5. Scroll to the desired option, and press Change. You can choose Vibrate in
connection with one of the other options.
DECT Security
You can monitor the DECT system security state if encryption is enabled on the server. It is
only if encryption is enabled, that you can monitor if system security state has changed
(encryption being disabled). A notification is shown in the display.
Note:
If the system security state changes during a call, the ongoing call will still be encrypted.
The subsequent calls will not be encrypted and will end after 15 sec if the handset is not
power cycled. Further power cycles will ensure the handset can only make unencrypted
calls until encryption is enabled on the server again. Contact your system administrator
for more information.
To Monitor System Security State
1. Press Menu to enter main menu.
2. Scroll to Settings, and press Select.
3. Scroll to Advanced, and press Select.
4. Scroll to DECT security, and press Select.
5. Press Change to select between On or Off.
Echo Canceller
You can enable echo cancellation to prevent the far-end user from hearing echo. Enabling
echo cancelling does not prevent you from hearing echo. Echo cancelling is only applied to
the ear speaker; therefore, it cannot be used when the speakerphone is on. If you start using
echo cancellation on a site (e.g. manufacturing industry verticals), then it is highly
recommended, that echo cancellation is enabled on all handsets.
Note:
If echo cancellation is enabled, settings under Noisy environment are overruled. If
none of them are enabled, soft talk shift function is used.
Note:
Normally, the ear speaker volume has 8 steps (except when using HAC, that only allows
use of step 3-8). If enabling echo cancellation, it is possible to increase the volume with
2 extra steps (1 – 10).
