11. Other specifications
• Automatic panel closing when a tape/CD is inserted is
inhibited. (M&T model)
• Panel operation by turning power OFF/ON is inhibited.
(M&T model)
• Messages such as "CODE OFF" are not displayed
when power is turned ON.
• Pressing the ATT key opens or closes the panel. (M&T
model)
• Pressing the TI (AUTO) key during changer operation
turns 2zone ON. 2zone can be turned OFF by pressing
the TI (AUTO) key again. The P/S dot lights while 2zone
is ON.
• Pressing and holding the CLK key for a second in the
ALL OFF status the Mask Key (security) write mode.
• Security-related information
1. Forced Power ON mode (All models)
Even when the security (Mask key) is approved, resetting
the unit while holding the ATT and Preset 4 keys makes it
possible to turn the power ON for 30 minutes. After 30
minutes have elapsed, it is not possible to return to the
previous condition unless the unit is reset again.
2. Method of registration of the security code after EEPROM
(Tuner Unit Ass'y) replacement
(Code security model)
(1) Enter the test mode. (See " 1. How to enter the test
mode")
(2) Press the CLK key to enter the security registration
mode.
(3) Enter the code using the Preset 1/2/3/4 keys.
Example: To enter "3510"
• Press the Preset 1 key 4 times.
• Press the Preset 2 key 6 times.
• Press the Preset 3 key twice.
• Press the Preset 4 key once.
(4) Press and hold the DISP key for 3 seconds until
(5) Exit from the test mode. (See " 2. How to exit from the
(Note) All Clear is not applicable to the security code of
3. Simplified method of clearing the security code (K Type
(1) While the code entry is requested, press and hold the
VOL UP key for 3 seconds while holding the DISP
key pressed. (This should turn "----" off.)
(2) Enter "KCAR" from the remote. (Same way as the 00
model)
Press the 5 key on the remote twice, then press the
Track Up key. (This enters "K".)
Press the 2 key on the remote 3 times, then press the
Track Up key. (This enters "C".)
Press the 2 key on the remote once, then press the
Track Up key. (This enters "A".)
Press the 7 key on the remote twice, then press the
Track Up key. (This enters "R".)
(3) The security code is cleared and the unit enters the
ALL OFF mode.
(4) If you commit a mistake in the code entry, the unit
enters the code request mode again.
4. Method of writing the Mask key while the EEPROM is in
the initial status
(1) Enter the test mode. (See " 1. How to enter the test
mode")
(2) Press the CLK key to enter the Mask key registration
mode. "TRANSMIT1" should be displayed now. The
display at this time should show " < > " in place of " [ ]
".
(3) Point the Mask key remote toward the light sensor,
and press and hold its key for more than 0.5 second.
(4) When "TRANSMIT2" is displayed, press and hold the
key on the Mask key remote for more than 0.5 second
again. The first and second counter codes are not
compared at this time.
(5) When "APPROVED" is displayed, the write operation
is complete. Now the demonstration mode is initiated
and the test mode is terminated.
(Note) In the same way as previous models, if 30 minutes
have elapsed with no code written, an error occurs
and the power is turned OFF.
5. Method of initializing the Mask key
(How to reset the unit from the Mask key approved condi-
tion to the factory condition)
(1) Enter the test mode. (See " 1. How to enter the test
mode")
(2) "TRANSMIT1" is displayed and the Mask key entry
request mode is initiated.
The display at this time should show "
✽ ✽
" in place of
" [ ] ".
(3) Press and hold the key on the Master key remote for
more than 3 seconds.
(4) When "TRANSMIT2" is displayed, press and hold the
key on the Master key remote for more than 3 sec-
onds again.
(5) When "APPROVED" is displayed, the Mask key is
cleared, the demonstration mode is initiated, the test
mode is terminated and the unit returns to the factory
condition.
6. Method of clearing all Mask key-related data
(1) Enter the test mode. (See " 1. How to enter the test
mode")
(2) Press the CLK key to enter the Mask key registration
mode. "TRANSMIT1" should be displayed now.
(3) Point the Master key remote toward the light sensor,
and press and hold its key for more than 3 seconds
(until the level display shows the full condition).
(4) When "TRANSMIT2" is displayed, hold the key on the
Mask key remote for more than 3 seconds again.
If "TRANSMIT1" is displayed in place of "TRANS-
MIT2", restart the procedure from step (3).
(5) When "APPROVED" is displayed, all security data is
cleared and the unit returns to the condition before
Mask key writing with the EEPROM in the initial sta-
tus.
