■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 Com-
munications Commission Office 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 fire 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—any-
thing 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 fire 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 bat-
tery 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 per-
formance 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 equip-
ment 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/OFFD
➥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/MHz] to select the VFO mode.
•Push [M/CALL] one or more times to select the memory,
Call or marine channel* mode.
DSetting a frequency
qIf necessary, push [V/MHz] to select the VFO mode.
wRotate [DIAL] to set the frequency.
•
The frequency changes according to the selected tuning step.
• Push [V/MHz] one or more times, to toggle the frequency
step between 1 MHz and 10 MHz, if desired.
DTuning step selection
The tuning step is the smallest selectable frequency incre-
ment you can use to set the operating frequency. The follow-
ing 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/MHz] to select the VFO mode.
wPush [SET] to enter the Set mode.
e
Push [SET] or [MONI] one or more times, until “TS” appears.
rRotate [DIAL] to select the desired tuning step.
tPush any key, other than [SET] or [MONI], to save the
entry and exit the Set mode.
DCall 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.
DLock 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.
DMonitor function
This function is used to listen to weak signals without dis-
turbing 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.
DSquelch 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:
qPush [ ] to turn OFF the power.
wWhile holding down [LOCK] (SET), hold down []for
1 second to turn ON the power and enter the Initial Set
mode.
ePush [SET] or [MONI] one or more times, to select the "SQL"
item.
rRotate [DIAL] to select "AT" (Attenuator).
tPush []to save and exit the Initial Set mode.
yRotate [SQL] clockwise past the 12 o’clock position, to
activate the squelch attenuator.
• The attenuation level can be adjusted up to approximate-
ly 20 dB, between the 12 o’clock and fully clockwise posi-
tions.
• When setting the squelch from the microphone, a level
greater than ‘17’ activates the attenuator.
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] be-
tween 10 and 12 o’clock (7 to 17 level when it is set using
the HM-133V).
DS-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:
qPush [ ] to turn OFF the power.
wWhile holding down [LOCK] (SET), hold down []for 1 sec-
ond to turn ON the power and enter the Initial Set mode.
ePush [SET] or [MONI] one or more times, to select the
"SQL" item.
rRotate [DIAL] to select "SS" (S-meter squelch).
tPush []to exit the Initial Set mode.
yRotate [SQL] clockwise past the 12 o’clock position, to
activate the S-meter squelch.
DSelecting output power
Set the output power level to suit your operating require-
ments. Lower output power during short-distance commu-
nications 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.

D Priority watch, Dualwatch/Tri-watch
• Priority watch
A priority watch
sequentially
searches through
all TAG channels,
while also moni-
toring the Priority
channel. When a
signal is detect-
ed on the Prior-
ity channel, the
watch pauses until the signal disappears; when a signal is
detected on a channel other than the Priority channel, the
Priority watch switches to Dualwatch, until the signal disap-
pears.
• Dualwatch
Dualwatch monitors the Pri-
ority channel while receiving
on a TAG channel. The watch
pauses when a signal is received on the Priority channel.
• Tri-watch*
Tri-watch monitors the
Priority channel and
the Call channel while
receiving on a TAG
channel.
Tri-watch switches to
Dualwatch, when receiving a signal on the Call channel.
*One or more TAG channels other than the Call and Priority chan-
nels must be programmed, to start the Tri-watch.
