- Page 4 The U9922-G38(EU) provides communication for up to four users as well as an interface to an existing David Clark Model 3800 wired intercom system. Additionally, the U9922-G38(EU) can be used as a stand-alone wireless intercom gateway with two-way radio interface. Up to four belt stations can be connected to one gateway.
