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:
Number of green | Network signal strength | |||
light flashes |
| |||
|

|
|
| Unacceptable (no networks) |
|

3 | - - - | - - - | - - - | Very good |

Note: if you have the DA20 accessory display (See “Accessories” on page 39), 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:
Red light | Power supply situation |
FCT power supply is on | |
|
|
Flashing- - - | FCT is powered from battery |
|
|
OFF | FCT power is off (FCT switched off) |
|
|
When both red and green lights are flashing simultaneously, it means that the FCT is under alarm conditions. In this situation, ONLY EMERGENCY CALLS can be made.
Depending on the number of flashes, the table shows the type of alarms that may be happening.
Note: if you have the DA20 accessory display
(See “Accessories” on page 39), the specific alarm status message will show on your display.
