The U9912-BSW (40992G-02) Wireless Belt Station is a portable wireless communication device
that when used in conjunction with a U9911-BSC (41033G-01) Controller Belt Station or one of
the U9900-series gateways becomes part of a wireless intercom system. Up to five users are
able to communicate with each other when using the U9911-BSC. Up to four users are able to
communicate with each other and also with a two-way radio or other wired intercom system
when using one of the U9900-series gateways. Only one gateway/controller is required per
system. Up to four belt stations can be connected to one controller/gateway.

Figure 1: Overview of Belt Station

The U9912-BSW non-VOX Wireless Belt Station is commonly used where extremely high and
varying noise levels become challenging to a VOX belt station's settings, resulting in unwanted
noise being present in a VOX belt station user's headset and causing him/her to frequently adjust
the VOX setting. VOX belt stations may be desired in more stable and less extreme noise
environments.
