• Panel open and closes with the ATT key. (M&T model)
• No displays such as "CODE OFF" during Power-ON.
• Pressing the TI (AUTO) key during changer operation turns
on 2zone. Cancel by pressing the TI (AUTO) key again.
The P/S dot is lit during 2zone.
• Pressing the CLK key for 1 second or more during All OFF,

Security items
• Forced power-ON mode (all models)
Even when writing is permitted by the security function (mask
key), Power-on can be set for a 30 minute period each time
the reset key is pressed while holding down the ATT key
and Preset 4 keys. After 30 minutes elapses, can only be
restored by using reset.
• How to register the security code for EEPROM (F/E)
replacement (coded security models)
1. While holding the FM key and the preset 6 key, reset the
unit.
2. Call up security register mode by pressing the CLK key.
3. Enter the code with the Preset 1/2/3/4 keys.
For example, to enter the number, "3510"....
- Press the Preset 1 key 4 times.
- Press the Preset 2 key 6 times.
- Press the Preset 3 key 2 times.
- Press the Preset 4 key 1 time.
4. Hold down the DISP key for at least 3 seconds and the
message, "RE-ENTER" appears, so once again enter
the code according to Step 3 above.
5. Hold down the DISP key for at least 3 seconds, and the
message, "APPROVED" appears.
6. Cancel test mode. (See, 2. How to cancel the test mode.)
Note: All clear cannot be performed on the security code
for this model.
• Simple way to clear the security code (K type only)
1. During code request mode, press the VOL UP key for at
least 3 seconds while holding down the DISP key.
(---- will disappear)
2. Enter, "KCAR" with the remote controller as described
below. (Same as on 00 model.)
Press the remote controller 5 key twice, and press the
Track Up key. (Enters a "K")
Press the remote controller 2 key three times, and press
the Track Up key. (Enters a "C")
Press the remote controller 2 key once, and press the
Track Up key. (Enters an "A")
6
ADJUSTMENT
Press the remote controller 7 key twice, and press the
Track Up key. (Enters an "R")
3. Security function is canceled and unit sets to All-Off mode.
4. Code request mode appears if a mistake was made in
entering the numbers.
• Mask key write method on initialized EEPROM
1. While holding the FM key and the preset 6 key, reset the
unit.
2. Press the CLK key to call up mouse key register mode.
The message, "TRANSMIT 1" appears. The display at
this time shows "< >" rather than "[ ]".
3. Face the mask key towards the photosensor and hold
down for half a second or longer.
4. When "TRANSMIT 2" appears, again hold down the mask
key for at least half a second. The first and second counter
codes are not compared at this time.
5. When the message, "APPROVED" appears, the writing
is complete. The demo mode is set at this time and test
mode is canceled.
Note: Just as with the previous model, if 30 minutes elapses
and the code is not written, then an error is issued and
power-OFF is triggered.
• How to initialize the mask key (Return to factory settings
from mask key write permit status.)
1. While holding the FM key and the preset 6 key, reset the
unit.
2. The message, "TRANSMIT 1" appears and mask key
request mode is called up. The display at this time shows
"∗ ∗" rather than "[ ]".
3. Cancel the mask key on the remote control by holding
down for at least 3 seconds.
4. When "TRANSMIT 2" appears, again hold down the mask
key for at least 3 seconds.
5. When the message, "APPROVED" appears, the mask
key is canceled, demo mode is set, test mode is canceled,
and the factory settings restored.
• How to All-Clear the mask key
1. While holding the FM key and the preset 6 key, reset the
unit.
2. Press the CLK key to call up mouse key register mode.
The message, "TRANSMIT 1" appears.
3. Face the mask cancel key towards the photosensor and
hold down for 3 seconds or longer (until level reaches
full).
4. When "TRANSMIT 2" appears, again hold down the mask
key for at least 3 seconds. If "TRANSMIT 1" appears at
this time, then redo the procedure, starting from step 3.
5. When the message, "APPROVED" appears, all-clear has
been performed on the security data and operation returns
to the Mask key write method on initialized EEPROM.
