■ Precautions

RWARNING RF EXPOSURE! This device emits Ra-

dio 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 Ofﬁ ce of Engineering and Technology’s report on Evaluating Compliance with FCC Guidelines for Human Radio frequency Electromagnetic Fields (OET Bulletin 65).

RWARNING! NEVER connect the transceiver to an AC

outlet. This may pose a ﬁ re hazard or result in an electric shock.

RWARNING! NEVER cut the DC power cable be-

tween the DC plug and fuse holder. If an incorrect connection is made after cutting, the transceiver may be damaged.

RWARNING! NEVER operate the transceiver while

driving a vehicle. Safe driving requires your full attention—anything less may result in an accident.

RWARNING! NEVER connect the transceiver to a

power source of more than 16 V DC or use reverse polarity. This could cause a ﬁ re or damage the transceiver.

RWARNING! NEVER operate or touch the transceiver

with wet hands. This may result in an electric shock or damage the transceiver.

RWARNING! NEVER place the transceiver where

normal operation of the vehicle may be hindered or where it could cause bodily injury.

RWARNING! NEVER let metal, wire or other objects

touch any internal part of the transceiver. This may result in an electric shock.

CAUTION: NEVER expose the transceiver to rain, snow

or any liquids. The transceiver may be damaged.

DO NOT push the PTT when not actually intending to transmit. KEEP the transceiver out of the reach of children.

During mobile operation,

DO NOT operate the transceiver

without running the vehicle’s engine. When the transceiver’s power is ON and your vehicle’s engine is OFF, the vehicle’s battery will soon become exhausted.

BE CAREFUL! The transceiver will become hot when op-

erating it continuously for long periods of time.

DO NOT set the transceiver in a place without adequate ven-

tilation. Heat dissipation may be affected, and the transceiver may be damaged.

DO NOT use or place the transceiver in direct sunlight or in areas

with temperatures below –10°C (+14˚F) or above +60°C (+140˚F).

DO NOT use harsh solvents such as benzine or alcohol

when cleaning, as they will damage the transceiver’s surfaces.

USE only Icom microphones (supplied or optional). Other

manufacturer’s microphones have different pin assignments and may damage the transceiver if attached.

Approved Icom optional equipment is designed for optimal performance when used with an Icom transceiver. Icom is not responsible for the destruction or damage to an Icom transceiver in the event the Icom transceiver is used with equipment that is not manufactured or approved by Icom.

This instruction sheet describes only basic operations. For more detailed instructions, go to our web site (URL: http://www.icom. co.jp/world/index.html) to view or download the full IC-2300H instruction manual. In the instruction manual, some options or some functions may not be available for this version. Please ask your dealer for details.

Turning power ON/OFF D

➥ Hold down [ ] for 1 second to turn the power ON or OFF.

D VFO mode selection

The IC-2300H has two basic operating modes; the VFO mode and the memory mode. ➥ Push [V/MH z] to select the VFO mode.

•Push [M/CALL] one or more times to select the memory,

Call or marine channel* mode.

D Setting a frequency

q If necessary, push [V/MH z] to select the VFO mode. w Rotate [DIAL] to set the frequency.

•

The frequency changes according to the selected tuning step.

• Push [V/MH z] one or more times, to toggle the frequency step between 1 MHz and 10 MHz, if desired.

D Tuning step selection

The tuning step is the smallest selectable frequency increment you can use to set the operating frequency. The following tuning steps are selectable.

• 5 kHz • 6.25 kHz • 10 kHz • 12.5 kHz • 15 kHz

• 20 kHz • 25 kHz • 30 kHz • 50 kHz

NOTE: For convenience, select the tuning step that match-

es the frequency intervals of the repeaters in your area.

q If necessary, push [V/MH z] to select the VFO mode. w Push [SET] to enter the Set mode. e

Push [SET] or [MONI] one or more times, until “TS” appears.

r Rotate [DIAL] to select the desired tuning step. t Push any key, other than [SET] or [MONI], to save the

entry and exit the Set mode.

D Call channel selection

➥

Push [M/CALL] one or more times to select the Call channel.

• “C” appears instead of a memory channel number.

• Push [M/CALL] to select the marine channel* mode, push again to return to the memory mode, or push [V/MHz] to select the VFO mode.

D Lock function

Use the Lock function to prevent accidental channel changes and unnecessary function access. ➥ Hold down [LOCK] (SET) for 1 second to turn the Lock

function ON or OFF.

• [PTT], [MONI], [VOL] and [SQL] can be used, even while the Frequency Lock function is ON.

D Monitor function

This function is used to listen to weak signals without disturbing the squelch setting, or to open the squelch manually, even when the tone squelch is in use. ➥ Push [MONI] to open the squelch.

• The “BUSY” icon blinks.

• Push [MONI] again to cancel the function.

D Squelch attenuator

The transceiver has an RF attenuator related to the squelch level setting. Approximately 20 dB of attenuation is obtained at the maximum setting.

Turn ON the Squelch Attenuator function:

q Push [ ] to turn OFF the power. w While holding down [LOCK] (SET), hold down [

] for 1 second to turn ON the power and enter the Initial Set mode.

e Push [SET] or [MONI] one or more times, to select the "SQL"

item.

r Rotate [DIAL] to select "AT" (Attenuator). t Push [

] to save and exit the Initial Set mode.

y Rotate [SQL] clockwise past the 12 o’clock position, to

activate the squelch attenuator.

• The attenuation level can be adjusted up to approximately 20 dB, between the 12 o’clock and fully clockwise positions.

NOTE: When using with the Monitor function. The squelch attenuator functions even when the Monitor

function is in use. It is recommended to set [SQL] between 10 and 12 o’clock.

D S-meter squelch

The transceiver has an S-meter squelch. The S-meter squelch allows you to set minimum signal level needed to open the squelch.

Turn ON the S-meter squelch function:

q Push [ ] to turn OFF the power. w While holding down [LOCK] (SET), hold down [

] for 1 sec-

ond to turn ON the power and enter the Initial Set mode.

e Push [SET] or [MONI] one or more times, to select the

"SQL" item.

r Rotate [DIAL] to select "SS" (S-meter squelch). t Push [

] to exit the Initial Set mode.

y Rotate [SQL] clockwise past the 12 o’clock position, to

activate the S-meter squelch.

D Selecting output power

Set the output power level to suit your operating requirements. Lower output power during short-distance communications may reduce the possibility of interference to other stations and will reduce current consumption. ➥ Push [LOW] one or more times to select the output pow-

er.

• The power level can be changed even while transmitting.

*: Transmission is inhibited in the marine channel mode.

Basic operation ■

q PTT SWITCH

Hold down to transmit; release to receive.

w UP/DOWN KEYS [UP] or [DN]

➥ Push either key to change the operating frequency,
