IC-T81A/E Manual 98.12.16 4:39 PM Page A (1,1) INSTRUCTION MANUAL MULTIBAND FM TRANSCEIVER iT81A/E 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. IC-T81A/E Manual 98.12.16 4:39 PM Page ii (1,1) IMPORTANT CAUTIONS READ A L L INSTRUCTIONS carefully and com-
pletely before using the transceiver. S AVE THIS INSTRUCTION MANUALThis in-
struction manual contains important operating instructions for the IC-T81A/E. EXPLICIT DEFINITIONS The explicit denitions below apply to this instruction manual. Versions of the IC-T81A/E which display the CE sym-
bol on the serial number seal, comply with the ETSI specification ETS300 684 (EMC product standard for Commercially Available Amateur Radio Equipment). ii RWARNING! NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the b o d y, especially the face or eyes, while transmitting. T h e 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. 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 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. 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. IC-T81A/E Manual 98.12.16 4:39 PM Page iii (1,1) SUPPLIED ACCESSORIES Accessories included with the transceiver:

cludes rechargeable Ni-MH batteries and can be charged ap-
prox. 300 times. Charge the battery pack before first operating the transceiver or when the battery pack becomes exhausted.
*Optional for versions which come with the BP-197 BATTERY CASE. If you want to get the longest life out of your battery pack
(300+ charges), the following points should be observed:
1. Avoid overcharging. The charging period should be less than 15 hours. 2. Use the battery until it becomes completely exhausted under normal conditions. We recommend battery charging just after transmitting becomes impossible. n Charging precautions NEVER attempt to charge alkaline batteries. This will cause internal liquid leakage and damage the battery case and transceiver. 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). 6 n About battery packs D Operating period Depending on attached battery pack, the operating period of the transceiver varies. When the approx. voltage of battery packs BP-198, BP-199 or BP-200 falls to 4, 5 or 8 V, respec-
tively, charging is necessary. Refer to p. 33 for operating pe-
riod details. D Battery 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 little), a new battery pack must be purchased.
+ NOTE: When using a battery pack for the rst time or after long periods of inactivity between charges (approx. 2 months or more), the battery pack will not be able to retain a full charge immediately. Subsequent charge/discharge cycles will eventually bring the battery pack up to full charge capacity. IC-T81A/E Manual 98.12.16 4:39 PM Page 7 (1,1) BATTERY PACKS AND CHARGING 3 Charging periods: 1 hour (w/BP-198 or BP-199) 1.5 hours (w/BP-200) n Charging connections D Regular charging Attach the sup-
plied or optional battery pack;

nel for each bandVHF, UHF, 50 MHz and 1200 MHz). Note that memory channels are not grouped according to band. In other words, a given memory channel can be programmed with either a VHF frequency, a UHF frequency, a 50 MHz fre-
quency or a 1200 MHz frequency. This is not the case with call channels. Call channels are band specic. The following can be programmed into memory/call channels:
Operating frequency Duplex direction with an offset frequency (pgs. 15, 16) Subaudible tone encoder or tone squelch on/off with a tone
