R-SE9/SE9T
[ AUTO key ] Selects the MUTE operation and equalizer
cyclically in the order below for operation display every time
this key is pressed.
-- -> MUTE operation -> Minimum -> Maximum ->
In the operation for except the AUTO key, become pre-
condition equlizer .
Pre condition : The equlizer becomes the condition to be
pushed the AUTO key before
(include N.B. circuit).
(6) SERIAL TEST CODE LIST
Refer to Service manual (B51-5210-00) of R-SA7 on
page 7.
[ BAND key ] Every time this key is pressed, all the displays
go off and the normal display is selected cyclically.
2-3. RDS test mode using main unit's keys
2-3-1. Entering the RDS test mode
• Turn on the power while pressing the N.B. key.
2-3-2. Canceling the RDS test mode
• By turning off the power, the system is initialized and the
test mode is canceled.
2-3-3. Contents of RDS test mode
• The POWER ON state is entered whenever the power is
turned on while pressing the N.B. key. All the functions
are then initialized.
• In the RDS test mode using main unit's keys, the keys
below provides 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.
Key
EX. BASS key
Performs the same operation as for
remote control key "DISPLAY" every time
this key is pressed.
MODE key
Performs the same operation as for
remote control key "PTY" every time this
key is pressed.
N.B. key
Performs the same operation as for
remote control key "TA" every time this
key is pressed.
ENTER key
Selects the display cyclically in the order
below every time this key is pressed.
1 Write data in the unused area of EEPROM, 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.

CIRCUIT DESCRIPTION
Pre-condition --
Operation
2 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.)
3 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 1 to 3
above, the TUNER ATT is set to OFF and the normal display
appears. The operation corresponding to the key that has
been pressed is performed in this case.
2-4. 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.
• 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
• 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.
• The serial test mode is also canceled when the AC power
is turned OFF.
(3) Cautions
• The serial test code is prescribed as a 16-bit code only.
• 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.
• An identical code is output when the serial test mode code
is input.
