Internal Components and DIP Switches
The receiver features DIP switches for selecting operating modes, a learning button for pairing, and screw terminals for secure wiring connections.

Operating Modes
The receiver supports four operating modes, configurable via the DIP switches. Ensure the receiver is powered off before changing DIP switch settings.

| Mode | DIP Switch 1 | DIP Switch 2 | Description |
|---|---|---|---|
| Momentary | OFF | OFF | Press and hold button: Relay ON. Release button: Relay OFF. |
| Toggle | ON | OFF | Press button: Relay ON. Press the same button again: Relay OFF. |
| Latched | OFF | ON | Press button: Relay ON. Press any other button: All relays OFF. |
| 2CH Momentary + 2CH Toggle | ON | ON | Channels 1 & 2 operate in Momentary mode. Channels 3 & 4 operate in Toggle mode. |
Pairing and Clearing Remote Controls
Pairing a Transmitter
- Ensure the receiver is powered on.
- Press and release the Learning Button on the receiver board. The Learning Indicator LED will light up once.
- Within a few seconds, press any button on the remote control transmitter you wish to pair.
- The Learning Indicator LED on the receiver will flash three times and then turn off, indicating successful pairing.
- Test the remote control to confirm functionality.
Clearing Paired Transmitters
- Ensure the receiver is powered on.
- Press and hold the Learning Button on the receiver board for approximately 5 seconds.
- The Learning Indicator LED will turn ON and then OFF.
- After the LED turns off, release the button. All previously paired remote controls are now cleared.
- Test any previously paired remote; the relay should no longer respond.

Troubleshooting
If you encounter issues with your wireless remote control switch, refer to the following common problems and solutions:
- No response from receiver:
- Check power supply to the receiver (DC 12V-30V). Ensure connections are secure.
- Verify the transmitter battery is not depleted.
- Ensure the transmitter is paired with the receiver. If not, follow the pairing instructions.
- Check for strong RF interference in the environment.
- Intermittent operation:
- Ensure the transmitter is within the effective range (100-500m, line of sight is best). Obstacles like thick walls can reduce range.
- Check for loose wiring connections on both the receiver and the load.
- Verify the DIP switch settings match the desired operating mode.
- Relay clicks but load does not activate:
- Check the wiring to the load. Ensure it is correctly connected to the NO (Normally Open) or NC (Normally Closed) and COM (Common) terminals.
- Verify the load's power supply is active and correctly connected.
- Ensure the load's current draw does not exceed the 10A maximum rating of the relay.
- Learning LED does not light up during pairing:
- Ensure the receiver has power.
- Press the learning button firmly. If the LED still doesn't respond, there might be an issue with the receiver.
Maintenance
The CENTURY AOKE wireless remote control switch is designed for low maintenance. Follow these guidelines to ensure longevity:
- Cleaning: Use a dry, soft cloth to clean the receiver and transmitter. Do not use harsh chemicals or abrasive cleaners.
- Environment: Avoid exposing the device to extreme temperatures, high humidity, or direct water contact.
- Battery Replacement (Transmitter): If the remote control's range decreases or it becomes unresponsive, replace the battery. The transmitter typically uses a 12V 23A battery. To replace, carefully open the transmitter casing (usually by removing screws on the back) and insert a new battery, observing polarity.
- Wiring Inspection: Periodically check all wiring connections for tightness and signs of corrosion or damage.
