68 Tempest®900 2-Channel Wireless Intercom System
Troubleshooting
BaseStation
Limited RF range
BaseStation antenna or transceiver should be located as high as possible. Locating the BaseStation antenna above
head level is critical for optimizing performance and range.
• Confirm that BaseStation antenna or transceiver are in an appropriate location and orientation.
• Confirm that antenna or transceiver are not close to any metal structures or racks; locate the BaseStation and
BaseStation antenna or transceiver 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 BaseStations in close proximity to each other, Accu-Sync should be used to
achieve maximum performance; in addition, set the Network Number for each BaseStation at least four numbers
apart.
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 BaseStation 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 Switch on the
front of the BaseStation is 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 the back
of the BaseStation.
• If all connections are made correctly with all front panel controls properly set, and there is still no external
hardwired intercom audio present in the Tempest system, substitute another cable (3-pin XLR for 2-Wire or RJ-45
for 4-Wire) making sure that it is connected properly to both the external hardwired system and the Tempest
BaseStation.
Headset microphone sounds distorted or cuts off parts of words
If the microphone gain is set too low for the specific headset microphone being used, the audio coming from that
microphone may sound choppy or clip off the first part of words or sounds.
If the microphone gain is set too high for the specific headset microphone being used, the audio coming from that
microphone may sound distorted at higher audio levels. In this case the peak LED will light almost continuously when
audio is present.
