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.

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.
