FOREWORD
READ ALL INSTRUCTIONS carefully and completely
before using the transceiver.
SAVE 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.
CAUTIONS
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—any-
thing 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 trans-
ceiver.
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 se-
rial 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 transceiver power
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).
AVOID the use of chemical agents such as benzine or alco-
hol when cleaning, as they can damage the transceiver’s sur-
faces.
Place unit in a secure place to avoid inadvertent use by chil-
dren.
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 active. This
is normal and does not indicate LCD malfunction.
Uneven areas may be displayed depending on display con-
tents in some cases.
After displaying the same screen continuously for long peri-
ods, image ‘burn-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 impor-
tance, along with output power and sensitivity. The trans-
ceiver accepts a 50 Ωantenna and less than 1.5 : 1 of
Voltage Standing Wave Ratio (VSWR). High SWR values
not only may damage the transceiver but also lead to TVI or
BCI problems.

8SCRATCH PAD MEMORY
■
What is a scratch pad memory?
During VFO operation, the transceiver automatically memo-
rizes operating frequency information, separate from regular
memory channels, when transmitting on a new frequency.
There are 2 types of scratch pad memories, those for simplex
operation, L1–L5, and those for duplex (repeater) operation,
R1–R5. These memories can be conveniently recalled.
When memory mode is selected, the frequency is not pro-
grammed into a scratch pad.
■Calling up a scratch pad
memory
qPush [M/C] to select the call channel.
•Push [CHG/L] if [M/C] is not displayed.
•“C” appears when the call channel is selected.
wRotate the desired band’s tuning dial to select a scratch
pad memory.
•Previously transmitted frequency and one of “L1–L5” appears for
simplex memories (rotate tuning dial left); one of “R1–R5” ap-
pears for duplex memories (rotate tuning dial right).
•When first applying power or after CPU resetting, scratch pad
memories contain no data and therefore cannot be selected.
ePush [V/M
H
] or [M/C] to exit the scratch pad memory.
•The 5th scratch pad memory (L5 or R5) will be cleared
when transmitting on a new frequency. If the transmit fre-
quency is already stored in a scratch pad memory, the
scratch pad memory is not cleared but the order is
changed.
•When transmitting on a scratch pad memory, that memory
becomes the 1st scratch pad memory (L1 or R1) and the
order is changed.

■EX-1759 installation
The EX-1759
INFRARED RECEIVER
can be installed for 2 differ-
ent purposes depending on the HM-90 charger. This is be-
cause the EX-1759 has both an infrared receiver and a
microphone connector which contains microphone charging
capabilities.
When using the IC-2800H main unit
Attach the EX-1759 to a suitable location for receiving infrared
signals, e.g. sun visor, etc.
When using the connector for a microphone charger
Attach the EX-1759 to a suitable location for receiving infrared
signals and where it can be connected to cable, e.g. the con-
sole, etc.
DO NOT attach the EX-1759 where it will be subject to di-
rect sunlight as it cannot detect infrared signals under such
conditions.
Optional infrared sub receiver
An optional EX-1513
INFRARED SUB RECEIVER
is available to
increase the remote control reliability and extend the control-
lable area. Connect the EX-1513 to the inside connector of
the EX-1759.
The HM-98 can be connected and used with the EX-1759,
however, the optional wireless microphone cannot be used
in such a case.
(When using the
main unit for mic
charging)

■Squelch delay
During operation, received signal strength often fluctuates.
This can result in annoying repeated opening and closing of
the squelch during reception of the same signal. The trans-
ceiver has a built-in squelch delay function which helps pre-
vent this. When both stations are operating from a fixed
location e.g. during packet operation, this function should be
set to “short.”

OTHER FUNCTIONS
DAdjusting the transmit signal output from
the TNC
When setting data transmission speed to 9600 bps, the data
signal coming from the TNC is applied exclusively to the in-
ternal limiter circuitry to automatically maintain band width.
NEVER apply data levels from the TNC of over 0.6 Vp-p, oth-
erwise the transceiver will not be able to maintain the band
width and may possibly interfere with other stations.
1.When using a level meter or synchroscope, adjust the
TX audio output level (DATA IN level) from the TNC as
follows.
0.4 Vp-p (0.2 Vrms) : recommended level
0.2 Vp-p–0.5 Vp-p (0.1 Vrms–0.25 Vrms) : acceptable level
2.When NOT using a measuring device.
qConnect the transceiver to a TNC.
wEnter a test mode (“CAL”, etc.) on the TNC, then transmit
some test data.
e
When the transceiver fails to transmit the test data or trans-
mits sporadically (TX indicator doesn’t appear or flashes):
- Decrease the TNC output level until the transmit indicator
lights continuously.
When transmission is not successful even though the TX
indicator lights continuously:
- Increase the TNC output level.
