74 Tempest®24 00 4-Channel Wireless Intercom System
Troubleshoo ng
BaseSta on
Limited RF range
BaseSta on antennas or transceiver should be located as high as possible. Loca ng the BaseSta on antennas above
head level is cri cal for op mizing performance and range.
• Con rm that BaseSta on antenna or transceiver are in an appropriate loca on and orienta on.
• Con rm that antennas or transceiver are not close to any metal structures or racks; locate the BaseSta on and
BaseSta on antenna or transceiver away from poten ally interfering devices.
• Ensure that antenna connec 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 mul ple Tempest BaseSta ons in close proximity to each other, Accu-Sync should be used to
achieve maximum performance; in addi on, set the Network Number for each BaseSta 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 ques on. Ensure that the Talk bu 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.
• Con rm that the channel is working wirelessly, from the BaseSta on to a BeltSta on.
• Con 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 Switches on
the front of the BaseSta on are in the appropriate posi 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 connec ons have been properly made on the back
of the BaseSta on.
• If all connec ons are made correctly with all front panel controls properly set, and there is s ll no external
hardwired intercom audio present in the Tempest system, subs 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
BaseSta on.
Headset microphone sounds distorted or cuts off parts of words
If the microphone gain is set too low for the speci c headset microphone being used, the audio coming from that
microphone may sound choppy or clip o the  rst part of words or sounds.
If the microphone gain is set too high for the speci 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 con nuously when
audio is present.
