harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
IMPORTANT
WORD DEFINITION
RWARNING
Personal injury, fire hazard or electric
shock may occur.
CAUTION
Equipment damage may occur.
NOTE
If disregarded, inconvenience only. No risk
of personal injury, fire or electric shoc
k.
CAUTIONS
READ ALL INSTRUCTIONS carefully and com-
pletely before using the transceiver.
SAVE THIS INSTRUCTION MANUAL—This in-
struction manual contains important operating instructions for
the IC-T81A/E.
EXPLICIT DEFINITIONS
The explicit definitions below apply to this instruction manual.
Versions of the IC-T81A/E which display the “CE” symbol
ii
on the serial number seal, comply with the European har-
monised standard ETS300 684 (EMC product standard
for Commercially Available Amateur Radio Equipment).
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.
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. 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.

BATTERY PACKS AND CHARGING
■ Battery pack charging
The supplied* BP-198, BP-199 or BP-200
cludes rechargeable Ni-MH batteries and can be charged approx. 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
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.
BATTERY PACK
BATTERY CASE
in-
.
■ 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.
■ 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, respectively, charging is necessary. Refer to p. 33 for operating period 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 first 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.
Charging may not occur under temperatures of 10°C (50°F)
or over temperatures of 40°C (104°F).

MEMORY/CALL PROGRAMMING
■ General
The transceiver has 124 memory channels (100 regular, 10
pairs of scan edge channels for mixed bands and 1 call channel for each band—VHF, 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 frequency or a 1200 MHz frequency. This is not the case with
call channels. Call channels are band specific.
The following can be programmed into memory/call channels:
• Operating frequency
• Duplex direction with an offset frequency (p. 16)
• Subaudible tone encoder or tone squelch on/off with a tone
(CTCSS) frequency (pgs. 16, 25)
• Mode—AM, FM, etc. (p. 14)
• Skip information* (p. 23)
*Except for scan edge memory channels and call channels.
☞ NOTE:
➥ Memory channels can be assigned names (of up to 6
characters).
➥ When memory names are assigned, each push of [MR]
toggles between frequency and name indication.

“T” flashes: the matched tone is stored as a repeater tone.
• When in memory mode, the decoded tone frequency is stored
temporarily—changing memory channels or selecting VFO mode
erases the matched tone.
•“CT” appears during tone scan when the tone squelch is acti-
vated; “rT” appears when the tone squelch is not activated.

☞ NOTE:DO NOT push the [PTT] on
the slave transceiver during
cloning. This will cause a cloning
error.
When the display at right appears, a cloning error has occurred.
In such a case, memory contents return to their default settings and both transceivers automatically enter VFO mode.
Cloning must then be repeated.
If your transceiver seems to be malfunctioning, please check
the following points before sending it to a service center.

PROBLEM
No power comes on.
Transmitting is impossible.
Frequency cannot be set.
Scan does not function.
[
Y] or [Z] keys do not
function when using the
optional HM-75A.
Squelch does not open for
received signals.
Some memory channels
cannot be selected.
RIT/VXO offset cannot be
adjusted.
Cannot transmit on the 50
MHz band.
POSSIBLE CAUSE
• The battery is exhausted.
(A slight current flows in the circuits even when the
power is off.)
• The battery is exhausted.
• Memory (call) mode is selected.
• The lock function is activated.
• The same frequencies are programmed into XA
and XB (a pair of scan edges).
• Only CH00 is programmed; or, all other memory
channels are set as skip channels.
• Memory channels 00 and/or 01 are not programmed and simple mode is selected.
• Tone squelch is activated.
• Some memories have been cleared.
• RIT/VXO function has not been activated or the
1200 MHz band is not selected.
• AM mode has been set for the 50 MHz band.
SOLUTION
• Charge the battery pack or place new dry cell batteries in the battery case.
(Remove the battery pack if you will not be using the trans-
ceiver for a long time.)
• Charge the batteries or place new dry cells in the
battery case.
• Push [VFO] to select VFO mode.
