Teaching in the hand transmitter on the operator/
receiver
The hand transmitter works with a rolling code that
changes with each sending procedure. For this reason, the
hand transmitter must be taught in with the desired hand
transmitter button on each receiver that is to be controlled.
1. To do this, briefly press the P button on the operator
cover or the P button on the receiver (see Fig. 3). The
red LED will begin to flash, signalising that the desired
hand transmitter button can be programmed. that the
desired hand transmitter button can be taught in.
2. Press and hold the hand transmitter button until the red
LED flashes quickly; then release the hand transmitter
button.
