Pairing your Richmat HJC18 control box with the HJH37 remote involves a specific sequence of steps. While direct instructions for the HJH37 remote are limited, similar Richmat models follow comparable procedures. Here’s a general guide to assist you:

1. Power Cycle the Devices:
   • Control Box: Disconnect the power supply and, if applicable, the battery pack from the control box. Wait for at least 30 seconds to ensure all residual power is drained. Reconnect the power supply and battery pack.
   • Remote Control: Remove the batteries from the remote. Press any button to discharge any remaining power. After about 20 seconds, insert fresh batteries into the remote.
2. Initiate Pairing Mode:
   • Control Box: Locate the pairing or reset button on the control box, typically found under the bed. Press and hold this button; you may hear a click or beep indicating it’s in pairing mode.
   • Remote Control: Simultaneously press and hold the “Head Down” and “Foot Up” buttons on the remote. Continue holding both the control box button and the remote buttons for approximately 3-5 seconds until you hear three beeps, signaling a successful pairing.
3. Test the Connection:
   • After pairing, test the remote by adjusting the bed’s positions to confirm functionality.

Additional Tips:

• Alternative Button Combinations: If the above method doesn’t work, try holding different combinations on the remote, such as “Head Up” + “Foot Down,” “Head Up” + “Foot Up,” or both in the down position, each for about 10 seconds before attempting the pairing process again.
• Consult the Manual: Refer to the user manual for model-specific instructions.
• Contact Support: If issues persist, consider reaching out to Richmat’s customer support or the retailer for further assistance.
