ANTENNA INSTALLATION

To obtain efficient operation the receiver requires a tuned antenna (NICE ABK - ABKIT type). Without
an antenna, the range is reduced by a few metres. The antenna must be installed as high as possible.
If metal frames or reinforced concrete is nearby, install the antenna above them. If the cable supplied
with the antenna is too short, use a coaxial cable with a 52 Ohm impedance (e.g. RG58 with low loss <20
dB for 100m. at 400 MHz). The cable must not exceed 10m. in length. Connect the core to terminal 2 and
the sock to terminal 1 (in the dual position unit). If the antenna is installed where there is no sturdy floor
(building work) the sock terminal can be earthed (grounded) so as to obtain a larger range. Obviously
the earth (ground) plate must be in the immediate vicinity and of high quality. If the ABK - ABKIT tuned
antenna cannot be installed, satisfactory results can be achieved if a section of wire is stretched 2.45 m.
length and connected to terminal 2 to act as an antenna.
LEARNING
Each transmitter has its own code (selected from over 1 million codes) that identifies it from any other
remote control. The receiver is designed to receive all codes, but will only be activated if its own individual
code is stored in the list of 'authorized' codes. A code is entered into the list via a procedure called
'learning' in which the receiver directly recognizes the code. This procedure (or other similar ones) must

be enabled by the operator by pressing a button located on the receiver card.
The various stages of the procedure are displayed by small LED indicator.
This LED will provide different indications depending on the meaning.
LED off: Normal operation
LED on: Time valid for learning procedure (approx. 5 sec.)
1 flash : Received code is not authorized
2 flashes*: Timeout out on learning without result
3 flashes: Learning completed with positive result
4 flashes: Code already in authorized code list
!
5 flashes: Code list is empty
6 flashes: Code list is full up (no room left for new codes)
7 flashes: Cancellation requested for code not in list
8 flashes: Different codes were received in learning stage
9 flashes: Password entered.
*If the second type of lock is enabled, the 2nd flash will be longer the first.
If the second type of lock is disabled, both flashes will be equally long.
