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 TEL 13942296513 QQ 376315150 892498299 KRC-791/Y 10 ADJUSTMENT No ITEM INPUT SETTINGS OUTPUT SETTINGS TUNER (RECEIVER) SETTINGS ALIGNMENT POINTS ALIGN FOR FIG.
