FOREWORD
Previous view
Thank you for choosing the IC-7850. The IC-7850 has many built-in high technology circuitry and unique functions, such as the Dualwatch on the Main and
Sub bands, a high speed spectrum scope scan, a high-resolution waterfall
screen, and many other outstanding features.
The internal frequency signals in a radio utilizing a PLL are not always sufficiently pure. This results in a considerable number of unwanted spurious
components, called phase noise, in its frequency spectrum. We focused intensively in drastically reducing the phase noise of LO (Local Oscillator) because
the phase noise degrades the interference rejection and noise characteristics
of the receiver. As a result, we succeeded in developing an LO with high purity outputs so that results in an RMDR (Reciprocal Mixing Dynamic Range)
of 101dB with newly developed 1.2kHz Optimum Roofing Filter. Currently no
competitors have been able to achieve this extremely high result performance.
We believe we would not have been able to exceed the standard specifications without our full focus on LO purity.
In addition, Icom that has chosen to base the IC-7850 on an up-conversion,
double super-heterodyne receiver design, which has many advantages over
traditional receiver designs.
We are proud to have developed the IC-7850 for your amateur radio activities,
and hope it brings you years of enjoyable operation.
Please read this instruction manual thoroughly before using the IC-7850.

PRECAUTIONS
Previous viewPrevious view
R DANGER 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. The continuous high volume operation
may cause a ringing in your ears. If you experience
the ringing, reduce the volume level or discontinue
use.
R WARNING! NEVER operate or touch the
transceiver with wet hands. This may result in an electric shock or damage to the transceiver.
R WARNING! NEVER let metal, wire or other ob-
jects protrude into the transceiver or into connectors
on the rear panel. This may result in an electric shock.
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 un-
stable place (such as on a slanted surface or vibrated
place). This may cause injury and/or damage to the
transceiver.
CAUTION: NEVER put the transceiver’s rear
panel side down after lifting up the transceiver by
holding rack mounting handle. This may scratch the
surface of the place or damage the connectors on the
transceiver’s rear panel.
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.
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: The transceiver weighs approximately
23.5 kg (52 lb). Always have two people available to
carry, lift or turn over the transceiver.
CAUTION: The line-voltage receptacle must be
near the transceiver and must be easily accessible.
DO NOT use extension cords.
DO NOT
cohol when cleaning, as they can damage the transceiver’s surfaces.
DO NOT
ally desire to transmit.
use harsh solvents such as benzine or al-
push the PTT switch when you don’t actu-
DO NOT use or store 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 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.
BE CAREFUL!
cover when transmitting continuously for long periods
of time. The top cover may be hot.
Use Icom microphones only (supplied or optional).
Other manufacturers’ microphones have different pin
assignments, and connection to the IC-7850 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.
NEVER touch the transceiver top
CAUTION: NEVER install the transceiver in a
place without adequate ventilation. Heat dissipation
may be reduced, and the transceiver may be damaged.
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 the SSB/CW/RTTY/PSK modes, and 100 Hz steps
for the AM mode.
What is the PBT control?
The PBT function electronically modifies the IF passband
width to reject interference. This transceiver uses the DSP
circuit for the PBT function.
&5 RIT/∂TX CONTROL [RIT/∂TX] (pp. 7-3, 8-5)
Shifts the receive and/or transmit frequency without
changing the transmit and/or receive frequency.
• Rotate the control clockwise to increase the frequency,
or rotate the control counterclockwise to decrease the
frequency. The RIT or ∂TX functions must be ON.
• The shift frequency range is ±9.999 kHz in 1 Hz steps (or
±9.99 kHz in 10 Hz steps).
