How do I change the keypad code on my LDO/LSO/LCO operator with serial number after 20100915XXXXX?
If you don’t know the current code, you must erase the memory in the operator. Press and hold the "Learn" button for 10 seconds or more. When you release the "Learn" button, the red LED above the button will blink 3 times and then come on bright for 15 seconds. When the LED goes out, the memory in the operator is erased. To learn in a new keypad code, press and release the "Learn" button. The LED will come on for 15 seconds. While the LED is on, go to your keypad and enter your desired code (1 to 6 digits long) and press start/stop on the keypad. The LED will blink to indicate receipt of the new code. You will also have to reenter all of your hand held remotes into the memory. Again, simply press and release the "Learn" button. When the LED comes on, press the button on the remote you wish to use. Repeat for any additional remotes. If you hold the "Learn" button down for 10 seconds or more, you will have to start over, since the memory will be erased again.
