FOREWORD

We understand that you have a choice of many differ-

ent radios in the market place. We want to take a cou-

ple of moments of your time to thank you for making

the 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

value transceivers in the marketplace) with the new

“PRO.” Focused 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 ama-

teur radio operator!”

IMPORTANT

READ THIS INSTRUCTION MANUAL

CAREFULLY before attempting to operate the

transceiver.

SAVE THIS INSTRUCTION MANUAL. This

manual contains important safety and operating in-

structions for the IC-746PRO.

EXPLICIT DEFINITIONS

PRECAUTIONS

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 Evalu-

ating Compliance with FCC Guidelines for Human Radio

Frequency Electromagnetic Fields (OET Bulletin 65).

R WARNING HIGH VOLTAGE! NEVER attach an

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 +60°C (+140°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 the trans-

ceiver’s 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 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.

WORD DEFINITION

WARNING

Personal injury, ﬁre hazard or electric

shock may occur.

CAUTION Equipment damage may occur.

NOTE

If disregarded, inconvenience only. No

risk or personal injury, fire or electric

shock.
