Operating Instructions
Pairing the Remote Control
To ensure proper functionality, the remote control must be paired with your adjustable bed base's control box. Follow these steps carefully:
- Prepare the Bed Base: Unplug the bed base from the power outlet. Wait for 5 seconds, then plug it back in.
- Locate Reset Button: Find the reset coding button on the control box under the bed. This button is often labeled "Learn" or "Reset Coding".
- Initiate Pairing on Remote: On the remote control, simultaneously press and hold the "head up" button and the "foot up" button together for 10 seconds.
- Activate Control Box: While still holding the two buttons on the remote, quickly press and release the reset coding button on the control box. Do not press and hold the control box button.
- Confirm Pairing: You will hear beeps from the control box, indicating that the remote is successfully synced.
Important Note: The pairing process must be completed within 15 seconds of plugging the bed base back in and pressing the reset button. If 15 seconds pass, you must unplug the power again and restart from Step 1. Ensure the indicator light on the control box is on when attempting to pair, as the light will go out if not paired within 15 seconds.

- Power Cycle Bed Base: Unplug the bed base from the wall outlet for 30 seconds, then plug it back in. This can reset the control box.
