During a Call 25
To use telephone banking services or control a telephone answering machine,
you need to use codes. These codes are sent as tone signals (also known as
DTMF tones or touch tones).
To send tone signals/codes during a call
Press the appropriate keys (09, * and #).
Tip! You can also save the code together with a number in the Phone Book.
See Your Personal Phone Book on page 33.
Note! If you send tone signals while on the phone, the person on the other end
of the line hears the tones.
During a call, the display shows the duration of the call in minutes and sec-
onds. If you prefer, you can have the call cost displayed, provided your net-
work and your SIM card support this feature. See Knowing the Call Time/
Call Cost on page 78 for more information.
Your phone is capable of handling more than one call simultaneously. You can
put the current call on hold, and then make or answer a second call. You can
also set up a conference call with up to five people. See Handling More than
One Call Simultaneously on page 74 on how to use this feature.
