RF Radiation Information
RF Radiation Profile
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 fields.
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;
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 no more than 50% of the
time and always adhere to the following procedures:
RF energy will be generated only when the radio is transmitting.
If you are not using a body-worn accessory and are not using the radio in the
intended use position in front of the face, then ensure the antenna and the radio
are kept at least 2.5 cm (one inch) from the body when transmitting. Keeping the
radio at the proper distance is important because RF exposures decrease with

4
increasing distance from the antenna.
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 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:
● Reorient or relocate the receiving antenna. Increase the separation between the
equipment and receiver.
● Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
● Consult the dealer or an experienced radio/TV technician for help
Operation is subject to the following two conditions: 1. This device may not cause harmful
interference, and 2. 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.”
Compliance with RF Exposure Standards
Hytera’s 2-way radio complies with the following RF energy exposure standards and
guidelines:
• United States Federal Communications Commission, Code of Federal Regulations; 47
CFR §§ 1.1307, 1.1310 and 2.1093
• 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
RF Exposure Compliance and Control Guidelines and
Operating Instructions
To control your exposure and ensure compliance with the occupational/controlled
environment 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.

5
• 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) button. To receive calls, release the PTT button. Transmitting
50 % of the time, or less, is important because this radio generates measurable RF
energy exposure only when transmitting (in terms of measuring for standards
compliance).
• Hold the radio in a vertical position in front of face with the microphone (and the other
parts of the radio, including the antenna) at least one inch (2.5 cm) away from the nose.
Keeping the radio at the proper distance is important because RF exposures decrease
with distance from the antenna. Antenna should be kept away from eyes.
• When worn on the body, always place the radio in a Hytera’s approved clip, holder,
holster, case, or body harness for this product. Using approved body-worn accessories is
important because the use of Hytera’s or other manufacturer’s non-approved accessories
may result in exposure levels, which exceed the FCC’s occupational/controlled
environment RF exposure limits.
• If you are not using a body-worn accessory and are not using the radio in the intended
use position in front of the face, then ensure the antenna and the radio are kept at least
2.5 cm (one inch) from the body when transmitting. Keeping the radio at the proper
distance is important because RF exposures decrease with increasing distance from the
antenna.
• Use only manufacturer’s name approved supplied or replacement antennas, batteries,
and accessories. Use of non-manufacturer-name approved antennas, batteries, and
accessories may exceed the FCC RF exposure guidelines.
•For a list of Hytera’s approved accessories (see the user manual), or (visit the following
website which lists approved accessories: http: add website address), or(The
manufacturer should include the appropriate bracketed item{s} in the manual.)
• For a list of Hytera’s approved accessories (see the user manual), or (visit the following
website which lists approved accessories: www.hytera.cn

the PTT key.

19
Functions and Operations
Adjust Power Level
With this feature, you may switch power levels quickly. Generally, we recommend you to adopt low power
for battery saving. However, if you cannot communicate with radios located at a distant place with low
power, please select high power.
Operation:
Press the programmed Adjust Power Level key to switch between high power and low power (from low
power to high power: a high-pitched tone sounds; from high power to low power: a low-pitched tone
sounds).
Scan
This feature allows you to listen to communication activities on other channels so that you can keep a
close track of your team members.
Operation:
1. To enable the feature, press the programmed Scan key in standby mode (a high-pitched tone
sounds); or
Switch to a channel on which the feature “Auto Scan” is enabled via the programming software.
2. After the feature is enabled, your radio will scan according to the scan list set for the channel on
which scanning starts. The scanning process is as follows:
During scanning, the LED flashes orange.
When activities are detected on a channel, the radio will stay on the channel to receive current
activities, and the LED glows green.
If you don’t want to hear activities on the channel, press the programmed Nuisance Temporary
Delete key to remove the channel from the scan list temporarily.
If you want to continue staying on the channel, press the programmed Monitor or Squelch Off
key during scan stay.
3. To exit the scanning process, press the programmed Scan key again (a low-pitched tone sounds).
