20 Tempest®900 2-Channel Wireless Intercom System
6- CALL Button
The CALL Button sends a 2-Wire compatible call signal to any wireless BeltStation and any hardwired intercom device on
the intercom channel. The Call signal will be routed to intercom channels indicated by the user’s active Talk button(s).
1- Rubberized Access Cover
The Rubberized Access Cover helps prevent dust, dirt and liquid from entering the BeltStation
through the USB or the BeltStation pairing connector. Keep this cover securely closed at all times
to ensure the best possible seal.
2- USB Mini B Connector
The USB Connector is used to charge the BeltStation with the supplied wall charger. In addition,
the USB connect is used to update the firmware of the BeltStation.
3- BeltStation Pairing Connector
The BeltStation Pairing Connector is used to pair the BeltStation with BaseStations using the
supplied 1/8” stereo mini connector.
1- Belt Clip
The Belt Clip enables the BeltStation to be worn on the user’s belt or other clothing
item.
2- Power ON/OFF Button
The Power ON/OFF button is used to turn the BeltStation ON or OFF. Press and
hold the Power ON/OFF button for two seconds to turn the BeltStation ON. Press
for four seconds to turn the BeltStation OFF.
3- Battery Compartment
The Battery Compartment holds either one Tempest Lithium-Polymer rechargeable battery or (3) standard alkaline AA
cells. To remove the battery door, press down on the thumb markings and pull the battery door toward the bottom of the
BeltStation. To remove batteries from the battery compartment turn the BeltStation battery side down and tap the bottom
of the BeltStation on the palm of your other hand. Please be careful to insert alkaline AA batteries according to the marked
polarity. All of the alkaline AA cells face the same direction. If the battery cover does not fit or close properly, the battery
may not be inserted correctly.
4- Headset Connector
The 4-pin XLR male headset connector mates with most Dynamic or Electret headsets that have 4-pin XLR female connectors.
This Headset connector allows a user to communicate in “Dual-listen” or “Single-listen” mode on either intercom channel.
The mic detect circuit (dynamic/electret) will indicate dynamic when it sees a load of 600Ω or less. It will indicate an
electret when it sees 1kΩ or greater. Between 600Ω and 1kΩ is not recommended as it may not accurately detect mic type.
If you are using dynamic mics, you should short the input to ground. If you are using electret mics you should open the
circuit. This will keep the belt from switching back and forth between modes.
