Special display when the display is All ON Pressing the Preset keys while the power is All OFF dis- plays the following information. 7 Security-related information • Forced Power ON mode (All models) Even when the security (Mask key) is approved, reset- ting 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. • 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 "APPROVED" is displayed. 5. Exit from the test mode. (See 2 How to exit from the test mode) (Note) All Clear is not applicable to the security code of this model. • Simplified method of clearing the security code (K Type only) 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. 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) • Pressing the ATT key opens or closes the panel. (M&T model) • Messages such as "CODE OFF" are not displayed when power is turned ON. • 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. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 KRC-709,779R/RY,889 9 TEST MODE • Method of writing the Mask key while the EEP- ROM 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.

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 com- pared 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 min- utes have elapsed with no code written, an error occurs and the power is turned OFF. • Method of initializing the Mask key (How to reset the unit from the Mask key approved condition 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 seconds. 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. • 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 "TRANSMIT2", 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 status. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 KRC-709,779R/RY,889 10 ADJUSTMENT ATTENTION No ITEM INPUT SETTINGS OUTPUT SETTINGS TUNER (RECEIVER) SETTINGS ALIGNMENT POINTS ALIGN FOR FIG.
