5.2 SENDING DTMF TONES DURING OUTGOING CALL
Sending DTMF tones is possible during the outgoing call state. In this case, presses on
results in sending DTMF tones to the remote user. No display is done for such entries. The DTMF tone
corresponding to the key pressed is played in the ear-piece as feedback.
5.1.2 ERROR CASES
In each case of error, a warning tone signals the problem and at the same time, an information screen is displayed
during 3 seconds. A press on any softkey allows exiting the screen.
5.1.2.1 E
RRORS DUE TO LOCAL PROBLEMS
The phone may reject the call in the following cases:
♦
When the call is refused due to fixed dialling mode (Error message "Fixed Dialling only"),
♦
Two calls are already connected: a third one cannot be set-up (Error message "Not allowed"),
♦
The SIM has a limited amount of charge and the limit is already reached, so the new call cannot be
set-up (Error message "Max cost reached"),
♦
The phone number structure is unrecognised or is incorrect (Error message "Entry Error"),
In these cases, an information screen is displayed immediately, indicating the reason of the problem and the
display returns to Idle screen or Call connected screen, as appropriate. An example of such a screen is displayed
below.
