• Attention! For safety reasons, every button and all button combinations must be deleted.
• 1. Press and hold button (B) for 5 seconds until a LED flashes (any channel).
• 2. Release button (B) - radio receiver is in delete mode.
• 3. Press the hand-held transmitter button whose code should be deleted. (The LED extinguishes. Deletion procedure is ended).
• Repeat steps 1-3 for all buttons and button combinations.

Deleting a Channel from the Radio Receiver

• 1. Press and hold button (B) on the radio receiver.
• - 1x for channel 1 (), LED (D.1) lights.
• - 2x for channel 2 (), LED (D.2) lights.
• - The LED flashes after 5 seconds.
• - The LED lights after another 10 seconds.
• 2. Release button (B) - delete process complete.

Deleting the Radio Receiver Memory

• If a hand-held transmitter is lost, all channels in the radio receiver must be deleted for security reasons. Afterwards, all hand-held transmitters must be reprogrammed.
• 1. Press and hold button (B) on the radio receiver.
• - The LED flashes after 5 seconds.
• - The LED lights after another 10 seconds.
• - After a total of 25 seconds all LEDs light.
• 2. Release button (B) - delete process complete.

Connecting External Antenna

• If reception is inadequate with the radio receiver's internal antenna, an external antenna (article no. 7004) can be connected.
• The antenna cable must not exert any mechanical force on the radio receiver.

Troubleshooting

• LEDs (D.1 and D.2) flashing: An attempt was made to set more than 112 memory slots on the radio receiver.
• LED (D.1 or D.2) flashing: Programming mode, radio receiver is waiting for a radio code from a hand-held transmitter.
