PRECAUTIONS R DANGER! NEVER short the terminals of the battery pack. R DANGER! Use and charge only specified Icom bat- tery packs with Icom radios or Icom chargers. Only Icom battery packs are tested and approved for use with Icom radios or charged with Icom chargers. Using third-party or counterfeit battery packs or chargers may cause smoke, fire, or cause the battery to burst. CAUTION: MAKE SURE the flexible antenna, bat- tery pack and jack cover are securely attached to the transceiver, and that the antenna and battery pack are dry before attachment. Exposing the inside of the transceiver to dust or water will result in serious damage to the transceiver. DO NOT operate the transceiver near unshielded electri- cal blasti­ng caps or in an explosive atmosphere. DO NOT push [PTT] when not actually intending to transmit. R WARNING! NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the body, especially the face or eyes, while transmitting. The transceiver will perform best if the microphone is 5 to 10 cm (2 to 4 inches) away from the lips and the transceiver is vertical. R WARNING! NEVER operate the transceiver with a headset or other audio accessories at high volume levels. Hearing experts advise against continuous high volume operation. If you experience a ringing in your ears, reduce the volume level or discontinue use. R WARNING! NEVER operate the transceiver while driving a vehicle. Safe driving requires your full attention- anything less may result in an accident. DO NOT use or place the transceiver in direct sunlight or in areas with temperatures below -30°C (-22°F) or above +60°C (+140°F). The basic operations, transmission and reception of the transceiver are guaranteed within the specified operating temperature range. However, the LCD display may not be operate correctly, or show an indication in the case of long hours of operation, or after being placed in extremely cold areas. DO NOT modify the transceiver. The transceiver warranty does not cover any problems caused by unauthorized modification. DO NOT use harsh solvents such as benzine or alcohol when cleaning, as they will damage the transceiver surfaces. BE CAREFUL! The transceiver will become hot when operating it continuously for long periods of time. ii
