Cable cross-section max. 0.5 mm2 For operating the transmitter (TX), use:
- 12-24 V~ / 12-24 V–
- 3 V battery (CR2)
Inserting the battery
3 V battery, type: CR2 BG1, lithium
WARNING:
Risk of explosion due to incorrect battery type There is the risk of explosion if the batteries are replaced with an incorrect battery type.

The LED DL2 flashes slowly 1 ×. - Press the P1 button until the LED DL2 flashes.
The display corresponds to the set channel. Depending on the channel, the display is repeated 4 – 8 ×. During this time the channel can be changed. - Press the P1 button repeatedly until the desired channel is set.
The LED DL2 flashes according to the new set channel. Depending on the channel, the display is repeated 4 – 8 × If the LED DL2 flashes 1 × slowly, the new channel is saved. - Repeat the process on the receiver (RX). Set the same channel as on the transmitter (TX).
NOTE:
If multiple photocell pairs are being used, program a different channel for each photocell pair
