Y4GCU600-2Two Way Radio

Instruction Manual CU600- Two Way Radio Notice to the User: · Please read this instruction manual before operating this radio. · It’s prohibited to use the radio or charge it at any area with a potentially explosive atmosphere (where th e air contains gas, dust and smog, etc.), such as while taking on fuel, or while parking at a gasoline service station; or any area where radio communication is prohibited (such as a hospital or a airport.) · It’s prohibited to operate the radio without permissi on at the areas where the government laws prohibit radio communication. · Please don't expose the radio to direct sunlight for a long time; don't place the radio near any heatin g devices, either. · Please don't put the radio in extremely dusty, m oist or dabbling places; don’t place it on any unstable surfaces, either. · If you want to develop or remodify the radio · Refer service to the well-trained professional technicians only and do not disassemble or assemb le the radio. SHENZHEN COVALUE COMMUNICATIONS Co., Ltd. 1 W AR N IN G Your radio generates RF electromagnetic en- ergy 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 uncon- trolled environment. This radio has been tested and complies with the FCC RF ex- posure limits for “Occupational Use Only”. In addition, your radio complies with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels and eval- uation of such levels for exposure to humans: • FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluat- ing Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. • A me rican 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. • Ame rican National Standards Institute (C95.3-1992), IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields– RF and Microwave. • The following accessories are authorized for use with this product. Use of accessories other than those specified may result in RF exposure levels exceeding the FCC requirements for wireless RF exposure.; Belt Clip, Rechargeable Li-Ion Battery Pack, Charger. C AU TIO N To ensure that your expose to RF electromag- netic energy is within the FCC allowable lim- its for occupational use, always adhere to the following guidelines: • DO NOT operate the radio without a proper antenna at- tached, as this may damaged the radio and may also exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio or antenna specifically authorized for use with this radio. • DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”). “50% duty cycle” is also applicable to PSTN (Public Switched Telephone Network) mode and VOX Mode .Tr ansmitting 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. • ALWAYS keep the antenna at least 2.5 cm (1 in.) away from the body when transmitting and only use the Icom belt-clips listed on p. 24 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 in.) from your mouth, and slightly off to one side. The information listed above provides the user with the informa- tion needed to make him or her aware of RF exposure, and what to do to assure that this radio operates with the FCC RF expo- sure limits of this radio. 25 SAFETY TRAINING INFORMATION CONTENTS ■ Unpacking and Checking the Equipment Supplied Accessories ■ Preparat ion Char ging the Battery Installing/Removing the Battery Pack Installing the Antenna Installing the Optional Speaker/Microphone Installing/Removing the Belt Clip ■ Radio Overview ■ Basic Operations ■ Programmable Button Function ■ VOX (Voice Operated Transmission) ■ Wired Cloning Mode ■ Radio Setting TOT (Time-out Timer) Battery Save Low Power Warning Channel Annunciation CTCSS/DCS ■ User Template RX Squelch Mode DTMF 5-Tone Signaling ■ Troubleshooting ■ Settings 2 ■ Unpacking and Checking the Equipment Unpack the radio carefully.
