Front Panel Le
1- Local Headset Connector
The 4-PIN XLR male headset connector is compa ble with most Dynamic or Electret headsets that have 4-PIN XLR
female connectors. This headset connector allows a user to communicate on any one of the four intercom channels.
Controls for this connector are located to the immediate right. The mic gain for the Local Headset can be adjusted
from the “Set Mic Gain” menu, under the “BaseSta on Se ngs.”
(Note: the headset must be purchased separately.)
2- Talk Bu on and LED
The Talk bu on works in conjunc on with the Local Headset Connector. The Talk bu on enables or disables the
microphone for the local headset. A blue “TALK” LED will illuminate when the mic is enabled. Tempest uses an
intelligent latching method for talk bu ons. Pressing TALK momentarily will cause the mic bu on to latch. The blue
“TALK” LED will stay lit and the microphone will remain enabled. Pressing and holding TALK will cause the bu on to
act in a momentary fashion. The blue “TALK” LED will remain lit and the microphone will remain enabled only as long
as the bu on is pressed.
3- Call Bu on
The Call bu on sends a wired intercom-compa ble call signal to any wireless BeltSta on and any 2-Wire hardwired
intercom device on the intercom channel currently selected for the Local Headset.
4- Mic Kill Bu on
The Mic Kill bu on sends a signal to wireless BeltSta ons that disables Talk bu ons that are enabled. This bu on is for
the wireless system only. No Mic Kill signal is sent out to the hardwired intercom. Mic Kill signals from the hardwired
intercom are accepted and passed through to the wireless users.
A momentary press and release of the MIC KILL disables any wireless BeltSta on Talk bu on currently enabled on
the selected channel, as well as the BaseSta on local headset connector. If the Mic Kill bu on is pressed and held
for three seconds, all wireless BeltSta on Talk bu ons on all channels are disabled. A wireless BeltSta on user may
enable a Talk bu on at any  me a er the Mic Kill bu on is pressed and released. The “OFF” indicator appears in place
of the “TALK” indicator on the BeltSta on display and the user will not hear sidetone if both Talk bu ons are OFF.
5- Local Headset Channel LEDs
The four Local Headset Channel LEDs labeled A through D indicate the currently selected intercom channel for
the BaseSta on local headset. Only one channel may be selected at a  me. Pressing the Volume control while in
Opera onal Mode cycles the Channel LEDs in order from A through D.
6- Peak LEDs
The four PEAK LEDs indicate when the mic audio from the local headset is reaching a peak level and is about to
enter into limi ng. These indicators should not be illuminated during normal use. The mic gain for the Local Headset
connector can be adjusted from the “Set Mic Gain” menu, under “BaseSta on Se ngs.” Se ng the mic gain correctly
is cri cal for quality communica on audio.
