Instruccions de funcionament

Programming Transmitters (Momentary Working Model):

This receiver supports learning codes from various transmitters. You can either replace an old remote or add new ones.

Image: Illustration of replacing old remotes or adding new ones.

1. Learning a Transmitter's Code:
   • Press the "LEARN1" (for Channel 1) or "LEARN2" (for Channel 2) button on the receiver board for approximately 1 second. The "learn_led" light on the board will illuminate.
   • While the "learn_led" is lit, press the desired button on your remote control transmitter.
   • Continue pressing the transmitter button until the "learn_led" flashes and then goes out. This indicates that the transmitter's code has been successfully stored.
   • Repeat these steps for any other transmitters you wish to program.
2. Erasing All Transmitter Codes:
   • Press and hold either the "LEARN1" or "LEARN2" button on the receiver board.
   • Keep holding the button until the "learn_led" light illuminates and then goes out. This action will erase all previously stored transmitter codes from the receiver.

• Poor reception range:
  • Ensure the receiver's antenna is fully extended and not obstructed by metal objects or walls.
  • Relocate the receiver to a position with better line-of-sight to where the remote will be used.
• Device not activating/deactivating:
  • Check the wiring connections between the receiver's relay outputs (CH1, CH2) and your device's control inputs.
  • Ensure your device (motor, light, etc.) is functioning correctly independently of the receiver.

Consells per a l'usuari

• For optimal performance, ensure the receiver is installed in a location protected from direct weather exposure.
• When programming, keep the remote control close to the receiver to ensure a strong signal during the learning process.
• If you are replacing an old receiver, make sure to clear all old codes from the new receiver before programming your existing remotes.
