After applying power to the receiver, wait for about 10 s. The red LED on the
receiver should flash with a short single pulse with a period of 5 s (in the delivered
state).

Press the "F/C" button on the PDU-L - the red LED of the remote
will go in the double's treatment outbreaks (mode is active 8 s).
Send remote control PDU-L to the remote control IR receiver at the detector
receiver and by pressing the corresponding button set the threshold detector
according to the draft (1 dB - button "1", 2 dB - button "2", 3 dB - button "3").
Recommended values the thresholds depending on the working distance are
1 dB at a distance of up to 20 m, 2 dB at a distance of 20 to 40 m, and 3 dB at a
distance of more than 40 m.
If the memory is successfully completed, the red LED should give 3 flashes
with a duration of 1 second every. The detector is ready for operation.
If an error of remembering that may occur if:
- background level exceeds the maximum allowed;
- supply voltage does not correspond to a nominal value;
- the level of interference exceeds the maximum allowed;
- the signal strength is less or more than the allowable value
the red LED should go into the dual flash mode with a repetition period of about
1 s, indicating a malfunction.
It is necessary to eliminate the factors that prevent the memorization -
control distance between the transmitter and receiver and the jumper on the
transmitter in the appropriate position, to ensure absence and obstacles
overlapping their line of sight between the transmitter and receiver or presence
reflective (specular) surfaces near the optical axis between transmitter and
receiver.
After elimination the detected reasons, repeat the memorization with the
desired threshold.
If the memorizing is successful, the detector goes into standby mode, and by
specifying the set threshold for the number of flashes with a period of 5 seconds
(see Table 1).
