INSTRUCTION MANUAL

VHF/HF ALL MODE TRANSCEIVER

i746

This device complies with Part 15 of the FCC rules. Operation is sub-

ject to the following two conditions: (1) This device may not cause

harmful interference, and (2) this device must accept any interference

received, including interference that may cause undesired operation.

The IC-746’s which display the “CE” symbol, comply

with the essential requirements of the 89/336/EEC di-

rective for Electromagnetic Compatibility. This compli-

ance is based on conformity with the ETSI speciﬁcation

prETS300 684 (EMC product standard for Commer-

cially Available Amateur Radio Equipment).

IMPORTANT

WORD DEFINITION

RWARNING Personal injury, fire hazard or electric

shock may occur.

CAUTION Equipment damage may occur.

NOTE If disregarded, inconvenience only. No risk

of personal injury, ﬁre or electric shock.

READ THIS INSTRUCTION MANUAL CAREFULLY

before attempting to operate the transceiver.

SAVE THIS INSTRUCTION MANUAL—This manual

contains important safety and operating instructions for

the IC-746.

PRECAUTIONS

RWARNING! HIGH VOLTAGE! NEVER attach an

antenna or internal antenna connector during trans-

mission. This may result in an electric shock or burn.

RNEVER apply AC to the [DC13.8V] socket on the

transceiver rear panel. This could cause a ﬁre or ruin

the transceiver.

RNEVER apply more than 16 V DC, such as a 24 V

battery, to the [DC13.8V] socket on the transceiver rear

panel. This could cause a ﬁre or ruin the transceiver.

RNEVER 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 allow children to play with equipment contain-

ing a radio transmitter.

NEVER expose the transceiver to rain, snow or any liq-

uids.

AVOID using or placing the transceiver in areas with

temperatures 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 per-

manent damage to the transceiver if left there for ex-

tended periods.

AVOID placing the transceiver in excessively dusty en-

vironments or in direct sunlight.

AVOID placing the transceiver against walls or putting

anything on top of the transceiver. This will obstruct

heat dissipation.

During mobile operation, DO NOT operate the trans-

ceiver without running the vehicle’s engine. When

transceiver 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 start-

ing the vehicle. This will avoid possible damage to the

transceiver by ignition voltage spikes.

During maritime mobile operation, keep the transceiver

and microphone as far away as possible from the mag-

netic navigation compass to prevent erroneous indica-

tions.

BE CAREFUL! The heatsink will become hot when op-

erating 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 lin-

ear ampliﬁer’s maximum input level, otherwise, the lin-

ear ampliﬁer will be damaged.

Use Icom microphones only (supplied or optional).

Other manufacturer’s microphones have different pin

assignments and connection to the IC-746 may dam-

age the transceiver.

EXPLICIT DEFINITIONS

The explicit deﬁnitions described below apply to this in-

struction manual.

BUILT-IN DSP

The IC-746’s DSP digitally transposes receive audio

components in all modes of operation to produce de-

sired AF frequency characteristics at the IF stage of

the transceiver. DSP provides the following functions:

➩Noise reduction—reduces various types of noise

and enhances receive signal components only.

➩

Automatic notch filter—automatically reduces single

beat interference and protects the receive voice signals.

➩Selectable APF—a total of 3 passband widths are

selectable (80/160/320 Hz), for super-narrow filter

APF functions in CW mode. The APF center fre-

quency is adjustable.
