Pairing RC4 LumenDim Receivers with CRMX Transmitters

RC4 LumenDim devices must be paired with a compatible transmitter before they can be used wirelessly.  The transmitter must send CRMX or W-DMX data.

RC4 Series 3 dimmers use small recessed pushbuttons that cannot be accidentally pressed when the device is inside a prop, set piece, or costume.  You will need a bent paperclip or other small tool to operate these buttons.

Follow these simple steps:

• Ensure that the transmitter and the LumenDim device are powered on and near each other.
• If the LumenDim was previously paired to a different transmitter, press and hold the recessed RF Connect button on the dimmer for at least 5 seconds. The blue RF Connect indicator should go off (not on, and not blinking).
• Press the Link button on the transmitter (depending on the make and model, this transmitter button might be marked as Function or Connect). An indicator on the transmitter will start flashing.  The blue RF Connect indicator on the LumenDim will also start flashing.
• While indicators are flashing, briefly press (do not hold) the RF Connect button on the LumenDim. When the transmitter stops flashing, the blue RF Connect indicator on the LumenDim will remain lit, indicating that pairing is complete.
• If DMX data is supplied to the W-DMX transmitter, the yellow DMX indicator on the LumenDim will be on.

The LumenDim will remain paired to the same transmitter until it is changed using the same procedure with a different transmitter.  Consult Lumen Radio CRMX documentation, or documentation for the transmitter you are using, for additional information.
