BaseStation and/or Remote Transceiver

System range and performance may be greatly reduced if antennas are blocked

or obstructed.

Always operate the system with antenna attached, locate as high as possible
and away from all obstructions (especially metal).

Never use antenna on the back of the BaseStation when the BaseStation is
in a rack

●

When using the Whip (omni-directional) antenna, always locate it as close as
possible to the center of the coverage area.

●

When remotely locating antenna, use only high quality 50 ohm, low loss, RF
cable (30 ft max).

●

Remote antenna location of up to 1500 ft using standard CAT-5 wiring may be
achieved using the optional Tempest Remote Transceiver.

Changing the Default RF

Configuration

Tempest 900 operates in the 902 to 928 MHz frequency spectrum.

Tempest 900 MHz models should never be synced with 2.4 GHz models.

Tempest BaseStations and BeltStations are shipped with a default RF
configuration. It is highly recommended that you change your system from
the default to ensure proper RF performance especially in the presence of
other Tempest systems.

A BeltStation must be paired with a BaseStation for any communication to
take place. Pairing should be done AFTER the default RF configuration is
changed on the BaseStation.

Charge the BeltStation batteries prior to starting set-up.
