You can temporarily turn Off the microphone so that the person you
are talking with cannot hear you. During a telephone call press and
hold menu/mute to turn Off the microphone, and "
the display. Press menu/mute again to cancel muting.
If you press end to cancel muting, the call is disconnected and the phone
will return to standby mode.

Tone Dialing Switch-over

Some telephone companies use equipment that requires pulse dialing
(sometimes referred to as rotary dialing). If you need to enter tone
dialing digits, you can switch-over to tone dialing during the call.
For example, entering your bank account number after you have
called your bank.
Initially make your call with the pulse dialing mode. Once your call
*
connects, press tone. Enter the desired number. These digits will
be sent as tone dialing. Once the call ends, the tone mode is
canceled and pulse dialing mode resumes.

Traveling Out-of-Range

During a call, as you begin to move your handset too far from your base unit, noise
increases. If you pass the range limits of the base unit, your call will terminate within
30 seconds.
