Alarm Sensor.
Loud environment
If the handset is mainly used in a loud environment, the handset attempts to improve the
voice transmission (does not apply to connections made with the Bluetooth headset and in
hands-free mode).
Audio quality (Aastra 650c only)
This menu entry is only available if your system supports Hi-Q audio.
If the handset is used in reflection-prone environments (e.g. metallic workshops), then interference
to the DECT reception may occur. Aastra XQ technology can be used in these areas in order to pre-
vent this interference. However, Hi-Q audio and the XQ mode influence one another. The following
settings can be used to prevent connection failures in XQ areas.
Standard audio Set this (normal) speech quality if interference may occur (e.g. in XQ
areas).
Hi-Q audio
Attempts are always made to establish a connection in high speech
quality (Hi-Q audio). In the event of an existing Hi-Q connection in a
XQ area where high speech quality is also supported, then this
quality level is maintained. This is the standard setting.
Automatic
Attempts are always made to establish a connection in high speech
quality. If the device is located in a XQ-protected environment, then
incoming or outgoing connections are made in standard speech
quality. Switch on this mode if you switch regularly between areas
(XQ / office) and still wish to use Hi-Q audio in the office.
