4.7.1 Multiple Frequency Support

The handset can be used in a system that changes frequency by selecting

‚"Multifrequency” as frequency band in the handset. See 4.7 DECT Frequency Band

Configuration. This setting is applicable for handsets used in different regions of the

world. For example for users working on a ship that visits different countries.

When the frequency band is set to “Multifrequency”, the handset will adopt to the

applicable frequency band (EU, US or Brazil) used in the specific region after it has

been restarted.

NOTE: The handset will adopt to the frequency band configured in the DECT system.

The recommended procedure when changing frequency band is as follows:

1 The site administrator sends out broadcast message to all handsets informing

that the handsets need to be restarted at a specific time.

2 The site administrator enters IP-DECT master and change setting for the

frequency and carriers just before the specific time.

3 All handset users restart their handsets.

After the restart the handsets have changed to the applicable frequency band (EU, US

or Brazil).
