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 modications 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 portable 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. 1:2005; Canada RSS102 Issue
5 March 2015.
●Institute of Electrical and Electronic Engineers (IEEE) C95.1:2005
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.
●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.
●Contact your local dealer for the optional accessories of the product.
IC Statement

informations correspondantes
This device complies with Industry Canada license-exempt RSS
standard(s). Operation is subject to the following two conditions:

Troubleshooting
Phenomena Analysis Solution
The radio cannot be
turned on.
The battery may be installed improperly. Remove and reattach the battery.
The battery power may run out. Recharge or replace the battery.
The battery may suffer from poor contact caused by dirtied
or damaged battery contacts. Clean the battery contacts or replace the battery.
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 get loose or may be installed improperly. Turn off the radio, and remove and reattach the antenna.
The speaker may be blocked. Clean the surface of the speaker.
You cannot
communicate
with other group
members.
The frequency or signaling may be inconsistent with that of
other members.
Set your TX/RX frequency and signaling to the same as
those of other members.
The channel type (digital or analog) may be set
inconsistently.
Make sure all members are on the same digital or analog
channel.
You may be too far away from other members. Move towards other members.
Irrelevant voices 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 in analog mode may be set with no signaling. Set signaling for all radios operating at the same frequency
to avoid interference.
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.
If the above solutions cannot x your problems, or you may have some other queries, please contact us or your local dealer for more technical support.
