Communication
Communication is defined by the Digital Intercom System and configured by the graphical user
interface. See the Digital Intercom System manual (19549P-31) for more information.
Range
The unimpeded line-of-sight range of a belt station and a gateway should be at least 500 ft
(150m). If you are in an environment with metal or concrete walls, this range could be reduced.
If the belt station enters into a "fringe" reception area, a brief sequence of three beeps will be
heard in the headset. This is to serve as a warning of a possible disconnection if conditions are
not improved. When possible, the user should attempt to regain line-of sight contact with the
gateway. When the belt station travels out of range of the gateway, a voice prompt will indicate
that the connection has been lost. To reconnect, simply move back into range and connection
with the gateway will automatically be reestablished, also noted by a voice prompt.

In some circumstances it may be desired to “purge” the U9120-W4 (EU) of some of its linked belt
stations. Typically purging is not necessary unless there are multiple gateways in the same
vicinity and you wish to remove a belt station from this gateway and link to a different gateway.
A gateway can link up to four belt stations where a belt station can be linked to only one gateway
at a time.
Smart Purge
A smart purge is the purge method employed for the U9120-W4 (EU), in which only unwanted
links are removed from the gateway. When this procedure is complete, only belt stations that
are connected to the gateway remain linked. All other belt station links will have been removed
(see the belt station User Manual for the individual belt station purging procedure when
remaining link purging may be necessary.)
