In-call options (Menu 9)
The phone interface provides a number of control 
functions that you can use during a call. To ac-
cess the in-call options during a call, simply press 
and hold the Menu for a second. The in-call op-
tions are not numbered. You cannot, therefore, 
access them by the shortcut method.
Mute / Unmute — Switches off or on the commu-
nicator’s microphone. If the communicator is 
connected to a hands free car kit, Mute turns off 
the microphone of the car kit, as well.
Hold / Unhold — Hold allows you to put a cur-
rently active call on hold, so that another call can 
be initiated. After you have finished the new call 
(with Drop call, see below), the original call can 
be made active again by selecting Unhold. If the 
held call is the only call, you can also unhold it 
by pressing 
.
Swap — This function is available when you have 
one active and one held call. Swap makes the held 
call active and puts the currently active call on 
hold. In this way, you may converse with one party 
without ending the other call. Instead of using this 
function, you can press 
to swap between the
calls if no numbers have been keyed in.
Drop call — Ends the currently active call. This 
function is useful when there is an active call, as 
well as a held call. In such a situation, pressing 
would terminate both calls.
Join / Private — Join includes a new participant in 
a conference call. During a conference call, Pri-
vate allows you to converse privately with a se-
lected call participant.
Transfer — The voice call transfer enables you to 
connect two voice calls together and disconnect 
yourself from both calls. See chapter 4 "Tele-
phone: Managing calls - Voice call transfer" on 
page 4-4.
Data — When you have an alternating call active, 
this option changes the mode of the call from 
voice to fax or data (see chapter 4 "Telephone: 
Managing calls - Alternating calls" on page 4-5).
Speech — When you have an alternating call ac-
tive, this option changes the mode of the call 
from fax or data to voice.
Send DTMF — Transmits Dual Tone Multi Fre-
quency tones. This function helps you communi-
cate with answering machines, computerised 
telephony systems, etc. For more details, see 
”Sending DTMF tones” on page 13-3.
