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:
z Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver.
z Connect the equipment into an outlet on a different circuit to that of the receiver's outlet.
To control your exposure and ensure compliance with the exposure limits,
z Consult the dealer or an experienced radio/TV technician for help.
Operation is subject to the following two conditions:
z This device may not cause harmful interference.
z 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 radio complies with the following RF energy exposure standards and guidelines:
z United States Federal Communications Commission, Code of Federal Regulations; 47 CFR § 1.1307, 1.1310
and 2.1093
z American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95.
1:2005; Canada RSS102 Issue 5 March 2015
z Institute of Electrical and Electronic Engineers (IEEE) C95.1:2005 Edition
RF Exposure Compliance and Control Guidelines and
Operating Instructions
always adhere to the following procedures.
Guidelines:
z
Do not remove the RF Exposure Label from the device.
z
User awareness instructions should accompany device when transferred to other users.
z
Do not use this device if the operational requirements described herein are not met.
Operating Instructions:
z
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% of the time, or less, is important because
the radio generates measurable RF energy only when transmitting (in terms of measuring for standards
compliance).
z
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 from the antenna. The antenna should be kept away from the face and
eyes.
z When worn on the body, always place the radio in a Hytera-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 RF exposure limits.
z Use of non-approved antennas, batteries, and accessories causes the radio to exceed the FCC RF exposure
guidelines.
z Contact your local dealer for the optional accessories of the product.
ISED Statement
The device has been tested and complies with SAR limits, users can obtain Canadian information on RF exposure
and compliance.
Après examen de ce matériel aux conformité aux limites DAS et/ou aux limites d’intensité de champ RF, les
utilisateurs peuvent sur l’exposition aux radiofréquences et la conformité and compliance d’acquérir les
informations correspondantes
This device complies with ISED license-exempt RSS standard(s). Operation is subject to the following two
conditions:
z
This device may not cause harmful interference.
z
This device must accept any interference received, including interference that may cause undesired operation.
