User Safety, Training, and General Information
READ THIS IMPORTANT INFORMATION ON SAFE AND EFFICIENT OPERATION
BEFORE USING YOUR HYT PORTABLE TWO-WAY RADIO.
Compliance with RF Energy Exposure Standards
Your HYT two-way radio is designed and tested to comply with a number of national and
international standards and guidelines (listed below) regarding human exposure to radio
frequency electromagnetic energy. This radio complies with the IEEE (FCC) and ICNIRP
exposure limits for occupational/controlled RF exposure environment at duty cycles of
up to 50% talk-50% listen and should be used for occupational use only. In terms of
measuring RF energy for compliance with the FCC exposure guidelines, your radio
radiates measurable RF energy only while it is transmitting (during talking), not when it
is receiving (listening) or in standby mode.
Note: The approved batteries supplied with this radio are rated for a 5-5-90 duty cycle
(5% talk-5% listen-90% standby), even though this radio complies with the FCC
occupational RF exposure limits at duty cycles of up to 50% talk.
Your HYT two-way radio complies with the following of RF energy exposure
standards and guidelines:
z United States Federal Communications Commission, Code of Federal Regulations;
47CFR part 2 sub-part J
z American National Standards Institute (ANSI)/Institute of Electrical and Electronic
Engineers (IEEE) C95. 1-1992
z Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1999 Edition
z International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
Operational Instructions and Training Guidelines
To ensure optimal performance and compliance with the occupational/controlled
environment RF energy exposure limits in the above standards and guidelines, users
should transmit no more than 50% of the time and always adhere to the following
procedures:
Transmit and Receive
To transmit (talk), push the Push-To-Talk (PTT) button; to receive, release the PTT
button.
Hand-held radio operation
Hold the radio in a vertical position with the microphone one to two inches (2.5 to 5 cm)
away from the lips.
Body-worn operation
z Always place the radio in an HYT approved clip, holder, holster, case, or body harness
for this product. Use of non-HYT-approved accessories may exceed FCC RF
exposure guidelines.
Antennas & Batteries
4
z Use only HYT approved, supplied antenna or HYT approved replacement antenna.
Unauthorized antennas, modifications, or attachments could damage the radio and
may violate FCC regulations.
z Use only HYT approved, supplied batteries or HYT approved replacement batteries.
Use of non- HYT -approved batteries may exceed FCC RF exposure guidelines.
Approved Accessories
For a list of HYT approved accessories, see the accessories page of this user manual or
visit the following website which lists approved accessories: http://www.HYT.com.cn
FCC Compliance
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
z Reorient or relocate the receiving antenna.
z Increase the separation between the equipment and receiver.
z Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
z Consult the dealer or an experienced radio/TV technician for help.
Modifications not authorized by the manufacturer may void users authority to operate
this device.
FCC Requirements
Your radio must be properly licensed by the Federal Communications Commission prior
to use. Your HYT dealer can assist you in meeting these requirements. Your dealer will
program each radio with your authorized frequencies, signaling codes, etc., and will be
there to meet your communications needs as your system expands.
Note
The term "IC": before the certification / registration number only signifies that the
Industry Canada technical specification were met.
SAR Information
SAR:
THIS MODEL DEVICE MEETS THE GOVERN-MENTS REQUIREMENTS FOR
EXPOSURE TO RADIO WAVES.
For body worm operation, this phone has been tested and meets the FCC RF exposure
guidelines when used with an accessory that contains no metal,and that positions the
antenna of the two-way radio a minimum of 2.5cm from the body.The SAR values of this
two-way radio are 0.93 w/kg (Face Hold) and 1.74 w/kg (Body Worn).Use of other
accessories may not ensure compliance with the FCC RF exposure guidelines
5
The FCC has granted an Equipment Authorization for this model device with all reported
SAR levels evaluated as in compliance with the FCC RF exposure guidelines.SAR
information on this model device is on files with the FCC and can be found under the
Display Grant section of http://www.fcc.gov/oet/fccid.after searching on FCC ID:
R74TC3600KU6. In the U.S. and Canada,the SAR limit for mobile two-way radio used
by the pulic is 5 Watts/kg(W/kg) averaged over one gram of tissue.The standard
incorporates a substantial margin of safety to give additional protection for the public
and to account for any variations in usage
