standards and guidelines (listed below) regarding human exposure to radio frequency
electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for
occupational/controlled RF exposure environment at operating duty factors of up to 50%
transmitting and is authorized by the FCC 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.
● The device complies with SAR and/or RF field strength limits of RSS-102 requirement and
contact information where the user can obtain Canadian information on RF exposure and
compliance.
Your radio complies with the following of RF energy exposure standards and
guidelines
● United States Federal Communications Commission, Code of Federal Regulations; 47CFR
part 2 sub-part J
● American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers
(IEEE) C95. 1-1992
● Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1999 Edition
● 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:
● Gain of antenna must not exceed 3.5dBi for VHF and 7.0dBi for UHF.
● Antenna Installation: Install the mobile antenna at least 100 cm away from your body, in
accordance with the requirements of the antenna manufacturer/supplier.
Transmit and Receive

Installation
Before you install the radio in a vehicle, be sure to read the following instructions carefully:
Instructions
z The radio operates with cathode-grounded power supply of 13.6V ± 15％ only. Please check
polarity and voltage of the power supply on the vehicle before you install the radio.
z Please check how long the screws will extend from the bottom surface of the radio, before you
install the radio. Drill the mounting hole cautiously to avoid damage to the vehicle wiring and other
parts.
z Please connect Hytera supplied antenna and power cord to the radio, before you install it in the
bracket. And make sure the antenna and power cord is dedicated for Hytera digital radios.
z Install the radio with Hytera supplied mounting bracket, to avoid radio looseness in case of
accidents. The loose radio may cause bodily injury.
z Install the radio in a location where it’s easy to reach the front panel controls.
z Please make sure there’s sufficient space at back of the radio for wiring.
z When the fuse for DC power cord needs replacement, it must be replaced by a fuse with the same
specification.
Installation Tools
z Electric drill
z Cross head screwdriver
z Hex socket sleeve (used for 4.8*20mm self-tapping screws)
Installation Steps
1. Install the bracket in a location where it’s easy to operate the radio.
2. Connect accessories such as antenna and power cord to the radio.
3. Slide the radio into the mounting bracket and secure it using the locking knobs.
