Operation Area
Maximum distance between the headset and the phone is 10 metres.
The communication distance between the phone and headset may vary
considerably due to the environment and disturbances from other 2.45
GHz equipment. Different headsets can also give different communica-
tion distances.
Out of Range
If a connection cannot be made with the selected Bluetooth headset the
call is transferred automatically to the phone. If the Bluetooth headset
and the phone get out of range from each other the connection is tempo-
rarily lost. Since the last connected headset is always considered
“selected”, the connection is automatically established again when a call
is made or received.
20.5 WinPDM and CPDM
Software and parameters in the cordless phone can be upgraded by
using the WinPDM or the CPDM. This is most often only done by system
administrators. The following are examples of additional features that
can be downloaded or configured through PDM:
• Call services
• Company phonebook
• Downloadable language
• Customizing the menu structure
WinPDM is used together with the Desk PDM charger. The Desk PDM
charger is connected to the PC with WinPDM software through the
network or USB connectors at the back of the charger, see figure 21 on
page 119.
