PRECAUTIONS
R DANGER HIGH RF VOLTAGE! NEVER touch an
antenna or antenna connector while transmitting. This could
cause an electrical shock or burn.
R DANGER! NEVER operate the transceiver near
unshielded electrical blasting caps or in an explosive
atmosphere. This could cause an explosion and death.
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! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels. If
you experience a ringing in your ears, reduce the volume or
discontinue use.
R WARNING! NEVER apply AC power to the [DC13.8V]
socket on the transceiver rear panel. This could cause a fire
or damage the transceiver.
R WARNING! NEVER apply more than 16 V DC to the
[DC13.8V] socket on the transceiver rear panel. This could
cause a fire or damage the transceiver.
R WARNING! NEVER reverse the DC power cable
polarity. This could cause a fire or damage the transceiver.
R WARNING! NEVER remove the fuse holder on the DC
power cable. Excessive current caused by a short could
cause a fire or damage the transceiver.
R WARNING! NEVER let metal, wire or other objects
contact the inside of the transceiver, or make incorrect
contact with connectors on the rear panel. This could cause
an electric shock or damage the transceiver.
R WARNING! NEVER operate or touch the transceiver
with wet hands. This could cause an electric shock or
damage to the transceiver.
R WARNING! NEVER operate the equipment if you notice
an abnormal odor, sound or smoke. Immediately turn OFF
the power and/or remove the DC power cable. Contact your
Icom dealer or distributor for advice.
R WARNING! NEVER put the transceiver on an unstable
place where the transceiver may suddenly move or fall.
This could cause an injury or damage the transceiver.
R WARNING! NEVER operate the transceiver during a
lightning storm. It may result in an electric shock, cause
a fire or damage the transceiver. Always disconnect the
power source and antenna before a storm.
CAUTION: DO NOT expose the transceiver to rain, snow
or any liquids. They could damage the transceiver.
CAUTION: DO NOT change the internal settings of the
transceiver. This could reduce transceiver performance
and/or damage to the transceiver. The transceiver warranty
does not cover any problems caused by unauthorized
internal adjustments.
CAUTION: DO NOT install or place the transceiver in a
place without adequate ventilation, or block any cooling
vents on the top, rear, sides or bottom of the transceiver.
Heat dissipation may be reduced and damage the
transceiver.
CAUTION: NEVER use harsh solvents such as Benzine or
alcohol when cleaning. This could damage the transceiver
surfaces. If the surface becomes dusty or dirty, wipe it clean
with a soft, dry cloth.
CAUTION: NEVER leave the transceiver in areas with
temperatures below –10°C (+14°F) or above +60°C
(+140°F) for mobile operations.
CAUTION: DO NOT place the transceiver in excessively
dusty environments. This could damage the transceiver.
CAUTION: DO NOT place the transceiver against walls
or putting anything on top of the transceiver. This may
overheat the transceiver.
CAUTION: DO NOT set the transceiver's RF output power
to more than a connected linear amplifier's maximum input
level. Otherwise, the linear amplifier will be damaged.
CAUTION: DO NOT use non-Icom microphones. Other
microphones have different pin assignments, and may
damage the transceiver.
BE CAREFUL! The transceiver will become hot when
operating the transceiver continuously for long periods of
time.
NEVER leave the transceiver in an insecure place to avoid
use by unauthorized persons.
Turn OFF the transceiver's power and/or disconnect the DC
power cable when you will not use the transceiver for long
period of time.
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.

To resolve the issue where the Icom IC-9700 is not working on an independent frequency with the green Sub light on and the Dualwatch (DUB) function not functioning on 2 meters:

1. Confirm Dualwatch is Enabled: Hold down the OFF button for 1 second to turn the Dualwatch function ON. This activates independent monitoring of both Main and Sub bands.

2. Select the Proper Band: Touch the grayed frequency readout to select the active band. Ensure the Main and Sub bands are set to different frequencies and not both on 2 meters, as the same frequency cannot be set on both bands.

3. Check Band Settings: Ensure that the Sub band is not set to the same frequency or band as the Main. The IC-9700 supports independent operation on different bands, but not the same frequency on both Main and Sub.

4. Verify TX is on Main Band: Transmission is only possible on the Main band (except in Split Frequency mode), so ensure the Main band is the one you intend to transmit on.

5. Check for Mode Compatibility: Some functions only apply to the selected band and mode. Confirm that the correct mode (FM, SSB, etc.) is selected for the band in use.

Following these steps should allow independent frequency operation with Dualwatch enabled.
