INSTRUCTION MANUAL VHF TRANSCEIVER iT3 H FOREWORD Thank you for purchasing the IC-T3H FM transceiver. This transceiver is designed for those who require quality, performance and outstanding reliability under the most demanding conditions. IMPORTANT READ ALL INSTRUCTIONS carefully and completely before using the transceiver. SAVE THIS INSTRUCTION MANUAL­ This instruction manual contains important operating instructions for the transceiver. EXPLICIT DEFINITIONS The explicit definitions below apply to this instruction manual. WORD R WARING CAUTION NOTE DEFINITION Personal injury, fire hazard or electric shock may occur. Equipment damage may occur. If disregarded, inconvenience only. No risk of personal injury, fire or electric shock.

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 away from the lips and the transceiver is vertical. RWARNING! 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 or discontinue use. NEVER connect the transceiver to a power source that is DC fused at more than 5 A. Accidental reverse connection will be protected by this fuse, but higher fuse values will not give any protection against such accidents and the transceiver will be ruined. NEVER attempt to charge alkaline or dry cell batteries. Be aware that external DC power connections will charge batteries inside the battery case. This will damage not only the battery case but also the transceiver. DO NOT push the PTT when not actually desiring to transmit. Place the unit in a secure place to avoid inadvertent use by children. iii DO NOT operate the transceiver near unshielded electrical blasting caps or in an explosive atmosphere. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below ­10°C or above +60°C. The use of non-Icom battery packs/chargers may impair transceiver performance and invalidate the warranty. Even when the transceiver power is OFF, a slight current still flows in the circuits. Remove the battery pack or case from the transceiver when not using it for a long time. Otherwise, the battery pack or installed Ni-Cd batteries will become exhausted. iv TABLE OF CONTENTS FOREWORD...........................................................................i IMPORTANT
