to OFF and display the S level in
hexadecimal when the ENTER key is pressed. ("ATT

B
Set the TUNER ATT to ON and display the S level in
hexadecimal when the ENTER key is pressed. ("ATT ON
**" is displayed in the fluorescent display indicator.)
* The special display using the ENTER key is continued until
the next operation is carried out. (**: S LEVEL)
When keys other than ENTER are pressed in items

appears. The operation corresponding to the key that has
been pressed is performed in this case.

written data. If the read data is the same as the written
data, "RAM OK" is displayed in the fluorescent display
indicator. If the former is different from the latter, "RAM
NG" is displayed.
A
Set the TUNER ATT to OFF and display the S level in
hexadecimal when the ENTER key is pressed. ("ATT
OFF **" is displayed in the fluorescent display indicator.)
B
Set the TUNER ATT to ON and display the S level in
hexadecimal when the ENTER key is pressed. ("ATT ON
**" is displayed in the fluorescent display indicator.)
* The special display using the ENTER key is continued until

4-4. SERIAL TEST MODE
(1) Setting the serial test mode
The unit is put into the serial test mode when a serial code
"TEST ON" is input during the POWER-ON sequence.
In the 16-bit serial test mode, serial code C27FH is input.
E
In the serial test mode, all remote control keys and ordi-
nary serial codes are disabled. Only the panel keys per-
form the same operation as usually.
(2) Canceling the serial test mode
E
The serial test mode is canceled to return to the ordinary
mode by inputting a "TEST OFF" code (C27 EH). After
the ordinary mode was returned, the serial mode is
returned to the state before the test mode is entered.
The backup operation is not initialized.
E
The serial test mode is also canceled when the AC power
is turned OFF.
(3) Cautions
E
The serial test code is prescribed as a 16-bit code only.
E
The operations below are inhibited in the serial test mode.
The operations mentioned above cannot be guaranteed
when they are performed in the serial test mode.
E
An identical code is output when the serial test mode
code is input.
