operate simultaneously while in Operational mode. When in Menu mode, ENTER only functions
as an Enter button.
From the Base Station:
To enable the Relay: Select the numbered key 1 through 5 that corresponds to the beltstation
desired. Select “Select Relay”. Select one of the relays: “Relay 1” thru “Relay 5”.
To select a Relay button: Select the numbered key 1 through 5 that corresponds to the
beltstation desired.
Select “7 - Relay Button;” select a button.
Since every user will be require a custom application, cables for your RELAY connections will
require some bench work with a soldering iron.
Use the Transceiver
Choose an optimum location for the Tempest Remote Transceiver and antennas.
Using standard CAT5 cable, connect the Transceiver to the base station RJ-45 connector labeled
TRANSCEIVER.
The “Power” LED on the Transceiver will light if the base station is powering the unit. If the “Power” LED
does not illuminate when connections are made and the base station is on, the Cat-5 cable may be too
long to deliver adequate power to the Transceiver.
Trouble Shooting
Base Station
Limited RF range
Base station antennas should be located as high as possible. Locating the base station antenna(s) above
head level is critical for optimizing performance and range.
Both antennas must be connected.
Confirm that base station antennas are in an appropriate location and orientation.
Confirm that antennas are not close to any metal structures or racks.
Locate the base station and base station antennas away from potentially interfering devices.
Ensure that antenna connections are securely made. If using coaxial cable to remotely locate antennas,
the cable must be a low loss 50 ohm coax, not more than 25 feet long.
If you are using multiple Tempest base stations in close proximity to each other, Accu-Sync should be
used to achieve maximum performance.
Cannot hear one or more channels of hardwired intercom
Set the Front panel headset to monitor the intercom channel in question. Ensure that the Talk button is
enabled for the front panel headset. Turn the headset volume up to a comfortable listening level to hear
your own voice in your headset.
Confirm that the channel is working wirelessly, from the base station to a beltstation.
Confirm that the wired system is working correctly, separately from the Tempest Wireless system.
If using a 2-Wire external wired intercom system, make sure that the 2-Wire Intercom Type Select
Switches A/B & C/D on the front of the base station are in the appropriate position for the type of
hardwired system you are using.
Ensure that the correct 2-Wire or 4-Wire LED is lit for the intercom channel that you are using. If neither
the 2-Wire nor the 4-Wire LED is lit, or if the wrong LED is lit for the hardwired intercom type you wish to
use, no external intercom audio will be present.
Adjust the IN and OUT level for the appropriate intercom channel to achieve the desired audio levels.
Ensure that all external 2-Wire or 4-Wire hardwired intercom connections have been properly made on
Local base station whip antennas are disabled when the remote transceiver is connected.
