Explicit Definitions; Precautions - Icom IC-746PRO Instruction Manual

FOREWORD
We understand making you have a choice of many dif-
ferent radios in the market place.I want to take a cou-
ple of moments of your time to thank you for making
your IC-746PRO your radio of choice, and hope you
agree with Icom's philosophy of "technology first".Many
hours of research and development went into the de-
sign of your IC-746PRO.
Rather than completely redesigning all areas to create
a new radio, the engineering team at Icom decided to
follow in the footsteps of the IC-746 (one of the best
values in the marketplace) with the new "PRO". Fo-
cused on real world improvements compiled over the
last few years from letters, phone calls, E-Mails and
newsgroup postings the engineering team at Icom is
proud to say "many of these changes were compiled
from a list of suggestions from you, the amateur radio
operator!"

PRECAUTIONS

R WARNING RF EXPOSURE!
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 Evalu-
ating Compliance with FCC Guidelines for Human Radio
frequency Electromagnetic Fields (OET Bulletin 65).
R WARNING HIGH VOLTAGE! NEVER
antenna or internal antenna connector during transmis-
sion. This may result in an electrical shock or burn.
R NEVER
apply AC to the [DC13.8V] jack on the trans-
ceiver rear panel. This could cause a fire or ruin the trans-
ceiver.
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 ruin the transceiver.
R NEVER
let metal, wire or other objects touch any in-
ternal part or connectors on the rear panel of the trans-
ceiver. This may result in an electric shock.
NEVER expose the transceiver to rain, snow or any liquids.
AVOID using or placing the transceiver in areas with tem-
peratures below –10°C (+14°F) or above +50°C (+122°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 envi-
ronments 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, DO NOT operate the transceiver
without running the vehicle's engine. When transceiver
power is ON and your vehicle's engine is OFF, the vehi-
cle's battery will soon become exhausted.
Make sure the transceiver power is OFF before starting
the vehicle. This will avoid possible damage to the trans-
ceiver 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 heatsink will become hot when oper-
ating 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 am-
plifier's maximum input level, otherwise, the linear ampli-
fier will be damaged.
Use Icom microphones only (supplied or optional). Other
manufacturer's microphones have different pin assign-
ments, and connection to the IC-746PRO may damage
the transceiver.
