RF Radiation Information
This product must be restricted to operations in an 
occupational/controlled RF exposure environment.Users 
must be fully aware of the hazards of the exposure and 
able to exercise control over their RF exposure to qualify 
for the higher exposure limits. 
Radio Frequency (RF) is a frequency of electromagnetic 
radiation in the range at which radio signals are 
transmitted. RF technology is widely used in 
communication, medicine, food processing and other 
RF Radiation Safety
In order to ensure user health, experts from relevant 
industries including science, engineering, medicine and 
health work with international organizations to develop 
standards for safe exposure to RF radiation. These 
standards consist of: 
  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; 
  International Commission on Non-Ionizing Radiation 
Protection (ICNIRP) 1998. 
FCC Regulations 
Federal Communication Commission (FCC) requires 
that all radio communication products should meet the 
requirements set forth in the above standards before 
they can be marketed in the U.S, and the manufacturer 
shall post a RF label on the product to inform users 
of operational instructions, so as to enhance their 
occupational health against exposure to RF energy. 
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 not more than 50% of the time and 
always adhere to the following procedures: 
  RF energy will be generated only when the radio is 
transmitting. 
  The radio must be 2.5 centimeters away from human 
body when transmitting. 
FCC Statement
This equipment has been tested and found to comply with the 
limits for a Class B digital device, pursuant to part 15 of FCC 
Rules. These limits are designed to provide reasonable 
protection against harmful interference in a residential 
installation. This equipment generates and can radiate radio 
frequency energy. If not installed and used in accordance with 
the instructions, it may cause harmful interference to radio 
communications. However, there is no guarantee that 
interference will not occur in a particular installation. 
Verification of harmful interference by this equipment to 
radio or television reception can be determined by turning it 
off and then on. The user is encouraged to try to correct the 
interference by one or more of the following measures: 
zReorient or relocate the receiving antenna. Increase the 
separation between the equipment and receiver. 
zConnect the equipment into an outlet on a different 
circuit to that of the receiver's outlet. 
zConsult the dealer or an experienced radio/TV technician 
for help. 
Operation is subject to the following two conditions:   
zThis device may not cause harmful interference. 
zThis device must accept any interference received, 
including interference that may cause undesired 
operation. 
Note: Changes or modifications to this unit not expressly 
approved by the party responsible for compliance could void 
the user's authority to operate the equipment. 
RF Exposure Compliance and 
Control Guidelines and Operating
Instructions
To control your exposure and  ensure compliance with the 
occupational/controlled environmental exposure limits, 
always adhere to the following procedures. 
Guidelines: 
zDo not remove the RF Exposure Label from the device. 
zUser awareness instructions should accompany device 
when transferred to other users. 
zDo not use this device if the operational requirements 
described herein are not met. 
Operating Instructions: 
zTransmit no more than the rated duty factor of 50% of the 
time. To transmit (talk), push the Push-To-Talk (PTT) 
key. To receive calls, release the PTT key. Transmitting 
50% of the time, or less, is important because the radio 
generates measurable RF energy only when transmitting 
(in terms of measuring for standards compliance). 
zKeep the radio unit at least 2.5 cm away from the face. 
Keeping the radio at the proper distance is important as 
RF exposure decreases with distance from the antenna. 
The antenna should be kept away from the face and eyes. 
zWhen worn on the body, always place the radio in a 
Hytera-approved holder, holster, case, or body harness or 
by use of the correct clip for this product. Use of 
non-approved accessories may result in exposure levels 
which exceed the FCC's occupational/controlled 
environmental RF exposure limits. 
zUse of non-approved antennas, batteries, and accessories 
causes the radio to exceed the FCC RF exposure 
guidelines. 
zContact your local dealer for the optional accessories of 
the product. 
EU Regulatory Conformance
        
compliance with the essential requirements and other 
relevant provisions of the Directive 2014/53/EU. 
Please note that the above information is applicable to

Troubleshooting
Phenomena Analysis Solution
The radio fails to power 
on. 
The battery may be improperly installed.  Remove the battery and then reattach it. 
The battery power may be used up.  Recharge or replace the battery. 
The battery may be poorly connected due 
to dirtied or damaged battery contacts. 
Clean the battery contacts. If the problem cannot 
be solved, contact your dealer or authorized service 
center for inspection and repair. 
During receiving, 
the voice is weak, 
discontinuous or totally 
inactive. 
The battery voltage may be low.  Recharge or replace the battery. 
The volume level may be low.  Increase the volume by rotating the Volume Control 
Knob. 
The antenna may be loosened or 
improperly installed.  Reattach the antenna after turning off the radio. 
The speaker may be blocked or 
damaged. 
Clean the surface of the speaker. If the problem 
cannot be solved, contact your dealer or authorized 
service center for inspection and repair. 
You cannot
