FOREWORD

READ ALL INSTRUCTIONS carefully and completely

before using the transceiver.

SA VE THIS INSTRUCTION MANUAL — This in-

struction manual contains important operating instructions for
the IC-2800H.

EXPLICIT DEFINITIONS

The explicit definitions below apply to this instruction manual.

CA UTIONS

RWARNING! NEVER connect the tr ansceiver to an AC

outlet. This may pose a fire hazard or result in an electric
shock.

RWARNING! NEVER oper ate the transceiv er while dri-

ving a vehicle. Safe driving requires your full attention—any­thing less may result in an accident.

RWARNING! HIGH VOLTAGE! NEVER disassem-

ble the remote controller .There is a high voltage circuit inside.

NEVER connect the transceiver to a power source of more

than 16 V DC or using reverse 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 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 trans-

mit.

WORD

R

WARNING

CAUTION

NOTE

DEFINITION

Personal injury, fire hazard or electric
shock may occur.

If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.

Equipment damage may occur.

Versions of the IC-2800H which display the “CE” symbol on the se­rial number seal comply with the European harmonised standard
ETS300 684 (EMC product standard for Commercially Available
Amateur Radio Equipment).

ii

DO NOT operate the transceiver near unshielded electrical

blasting caps or in an explosive atmosphere.
During mobile operation,

DO NOT operate the transceiver

without running the vehicle’s engine .When transceiv er po w er
is ON and your vehicle’s engine is OFF, the vehicle’s battery
will soon become exhausted.

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).

AVOIDthe use of chemical agents such as benzine or alco-

hol when cleaning, as they can damage the transceiver’s sur­faces.

Place unit in a secure place to avoid inadvertent use by chil­dren.

BE CAREFUL! The transceiver will become hot when op-

erating it continuously for long periods.

USE Icom microphones only (supplied or optional). Other

manufacturer’s microphones have different pin assignments
and may damage the transceiver if attached.

For LCD display

DO NOT press the LCD screen. Excessive pressure may

cause permanent damage to the LCD.

DO NOT tap or scratch the LCD using sharp objects.
BE CAREFUL when cleaning the LCD. Dust can easily

scratch the surface.
LCDs are produced using high-density manufacturing tech-

nology resulting in 99.98% active dots, however, up to 0.02%
of the dots may be non-active and/or continuously activ e .This
is normal and does not indicate LCD malfunction.

Uneven areas may be displayed depending on display con­tents in some cases.

After displaying the same screen continuously for long peri­ods, image ‘b urn-in’may occur .In such cases, turn the power
OFF and discontinue operation for at least 24 hours.

For U.S.A. only

CAUTION:Changes or modifications to this device, not ex-

pressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.

ANTENNA INFORMATION

For radio communications, the antenna is of critical impor­tance, along with output power and sensitivity. The trans­ceiver accepts a 50 Ω antenna and less than 1.5 : 1 of
Voltage Standing Wave Ratio (VSWR). High SWR values
not only may damage the transceiv er but also lead to TVI or
BCI problems.

INSTALLATION

■ Location

Select a location which can support the weight of the trans­ceiver and does not interfere with driving in any way. We rec­ommend the locations shown in the diagram below.

NEVER place the transceiver or remote controller where nor­mal operation of the vehicle may be hindered or where it
could cause bodily injury.
NEVER place the transceiver or remote controller where air
bag deployment may be obstructed.
DO NOT place the transceiver or remote controller where hot
or cold air blows directly onto it.
AVOID placing the transceiver or remote controller in direct
sunlight.

•EXAMPLE INSTALLATION LOCATIONS

■ Mounting with the mounting

bracket

q Drill 4 holes where the mounting bracket is to be installed.

•Approx.5.5–6 mm (3⁄16˝) when using nuts;approx. 2–3 mm (1⁄16˝)
when using self-tapping screws.

w Insert the supplied screws, nuts and washers through the

mounting bracket and tighten.

e Adjust the angle, if desired.

■ Battery connection

NEVER connect the transceiver directly to a 24 V battery.
DO NOT use the cigarette lighter socket for power con-

nections.

Attach a rubber grommet when passing the DC power cable
through a metal plate to prevent short circuits.

FREQUENCY SETTING

■ Preparation

D Turning power ON/OFF

Before operating the transceiver f or the first time it’s a good
idea to reset the transceiver’s CPU.This will ensure that all
transceiver settings are at their defaults.See p.75 for CPU
resetting details.

➥Push [POWER] for 2 sec.to turn power ON or OFF.

D Operating band

The transceiver can receive 144 MHz and 430(440) MHz
band signals simultaneously. To activate all functions or to
change frequency via the microphone, you must designate
one band as the main band. The transceiver can transmit a
signal on the main band only.

➥Push either [MAIN] to select the desired transmit band.

•“Q” indicator shows the selected band as the main band.

➥Push [BAND] to select the desired operating

band.

•“Q” indicator shows the selected band as the
main band.

D VFO and memory modes

The transceiver has 2 basic operating modes:VFO mode and
memory mode. Select VFO mode first to set an operating fre­quency.

➥Push [V/M

H

] to select VFO mode when the transceiver is

not in VFO mode.

• If VFO mode is already selected,
the digits below 100* kHz disap­pear. In this case, push [V/MH]
again (or push twice or 3 times de­pending on version).
* The digits below 1 or 10 MHz dis-

appear for some versions.

➥Push [VFO] to select VFO mode.
➥Push [MR] to select memory mode.

■ Lock functions

To prevent accidental frequency changes and unnecessary
function access, use the lock function.The transceiver and
HM-98 have 2 diff erent lock functions.

D Frequency lock

This function locks the tuning dials and switches electronically
and also locks the microphone switches.

➥Push [CHG/L] for 2 sec.to toggle the frequency lock func-

tion ON and OFF.

• [CHG/L], [MAIN], [MONI], [VOL], [SQL], [PTT] and [BAND] can
be used while the frequency lock function is in use. Also,
TONE-1, TONE-2, DTMF tones or DTMF memory contents can
be transmitted from the HM-98 microphone.

➥Push [(VFO) LOCK] for 2 sec. to toggle the func-

tion ON and OFF.

D Microphone keypad lock

This function locks the HM-98 microphone keypad.

➥Push [FUNC] then [16KEY LOCK] to tog-

gle the microphone keypad lock function
ON and OFF.

• [PTT] and the 7 keys on the upper half of the
microphone can be used.

•All switches on the transceiver can be used.

•The keypad lock function is released when the
transceiver power is turned OFF then ON
again.

•Push [CHG/L] if [V/MH] is not displayed.

w Rotate desired band’s [DIAL] to change the frequency.

• The frequency changes according to the selected tuning steps.
See the next page for selecting the tuning step.

D 1 MHz tuning step

Push the selected band’s [V/MH] to select 1 MHz tuning step.
Push [V/M

H

] again to return to the previous tuning step.

D 10 MHz and 1 MHz tuning steps

Push the selected band’s [V/MH] once or twice to select 10
MHz or 1 MHz tuning step, respectively. Push [V/M

H

] once or

twice to return to the previous tuning step.

Some versions do not have the 10 MHz tuning step.

■ Using the [Y]/[Z] keys

q Push [BAND] to select the desired band.
w Push [VFO] to select the VFO mode.
e Push [Y] or [Z] to select the desired frequency.

• The frequency changes according to the selected
tuning steps.(p. 21)

•Pushing [Y] or [Z] for more than 0.5 sec.activates
a scan. If this happens, push [Y] or [Z] again to
cancel the scan.

1 MHz or 10 MHz steps cannot be used via the [Y]/[Z]
keys.
