During a call some icons may appear on the display:
indicates call is in progress
indicates you have put a call on hold
indicates there is a new incoming call while a conversation is in progress.
In this case, by pressing

you can put the call in progress on hold and
answer the new incoming call,
or, by pressing

you can go on with the conversation in progress and
reject the new incoming call.
If you have answered the new incoming call, by pressing

you can put the
person you are talking to on hold and return to the conversation with the other
person.
Moreover, if you press the Joystick, you have access to a menu, which allows
you to:
• End call number 1
• End call number 2
• Swap calls, putting one on hold and returning to the other
• Use the number keypad to transmit the DTMF tones
• Connect both calls together (Multiparty)
• Access the main menu, for example, to go to the phone book or to read an
SMS message
If you enable the Multiparty function, the same menu will then allow you, using
the function “Split”, to separate the calls and go on with the two (or more) calls
separately.
DTMF – what it is, its use
The DTMF system (Dual Tone Multi-Frequency) allows you to send tones in
standard frequency used for remote control devices that are able to decode
these tones. This system is used, for example, to control voice mailboxes,
answering machines, telephone cards, etc.
