Preface Thanks for your favor in our product. This manual is helpful for you to quickly know how to use the product. This manual is applicable to the following product: PD36XUc Digital Portable Radio (X may represent 0,2, 5, 6 or 8)

 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 not more than 50% of the time and always adhere to the following procedures:  RF energy will be generated only when the radio is transmitting. The radio must be 2.5 centimeters away from human body when transmitting. 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. • 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 IC statement

The device has been tested and compliance 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 EU Regulatory Conformance As certified by the qualified laboratory, the product is in compliance with the essential requirements and other relevant provisions of the Directive 1999/5/EC.
