74 Tempest®24 00 2 -Channel Wireless Intercom System
Troubleshooti ng
BaseStati on
Limited RF range
BaseStati on antenna or transceiver should be located as high as possible. Locati ng the BaseStati on antenna above
head level is criti cal for opti mizing performance and range.
• Confi rm that BaseStati on antenna or transceiver are in an appropriate locati on and orientati on.
• Confi rm that antenna or transceiver are not close to any metal structures or racks; locate the BaseStati on and
BaseStati on antenna or transceiver away from potenti ally interfering devices.
• Ensure that antenna connecti ons 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 multi ple Tempest BaseStati ons in close proximity to each other, Accu-Sync should be used to
achieve maximum performance; in additi on, set the Network Number for each BaseStati on 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 questi on. Ensure that the Talk butt on 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.
• Confi rm that the channel is working wirelessly, from the BaseStati on to a BeltStati on.
• Confi rm 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 BaseStati on is in the appropriate positi on 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 connecti ons have been properly made on the back
of the BaseStati on.
• If all connecti ons are made correctly with all front panel controls properly set, and there is sti ll no external
hardwired intercom audio present in the Tempest system, substi tute 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
BaseStati on.
Headset microphone sounds distorted or cuts off parts of words
If the microphone gain is set too low for the specifi c headset microphone being used, the audio coming from that
microphone may sound choppy or clip off the fi rst part of words or sounds.
If the microphone gain is set too high for the specifi c 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 conti nuously when
audio is present.
