TROUBLESHOOTING AND FCT INDICATORS
This chapter describes the procedures to identify and, if
possible, correct problems that might occur with the FCT or its
installation. Some problems require that you call your network
operator, but most problems you encounter you can easily
correct yourself.

LIGHT INDICATORS
The FCT has two Light Indicators: red and green.
The
green light
indicates the network signal strength,
according to the following table:

Note: if you have the DA20 display adapter accessory (See
“FCT accessories” on page 41), a “No networks” message
will show on your display when no network is available. If
another network to which your SIM card is locked is available,
the message “Emergency only” will appear instead, indicating
that you will be able to make emergency calls only.
The
red light
indicates the FCT power supply situation:
