PRECAUTIONS
RDANGER HIGH RF VOLTAGE! NEVER
attach an antenna or internal antenna connector
during transmission. This may result in an electrical
shock or burn.
RWARNING! NEVER operate the transceiver
with a headset or other audio accessories at high
volume levels. Hearing experts advise against continu-
ous high volume operation. If you experience a ringing
in your ears, reduce the volume or discontinue use.
RWARNING! NEVER operate or touch the
transceiver with wet hands. This may result in an
electric shock or damage to the transceiver.
RWARNING! NEVER apply AC power to the
[DC13.8V] socket on the transceiver rear panel. This
could cause a fire or damage the transceiver.
RWARNING! NEVER cut the DC power cable
between the DC plug and fuse holder. If an incorrect
connection is made after cutting, the transceiver may
be damaged.
RWARNING! NEVER apply more than 16 V
DC to the [DC13.8V] socket on the transceiver rear
panel, or use reverse polarity. This could cause a fire
or damage the transceiver.
RWARNING! 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.
RWARNING! Immediately turn OFF the trans-
ceiver power and remove the power cable if it emits
an abnormal odor, sound or smoke. Contact your
Icom dealer or distributor for advice.
RWARNING! 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.
#!54)/. NEVER change the internal settings of
the transceiver. This may reduce transceiver perfor-
mance 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.
#!54)/. NEVER block any cooling vents on
the top, rear, sides or bottom of the transceiver.
#!54)/. NEVER expose the transceiver to
rain, snow or any liquids.
#!54)/. NEVER install the transceiver in a
place without adequate ventilation. Heat dissipation
may be reduced, and the transceiver may be damaged.
DO NOT use harsh solvents such as benzine or
alcohol when cleaning, as they will damage the trans-
ceiver 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.
"% #!2%&5, 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.
"% #!2%&5, The rear panel will become hot
when operating the transceiver continuously for long
periods of time.
USE only the specified microphone. Other manufac-
turers’ microphones have different pin assignments,
and connection to the IC-7410 may damage the
transceiver or microphone.
During maritime mobile operation, keep the trans-
ceiver and microphone as far away as possible from
the magnetic navigation compass to prevent errone-
ous indications.
Turn OFF the transceiver’s power and/or disconnect
the DC power cable when you will not use the trans-
ceiver for long period of time.

* When the SEND terminal controls an inductive load (such as a relay), a counter-electromotive force can cause
the transceiver’s malfunction or damage. To prevent this, we recommend adding a switching diode, such as an
“1SS133,” on the load side of the circuit to the counter-electromotive force absorption.
When the diode is added, a switching delay of the relay may occur. Be sure to check its switching action before
operation.
