Network search
After you have switched on your FCT and entered the
PIN, the FCT automatically searches for a network.
Note: if the red light is off, there is a problem with
the power supply. See “Troubleshooting and FCT
indicators” on page 33.
When a network is found, the green light switches
on or flashes depending on the GSM signal strength.
See Light Indicators on page 33.
Note: if the green light is off, you do not have access
to the GSM network at your present location.
Now you have prepared the FCT for wall installation.
Please, follow the instructions below for complete
wall installation.
Installing the FCT on the wall
FCT Location
The GSM signal strength available at the FCT
location affects the performance of the unit. The
stronger the GSM signal, the better the FCT
performance.
Tip: test several potential locations by moving the
FCT while looking at the green light. Select the
location where the green light is steady, or the
location with the highest amount of flashes.
Note: moving the FCT as little as 20 cm can affect
the GSM reception quality.

Please consider the following recommendations:
• Always select an indoor location, preferably close to
a window and the roof. Generally, you will experience
better GSM signal strength in these places.
• Do not install the FCT in a bathroom, a wet or
damp basement or an outdoor location.
