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.
• Conrm that BaseStation antenna or transceiver are in an appropriate location and orientation.
• Conrm 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 hard wired 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.
• Conrm that the channel is working wirelessly, from the BaseStation to a BeltStation.
• Conrm 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 hard wired 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 hard wired 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 hard wired 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 hard wired 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 hard wired 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 specic headset microphone being used, the audio coming from that microphone may sound
choppy or clip off the rst part of words or sounds.
If the microphone gain is set too high for the specic 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.
