R WARNING RF EXPOSURE! This device emits

Radio Frequency (RF) energy. Extreme caution should be
observed when operating this device. If you have any
questions regarding RF exposure and safety standards
please refer to the Federal Communications Commission
Office of Engineering and Technology’s report on Evalu­ating Compliance with FCC Guidelines for Human Radio
Frequency Electromagnetic Fields (OET Bulletin 65).

R WARNING HIGH VOLTAGE! NEVER attach an

antenna or internal antenna connector during transmis­sion. This may result in an electrical shock or burn.

R NEVER apply AC to the [DC13.8V] socket on the

transceiver rear panel. This could cause a fire or damage
the transceiver.

R NEVER apply more than 16 V DC, such as a 24 V

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

R NEVER let metal, wire or other objects touch any in-

ternal part or connectors on the rear panel of the trans­ceiver. This may result in an electric shock.

R NEVER connect or use the HM-151 (microphone)

with other transceiver. This could cause damage to the
transceiver. The HM-151 is designed for use with the IC­7000 ONLY

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

AVOID using or placing the transceiver in areas with tem­peratures below –10°C (+14°F) or above +60°C (+140°F).
Be aware that temperatures on a vehicle’s dashboard can
exceed +80°C (+176°F), resulting in permanent damage
to the transceiver if left there for extended periods.

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 will obstruct heat
dissipation.

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

During mobile operation, NEVER place the transceiver
where air bag deployment may be obstructed.

During mobile operation, DO NOT place the transceiver
where hot or cold air blows directly onto it.

During mobile operation, DO NOT operate the transceiver
without running the vehicle’s engine. When the trans­ceiver’s power is ON and your vehicle’s engine is OFF,
the vehicle’s battery will soon become exhausted.

Make sure the transceiver power is OFF before starting
the vehicle. This will avoid possible damage to the trans­ceiver by ignition voltage spikes.

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

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

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.

Use Icom microphones only (supplied or optional). Other
manufacturer’s microphones have different pin assign­ments, and connection to the IC-7000 may damage the
transceiver.

Beat signals may be heard on some frequencies.
These will occur as a result of circuit construction.

For U.S.A. only

Caution: Changes or modifications to this transceiver,
not expressly approved by Icom Inc., could void your
authority to operate this transceiver 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-7000, see ‘Supplied acces­sories’ on p. i-1 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 an adjustable stand
for desktop use. Set the stand to one of two angles de­pending on your operating conditions. (see description
on right hand page)

■ 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, buried copper rod. Make the distance be­tween the [GND] terminal and ground as short as pos­sible.

R WARNING: NEVER connect the [GND] ter-

minal to a gas pipe or electric conduit, since the
connection could cause an explosion or electric
shock.

■ Antenna connection

For radio communications the antenna is of critical im­portance for output power and sensitivity. Use well­matched 50-ohm antennas and coaxial feedline. An
SWR (standing wave radio) of 1.5:1 or lower is recom­mended when transmitting.

CAUTION: Protect your transceiver from lightning

by using a lightning arrestor.

ANTENNA SWR

Each antenna is tuned for a specified frequency
range and SWR increases outside that 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 used to match the
transceiver and antenna. Low SWR allows full power
for transmitting even when using the antenna tuner.
The IC-7000 has an SWR meter to monitor the an­tenna SWR continuously.

D Differences between VFO and memory mode

VFO MODE

Each VFO shows a frequency and operating mode. If
the frequency or operating mode is changed, the VFO
automatically memorizes the new frequency or oper­ating mode.

When VFO settings are changed with frequency and
mode from another VFO or memory mode, the last­used frequency and operating mode for that VFO ap­pear.

[EXAMPLE]

MEMORYMODE(pgs. 102–110)

Each memory channel shows a frequency and oper­ating mode like a VFO. Even if the frequency or mode

is changed, the memory channel does not memorize
the new frequency or operating mode.

When a memory channel is changed with frquency
and mode from another memory channel or VFO
mode, the memorized frequency and operating mode
appear.

[EXAMPLE]

BASIC OPERATION

VFO is an abbreviation of Variable Frequency Oscilla­tor, and traditionally refers to an oscillator.

The IC-7000 VFO is somewhat different. The VFO dis­play of the IC-7000 acts like a computer’s window and
can show one frequency and one operating mode.

You can call up a desired frequency to the VFO with

the memo pad-read key (p. 112) or the memory trans­fer function (p. 109). You can also change the fre­quency with [DIAL] and select an operating mode with
[MODE] key or call up previously accessed frequency
and modes with the band stacking register (p. 28).

The IC-7000 has two VFOs, specially suited for split

frequency operation. The VFOs are called VFO A and
VFO B. You can use the desired VFO to call up a fre­quency and operating mode for operation.

BASIC OPERATION

The triple band stacking register provides 3 memories
in one band. 3 sets of frequency and operating mode
on each band are automatically stored when used.

If a band key (on the HM-151) is pushed once, the last
used frequency and operating mode 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 bands available
and the default settings for each band.

BASIC OPERATION

■ Squelch and receive (RF) sensitivity

Adjusts the RF gain and squelch threshold level. The
squelch removes noise output from the speaker
(closed position) when no signal is received.

• The squelch is particularly effective for FM. It is also avail­able for other modes.

•The 12 to 1 o’clock position is recommended for any set­ting of the [RF/SQL] control.

•The control can be set as ‘Auto’ (RF gain control in SSB,
CW and RTTY; squelch control in AM, FM and WFM (RF
gain is fixed at maximum) in the miscellaneous (others)
set mode as follows (p. 131).

Adjusting RF gain (Receive sensitivity)

Normally, [RF/SQL] is set to the 11 o’clock position.
Rotate [RF/SQL] to the 11 o’clock position for maxi­mum sensitivity.

• Rotating counterclockwise from the maximum position re­duces sensitivity.

• The S-meter indicates receive sensitivity.

Adjusting squelch (Removing non-signal noise)

Rotate [RF/SQL] clockwise when receiving no signal,
until the noise just disappears.

• [RX] indicator light goes out.

• Rotating [RF/SQL] past the threshold point invokes the S-
meter squelch—this allows you to set a minimum signal
level needed to open the squelch.

• When setting as RF gain/squelch control

•When functioning as RF gain control

(Squelch is fixed open; SSB, CW, RTTY only)

•When functioning as squelch control (RF gain is

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 is the operator’s responsibility to set all controls so
that the transmission in this band meets the stringent
conditions under which we may use these frequencies.

NOTE: We recommend that you store these fre­quencies, mode and filter settings into the memory
channel for easy recall.

*The channel center frequencies that are specified

by the FCC, show the center frequency of their
passband. However, the IC-7000 displays carrier
point frequency, so set 1.5 kHz below from FCC
channel center frequency.

RECEIVE AND TRANSMIT

■ Repeater operation

A repeater amplifies received signals and retransmits
them at a different frequency. When using a repeater,
the transmit frequency is shifted from the receive fre­quency by an offset frequency. A repeater can be ac­cessed using split frequency operation with the shift
frequency set to the repeater’s offset frequency.

For accessing a repeater which requires a repeater
tone, set the repeater tone frequency in the FM tone
set mode as described on the next page.
