CANCELLING CODES FROM RADIO CONTROL DEVICES
1_ Keep button CH1 pressed for 3 seconds in order to cancel all the associated radio control devices;
2_ LED DL8 flashes slowly to indicate that the cancellation mode has been activated;
3_ press button CH1 again for 3 seconds;
4_ LED DL8 turns off for approx. 3 seconds and then remains steady to indicate that the code has been
cancelled;
5_ repeat the procedure from point 1 using button CH2 to cancel all the associated radio control devices;
6_ repeat procedure from point 1 using CH1 and CH2 buttons at the same time to erase all transmitters
programmed into the third channel;
7_ to exit the learning mode without memorising a code, press button CH1 or CH2 briefly.
MEMORY CAPACITY
The code memory capacity* of the D749MA-R can be expanded from 86 to 126, 254 or 1022 codes (trans-
mitters) by replacing the memory cards as follows (plug them onto J3 connector, see wiring diagram):
126 codes
254 codes
1022 codes
* Control units are supplied with a standard built-in 86-code memory. The memory card for enhancing the
code memory capacity must be ordered separately.
WARNING: Control unit must be turned OFF to insert / remove a memory card.
IMPORTANT: when a memory card is used, the control unit's built-in 86 codes memory
is disabled.
RADIO MEMORY RESET:
- press without releasing keys CH1 and PROG till LEDs DL7 and DL8 start flashing quickly with a yellow
light. At this point release the keys and press them again till the LEDs go off confirming the operation
is complete (if they are not pressed the board reverts to normal operation after about 12 seconds).
HARD RESET (factory setting):
- press without releasing keys CH2 and PROG till LEDs DL7 and DL8 start flashing quickly with a red
light. At this point release the keys and press them again till the LEDs go off (reset in progress),
confirming the operation is complete (if they are not pressed the board reverts to normal operation
after about 12 seconds); When the unit starts again saving will be required.
In case of Hard Reset the memory of the radio receiver will not be erased: all existing
transmitters remain programmed.
11. MALFUNCTIONS: POSSIBLE CAUSES AND SOLUTION
The automation does not start
a- Check there is 230V AC power supply with the multimeter.
b- Check, in the standard mode, that the NC contacts on the board are really normally closed (4
green LEDs on).
c- Set dip-switch 6 (phototest) OFF.
d- Increase the FR trimmer to the limit.
e- Check that the fuses are intact with the multimeter.
The radio control has very little range
a- Check that the ground and the aerial signal connections have not been inverted.
b- Do not make joints to increase the length of the aerial wire.
c- Do not install the aerial in a low position or behind walls or pillars.
d- Check the state of the radio control batteries.
The automation opens the wrong way
Invert the motor connections on the terminal block (terminals 28 and 29 for M1; terminals 23 and
24 for M2).
