The SIM gives you three chances to enter the PIN correctly. If the PIN is entered incorrectly three times, the message ‘‘SIM BLOCKD’’ (SIM is blocked) is displayed.

Should this happen, refer to the chapter Problems You Can Solve.

After the PIN has been entered correctly, the phone searches for a GSM network and the message‘‘SEARCHING’’ is displayed.

Once a GSM network has been found, three short beeps are heard and the SERV (Service) indicator comes on in the display. An abbreviation for the GSM network is displayed on the left of the display. You may now make and receive calls.

Signal strength meter

A signal strength meter shows the strength of the received signal, 0 to 5. A value of 5 indicates a strong signal

A battery meter is shown on the right of the display. It starts at 5, after a fully charged battery has been attached to the phone. As the battery loses charge, the battery meter

shows this in steps of 1, until 0 is shown when the battery has no charge left. You can read more about this in the chapter Batteries and Recharging.

Note the following points:

The phone will search for the ‘‘home’’ network. If this is not available, the phone will search for a GSM network from those in range, provided that Automatic Network Selection is chosen.

If Manual Network Selection is chosen, and the ‘‘home’’ network is not available, ‘‘SEL NETW’’ (Select Network) is displayed. Then you have to select a GSM network yourself. You can read more about this in the description of Special Function Nos. 7 and 9 in the chapter Special Functions.

The SERV indicator flashes:

This indicates that a GSM network is in range, but the phone will not register on that network. You can, however, make emergency calls. Refer to the section Emergency Calls, later in this chapter,

The message ‘‘NO NETW’’ (No Net- work) is displayed:

No network is available.The reason may be:

You are in an area which is not covered by a network

The received signal is too weak.Try moving the phone or the car to obtain a stronger signal. Refer to the chapter Problems You Can Solve.
