4.14 Switching off the ring tone
If at any time you do not want to be disturbed, you can turn off the ring tone on the
handset.
Switching off the ring tone
Press and hold the button for 2 seconds. The symbol will appear in the
display. Incoming calls will now only be signalled at the base station and no longer
at the handset.
Switching on the ring tone again
Press and hold the button again for 2 seconds. The symbol in the display
will go off.
4.15 Temporary tone dialling
If you can only use your telephone in Pulse Dialling mode, you do not have to
forego the facilities of Tone Dialling (e.g. interrogating an answering machine). You
can change temporarily to Tone Dialling during a call by means of the (press
the button until you hear a beep) button.
PULSE dialling will be reselected at the end of the call.
4.16 Display illumination
Your telephone is equipped with an automatically illuminated display. The
illumination is automatically switched on when a button is pressed on the mobile
unit.
The illumination then switches off automatically after 10 seconds if no further
buttons are pressed on the mobile unit.
The display illumination also comes on when a call comes in, so that you also get a
visual indication of an incoming call.
