This instruction
manual contains important safety and operating
instructions for the IC-706MKIIG.
RWWAARRNNIINNGG HHIIGGHH VVOOLLTTAAGG!! NNVVRR
attach an antenna or internal antenna connector dur-
ing transmission. This may result in an electrical shock
or burn.
RNNVVRRapply AC to the [DC13.8V] socket on the
transceiver rear panel. This could cause a fire or ruin
the transceiver.
RNNVVRRapply 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 ruin the transceiv-
er.
RNNVVRRlet metal, wire or other objects touch any
internal part or connectors on the rear panel of the
transceiver. This will cause electric shock.
RNNVVRRexpose the transceiver to rain, snow or
any liquids.
NNVVRR allow children to play with the transceiver.
AAVVOOIIDD 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, resulting in permanent
damage to the transceiver’s front panel if left there for
extended periods.
AAVVOOIIDD placing the transceiver in excessively dusty
environments or in direct sunlight.
AAVVOOIIDD placing the transceiver against walls or putting
anything on top of the transceiver. This will obstruct
heat dissipation.
During mobile operation, DDOO NNOOTToperate the trans-
ceiver 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.
Make sure the transceiver power is OFF before start-
ing the vehicle. This will avoid possible damage to the
transceiver by ignition voltage spikes.
During maritime mobile operation, keep the transceiv-
er and microphone as far away as possible from the
magnetic navigation compass to prevent erroneous
indications.
BB CCAARRFFUULL!!
The heatsink will become hot when
operating the transceiver continuously for long peri-
ods.
BB CCAARRFFUULL!!If a linear amplifier is connected, set
the transceiver’s RF output power to less than the lin-
ear amplifier’s maximum input level, otherwise, the lin-
ear amplifier will be damaged.
Use Icom microphones only (supplied or optional).
Other manufacturer’s microphones have different pin
assignments and connection to the IC-706MKIIG 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
CCaauuttiioonn::Changes or modifications to this transceiver, not
expressly approved by Icom Inc., could void your authority
to operate this transceiver under FCC regulations.

After unpacking, immediately report any damage to
the delivering carrier or dealer. Keep the shipping car-

■GGrroouunnddiinngg
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other prob-
lems, 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 GROUND terminal and ground as short
as possible.
■AAnntteennnnaa
Select antenna(s), such as a well-matched 50 Ω
antenna, and feedline. The transmission line should
be a coaxial cable. 1.5 : 1 or better of Voltage
Standing Wave Ratio (VSWR) is recommended for
your required band. Of course, the transmission line
should be a coaxial cable.

AANNTTNNNNAA SSWWRR
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 transis-
tors. In this case, an optional 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-706MKIIG has an SWR
meter to monitor the antenna SWR continuously.

FREQUENCY SETTING
■VVFFOO ddeessccrriippttiioonn
VFO is an abbreviation of Variable Frequency
Oscillator, and traditionally refers to an oscillator. The
IC-706MKIIG’s VFO can store a frequency and an
operating mode.
You can call up a desired frequency to a VFO with the
memo pad-read switch (p. 42) or with the memory
transfer switch (p. 42). You can also change the fre-
quency with the main dial and select an operating
mode with the [MODE] switch or call up previously
accessed frequency and modes with the band stack-
ing register (p. 19).
The IC-706MKIIG 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.
