1、INSTRUCTION MANUAL This device complies with Part 15 of the FCC rules. Operation is sub- ject 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. DUA

2、L BAND FM TRANSCEIVER iT7H 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 trans

3、ceiver 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 op- eration. If you experience a ringing in your ears, reduce the volume level or discontinue use. NEVERconnect the trans

4、ceiver to an AC outlet or to a power source of more than 16 V DC. Such a connection will damage the transceiver. NEVERconnect 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 pro- t

5、ection against such accidents and the transceiver will be ruined. NEVERattempt to charge alkaline or dry cell batteries. Be- ware that external DC power connections will charge batteries inside the battery case. This will damage not only the battery case but also the transceiver. i IMPORTANT READ AL

6、L INSTRUCTIONS carefully and completely before using the transceiver. SAVE THIS INSTRUCTION MANUALThis instruction man- ual contains important operating instructions for the IC-T7H. EXPLICIT DEFINITIONS The explicit defi nitions below apply to this instruction manual. CAUTIONS WORDDEFINITION RWARNIN

7、G Personal injury, fi re hazard or electric shock may occur. CAUTION Equipment damage may occur. NOTE If disregarded, inconvenience only. No risk of personal injury, fi re or electric shock. The IC-T7H complies with essential requirements of the 89/336/EEC directive for Electromagnetic Compatibility

8、. This compliance is based on conformity with the ETSI specification ETS300 684 (EMC product standard for Commercially Available Amateur Radio Equipment). ii UNPACKING Accessories included with the transceiver:Qty.

9、d to the transceiver.1 Belt clip .1 Wall charger* .1 *Not supplied with battery case versions. Antenna for U.S.A. version differs from that shown above. DO NOT push the PTT when not actually desiring to trans- mit. DO NOT operate the transceiver near unshielded electrical blasting caps or in an expl

10、osive atmosphere. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below 10C (+14F) or above +60C (+140F). Place unit in a secure place to avoid inadvertent use by chil- dren. The use of non-Icom battery packs/chargers may impair transceiver performance and inv

11、alidate the warranty. Even when the transceiver power is OFF, a slight current still fl ows 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 dry cell batteries will become ex- hausted. For U.S.A. only CA

12、UTION: Changes or modifi cations to this device, not ex- pressly approved by Icom Inc., could void your authority to operate this device under FCC regulations.

Charge the battery pack before fi rst operating the transceive

36、r or when the battery pack becomes exhausted. *Optional for versions which come with the BP-170 BATTERY CASE. If you want to be able to charge the battery pack more than 300 times, the following points should be observed: 1. Avoid overcharging. The charging period should be less than 48 hours. 2. Us

37、e the battery until it becomes almost completely ex- hausted under normal conditions. We recommend battery charging just after transmitting becomes impossible. I Charging precautions NEVER attempt to charge dry cell batteries. This will cause internal liquid leakage and damage the battery case and t

38、ransceiver. NEVER connect two or more chargers at the same time. Charging may not occur under temperatures of 10C (50F) or over temperatures of 40C (104F). I About the battery pack D Operating period Depending on the attached battery pack, the operating period of the transceiver varies. Refer to p.

39、28 for battery pack spec- ifi cations. D Battery pack life If your battery pack seems to have no capacity even after being fully charged, completely discharge it by leaving the power ON overnight. Then, fully charge the battery pack again. If the battery pack still does not retain a charge (or very

40、little), a new battery pack must be purchased. Recycling information (U.S.A. only) The product that you purchased contains a rechargeable battery. The battery is recyclable. At the end of its useful life, under various state and local laws, it may be illegal to dispose of this battery into the munic

41、ipal waste stream. Call 1-800-8-BATTERY for battery recycling options in your area or contact your dealer.
