ADJUSTMENT
11. Others � Automatic panel close is disabled when tape or CD is inserted. (M&T model) � Panel operation is disabled at Power-ON or Power-OFF. (M&T model) � 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, calls up the Mask Key (security) write mode. 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.

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�)
