EXPLICIT DEFINITIONS
WORD DEFINITION
RWARNING!
CAUTION
NOTE
Personal injury, fire hazard or electric shock
may occur.
Equipment damage may occur.
Recommended for optimum use. No risk of
personal injury, fire or electric shock.
Icom, Icom Inc. and the logo are registered trademarks of Icom
Incorporated (Japan) in the United States, the United Kingdom, Ger-
many, France, Spain, Russia and/or other countries.

RWARNING RF EXPOSURE! This device emits
Radio Frequency (RF) energy. Extreme caution should be ob-
served when operating this device. If you have any questions re-
garding RF exposure and safety standards please refer to the
Federal Communications Commission Office of Engineering and
Technology’s report on Evaluating Compliance with FCC Guide-
lines for Human Radio frequency Electromagnetic Fields (OET
Bulletin 65)
RWARNING! NEVER connect the transceiver to an AC
outlet. This may pose a fire hazard or result in an electric shock.
RWARNING! NEVER operate the transceiver while dri-
ving a vehicle. Safe driving requires your full attention—anything
less may result in an accident.
NEVER connect the transceiver to a power source of more
than 16 V DC. This will ruin the transceiver.
NEVER connect the transceiver to a power source using re-
verse polarity. This will ruin the transceiver.
NEVER cut the DC power cable between the DC plug and
fuse holder. If an incorrect connection is made after cutting, the
transceiver may be damaged.
NEVER expose the transceiver to rain, snow or any liquids.
The transceiver may be damaged.
NEVER operate or touch the transceiver with wet hands. This
may result in an electric shock or ruin the transceiver.
NEVER place the transceiver where normal operation of the
vehicle may be hindered or where it could cause bodily injury.
NEVER let objects impede the operation of the cooling fan on
the rear panel.
DO NOT push the PTT when not actually desiring to transmit.
DO NOT allow children to play with any radio equipment con-
taining a transmitter.
During mobile operation, DO NOT operate the transceiver
without running the vehicle’s engine. When the transceiver’s
power is ON and your vehicle’s engine is OFF, the vehicle’s bat-
tery will soon become exhausted.
BE CAREFUL! The transceiver will become hot when op-
erating it continuously for long periods.
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).
AVOID the use of chemical agents such as benzine or alcohol
when cleaning, as they can damage the transceiver’s surfaces.
USE Icom microphones only (supplied or optional). Other man-
ufacturer’s microphones have different pin assignments and may
damage the transceiver if attached.

■Installation
DLocation
Select a location which can support the weight of the trans-
ceiver and does not interfere with driving in any way. We rec-
ommend the locations shown in the diagram below.
NEVER place the transceiver where normal operation of the
vehicle may be hindered or where it could cause bodily injury.
NEVER place the transceiver where air bag deployment may
be obstructed.
DO NOT place the transceiver where hot or cold air blows di-
rectly onto it.
AVOID placing the transceiver in direct sunlight.
DUsing the mounting bracket
➀Drill 4 holes where the mounting bracket is to be installed.
• Approx. 5.5–6 mm (1⁄4″) when using nuts; approx. 2–3 mm (1⁄8″)
when using self-tapping screws.
➁Insert the supplied screws, nuts and washers through the
mounting bracket and tighten.
➂Adjust the angle for the clearest view of the function dis-
play.

DBattery connection
☞NEVER connect the transceiver directly to a 24 V battery.
☞DO NOT use the cigarette lighter socket for power con-
nections. (See p. 5 for details)
Attach a rubber grommet when passing the DC power cable
through a metal plate to prevent short circuiting.
•CONNECTING TO A DC POWER SOURCE
•See p. 72 for fuse replacement.
DDC power supply connection
Use a 13.8 V DC power supply with at least 15 A capacity.
Make sure the ground terminal of the DC power supply is
grounded.

DAntenna installation
•Antenna location
To obtain maximum performance from the transceiver, select
a high-quality antenna and mount it in a good location. A non-
radial antenna should be used when using a magnetic mount.
•Antenna connector
The antenna uses a PL-259 connector.
•PL-259 CONNECTOR

jacket and soft solder.
wStrip the cable as shown

ter conductor.
eSlide the connector body

rScrew the coupling ring
onto the connector body.
(10 mm ≈3⁄8 in)
NOTE: There are many publications covering proper an-
tennas and their installation. Check with your local dealer
for more information and recommendations.
DConnecting a microphone
Connect a microphone to the eight-pin modular socket on the
front panel of the transceiver.

QUICK REFERENCE GUIDE
■Your first contact
Now that you have your IC-V8000 installed in your car or
shack, you are probably excited to get on the air. We would
like to take you through a few basic operation steps to make
your first “On The Air”an enjoyable experience.
1. Turning ON the transceiver
Before powering up your IC-V8000, you may want to make
sure the audio volume and squelch level controls are set in
9–10 o’clock positions.
Although you have purchased a brand new transceiver, some
settings may be changed from the factory defaults because
of the QC process. Resetting the CPU is necessary to start
from factory default.
➥While pushing [SET(LOCK)] and [MW(S.MW)], push
[PWR] for 1 sec. to reset the CPU.
2. Tune the desired frequency
The tuning dial will allow you to dial in the frequency you want
to operate. Pages 9 and 11 will instruct you on how to set the
tuning speed.
Using the HM-133V
You can directly enter the frequency with the HM-133V keypad.
We hope these pointers have been helpful. Now you
are ready to call CQ.
[EXAMPLE]: Setting frequency to 145.3625 MHz.

■Repeater operation
1. Setting duplex
Push [LOW(DUP)] for 1 sec. once or twice to select minus du-
plex or plus duplex.
•The USA and CSA versions have an auto repeater function, there-
fore, setting duplex is not required.
2. Repeater tone
Push [TONE(T-SCAN)] several times until “”appears, if the
repeater requires a subaudible to be accessed.
Using the HM-133V
Plus or minus duplex selection and the repeater tone setting
can be made easily via HM-133V.
Push [
DUP –7(TONE)] for minus duplex; [ DUP +8(TSQLS)]
for plus duplex selection, push [FUNC] then [
DUP –7(TONE)]
to turn the repeater tone ON.

■Programming memory
channels
The IC-V8000 has a total of 200 memory channels (including
6 scan edges and 1 call channel) for storing often used oper-
ating frequency, repeater settings, etc.
1. Setting a frequency
In VFO mode, set the desired operating frequency with re-
peater, tone and tuning steps, etc.
2. Selecting a memory channel
Momentarily push [MW(S.MW)], then rotate the tuning dial to
select the desired memory channel.
•“M”indicator and memory channel number blink.
3. Writing a memory channel
Push and hold [MW(S.MW)] for 1 sec. to program.
•3 beeps sound
•Memory channel number automatically increases when continuing
to push [MW(S.MW)] after programming.
Using the HM-133V
qIn VFO mode, set the desired operating frequency, includ-
ing offset direction, tone settings, etc.
