Problems You Can Solve
Phone Does Not Come On
Recharge or replace the battery. Refer to the chapter
Batteries and Recharging .
If the phone is powered from a cigarette lighter receptacle,
using the
Vehicle Power Adaptor , check that this is
properly connected both to the cigarette lighter receptacle
and to the receptacle at the bottom of the phone. Refer to
the chapter
Accessories .
Note that some vehicles disable the cigarette lighter when
the ignition is turned off.
INSERT SIM Is Displayed
Insert your SIM. Refer to the instructions in the section
Inserting the SIM at the end of this chapter.
The SERV Indicator Does Not Come On
or the Message
NO NETW (No Network) Is Displayed
The phone has not registered on a GSM network and you
cannot make or receive any calls. The reason for this is
either:
The received signal is too weak. See the next section,
Received Signal Is Weak.
You are in an area which is not covered by a GSM network.
The SERV Indicator Flashes
A GSM network is in range but the phone will not register
on it. Emergency calls (
112 ) can, however, be made.
Received Signal Is Weak
Move the phone or the car and observe the signal strength
reading in the display. The maximum reading is
5 .
The strength of the received signal varies from place to
place, and often you need only move the phone by as little
as 20 -- 25 centimeters to obtain a stronger signal.
Large obstacles such as buildings, hills and mountains can
drastically affect the signal strength and you may have to
move to obtain a sufficiently strong signal.
Indoors, it is usually best to use the phone near a window.
If you use an external antenna, check its connection.
Flashing Red Indicator Light -- Alarm
Signal Sounds
‘‘LOW BATT’’ flashes in the display, indicating that the
battery is becoming exhausted. Refer to the chapter
Batteries and Recharging .
