Setup
- Connect Power: Plug the USB male connector of the ZABLL P30 receiver into a 5V USB power source (e.g., USB wall adapter, power bank, computer USB port).
- Connect Device: Plug your USB-powered device (e.g., LED light, fan) into the USB female connector of the ZABLL P30 receiver.
- Initial State: The receiver and transmitter are pre-paired at the factory. Upon initial connection, the device connected to the receiver will typically be in the OFF state.
Operating Instructions
The ZABLL P30 operates in a latched mode. This means one button turns the device ON, and another button turns it OFF.
- To Turn ON: Press button 'A' on the remote control. The indicator light on the receiver will illuminate, and the connected device will power on.
- To Turn OFF: Press button 'B' on the remote control. The indicator light on the receiver will turn off, and the connected device will power off.
The RF signal allows control from a distance of 20-50 meters, even through walls, floors, and doors, provided there are no significant signal obstructions.
Code Pairing (Learning Function)
The receiver has a learning function, allowing it to be paired with additional remote controls or to re-pair with the original transmitter if needed. Specific instructions for entering learning mode are not provided in the product description, but typically involve pressing a button on the receiver for a few seconds until an indicator light changes, then pressing a button on the remote.
Applications
This wireless remote control switch is suitable for a wide range of 5V USB-powered devices, including but not limited to:

Troubleshooting
- Device not turning ON/OFF:
- Ensure the USB receiver is properly connected to a 5V power source.
- Verify the USB-powered device is correctly plugged into the receiver's female port.
- Check the remote control transmitter's battery. The transmitter uses DC 6V (likely two CR2016 or similar batteries).
- Confirm you are within the effective range (20-50 meters) and there are no excessive obstructions.
- If the receiver's indicator light does not respond, try re-pairing the remote control (refer to Code Pairing section).
- Intermittent control:
- Reduce the distance between the transmitter and receiver.
- Minimize physical obstructions between the remote and receiver.
- Replace the remote control battery.
- No data transfer:
- This device is designed for power control only and does not support USB data transfer.
Maintenance
- Keep the device and remote control dry and away from moisture.
- Avoid exposing the device to extreme temperatures.
- Clean with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Replace the remote control battery when its performance degrades.
