Battery Safety
Battery Transportation
Rechargeable lithium batteries are subject to special regulation by U.S. and International
laws, particularly regarding transportation on passenger aircraft. However, individual
batteries installed in consumer electronics are not restricted, provided there are only
the correct numbers and types of batteries as may be needed to operate the electronic
equipment.
Your Tempest MasterBelt Wireless Intercom System includes rechargeable lithium-polymer batteries that power the MasterBelt and BeltStations.
To ensure that there is no violation of U.S. or International laws, and to ensure your own safety, always:
• Transport rechargeable lithium batteries installed in the equipment they are intended to power.
• Transport spare batteries in a padded case, separated from one another.
• Never transport your rechargeable lithium batteries bundled together.
• Never transport more than 12 lithium batteries in a single package.
Lithium-polymer batteries include a chemistry that is intended to overcome the dangers associated with lithium ion batteries. In addition, the
batteries that accompany your Tempest Wireless system include protective circuits to further reduce the possibility of a dangerous reaction
associated with charging or discharging beyond safe limits. With reasonable care you can expect many years of safe and reliable power from
your batteries.

Tempest MasterBelt Operating Manual
Tempest batteries are not subject to transport regulations of dangerous goods because they fulll the following regulatory provisions:
• ADR 188
• IATA A45
• IMDG 188
Battery Storage
Long-term storage of batteries at maximum charge can result in permanent loss of capacity.
For long term storage of batteries, charge/discharge the batteries to approximately 60% of capacity. Batteries 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 batteries.
As with all batteries:
• Do not burn.
• Do not expose batteries to excessive heat such as sunshine, re or other heat sources.
• CAUTION – Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.
• Properly dispose of used batteries promptly.
• Keep away from children.
Maintenance and Care
Cleaning
Generally, the Tempest Wireless hardware should be cleaned only with a dry cloth. A soft 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 susceptible to dust or airborne contaminants. However, all electronic devices can
be susceptible to particulate contamination. 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 conditions.
Install the MasterBelt in a location where it will not be exposed to extreme weather conditions. Protect the unit against dust or moisture. Always
protect any AC power connections from the elements with safety in mind.
The MasterBelt and BeltStations are designed to work wherever people work. While the design is weather resistant, the headset XLR connector
on the bottom is not watertight. MasterBelts or BeltStations should not be submerged in liquids. Protect the battery compartment from water
when changing batteries. The battery compartment offers a route to the electronic circuitry.

Tempest MasterBelt Operating Manual
MasterBelt Overview
The Tempest MasterBelt is a 2-Channel Tempest BeltStation that serves as a Tempest BaseStation. The MasterBelt is compatible with existing
2-Channel Tempest BeltStations. Like a Tempest BaseStation, the MasterBelt is capable of hosting and supporting up to ve standard
BeltStations in full duplex communication when operating in Normal mode. When operating in Shared or Split mode, the MasterBelt can
support an unlimited number of standard BeltStations in a listen/push-to-talk capacity.
The MasterBelt can be situated in a xed location (like a BaseStation) or worn in a mobile capacity (like a BeltStation). 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 effectively move together and maintain wireless communication with one another without the need of
a traditional BaseStation or xed antenna.
A MasterBelt has many of the same functional and cosmetic characteristics of a standard BeltStation. Talk buttons, channel buttons, volume
knobs, and many other features remain the same.
1- Volume- CH A and CH B
In Operational Mode, turning the Volume control adjusts the volume of the audio.
Volume indicators appear on the display during adjustment and are expressed in

Tempest MasterBelt Operating Manual
MasterBelt Setup
Selecting MasterBelt Location
Antenna Pattern
The Tempest MasterBelt and BeltStation have the same internal patch antenna located at the top-end
of the unit. It is important to understand the antenna propagation when determining the location
of the MasterBelt during operation. The MasterBelt and BeltStation antenna is a linear polarized
omnidirectional antenna. However, due to its positioning at the top of the BeltStation, the antenna is
attenuated at its bottom, thus creating a directional pattern.
Fixed Location
Despite having no external antenna, the Tempest
MasterBelt can be used in the same manner as traditional
Tempest BaseStations. However, there could be an impact
on the system’s range depending on the chosen location
and orientation.
When determining a location to place the MasterBelt,
use the same approach used with Tempest BaseStations
and/or Remote Transceivers. Be sure that line-of-sight
from MasterBelt to standard BeltStations is maintained
for optimal performance. Any obstructions can cause the
RF signal to become attenuated and diminish range and
performance.
Mobile Operation
When using the MasterBelt in a mobile application, system range will be less due to body shielding.

Battery Charging and Installation
With the Lithium-Polymer batteries installed in the battery 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 BeltStation and plug the USB end of the Charger/Power Supply into the USB connector. The
Lithium-Polymer batteries will take approximately 2¾ hours to charge from completely empty to completely
full. This time is the same with the unit turned ON or OFF. A new, fully charged battery should power a Tempest
MasterBelt or BeltStation for approximately nine hours. Fast charging with the supplied fast charger requires a
temperature range of 32° – 113° F.
Batteries can receive more than 500 charge cycles, and continue to maintain more than 70% of their power
rating. The Tempest battery indicator will maintain its accuracy as battery life decreases.
Alternatively, remove the Lithium-Polymer rechargeable battery from the unit
and insert it into the optional 5-Bay Battery Charger. The Lithium-Polymer
batteries will take approximately 2½ hours to charge from completely empty to
completely full. See the battery charger manual for additional details.
The Tempest MasterBelt and BeltStation Battery Compartment holds either one Tempest Lithium-Polymer
rechargeable battery or three standard alkaline AA cells. Lithium-Polymer batteries are the primary power source.
High quality alkaline AA cells may be used in situations where Lithium-Polymer batteries are not available or
are not charged. One Lithium-Polymer battery comes standard with each Tempest MasterBelt or BeltStation.
Additional Lithium-Polymer batteries may be purchased. Contact your dealer or distributor to purchase
additional batteries. The Lithium-Polymer batteries supplied with your Tempest Wireless system are warranted for 90 days from the date of
purchase.
Lithium-Polymer batteries offer 7+ hours of battery life in a MasterBelt and up to 9 hours of battery life in a BeltStation. The batteries recharge
in approximately 2¾ hours.
Lithium-Polymer batteries ship from the factory with approximately 50% charge. It will not damage the Lithium-Polymer batteries to use them
without charging them rst. This will, however result in shorter run time until the Lithium-Polymer battery is fully charged. When possible, charge
Lithium-Polymer batteries to full capacity to ensure full battery life prior to use.
Using (3) alkaline AA batteries can provide up to four hours of battery life. Use only high quality alkaline AA cells. This will provide enough time
to fully charge the Lithium-Polymer battery.
To remove the battery door, press down on the thumb markings and pull the battery door toward the bottom of the unit.
To remove batteries from the battery compartment, turn the MasterBelt battery side down and tap the bottom of the unit on the palm of your
other hand.
Please be careful to insert alkaline AA batteries according to the marked polarity. All of the alkaline AA cells must be oriented the same
direction. If the battery cover does not close properly, the battery may not be inserted correctly.

MasterBelt Power ON/OFF
• The Power ON/OFF button is used to turn the MasterBelt ON or OFF.
• Press and hold the Power ON/OFF button for two seconds to turn the MasterBelt
ON.
• Press and hold for four seconds to turn the MasterBelt OFF.
Selecting a Frequency Band
The Tempest MasterBelt 2.4GHz model is approved for license-free use in most countries.
However, due to differences in radio spectrum regulations, a few countries require that 2.4GHz equipment limit or adjust its RF spectrum
operation. Always determine if there are country specic frequency restrictions that apply and select the required frequency band as described
below. Tempest performs RF frequency adjustment automatically 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guration screen in the “Tech
Menu” to select the appropriate frequency band from the “Set Band” menu screen of the MasterBelt.
After changing the frequency band selection it is necessary to “pair” each BeltStation with the MasterBelt so the information can be transmitted
from the MasterBelt to the BeltStation. See the “Pairing BeltStations with MasterBelt” section of this manual for more information on pairing.

Tempest MasterBelt Operating Manual
Set Network Number and Lockout Key
The Network Number determines the frequency hopping pattern for the MasterBelt and its respective BeltStations. This is a key operational
parameter and is represented by a number between 0 and 63.
Using different congurations or systems in close proximity can cause interference and diminish performance. Multiple MasterBelt congurations
within the same proximity should maintain a respectable distance from one another and always utilize different 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 combinations 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 settings 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 BeltStations received their Network Number and Lockout Key’s
from their respective MasterBelt, therefore it is not possible to manipulate Network Numbers and Lockout Keys to gain unauthorized access to a
communication channel.

Name the MasterBelt with a descriptive 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 BeltStation LCD display, and in the BeltStation’s menu under “Select Base.”
To name each MasterBelt:
1. On the MasterBelt press MENU and select “Belt Settings,” then “Name BeltStation.”
2. Rotate the Volume control to move the underscore “_” to select the character to be changed.
3. Press ENT and notice the underscore changes to a pointer “^” 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 after all characters are complete. Failure to press ENT to save will clear all changes.
6. Press MENU to escape to the Operation Mode screen.
Naming the BeltStation works the same as naming the MasterBelt.
