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 WARNING! Immediately turn the transceiver

power OFF and remove the power cable if it emits an abnormal odor, sound or smoke. Contact your Icom dealer or distributor for advice.

CAUTION! NEVER put the transceiver in any

unstable place (such as on a slanted surface or vibrated place). This may cause injury and/or damage to the transceiver.

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 prob lems caused by unauthorized internal adjustment.

CAUTION! NEVER apply AC power to the

[DC13.8V] socket on the transceiver rear panel. This could cause a fire or damage the transceiver.

CAUTION! NEVER apply more than 16 V DC,

such as a 24 V battery, to the [DC13.8V] socket on the transceiver rear panel. This could cause a fire or damage the transceiver.

CAUTION!

protrude into the transceiver or into connectors on the rear panel. This may result in an electric shock.

NEVER let metal, wire or other objects

CAUTION! NEVER block any cooling vents on

the top, rear or bottom of the transceiver.

CAUTION! NEVER expose the transceiver to

rain, snow or any liquids.

CAUTION!

place without adequate ventilation. Heat dissipation may be reduced, and the transceiver may be damaged.

NEVER install the transceiver in a

CAUTION! NEVER operate or touch the trans-

ceiver 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-7600, as they can damage the transceiver’s surfaces.

DO NOT push the PTT switch when you don’t actu-

ally desire to transmit.

DO NOT use or place the transceiver in areas with

temperatures below ±0°C (+32°F) or above +50°C (+122°F).

DO NOT place the transceiver in excessively dusty

environments or in direct sunlight.

DO NOT place 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 inadver tent 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.

BE CAREFUL! The rear panel will become hot when operating the transceiver continuously for long periods of time.

Use Icom microphones only (supplied or optional).

Other manufacturers’ microphones have different pin assignments, and connection to the IC-7600 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 trans ceiver and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications.

Turn the transceiver power OFF and/or disconnect the DC power cable when you will not use the trans ceiver 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.

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-7600, see ‘Supplied accessories’ on p. i of this manual.

■ 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 adjustable feet for desktop use. Set the feet to one of two angles depending on your operating preference.

■ Antenna connection

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 ø antenna, and feedline. We recommend 1.5:1 or better of Voltage Standing Wave Ratio (VSWR) on your operating bands. The transmission line should be a coaxial cable. When using a single antenna, use the [ANT1] connector.

CAUTION: Protect your transceiver from light-

ning by using a lightning arrestor.

PL-259 CONNECTOR INSTALLATION EXAMPLE

■ 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 ground 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.

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

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-7600 has an SWR meter to monitor the antenna SWR continuously.

■ Selecting an operating band

The triple band stacking register provides 3 memories for each band key, storing frequency and mode information.

This function is convenient when you operate 3 oper

ating modes on one band. For example, one register is used for a CW frequency, another for a SSB frequency and the other one for a RTTY frequency.

If a band key is pushed once, the frequency and oper

ating mode last used are called up. When the key is pushed again, another stored frequency and operating mode are called up.

See the table below for a list of the bands available and the default settings for each band.

D About 5 MHz band operation (USA version only)

Operation on the 5 MHz band is allowed on 5 discrete frequencies and must adhere to the following:

• USB mode

• Maximum of 50 watts ERP (Effective Radiated Power)

• 2.8 kHz bandwidth

It’s your responsibility to set all controls so that trans mission in this band meets the stringent conditions under which amateur operations may use these frequencies.

NOTE: We recommend that you store these fre- quencies, mode and filter settings into memory channels for easy recall.

* The FCC specifies center frequencies on the

5 MHz band. However, the IC-7600 displays carrier frequency. Therefore, tune the transceiver to

1.5 kHz below the specified FCC channel center frequency.

To assist you in operating the 5 MHz band within the rules specified by the FCC, transmission is illegal on any 5 MHz band frequency other than the ﬁve frequencies indicated in the table above.

✔ About the “P.AMP2”

The “P.AMP 2” is a high gain receive amplifier. When the “P.AMP 2” is used in the presence of strong electromagnetic fields, distortion sometimes results. In such cases, use the transceiver with the “P.AMP 1” or “P.AMP OFF” setting.

The “P.AMP 2” is most effective when:

• Used on bands above 24 MHz and when signals are weak.

• Receive sensitivity is insufficient when using lowgain antennas, or while using a narrow band antenna (such as small loop, a Beverage antenna or a short Yagi antenna).

■ Attenuator

The attenuator prevents a desired signal from distortion when very strong signals are near the desired frequency or when very strong electromagnetic fields, such as from broadcast stations near your location.

➥ Push [ATT] (MF4) several times to set the attenua-

tor 6 dB, 12 dB, 18 dB or attenuator OFF.

➥ Push and hold [ATT] (MF4) for 1 sec. to turn the

<MODE> SSB/CW/RTTY/PSK/AM

PBT (Passband Tuning) electronically narrows the IF passband width by shifting the IF frequency slightly outside of the IF filter passband to reject interference. The IC-7600 uses DSP for the PBT function. Moving both [TWIN-PBT] controls to the same position shifts the IF both above and below the received frequency.

tions, push and hold [PBT-CLR] for 1 sec.

The variable range depends on the passband width and mode. The edge of the variable range is half of the passband width, and PBT is adjustable in 25 (SSB/CW/RTTY/PSK modes) or 100 Hz (AM mode) steps.

• The [TWIN-PBT] controls should normally be set to

VOICE RECORDER FUNCTIONS

■ About digital voice recorder

The IC-7600 has digital voice memories, up to 4 messages for transmit, and up to 20 messages for receive. A maximum message length of 30 sec. can be recorded into receive memory (total message length for all channels of up to 209 sec.) and a total message length of up to 99 sec. can be recorded in transmit memory. The transmit memory is very convenient for repeated CQ and exchange transmissions in contests, as well as when making repeated calls to DX’peditions.
