4.3 Keys and Buttons
4.3.1 Navigation Keys/Selection Key
Use this key when navigating in menus, and to move the cursor when writing some text or a number. The
navigation keys are used for stepping left/right and up/down when navigating in the menus. When
selecting or entering a menu use the selection key in the middle of the navigation keys.
4.3.2 Softkeys
The handset has three softkeys located just beneath the display, and the function of these
is indicated by text on the display just above each softkey according to the respective screen.
4.3.4 Speaker Key
The speaker key is used to shift between speaker mode and normal mode during call. When the handset is
set to speaker mode during call the speaker key lights up in red, and the sound comes from the speaker on the
back of the handset.
4.3.5 Activity Menu Key
When using this key from idle the activity menu is opened from which all the different menus available
on the handset can be opened.
4.3.6 Off-hook Key
This key is used for answering an incoming call, or dialing a number either directly from the idle, or from
the contact list, call list, or central directory. Pressing this key in idle opens the call list.
4.3.7 On-hook, and On/Off Key
The On-hook key is used for disconnecting calls and returning to the previous menus when navigating in
any menu. A long-press in idle will switch the handset off, and a long-press when the handset is switched off will
switch the handset on.
4.3.8 Speed Dial Keys
Any key from “2” – “9” can be set as a speed dial key. A long press on any of these numbers when the handset is
in idle can be set to a short cut to calling any contact in the contact list, or in the F-Key list. For additional
information on this feature see 7.1.4 Speed Dial/On Touch Dial.
4.3.9 Volume Button
These two volume buttons placed on the upper left side of the handset are used for increasing/decreasing the
volume during a call.
NOTE: These buttons are used to control the volume when using the earpiece, a headset, and the loudspeaker,
and the lowest volume will not mute the handset.
