Range
The range of a belt station and a gateway can be up to 300 ft (100m). 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 light-of sight contact with the controller. When the
belt station travels out of range of the gateway, a voice alert 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 alert.

In some circumstances it may be necessary to “purge” the U9921-GUV 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 six 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 U9921-GUV, 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.)
Smart Purge procedure
1.
Ensure the gateway is powered on and functioning.
2.
Disconnect all belt stations to be purged (power off the belt stations).
3.
Verify the number of green LED flashes on the gateway matches the number of
belt stations to be kept linked.
4.
Press and hold LINK button on the gateway for 30 seconds until LED quickly
flashes red.
5.
Release LINK button.
