This guide covers the initial operation of the Sommer 4026 2-Channel Transmitter. It includes procedures for pairing the transmitter with the receiver, deleting previously learned codes, and configuring the light function.
Learning the radio code
Follow these steps to pair your transmitter with the receiver:

- Press the Learn button (1) on the control housing once. The LED (Radio) will turn solid.
- Press the desired transmitter button (2).
- The LED (Radio) will flash briefly. If the LED lights up for a second, the transmitter has been successfully learned.
You can repeat these steps to program additional transmitters. A maximum of 20 storage locations are available.
Deleting a previously learned radio code
If you need to remove a transmitter from the receiver's memory:
- Press the Learn button (1) on the control housing for at least five seconds until the LED (Radio) blinks slowly.
- Press the desired transmitter button (2).
- When the LED (Radio) turns off, the radio code for this transmitter button has been deleted.
Light function
To switch the light on the opener on or off separately using the transmitter, you must "learn in" a second transmitter button function:

- Press the Learn button (1) on the control housing two times. The LED (Radio) will blink briefly.
- Press the desired transmitter button (2).
- When the LED (Radio) lights up for a second, the transmitter button has been learned for the light function.
Other functions
Depending on the DIP switch settings, other functions such as "partial opening" or "defined operation" can be learned in for a second transmitter button using the same procedure described in the light function section. Refer to the "Settings" chapter in your full manual for more details.
