5 Tempest®24 00 MasterBelt

MasterBelt Overview

The Tempest MasterBelt is a 2-Channel Tempest BeltSta on that serves as a Tempest BaseSta on. The MasterBelt is

compa ble with exis ng 2-Channel Tempest BeltSta ons. Like a Tempest BaseSta on, the MasterBelt is capable of hos ng

and suppor ng up to  ve standard BeltSta ons in full duplex communica on when opera ng in Normal mode. When

opera ng in Shared or Split mode, the MasterBelt can support an unlimited number of standard BeltSta ons in a listen/

push-to-talk capacity.

The MasterBelt can be situated in a  xed loca on (like a BaseSta on) or worn in a mobile capacity (like a BeltSta on).

This type of ﬂ exibility and mobility enables users to overcome challenges associated with AC power needs,  xed antenna

placement and limited coverage area. With a MasterBelt, groups of Tempest users can eﬀ ec vely move together and

maintain wireless communica on with one another without the need of a tradi onal BaseSta on or  xed antenna.

A MasterBelt has many of the same func onal and cosme c characteris cs of a standard BeltSta on. Talk bu ons, channel

bu ons, volume knobs, and many other features remain the same.

1- Volume- CH A and CH B

In Opera onal Mode, turning the Volume control adjusts the volume of the

audio. Volume indicators appear on the display during adjustment and are

expressed in Decibels (dB).

The Volume control has an op on to be set to “Volume Press” where it requires

a “press and turn” to adjust the volume level. The “Volume Press” op on can be

adjusted under the “Set Controls” sec on of the MasterBelt menu.

Pressing the Volume control in “Dual-listen” mode does nothing. In “Single-

listen” mode, pressing “CH A” enables channel A, and pressing “CH B” enables

channel B . The Volume control has a channel “Delay Switch” op on which

requires the knob to be pressed and held slightly longer in order to switch from

one channel to the other. This feature can be enabled under the “Set Controls”

sec on of the MasterBelt menu.

In Menu Mode, turning either Volume control allows the user to scroll the

op ons of the current menu screen. Pressing the Volume control selects the

op on.

2- Base Bu on

The BASE bu on (when pressed) changes the MasterBelt’s display to show the telemetry status

of all current BeltSta ons logged into the MasterBelt. Once on this screen, pressing the BASE

bu on will cycle through each BeltSta on’s telemetry based on their assigned slot posi on.

3- MENU Bu on

Pressing MENU while the MasterBelt is in Opera onal mode will select Menu Mode, and the Main Menu screen will be

displayed. Once in Menu Mode, pressing MENU again will act as an escape key and will back out of the current menu screen

moving the user up one level. Pressing the MENU bu on while at the Main Menu screen will exit Menu Mode and return

to Opera onal mode. The menu can be locked via a “Menu Lock” feature per MasterBelt.

4- ENTER Bu on

The ENTER bu on operates diﬀ erently depending on the mode of the MasterBelt. In Menu Mode, pressing the ENTER

bu on selects the current menu op on and is the same as pressing a Volume control. A menu item is not selected un l the

ENTER bu on (or Volume control) is pressed.

The ENTER bu on can also ac vate Wireless ISO (wireless talk around).
