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).
1. Press Menu to enter main menu.
2. Scroll to Settings, and press Select.
3. Scroll to Advanced, and press Select.
4. Scroll to Echo canceller, and press Select.
5. Press Change to select between On or Off.

Canceller (AEC)" on page 126.
