• For all models:
Installation of an external aerial
If the aerial supplied is in an unfavourable position and the
radio signal is weak, an external aerial may be installed to
improve reception (mod. ABF or ABFKIT). The new aerial must
be positioned as high as possible and above any metal or
reinforced concrete structures present in the area.
–
Connection to the Control Unit
:
Use a coaxial cable with
an impedance of 50 ohm (for example, a RG58 cable with
low loss).
Caution!
– To reduce signal dispersion use a
cable that is as short as possible (not exceeding 10 m).
–
Connection to the receiver (only for models with univer-
sal type connection):
Open the receiver by first raising the
smaller section of the cover (
fig. 4-a
) and disconnect the
aerial supplied; then connect the cable of the new aerial to
terminal
1
and
2
as follows (
fig. 3

):
Terminal 1
=
sheath
;
Terminal 2
=
core.

Programming warnings
The settings described in this chapter (except for proce-
dure

) require use of the key and led on the receiver (
fig.
6
). To indicate the state of activity in progress, the led
emits a set number of flashes with a specific duration and
colour (green, red or orange). For the meaning of these
signals, refer to
Table A
at the end of the manual.
