When the frequency band is set to "Multifrequency" and the handset is restarted, it adopts
the frequency band (EU, US or Brazil) used in that particular region.
NOTE: The handset adopts the frequency band configured in the DECT system.
The recommended procedure when changing frequency band is as follows:
1 The site administrator transmits a broadcast message to all handsets informing them
that they need to be restarted at a specific time.
2 The site administrator enters IP-DECT master and changes the frequency setting and
carriers just before the specified time.
3 The users all restart their handsets. After the restart the handsets change to the
applicable frequency band or the default 'EU, US or Brazil'.
After the restart the handsets have changed to the applicable frequency band (EU, US or
Brazil).
