2.8.4 Confirmation of correct learning/deletion
The output which is toggling every second while in teach-in mode (see above) will stay
switched high for 4 seconds to signal that a transmitter has been learned. In case a trans-
mitter ID has been deleted it will stay 4 seconds low.
2.8.5 Learning of further transmitters
After confirmation, the receiver changes again to readiness for learning. Further transmit-
ters can be learned immediately. If available the next receiver channel can be entered by
connecting the LRN pin to GND longer than t = 0.5 seconds. A maximum of 30 radio
transmitters can be learned (further attempts will be ignored; instead of learning confirma-
tion, operating mode is entered). Each rocker of a radio transmitter is counted as one
transmitter.
2.8.6 Selecting the next channel
By fresh contacting of the LRN pin to GND the next remaining channel is selected. In one-
channel mode or after the last channel, the operating mode is entered again.
2.8.7 Leaving learning mode
LRN mode is left in either one of the following events:
2.8.8 Deleting a transmitter
Deletion of one specific transmitter: Use the same procedure as learning the associated
transmitter.
As transmitter delete confirmation, the corresponding function outputs remain in inactive
state for 4 seconds while LMI keeps active. After that, a wrongly deleted transmitter can be
learned again immediately.
Deletion of all learned transmitters: Connect the CLR pin longer than 2 seconds to GND
All learned transmitters on all channels are deleted at the same time. After this, the re-
ceiver enters Learning Mode.

Output of last available channel is toggling and a fresh contacting of the LRN pin to GND
for 0.5 seconds is performed
No ID has been added/deleted during the last 30 seconds.
Memory was full and another ID was sent to be learnt
Please note that in modes 2, 3, and 4 only RPS or HRC telegrams can be learned!
In order to delete a PTM transmitter the same rocker as during learn has to be
operated. If several rockers of a PTM transmitter have been learned, all have to be
deleted separately.
