Alert Tones & Volume
To help distinguish between incoming video calls and ordinary telephone calls, different ringing tones may be
selected. You may also select different volume levels for the ringing tone.
Alert Speaker
The system also has an internal, call alerting speaker.
On
: The internal speaker will warn you of an incoming call even though the monitor may not be switched on.
Key Tones
The Key Tones may be switched on and off.
Restore Audio Defaults
There are many audio settings and the codec could easily be made unusable by configuring these by mistake. It
is therefore possible to return all audio settings to their factory default settings by using Restore Audio Defaults.
• The echo canceller tries to estimate the echo path from the speaker system to the microphones. Moving objects
change this path, therefore try to avoid moving objects. Be especially aware of large objects and objects placed
close to either the microphone or the speaker system as these objects will cause severe changes to the echo
path.
• Avoid putting paper sheets etc. on the microphone.
• Avoid moving the microphone or loudspeaker.
• In the event of poor echo cancelling, allow the canceller to adapt. After each change, the echo canceller
requires a few seconds to adapt. Do not change the settings without allowing the echo canceller to adapt to
the new audio environment.
• In the presence of low frequency noise, enable the noise reduction (NR).
