4.3 Pairing with RTS Motorized Devices
To synchronize the wall control with your RTS motor or receiver:
- Locate the 'PROG' button on your RTS motor or radio receiver.
- Press the 'PROG' button on the motor/receiver briefly. The motor/receiver will enter programming mode (refer to your motor/receiver's specific manual for visual confirmation, e.g., a light flash or slight movement).
- Within 10 seconds, press any button on the Somfy 1870781 wall control.
- The motor/receiver will confirm successful pairing (e.g., a second light flash or movement).
- Repeat this process for each of the three buttons if you wish to control three separate devices.

5. Operating Instructions
Once paired, operating your motorized devices is simple:
- Each of the three buttons on the wall control corresponds to a specific paired device.
- Press the assigned button once to activate the associated device (e.g., open/close a gate, raise/lower a garage door, turn on/off lights).
- For devices with intermediate positions (like rolling shutters), a second press might stop the movement, and a third press might reverse it. Refer to your specific motor's operating instructions for detailed control sequences.

6. Maintenance
6.1 Battery Replacement
The Somfy 1870781 wall control is powered by a 3V CR2430 Lithium battery. When the battery level is low, the control's indicator light (if present) may dim or fail to illuminate, or the range of the signal may decrease. To replace the battery:

6.2 Cleaning
Clean the surface of the wall control with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the unit's finish or internal components.
7. Troubleshooting
- Device not responding:
- Check if the battery in the wall control needs replacement.
- Ensure the wall control is within the operating range of the RTS receiver.
- Verify that the wall control is correctly paired with the motorized device. If not, repeat the pairing process (Section 4.3).
- Check the power supply to the motorized device.
- Intermittent operation:
- Replace the battery in the wall control.
- Ensure there are no significant obstructions (e.g., thick walls, large metal objects) between the wall control and the receiver that could interfere with the radio signal.
