Introduction
Introduction
In 1991, CoachComm pioneered a new era in sideline communications and CoachComm’s wired systems were quickly recognized
as the best in the industry. Since 1997, CoachComm, LLC has been offering wireless products to meet the communications needs
of the football coaching market beginning with the UC series system. Based on the Telex® BTR/TR 600 digital radios, the UC
system became the standard for sideline communications for Division 1A football as well as for most professional teams.
While very popular, the UC system was limited with regards to its ability to perform in certain RF environments. Each system has
two (2) unique operating frequency sets, therefore a team can either be on frequency set “A” or set “B”. With the proliferation of
digital television broadcast signals in recent years, UC systems have experienced more RF interference from outside sources.
In addition to RF considerations, coaches were demanding increased audio quality, more wireless users, and several other
operational enhancements. Considering all of these factors and operational issues, CoachComm created the new NG series
system.
The CoachComm NG series system is an advanced, multi layered communication system for football coach communications.
NG addressed features not included in its predecessor, UC, with features such as frequency agility, an increased number of
wireless users, substantially better audio quality and a host of other renements.
Even though the NG series represented a huge improvement with issues surrounding user operation, complexity and continuing
problems within the frequency spectrum for Part 74 devices, CoachComm elected to develop a new sideline communications
system that was completely outside of the Part 74 FCC rules and that has enhanced user features and ease of use. The new
system is calledTempest NG. While the wireless portion of theTempest NG system is new technology, the central infrastructure
of theTempest NG system is identical to the previous NG system. Therefore, the nomenclature of “NG” was retained.
The wired portion of the Tempest NG Series system is designed around the Telex® AudioCom® platform. The AudioCom®
Platform is the only sports communications system that employs two very important audio concepts: the balanced line concept
and the transformer isolation concept.
The AudioCom® system uses a balanced line approach to signal transmission. This means that the system is more forgiving
on twisted pair and that it is not necessary to “balance” the dry pair as you have to do in unbalanced systems. This makes for
faster setup and easier conguration changes. The transformer isolation employed in AudioCom® BeltPacks is one of the most
important features of the wired system. This transformer, located in each BeltPack, isolates the user from potential sources of
noise in the dry pair. It may not isolate every noise, but it does remove the most annoying buzzes and crackles associated with
other systems.
Expandability and adaptability are keys to the Tempest NG system. Users can be put into and taken out of the system without
affecting other users. In other systems, taking a user out of the line may cause an increase in system volume or a change in
system impedance resulting in voice quality degradation. In the Tempest NG system, however, adding and removing users is
virtually transparent.
This is the most advanced intercom system in use today. We highly recommend that you thoroughly read and study this manual.
Concepts and practical hints on system setup will help you be more efcient in system administration.

Introduction
A/C Power Warning
User should exercise extreme care when working with electricity. Additional care should be used when working with electricity
outdoors in inclement weather. Keep all electrical connections internal to the system unit and plug the system only into a ground
fault interrupting circuit.
FCC Information
This unit has been tested and found to comply with the limits for a class A digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio frequency energy, and if not installed and
used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case, the users will be required to correct the
interference at their own expense. Commensurate with EIRP limits specied in FCC Rules 15.247b, this device may not be
used with antennas that exceed 9dB of gain in multi-point applications. For use in RF exposure mobile or xed conditions, the
antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons.

FCC Regulations — CoachComm strongly urges our users of wireless products to research and where applicable pursue licensing
with the Federal Communications Commission. You may wish to seek qualied legal assistance to assist you in this process.
You should respect the fact that other frequency users in your area may have a legal right to the frequency you are using. FCC
regulations stipulate that the end user of this equipment is responsible for lawful use of this product.

Introduction
What makes Tempest so different?
CoachComm has been building wired systems for over 16-years and wireless systems for over 11-years to supply quality
communications to D-1A teams nationwide. Therefore, CoachComm’s knowledge of wireless technology in the D1A football
arena is vast and our experience is deep. When it came time to build the next generation of equipment to service that industry
– CoachComm was up to the challenge.
Tempest is so unique that it has taken not only the football world, but other wireless intercom applications by storm! Simply put,
Tempest is the world’s rst fully featured, 2.4 GHz, frequency hoping spread spectrum wireless intercom. Tempest now comes
in a 900 MHz model offering the same features.
Fully Featured
Tempest is the rst wireless intercom system to employ the feature set that end users demand. Some of the unique features
include:
»Durable industrial design
»No FCC license required
»No frequency coordination required
»Easy user set-up and operation
»Multiple battery options
»Call with vibrate
»Remote Mic Kill
»Unlimited number of BeltPacks
»Remote transceiver
»And much more..
These features come together to form an incredible product called Tempest. Tempest wireless is the heart of the Tempest NG
sideline communications system. Tempest wireless together with enhanced tools for the wired portion of the system make for
an incredibly robust, easy to operate system.
2.4 GHz
Previous NG and UC systems have operated in the FCC part-74 band. Over the past few years, the FCC has been relocating TV
stations from the old analog domain to the new digital era. As a part of this process, many of the frequencies used by the NG
and UC systems have either become over crowded or are no longer a legal option.
CoachComm designed the newTempest wireless product to operate in the 2.4 GHz frequency band. This band is open for general
use and does not require special licensing by the end-user. In addition, this band is specically set-aside by the FCC for devices
such asTempest that work well together even in a crowded RF spectrum. The idea is that devices constructed to work in this band
are supposed to work well even if there are other devices in this same frequency band.
900 MHz
In addition to the 2.4 GHz model, theTempest family of products now includes a 900 MHz model,Tempest NG900. The 900 MHz
model is a technologically-enhancing accessory to existing 2.4 GHz systems, giving users more options on game day. The user
inferface is exactly the same as the 2.4 GHz model, therefore no new training is required. This band is also a license-free band.
Frequency-Hopping Spread Spectrum
Frequency-Hopping Spread Spectrum (FHSS) is a means of RF transmission. In FHSS, the signal hops to various frequencies
– hence the name. In doing so, it spreads the data (voice in our case) across a wide area of the RF spectrum. Devices such as
Tempest collide constantly with other devices in that frequency spectrum and must have mechanisms built into their protocol to
allow for data redundancy to provide acceptable user performance. The particular methods used in the Tempest FHSS protocol
are covered by seven (7) U. S. patents and represent the state of the art in FHSS technology.
