DP770 Instruction Manual                2/27    Safety Before using this radio, read this operating instruction carefully for safe and convenient usage. This product can only be maintained by the professional technicians. Do not disassemble the radio by yourself.   To avoid of the problems caused by electromagnetic interference or electromagnetic compatibility, turn off the radio in any facilities where posted notices instruct you to do so, such as hospital and other health care facilities. And when on board an aircraft, turn off the radio if instructed to do so too. In the vehicle with an air bag, do not place the radio in the area over an air bag or in the air bag deployment area.   Turn off the radio before entering any area with a potentially explosive atmosphere or blasting caps. Do not operate the radio, disassemble or charge the battery in the potentially flammable and explosive atmosphere (such as gas station, coal gas station, etc.).   Do not place the radio under the direct sunlight or near the area with heating devices.   Do not place the radio in the area with great dust, moisture or drips, or on the unstable surface.   Contact us or your local dealer for help if you want to re-develop or modify the radio. Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into contact with your skin, a minor burn can result.   Make sure the antenna is correctly installed when using. The radio without antenna may cause damage in the process of transmission. Keep the radio vertically and away from your mouth about 5cm in the process of transmission.   When worn on your body, make sure the antenna is at least 2.5cm away from your body in the process of transmission.    Battery  All batteries can cause property damage and/or bodily injury, such as burns, if a conductive material such as jewelry, keys, or beaded chains touches exposed terminals. The conductive material may complete an electrical circuit (short circuit) and become quite hot. Excessive care in handling any charged battery, particular when placing it inside a pocket, purse, or other container with metal objects. To reduce the potentially damage, do not expose the battery in the fire, or disassemble and extrude the battery.    The maximum ambient temperature around the adapter or transformer for the charger should not exceed 40℃ (104℉).  Turn off the radio when charging. If not, the battery’s capacity will be affected.  Do not insert the battery pack into the charger when charging is not necessary. The continuous charging will shorten the battery’s lifetime. Do not use the charger as the pedestal for the radio.
DP770 Instruction Manual                3/27 To realize the best performance of the battery, change the battery once a year.    This device complies with part 15 of the FCC Rules. 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.    Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.    Your radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as "Occupational Use Only" meaning it must be used only during the course of employment by individuals aware of the hazards, and the ways to minimize such hazards. This radio is NOT intended for use by the "General Population"in an uncontrolled environment. This radio has been tested and complies with the FCC RF exposure limits for "ccupational Use Only" In addition, your Kirisun Communications Co.,Ltd radio complies with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for exposure to humans:   1. FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.   2. American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.   3. American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields- RF and Microwave.   4. The following accessories are authorized for use with this product. Use of accessories other than those (listed in the instruction) specified may result in RF exposure levels exceed the FCC requirements for wireless RF exposure.  To ensure that your expose to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines: 1. DO NOT operate the radio without a proper antenna attached, as this may damaged the radio and may also cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio by the manufacturer or antenna specifically authorized by the manufacturer for use with this radio. 2. DO NOT transmits for more than 50% of total radio use time (“50% duty cycle”). Transmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio is transmitting when the “TX indicator” lights red. You can cause the radio to transmit by pressing the “PTT” switch. 3. ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when transmitting and only use the Kirisun belt-clip which is listed in instructions when attaching the radio to your belt, etc., to ensure FCC RF exposure compliance requirements are not exceeded. To provide the recipients of your transmission the best sound quality, hold the antenna at least 5 cm (2 inches) from your mouth, and slightly off to one side. The information listed above provides the user with
DP770 Instruction Manual                4/27 the information needed to make him or her aware of RF exposure, and what to do to as*sure that this radio operates with the FCC RF exposure limits of this radio. Electromagnetic Interference/Compatibility During transmissions, your Kirisun radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals, aircraft, and blasting sites. Occupational/Controlled Use The radio transmitter is used in situations in which persons are exposed as consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure.
