82 Tempest®900 2-Channel Wireless Intercom System
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 user will be required to correct the in-
terference at his own expense. Commensurate with EIRP limits specified in FCC Rules 15.247b, this device may not be used with
antennas that exceed 9dB of gain in multi-point applications.
Contains Transmitter Module FCCID: HSW-934
Important FCC and Safety Information
I. Digital Device Statement
A. Tempest BaseStations and wireless BeltStations have been tested and found to comply with the limits for Class B digital
devices, pursuant to Part 15 of the Rules and Regulations of the U.S. Federal Communications Commission (the FCC) . Tempest
products are marketed as Class A digital devices. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
B. This equipment generates, uses, and can radiate radio-frequency energy. If not installed and used in accordance with all
instructions, it may cause harmful interference to radio communications.
C. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be re-
quired to correct the interference at his own expense.
II. Intentional Radiator Statement
A. Tempest BaseStations and wireless BeltStations each employ a modular, low-power radio transceiver module that operates
pursuant to Part 15 of the FCC’s Rules. The module’s FCC Identifier is HSW-934.
B. Operation is subject to the following conditions:
1. A Tempest system may not cause harmful interference to other users of the radio spectrum.
2. Upon notification by a representative of the FCC that a Tempest system is causing harmful interference, use of the system
must be suspended. Operation must not resume until the condition causing the harmful interference has been corrected.
and
3. A Tempest system must accept any interference received, including interference that may cause undesired operation.
C. Tempest Wireless BeltStations contain an internal antenna that is not user replaceable Tempest BaseStations must be used
only with approved antennas either the standard 4” Rubber Whip Antenna supplied with every Tempest BaseStations, with
the 9bBi Directional Corner Reflector Antenna that is available as an option or another approved antenna. Use of any non-ap-
proved antenna, or any modification to any part of a Tempest unit, violates the Tempest System’s warranty, and also constitutes
a violation of the FCC’s Rules and Regulations and of § 302 of the Communications Act of 1934, as amended.
D. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication.
III. RF-Exposure Statement
A. The FCC has adopted limits on the exposure to radio-frequency energy from devices such as the Tempest system. The FCC
adopted these limits by drawing upon the efforts of independent scientific organizations that have engaged in periodic evalu-
ations of the scientific literature. The FCC’s standards are intended to assure the safety of all persons, regardless of age or
health.
B. Tempest has been designed and manufactured to comply with the FCC’s exposure limits. When used with approved anten-
nas, and when used in accordance with all instructions, the Tempest system complies with those exposure limits.
C. Tempest BeltStations have been designed to be worn and used in close proximity to the human body.... what the FCC calls a
“portable” use. The BeltStation unit complies with FCC exposure limits for portable use.
D. To ensure compliance with FCC exposure limits, no person must come closer than 26 cm (ten inches) from either the stan-
dard 4” Rubber Whip Antenna, the optional Directional Corner Reflector Antenna, or other approved antenna whichever is
used with the Tempest BaseStation.
