FCC StatementThis equipment has been tested and found to comply withthe limits for a Class B digital device, pursuant to part 15of FCC Rules. These limits are designed to providereasonable protection against harmful interference in aresidential installation. This equipment generates and canradiate radio frequency energy. If not installed and usedin accordance with the instructions, it may cause harmfulinterference to radio communications. However, there isno guarantee that interference will not occur in aparticular installation. Verification of harmfulinterference by this equipment to radio or televisionreception can be determined by turning it off and then on.The user is encouraged to try to correct the interferenceby one or more of the following measures:

l Reorient or relocate the receiving antenna. Increasethe separation between the equipment and receiver.

l Connect the equipment into an outlet on a differentcircuit to that of the receiver's outlet.

l Consult the dealer or an experienced radio/TVtechnician for help.

Operation is subject to the following two conditions:

l This device may not cause harmful interference.l This device must accept any interference received,

including interference that may cause undesiredoperation.

Note: Changes or modifications to this unit not expresslyapproved by the party responsible for compliance couldvoid the user's authority to operate the equipment.

Compliance with RF ExposureStandardsThe radio complies with the following RF energyexposure standards and guidelines:

l United States Federal Communications Commission,Code of Federal Regulations; 47 CFR § 1.1307,1.1310 and 2.1093

l American National Standards Institute(ANSI)/Institute of Electrical and ElectronicEngineers (IEEE) C95. 1:2005; Canada RSS102 Issue5 March 2015

l Institute of Electrical and Electronic Engineers(IEEE) C95.1:2005 Edition

RF Exposure Compliance andControl Guidelines and OperatingInstructionsTo control your exposure and ensure compliance with theoccupational/controlled environmental exposure limits,always adhere to the following procedures.

Guidelines:

l Do not remove the RF Exposure Label from thedevice.

l User awareness instructions should accompanydevice when transferred to other users.

l Do not use this device if the operational requirementsdescribed herein are not met.

Operating Instructions:

l Transmit 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 importantbecause the radio generates measurable RF energyonly when transmitting (in terms of measuring forstandards compliance).

l Keep the radio unit at least 2.5 cm away from theface. Keeping the radio at the proper distance isimportant as RF exposure decreases with distancefrom the antenna. The antenna should be kept awayfrom the face and eyes.

l When worn on the body, always place the radio in anapproved holder, holster, case, or body harness or byuse of the correct clip for this product. Use of non-approved accessories may result in exposure levelswhich exceed the FCC's occupational/controlledenvironmental RF exposure limits.

l Use of non- approved antennas, batteries, andaccessories causes the radio to exceed the FCC RFexposure guidelines.

l Contact your local dealer for the product's optionalaccessories.

IC StatementThe device has been tested and complies with SAR limits,users can obtain Canadian information on RF exposureand compliance.
