The SIM memory is full when the 

message symbol flashes. No more 

SMS messages can be received. 

Delete or save messages (p. 32).

A fully charged battery provides 

60 to 300 hours of standby time or 

90 to 360 minutes of talk time. The 

standby times/talk times are average 

values and depend on the operating 

conditions (see table): 

If the phone is exposed to heat the 

standby time is considerably re-

duced. Avoid exposing the phone 

to direct sunlight or placing it on a 

radiator.

If you are outside your "home net-

work" your phone automatically di-

als a different GSM network (p. 52).

You can enter your "own numbers" 

in the Phonebook (e.g. fax) for infor-

mation. These numbers can be 

changed or deleted and also sent as 

an SMS.

If you enter a number with the key-

pad during a call, the person on the 

other end of the line can hear the 

numbers being entered. It can be 

stored or dialled after the current call 

has ended.

Numbers 

 in the message 

can be dialled (press 

A

) or they can 

be stored in the Phonebook (p. 22).
