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.
RF Radiation Prole
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 elds. It may generate radiation during use.
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;

/EU.
As certied by the qualied laboratory, the product is in compliance with the essential requirements and other relevant provisions of the Directive 2014/53
●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.
EU Regulatory Conformance
Please note that the above information is applicable to EU countries only.

easonable protection
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 r
residential installation. This equipment generates and can radiate radio frequency energy. If not installed and used in
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:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a different circuit to that of the receiver's outlet.
Consult the dealer or an experienced radio/TV technician for help.
Operation is subject to the following two conditions:
This device may not cause harmful interference.
This 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:
Do not remove the RF Exposure Label from the device.
User awareness instructions should accompany device when transferred to other users.
Do not use this device if the operational requirements described herein are not met.
Operating Instructions:
Transmit 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%

on-approved accessories
The antenna should be kept away from the face and
from the antenna. The antenna
less, is important because the radio generates measurable RF energy only when transmitting (in terms of measuring for standards compliance).
Keep 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
eyes.
When worn on the body, always place the radio in a Hytera-approved holder, holster, case, or body harness or
sult in exposure levels which exceed the FCC's occupational/controlled environmental RF exposure limits.
Use of non-approved antennas, batteries, and accessories causes the radio to exceed the FCC RF exposure guidelines.
Contact your local dealer for the optional accessories of the product.

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,

You cannot
communicate
with other
members.
The frequency or signaling may not match that of other
members.
Set your TX/RX frequency and signaling to the same as that of
other members.
The channel type (digital/analog) may be set
inconsistently. Make sure all members are on the same digital/analog channel.
You may be too far away from the group members. Move towards other members.

Troubleshooting
Phenomena Analysis Solution
Irrelevant
communication
or noise is heard
on the channel.
You may be interrupted by radios using the same
frequency. Change the frequency, or adjust the squelch level.
The radio may be set with no signaling. Set signaling for all member radios to avoid interference at the
same frequency.
The noise is too
loud.
You may be too far away from other members. Move towards other members.
You may locate in an unfavorable position. For example,
your communication may be blocked by high buildings
or frustrated in the underground areas.
Move to an open and at area, and restart the radio to try again.
You may suffer from external disturbance (such as
electromagnetic interference). Stay away from equipment that may cause interference.
