transmit.
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.
AVOID placing the transceiver in excessively dusty environments or in direct sunlight.
DO NOT push the PTT when not actually desiring to
AVOID using or placing the transceiver in areas with
temperatures below ±0°C (+32°F) or above +50°C
(+122°F).
AVOID placing the transceiver against walls or putting
anything on top of the transceiver. This will obstruct
heat dissipation.
R CAUTION! NEVER change the internal settings of the transceiver. This result in reduced transceiver performance and/or damage to the transceiver.
Place unit in a secure place to avoid inadvertent use
by children.
R CAUTION! NEVER touch the transceiver top
cover when transmitting continuously for long periods.
It will become hot.
BE CAREFUL! The top panel will become hot when
operating the transceiver continuously for long periods.
In particular, incorrect settings for transmitter circuits,
such as output power, idling current, etc., might damage the expensive final devices.
BE CAREFUL! If a linear amplifier is connected, set
the transceiver’s RF output power to less than the linear amplifier’s maximum input level, otherwise, the linear amplifier will be damaged.
The transceiver warranty does not cover any problems
caused by unauthorized internal adjustment.
Use Icom microphones only (supplied or optional).
Other manufacturer’s microphones have different pin
assignments, and connection to the IC-7800 may damage the transceiver.
R CAUTION! The transceiver weighs approx. 25 kg
(55 lb). 2 peoples should be present to carry, lift up or
turn over the transceiver, etc.
The LCD display may have cosmetic imperfections that
appear as small or dark spots. This is not a malfunction
or defect, but a normal characteristic of LCD displays.
R CAUTION! The socket-outlet must be near the
transceiver and must be easily accessible.
R ACHTUNG! Die Steckdose muß nabe bei
diesem Gerät angebracht und zugänglich sein.
During maritime mobile operation, keep the transceiver
and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications.
R NEVER let metal, wire or other objects touch any
internal part or connectors on the rear panel of the
transceiver. This may result in an electric shock.
Turn [I/O] switch (on the rear panel) OFF and/or disconnect the AC power cable from the AC outlet when
you will not use the transceiver for long period of time.
R NEVER let objects impede the operation of the
cooling fan on the rear panel.
R NEVER expose the transceiver to rain, snow or

INSTALLATION AND CONNECTIONS
■ Unpacking
After unpacking, immediately report any damage to the
delivering carrier or dealer. Keep the shipping cartons.
For a description and a diagram of accessory equipment included with the IC-7800, see ‘Supplied accessories’ on p. iii of this manual.
■ Antenna jumper cable connection
Connect the supplied coaxial cable (terminated with
BNC connectors) between [RX ANT A— IN] and [RX
ANT A— OUT], and, [RX ANT B— IN] and [RX ANT
B— OUT], respectively.
When connecting an external filter unit, pre-amplifier,
etc., connect the unit between [RX ANT A/B— IN] and
[RX ANT A/B— OUT] connectors.
■ Selecting a location
Select a location for the transceiver that allows adequate air circulation, free from extreme heat, cold, or
vibrations, and away from TV sets, TV antenna elements, radios and other electromagnetic sources.
The base of the transceiver has an adjustable stand
for desktop use. Set the stand to one of two angles depending on your operating conditions.
■ Rack mounting handle attachment
Remove the four screws from both sides of the front
panel and the two screws from both sides of the side
panel, then attach the rack mounting handles to the
sides of the transceiver using the supplied screws.
2-2
INSTALLATION AND CONNECTIONS
■ Grounding
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other problems, ground the transceiver through the GROUND
terminal on the rear panel.
For best results, connect a heavy gauge wire or strap
to a long earth-sunk copper rod. Make the distance between the [GND] terminal and ground as short as possible.
R WARNING: NEVER connect the [GND]
terminal to a gas or electric pipe, since the connection could cause an explosion or electric shock.
■ Antenna connection
For radio communications, the antenna is of critical importance, along with output power and sensitivity. Select antenna(s), such as a well-matched 50 Ω antenna,
and feedline. 1.5:1 or better of Voltage Standing Wave
Ratio (VSWR) is recommended for your desired band.
Of course, the transmission line should be a coaxial
cable.

Strip the cable as
shown at left. Soft solder the center conductor.
When using 1 antenna, use the [ANT1] connector.
CAUTION: Protect your transceiver from lightning
by using a lightning arrestor.
solder solder
Slide the connector
body on and solder it.
Antenna SWR
Each antenna is tuned for a specified frequency
range and SWR may be increased out-of-range.
When the SWR is higher than approx. 2.0:1, the
transceiver’s power drops to protect the final transistor. In this case, an antenna tuner is useful to match
the transceiver and antenna. Low SWR allows full
power for transmitting even when using the antenna
tuner. The IC-7800 has an SWR meter to monitor the
antenna SWR continuously.
Screw the coupling
ring
onto
the
connector body.
30 mm ≈ 9⁄8 in 10 mm ≈ 3⁄8 in 1–2 mm ≈ 1⁄16 in
■ CF (Compact Flash) memory card
Insert the supplied CF (Compact Flash) memory
card into the CF memory card slot.
Accessing indicator
• To remove the CF memory card, push-in the button, located at left hand side of the slot.

■ When first applying power (CPU resetting)
Before first applying power, make sure all connections
required for your system are complete by referring to
Section 2. Then, reset the transceiver using the following procedure.
Resetting CLEARS all programmed contents in
memory channels and returns programmed values
in set mode to default values.
q Turn the main power ON with [I/O] on the rear

BASIC OPERATIONS
■ Selecting an operating band
The triple band stacking register provides 3 memories
in one band. 3 sets of a frequency and operating mode
on each band are automatically stored when used.
Band keys
If a band key is pushed once, the frequency and operating mode last used are called up. When the key is
pushed again, another stored frequency and operating
mode are called up.
This function is convenient when you operate 3 operating modes on one band. For example, one register
is used for a CW frequency, another for an SSB frequency and the other one for an RTTY frequency.
See the table below for a list of the band available and
the default settings for each band.

BASIC OPERATIONS
■ Basic transmit operation
Before transmitting, monitor your selected operating frequency to make sure transmitting won’t
cause interference to other stations on the same
frequency. It’s good Amateur practice to listen
first, and then, even if nothing is heard, ask “is
the frequency in use” once or twice, before you
being operating on that frequency.
