Accessibility and Voice quality
Bluetooth uses the frequency of 2.45 GHz. WLan, microwave oven and other
devices that use the same frequency can disturb the use of a Bluetooth headset.
Operation Area
Maximum distance between the headset and the telephone is 10 metres
according to standard 1.2. The communication distance between the handset
and headset may vary considerably due to the environment and disturbances
from other 2.45 GHz equipment. Different headsets can also give different
communication distances.
Out of Range
If a connection cannot be made with the connected Bluetooth headset the call
is transferred automatically to the telephone. If the Bluetooth headset and
the telephone get out of range from each other the connection is temporarily
lost. The connection is automatically established again when a call is made
or received.

Portable Device Manager

It is possible to upgrade software and synchronize parameters in your DT390
cordless phone with the Portable Device Manager (PDM) software. PDM
exists as a Windows version (Desk PDM) and as a System version (CPDM),
and is most often used by system administrators only. Desk PDM can be
used together with the advanced desktop charger. The advanced desktop
charger is connected to the PC with PDM software through the network or USB
connectors at the back of the charger, see Figure 17 on page 133.

For more information on PDM or upgrading of your cordless phone, contact
your system administrator.
