Programming Transmitters (Momentary Working Model):

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

การซ่อมบำรุง

• รักษาเครื่องรับสัญญาณให้สะอาด ปราศจากฝุ่นและความชื้น
• ตรวจสอบการเชื่อมต่อสายไฟทั้งหมดเป็นระยะ เพื่อให้แน่ใจว่าแน่นหนาดีแล้ว
• Ensure the antenna is unobstructed for optimal performance.
• อย่าพยายามเปิดตัวรับสัญญาณasing unless necessary for wiring or programming, and always disconnect power first.

การแก้ไขปัญหา

• เครื่องรับสัญญาณไม่ตอบสนองต่อรีโมท:
  • Check if the receiver is powered correctly (LEDs on the board should be lit).
  • ตรวจสอบให้แน่ใจว่าแบตเตอรี่ของรีโมทคอนโทรลไม่หมด
  • Verify that the remote control has been correctly programmed to the receiver. Try re-programming the remote.
  • If multiple remotes are not working, try erasing all codes and re-programming them.
• 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.

เคล็ดลับสำหรับผู้ใช้

• 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.
