INSTRUCTION MANUAL 144 MHz FM TRANSCEIVER iT2H 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. IMPORTANT READ ALL INSTRUCTIONS pletely before using the transceiver. carefully and com- CAUTIONS RWARNING! 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 in) away from the lips and the transceiver is vertical. SAVE THIS INSTRUCTION MANUAL--This instruction manual contains important operating instructions for the IC-T2H. EXPLICIT DEFINITIONS The explicit definitions below apply to this instruction manual. DEFINITION Personal injury, fire hazard or electric RWARNING shock may occur. CAUTION NOTE Equipment damage may occur. If disregarded, inconvenience only. No risk of personal injury, fire or electric shock. Versions of the IC-T2H which display the "CE" symbol on the serial number seal, comply with the ETSI specification prETS300 684 (EMC product standard for Commercially Available Amateur Radio Equipment). 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 an AC outlet or to a power source of more than 16 V DC. Such a connection will damage the transceiver. 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, 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. Beware that external DC power connections will charge batteries inside the battery case. This will damage not only the battery case but also the transceiver. WORD ii SUPPLIED ACCESSORIES DO NOT push the PTT when not actually desiring to transmit. Place unit in a secure place to avoid inadvertent use by children. Accessories included with the transceiver: 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 (+14°F) or above +60°C (+140°F). 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. For USA only: Caution: Changes or modifications to this transceiver, not expressly approved by Icom Inc., could void your authority to operate this transceiver under FCC regulations.
