PRECAUTIONS

R WARNING HIGH RF VOLTAGE! NEVER attach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn.

R WARNING! 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.

R CAUTION! NEVER change the internal settings of the transceiver. This may reduce transceiver performance and/or damage to the transceiver.

In particular, incorrect settings for transmitter circuits, such as output power, idling current, etc., might damage the expensive final devices.

The transceiver warranty does not cover any problems caused by unauthorized internal adjustment.

R CAUTION! NEVER touch the transceiver top cover when transmitting continuously for long periods. The top cover may be hot.

R CAUTION! The transceiver weighs approx. 25 kg (55 lb). Always have two people available to carry, lift or turn over the transceiver.

R CAUTION! The line-voltage receptacle must be near the transceiver and must be easily accessible. Avoid extension cords.

R ACHTUNG! Die Steckdose muß nabe bei diesem Gerät angebracht und zugänglich sein.

R NEVER let metal, wire or other objects protrude into the transceiver or into connectors on the rear panel. This may result in an electric shock.

R NEVER block any cooling vents on the top, rear or bottom of the transceiver.

R NEVER expose the transceiver to rain, snow or any liquids.

R NEVER install the transceiver in a place without adequate ventilation. Heat dissipation may be reduced, and the transceiver may be damaged.

R NEVER operate or touch the transceiver with wet hands. This may result in an electric shock or damage to the transceiver.

DO NOT use chemical agents such as benzine or alcohol when cleaning the IC-7800, as they can damage the transceiver’s surfaces.

DO NOT push the PTT switch when you don’t actually desire to transmit.

AVOID using or storing the transceiver in areas with temperatures below ±0°C (+32°F) or above +50°C (+122°F).

AVOID placing the transceiver in excessively dusty environments or in direct sunlight.

AVOID placing the transceiver against walls or putting anything on top of the transceiver. This may overheat the transceiver.

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

BE CAREFUL! If you use a linear amplifier, set the transceiver’s RF output power to less than the linear amplifier’s maximum input level, otherwise, the linear amplifier will be damaged.

Use Icom microphones only (supplied or optional). Other manufacturers’ microphones have different pin assignments, and connection to the IC-7800 may damage the transceiver or microphone.

The LCD display may have cosmetic imperfections that appear as small dark or light spots. This is not a malfunction or defect, but a normal characteristic of LCD displays.

During maritime mobile operation, keep the transceiver and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications.

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.

For U.S.A. only

CAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations.

@9MULTI-FUNCTION SWITCHES

Push to select the functions indicated in the LCD display to the right of these switches.

•Functions vary depending on the operating condition.

Selects the antenna connector from ANT1, ANT2, ANT3 and ANT4 when pushed. (p. 10-2)

Displays antenna selection memory when pushed for 1 sec.

•When the receive antenna is activated, the antenna which is connected to [ANT4] is used for receive only.

When a transverter is in use, this [ANT] does not function and ‘TRV’ appears.

Selects RF power (Po), SWR, ALC, COMP, VD or ID metering during transmit. (p. 3-10)

Switches the multi-function digital meter ON and OFF when pushed for 1 sec. (p. 3-10)

Selects one of 2 receive RF preamps or bypasses them. (p. 5-9)

•“P. AMP1” activates 10 dB preamp.

•“P. AMP2” activates 16 dB high-gain preamp.

What is the preamp?

The preamp amplifies received signals in the front end circuit to improve S/N ratio and sensitivity. Select “P. AMP1” or “P. AMP2” when receiving weak signals.

Selects 6 dB, 12 dB or 18 dB attenuator when pushed. (p. 5-9)

Selects 3 dB, 6 dB, 9 dB, 12 dB, 18 dB, or 21 dB attenuator when pushed for 1 sec. (p. 5-9)

What is the attenuator?

The attenuator prevents a desired signal from distorting when very strong signals are near the desired frequency, or when very strong electric fields, such as from a broadcasting station, are near your location.

Turns the speech compressor ON and OFF in SSB mode. (p. 6-5)

Switches the narrow, middle or wide compression when pushed for 1 sec.

What is the speech compressor?

The speech compressor compresses the transmitter audio input to increase the average audio output level, to increase talk power. This function is effective for long-distance communication or when propagation conditions are poor.

■ 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 preference.

■ 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.

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 connec- tion could cause an explosion or electric shock.

■ Antenna connection

PL-259 CONNECTOR INSTALLATION EXAMPLE

Coupling ring				10 mm (soft solder)
w				10 mm			Soft
							solder
					1–2 mm
e					solder solder

r

Slide the coupling ring down. Strip the cable jacket and soft solder.

Strip the cable as shown at left. Soft solder the center conductor.

Slide the connector body on and solder it.

Screw the coupling ring onto the connector body.

30 mm ≈ 9⁄8 in 10 mm ≈ 3⁄8 in 1–2 mm ≈ 1⁄16 in

For radio communications, the antenna is of critical importance, along with output power and receiver sensitivity. Select antenna(s), such as a well-matched 50 Ω antenna, and feedline. We recommend 1.5:1 or better of Voltage Standing Wave Ratio (VSWR) for your desired band. Of course, the transmission line should be a coaxial cable.

When using 1 antenna, use the [ANT1] connector.

CAUTION: Protect your transceiver from lightning by using a lightning arrestor.

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 transistors. In this case, an antenna tuner is useful to match the transceiver and antenna. Low SWR allows full power for transmitting. The IC-7800 has an SWR meter to monitor the antenna SWR continuously.

■ CF (Compact Flash) memory card

Read/write indicator	Insert the supplied CF (Compact Flash) memory
	card into the CF memory card slot.
	• To remove the CF memory card, push-in the button, lo-
	cated at left hand side of the slot.

Make sure to install the memory card correctly. NEVER insert or remove the CF memory card when the read/write indicator lights or blinks.
