I found the manual to be clear concise and complete. It was of immense assistance when removing the unit as the unit was over 22 years old and the wiring diagram was unobtainable from the manufacturer. The exploded drawings were clear as were the instructions and labels.
KRC-791/Y
TEST MODE
• 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. • 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.
