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:
lReorient or relocate the receiving antenna. Increase
the separation between the equipment and receiver.
lConnect the equipment into an outlet on a different
circuit to that of the receiver's outlet.
lConsult the dealer or an experienced radio/TV
technician for help.
Operation is subject to the following two conditions:
lThis device may not cause harmful interference.
lThis 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
The radio complies with the following RF energy
exposure standards and guidelines:
lUnited States Federal Communications Commission,
Code of Federal Regulations; 47 CFR § 1.1307,
1.1310 and 2.1093
lAmerican National Standards Institute
(ANSI)/Institute of Electrical and Electronic
Engineers (IEEE) C95. 1:2005; Canada RSS102 Issue
5 March 2015
lInstitute 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 environmental exposure limits,
always adhere to the following procedures.
Guidelines:
lDo not remove the RF Exposure Label from the
device.
lUser awareness instructions should accompany
device when transferred to other users.
lDo not use this device if the operational requirements
described herein are not met.
Operating Instructions:

lTransmit no more than the rated duty factor of 50%
of the time. To transmit (talk), press 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).
lKeep 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.
lWhen worn on the body, always place the radio in an
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.
lUse of non- approved antennas, batteries, and
accessories causes the radio to exceed the FCC RF
exposure guidelines.
lContact your local dealer for the product's optional
accessories.
EU Regulatory Conformance
As certified by the qualified laboratory, the product is in
compliance with the essential requirements and other
relevant provisions of 2014/53/EU.
Please note that the above information is applicable to EU
countries only.
