A/C Power Warning
Users should exercise extreme care when working with electricity. Addional care should be
used when working with electricity outdoors in inclement weather. When working outdoors or
near water, always connect the system into a ground-fault interrupng circuit.
There are no user-serviceable parts inside the Tempest MasterBelt. Opening the case may expose dangerous electrical
components, and will void the warranty.
ALERT SYMBOL – Indicates important informaon.
CAUTION SYMBOL – Indicates a potenal to damage equipment.
DANGER SYMBOL – indicates a potenal safety hazard.
Baery Safety
Baery Transportaon
Rechargeable lithium baeries are subject to special regulaon by U.S. and
Internaonal laws, parcularly regarding transportaon on passenger aircra.
However, individual baeries installed in consumer electronics are not restricted,
provided there are only the correct numbers and types of baeries as may be needed
to operate the electronic equipment.
Your Tempest MasterBelt Wireless Intercom System includes rechargeable lithium-polymer baeries that power the
MasterBelt and BeltStaons. To ensure that there is no violaon of U.S. or Internaonal laws, and to ensure your own
safety, always:
• Transport rechargeable lithium baeries installed in the equipment they are intended to power.
• Transport spare baeries in a padded case, separated from one another.
• Never transport your rechargeable lithium baeries bundled together.
• Never transport more than 12 lithium baeries in a single package.
Lithium-polymer baeries include a chemistry that is intended to overcome the dangers associated with lithium ion
baeries. In addion, the baeries that accompany your Tempest Wireless system include protecve circuits to further
reduce the possibility of a dangerous reacon associated with charging or discharging beyond safe limits. With reasonable
care you can expect many years of safe and reliable power from your baeries.

4Tempest®2400 MasterBelt™
Tempest baeries are not subject to transport regulaons of dangerous goods because they fulll the following regulatory
provisions:
»ADR 188
»IATA A45
»IMDG 188
Baery Storage
Long-term storage of baeries at maximum charge can result in permanent loss of capacity.
For long term storage of baeries, charge/discharge the baeries to approximately 60% of capacity. Baeries stored for
longer than one year should be recharged to 60% annually. Trickle charging is not recommended due to the very low self
discharge rate of the baeries.
As with all baeries:
• Do not burn.
• Do not expose baeries to excessive heat such as sunshine, re or other heat sources.
• CAUTION – Danger of explosion if baery is incorrectly replaced. Replace only with the same or equivalent type.
• Properly dispose of used baeries promptly.
• Keep away from children.
Maintenance and Care
Cleaning
Generally, the Tempest Wireless hardware should be cleaned only with a dry cloth. A so cloth with rubbing alcohol may
be used to wipe the units if needed. Never spray solvents or chemicals onto the units.
Because of Tempest’s weather resistant design, it is not highly suscepble to dust or airborne contaminants. However, all
electronic devices can be suscepble to parculate contaminaon. If exposed to an extremely dusty environment, contact
an authorized Tempest service center for internal cleaning.
Temperature and Humidity
Ideally, all electronics should be stored and used in a controlled environment with moderate temperature and humidity.
Tempest components are designed to be very durable, and can tolerate a wide range of environmental condions.
Install the MasterBelt in a locaon where it will not be exposed to extreme weather condions. Protect the unit against
dust or moisture. Always protect any AC power connecons from the elements with safety in mind.
The MasterBelt and BeltStaons are designed to work wherever people work. While the design is weather resistant, the
headset XLR connector on the boom is not waterght. MasterBelts or BeltStaons should not be submerged in liquids.
Protect the baery compartment from water when changing baeries. The baery compartment oers a route to the
electronic circuitry.

5Tempest®2400 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 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 e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

MasterBelt Set-up
Selecng MasterBelt Locaon
Antenna Paern
The Tempest MasterBelt and BeltStaon have the same internal patch antenna located
at the top-end of the unit. It is important to understand the antenna propagaon when
determining the locaon of the MasterBelt during operaon. The MasterBelt and
BeltStaon antenna is a linear polarized omnidireconal antenna. However, due to its
posioning at the top of the BeltStaon, the antenna is aenuated at it’s boom thus
creang a direconal paern.
Fixed Locaon
Despite having no external antenna, the
Tempest MasterBelt can be used in the same
manner as tradional Tempest BaseStaons.
However, there could be an impact on the
system’s range depending on the chosen
locaon and orientaon.
When determining a locaon to place the
MasterBelt, use the same approach used
with Tempest BaseStaons and/or Remote
Transceivers. Be sure that line-of-sight
from MasterBelt to standard BeltStaons is
maintained for opmal performance. Any
obstrucons can cause the RF signal to
become aenuated and diminish range and
performance.
Mobile Operaon
When using the MasterBelt in a mobile applicaon, system range will be less due to body shielding.

Baery Charging and Installaon
With the Lithium-Polymer baeries installed in the baery compartment, plug the AC
end of the supplied 5VDC Charger/Power Supply into a standard AC wall outlet. Open the
rubberized access cover on the side of the MasterBelt or BeltStaon and plug the USB end
of the Charger/Power Supply into the USB connector. The Lithium-Polymer baeries will take
approximately 2¾ hours to charge from completely empty to completely full. This me is the
same with the unit turned ON or OFF. A new, fully charged baery should power a Tempest
MasterBelt or BeltStaon for approximately nine hours. Fast charging with the supplied fast
charger requires a temperature range of 32° – 113° F.
Baeries can receive more than 500 charge cycles, and
connue to maintain more than 70% of their power rang. The
Tempest baery indicator will maintain its accuracy as baery
life decreases.
Alternavely, remove the Lithium-Polymer rechargeable baery from the unit and insert it into
the oponal 5-Bay Baery Charger. The Lithium-Polymer baeries will take approximately 2½
hours to charge from completely empty to completely full. See the baery charger manual
for addional details.
The Tempest MasterBelt and BeltStaon Baery Compartment holds either one
Tempest Lithium-Polymer rechargeable baery or three standard alkaline AA cells.
Lithium-Polymer baeries are the primary power source. High quality alkaline AA
cells may be used in situaons where Lithium-Polymer baeries are not available or
are not charged. One Lithium-Polymer baery comes standard with each Tempest
MasterBelt or BeltStaon. Addional Lithium-Polymer baeries may be purchased.
Contact your dealer or distributor to purchase addional baeries. The Lithium-
Polymer baeries supplied with your Tempest Wireless system are warranted for 90
days from the date of purchase.
Lithium-Polymer baeries oer 7+ hours of baery life in a MasterBelt and up to
9 hours of baery life in a BeltStaon. The baeries recharge in approximately 2¾
hours.
Lithium-Polymer baeries ship from the factory with approximately 50% charge. It will not damage the Lithium-Polymer
baeries to use them without charging them rst. This will, however result in shorter run me unl the Lithium-Polymer
baery is fully charged. When possible, charge Lithium-Polymer baeries to full capacity to ensure full baery life prior to
use.
Using (3) alkaline AA baeries can provide up to four hours of baery life. Use only high quality alkaline AA cells. This will
provide enough me to fully charge the Lithium-Polymer baery.
To remove the baery door, press down on the thumb markings and pull the baery door toward the boom of the unit.
To remove baeries from the baery compartment, turn the MasterBelt baery side down and tap the boom of the unit
on the palm of your other hand.
Please be careful to insert alkaline AA baeries according to the marked polarity. All of the alkaline AA cells must be
oriented the same direcon. If the baery cover does not close properly, the baery may not be inserted correctly.

MasterBelt Power ON/OFF
• The Power ON/OFF buon is used to turn the MasterBelt ON or
OFF.
• Press and hold the Power ON/OFF buon for two seconds to turn
the MasterBelt ON.
• Press and hold for four seconds to turn the MasterBelt OFF.
Selecng a Frequency Band
The Tempest MasterBelt 2.4GHz model is approved for license free use in most countries. However, due to dierences
in radio spectrum regulaons, a few countries require that 2.4GHz equipment limit or adjust its RF spectrum operaon.
Always determine if there are country specic frequency restricons that apply and select the required frequency band as
described below. Tempest performs RF frequency adjustment automacally when you select the appropriate frequency
band from the “Tech Menu.” It is only necessary to use this feature if you use Tempest in one of the countries with special
frequency requirements. Otherwise, Band 1 should be used for maximum RF performance.
If the Tempest Wireless system is transported to a country with special requirements, navigate to the Radio Conguraon
screen in the “Tech Menu” to select the appropriate frequency band from the “Set Band” menu screen of the MasterBelt.
Aer changing the frequency band selecon it is necessary to “pair” each BeltStaon with the MasterBelt so the informaon
can be transmied from the MasterBelt to the BeltStaon. See the “Pairing BeltStaons with MasterBelt” secon of this
manual for more informaon on pairing.

Set Network Number and Lockout Key
The Network Number determines the frequency hopping paern for the MasterBelt and its respecve BeltStaons. This is
a key operaonal parameter and is represented by a number between 0 and 63.
Using dierent conguraons or systems in close proximity can cause interference and diminish performance. Mulple
MasterBelt conguraons within the same proximity should maintain a respectable distance from one another and always
ulize dierent network numbers.
The Lockout Key prevents systems with the same Network Number from trying to communicate with each other and is
represented by a number between 0 and 255. Together, the Network Number and Lockout Key represent more than 16,000
possible combinaons to minimize the possibility of inter-system interference.
The Network Numbers and Lockout Keys for Tempest Wireless are set to factory defaults before leaving the factory. Always
adjust the Network Number and Lockout Key of any Tempest Wireless that are known to operate in close proximity to one
another as described below. Users should conrm these sengs to minimize the opportunity for improper performance
issues.
Failure to set a unique Network Number and Lockout Key may result in poor system performance caused by interference
from another Tempest Wireless system using the same Network Number and Lockout Key. Tempest BeltStaons received
their Network Number and Lockout Key’s from their respecve MasterBelt, therefore it is not possible to manipulate
Network Numbers and Lockout Keys to gain unauthorized access to a communicaon channel.

15 Tempest®2400 MasterBelt™
Pairing BeltStaons to MasterBelt
Pair BeltStaon to MasterBelt:
Conrm that the MasterBelt is powered ON and in Operaonal Mode (not
in Menu Mode) and that the BeltStaon is powered OFF. Conrm that the
MasterBelt’s Network Number and Lockout Key are adjusted as needed. See the
secon on Set Network Number and Lockout Key.
Plug one end of the pairing cable into the MasterBelt and the other end into the
BeltStaon.
The pairing cable is a standard 3.5mm
(1/8 in.) Male to Male stereo patch cord.
Turn the BeltStaon power ON by pressing and holding the BeltStaon Power ON/OFF buon for two seconds. The pairing
process will begin automacally. Watch for the message “Pairing Complete” to appear briey on the BeltStaon display.
The BeltStaon will automacally re-inialize.
Name MasterBelt
Name the MasterBelt with a descripve name. The MasterBelt name can include up to 14 characters. Prior to a name being
assigned, a hexadecimal serial number is displayed as a default.
The MasterBelt name will appear on the LCD Display, on the BeltStaon LCD display, and in the BeltStaon’s menu under
“Select Base.”
To name each MasterBelt:
1. On the MasterBelt press MENU and select “Belt Sengs,” then “Name BeltStaon.”
2. Rotate the Volume control to move the underscore “_” to select the character to be changed.
3. Press ENT and noce the underscore changes to a pointer “Λ” under the selected character.
4. Rotate the Volume control to scroll through the character list. Press ENT to select the new character. Characters always
replace and never insert. Repeat as needed.
5. Press ENT to save the new name aer all characters are complete. Failure to press ENT to save will clear all changes.
6. Press MENU to escape to the Operaon Mode screen.
Naming the BeltStaon works the same as naming the MasterBelt.

16 Tempest®2400 MasterBelt™
Congure BeltStaon Sengs
Name BeltStaons
Naming BeltStaons is the same as naming a MasterBelt. See the “Name MasterBelt” for more informaon on naming BeltStaons.
Adjust Mic Gain
Set the Mic Gain properly to ensure the best audio quality. To set the Mic Gain for the BeltStaon Headset:
1. Press MENU to enter Menu Mode. From the Main Menu, select “Set Controls,” then “Mic Gain.”
2. While at the Mic Gain screen, talk into the headset microphone at a louder than normal level and adjust the Volume control
unl the PEAK LEDs just start to light at the loudest parts of the audio. Press ENT to accept the changes.
Mic Gain can be set in the BeltStaon without acvang the Talk buon. This allows private mic gain adjustment during
live events.
When the Mic Gain is set too high, it is possible to induce feedback or echo. When set too low, words can be clipped by
the low level noise gate or sound too quiet to other listeners. Headsets by dierent manufacturers or dierent models
of headsets will require widely varying Mic Gain sengs. When seng microphone gain, it is best to err toward a seng
that is too low, rather than too high. This will help reduce unwanted echo in the system when that microphone is enabled.
Adjust Sidetone
1. Press MENU to enter Menu Mode. From the Main Menu, select “Set Controls,” then “Mic Gain.”
2. Rotate the Volume knob and scroll to “Belt Sengs” on the display
3. Press ENT
4. Scroll to “Sidetone” and press ENT (or the Volume knob) to select
Sidetone value is expressed in Decibels (dB). You will see a level indicator with a numeric value between -30 dB to -6 dB.
Speak into the headset microphone at a typical speaking level and adjust the sound of your own voice in your headset. Pay
close aenon to the TALK buon LED when speaking into the mic. The LED will light red when clipping is occurring. Once
you’ve determined a proper level, press ENT to accept the changes.
Press MENU to move up one level in the menu tree. Press MENU repeatedly to exit Menu Mode and return to Operaonal
Mode. If no other items are selected, Menu Mode automacally exits and returns to Operaonal Mode aer about three
minutes.
Adjust BeltStaon Slot
The MasterBelt Slot Assignment only aects the order that the MasterBelt Operaonal screen displays the BeltStaon
informaon when the MasterBelt is in the Stac display mode. If the MasterBelt is rounely used as a communicaon port
or for monitoring BeltStaons, it may be more convenient to always have the same user appear in the same posion on the
MasterBelt display. This is a personal preference seng.
In the MasterBelt “Tech Menu,” choose Stac or Dynamic from the “Slot Assignment” screen. Dynamic,the default, will
work without any adjustment, and always displays BeltStaons in alpha-numeric order by name.
Stac will be the preferred choice for users who are using only one MasterBelt and want to ensure that a BeltStaon that is
logged in will always appear in the same locaon (slot) on the MasterBelt display. When selecng Stac slot assignments,
you must also enter the Tech Menu for each BeltStaon and assign each BeltStaon a dierent slot (1 – 5).
