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

i

Your Icom radio generates RF electromagnetic
energy during transmit mode. This radio is de­signed for and classified as “Occupational Use
Only”, meaning it must be used only during the
course of employment by individuals aware of the

hazards, and the ways to minimize such hazards.
This radio is NOT intended for use by the “General Popula­tion” in an uncontrolled environment.

This radio has been tested and complies with the FCC RF expo­sure limits for “Occupational Use Only”. In addition, your Icom radio
complies with the following Standards and Guidelines with regard to
RF energy and electromagnetic energy levels and evaluation of
such levels for exposure to humans:

• FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating
Compliance with FCC Guidelines for Human Exposure to Radio
Frequency Electromagnetic Fields.

• American National Standards Institute (C95.1 – 1992), IEEE Stan­dard for Safety Levels with Respect to Human Exposure to Radio
Frequency Electromagnetic Fields, 3 kHz to 300 GHz.

• American National Standards Institute (C95.3 – 1992), IEEE Rec­ommended Practice for the Measurement of Potentially Hazardous
Electromagnetic Fields – RF and Microwave.

To ensure that your exposure to RF electromag­netic energy is within the FCC allowable limits for
occupational use, always adhere to the following
guidelines:

• DO NOT operate the radio without a proper antenna attached, as

body when transmitting and only use the Icom belt-clips, listed in p. 22,
when attaching the radio to your belt, etc., to ensure FCC RF ex­posure compliance requirements are not exceeded. To provide the
recipients of your transmission the best sound quality, hold the an­tenna at least 5 cm (2 inches) from your mouth, and slightly off to
one side.

The information listed above provides the user with the information
needed to make him or her aware of RF exposure, and what to do to
assure that this radio operates within the FCC RF exposure limits of this
radio.

Electromagnetic Interference/Compatibility

During transmissions, your Icom radio generates RF energy that
can possibly cause interference with other devices or systems. To
avoid such interference, turn off the radio in areas where signs are
posted to do so. DO NOT operate the transmitter in areas that are
sensitive to electromagnetic radiation such as hospitals, aircraft,
and blasting sites.

Battery cautions

• CAUTION! NEVER short the terminals of the battery pack (or
charging terminals of the transceiver). Also, current may flow into
nearby metal objects such as a necklace, so be careful when plac­ing battery packs (or the transceiver) in handbags, etc.

Simply carrying with or placing near metal objects such as a neck­lace, etc. causes shorting. This will damage not only the battery
pack, but also the transceiver.

• NEVER incinerate used battery packs. Internal battery gas may

cause an explosion.

• NEVER immerse the battery pack in water. If the battery pack be-

comes wet, be sure to wipe it dry BEFORE attaching it to the
transceiver.

• Clean the battery terminals to avoid rust or miss contact.

• Keep battery contacts clean. It’s a good idea to clean battery ter-

minals once a week.

If your battery pack seems to have no capacity even after being
charged, completely discharge them, then fully charge the battery
pack again. If the battery pack still does not retain a charge (or only
very little charge), a new battery pack must be purchased.

DD

Charging NOTE

Prior to using the transceiver for the first time, the battery pack must
be fully charged for optimum life and operation.

• Recommended temperature range for charging:
+10°C to +40°C (50°F to 140°F).

• Use the supplied charger or optional charger (BC-119/BC-121/BC­144 for rapid charging, BC-146 for regular charging) only. NEVER
use other manufacturers’ chargers.

The optional BP-209, BP-210 or BP-222 battery packs include
rechargeable Ni-Cd(Ni-MH: BP-210) batteries and can be charged
approx. 300 times. Charge the battery pack before first operating
the transceiver or when the battery pack becomes exhausted.
If you want to charge the battery pack more than 300 times, the fol­lowing points should be observed:

• Avoid overcharging–batteries must be removed from the charger
to stop charging. Batteries should not be charged for more than
15 hours after the LED indicator turns green.

• Use the battery until it becomes almost completely exhausted
under normal conditions.

DD

Battery pack life

When the operating period becomes extremely short even after
charging the battery pack fully, a new battery pack is needed.

NOTE: The charger rapidly charges a battery pack to a speci­fied level, not a completed level, to prevent overcharging. Leave
the battery pack in the charger for a few more hours (up to
15 hours; depending on battery condition) after the LED indica­tor turns green, to charge the battery completely.

‘‘

Battery case (Option)

When using a BP-208 OPTIONAL BATTERY CASE attached to the
transceiver, install 6 AA (R6) size alkaline batteries as illustrated
below.

NOTE: Output power is automatically reduced to 1 W to retain suffi-

cient power in case of an emergency, etc.

DD

CAUTIONS

• Use ALKALINE batteries only.

• Make sure all battery cells are the same brand, type and ca-

pacity.

• Never mix old and new batteries.
Either of the above may cause a fire hazard or damage the
transceiver, if ignored.

• Never incinerate used battery cells since internal battery gas
may cause them to rupture.

• Never expose a detached battery case to water.
If the battery case gets wet, be sure to wipe it dry before using
it.

CTCSS FIND

This transceiver can detect the CTCSS tone frequency in the re­ceived signal. By monitoring a signal that is being transmitted from
the other station, you can determine the tone frequency required to
communicate with them.
This function very useful when you are going to communicate with
unknown CTCSS channel number stations. ‘CTCSS FIND’ scans
all of the CTCSS channels, then stops when a tone frequency is
detected.

q While pushing and holding [MONI], [W/N], turn [OFF/VOL] to

power ON.

w Select the desired CH 1 to CH 15 that you want to assign the

CTCSS tone frequency.

e Push and hold [MONI] until a beep (Pi) is emitted.

• ‘

CTCSS FIND’ start to scan the signal.

r ‘CTCSS FIND’ stops when the tone signal is detected.
t Push [MONI] to determine the tone number.
y Turn the power OFF, and then ON again.

Receiving and transmitting

NOTE: Transmitting without an antenna may damage the trans-

ceiver. See p.4 for antenna attachment.
Turn power ON as described on p. 2.

Program the SIMPLEX/DUPLEX OPERATION and CTCSS
/DTCS tone number (select CH 0 if you will not use the CTCSS
function) before operation.

Receiving:

q Select the desired channel.
w Listen for a transmission and adjust [VOL] to a comfortable lis-

tening level.

• When no transmission is heard, push and hold [MONI] while
adjusting [VOL].

The transceiver is now set to receive desired calls on the selected
channel.

Transmitting:

MONITOR AUDIBLE FUNCTION

The monitor function allows you to open the transceiver’s squelch
manually to check whether a channel is busy or not. The trans­ceiver has 2 conditions for receive standby:

Audible condition:

This condition mutes audio ONLY when
no carrier is present. You can receive (or
monitor) any signals on a channel.

• Push and hold the [MONI], switch to se­lect the audible condition.

Any audio mute functions are cancelled
while pushing the [MONI] switch.

Inaudible condition:

This condition mutes ALL signals except
those directed to you. Therefore you
should check a channel’s condition (busy
or not) with the monitor function before
transmitting.

• Push the [MONI] switch momentarily to

select the inaudible condition.

DD

TIME-OUT TIMER

After continuous transmission for a pre-programmed period, the
time-out timer is activated, causing the transceiver to stop transmit­ting and automatically selects receive.

• The time-out timer function is automatically turned ON when 3
min. has passed.

DD

POWER SAVE FUNCTION

The power save function reduces the current drain to conserve bat­tery power.

• The power save function is automatically turned ON when no
operation is performed or no signal is received for 5 sec.

All signals are
received

Only signals con­taining the proper
tone are received

Setting squelch level

The squelch circuit mutes the received audio signal depending on
the signal strength. Scan proceeds in sequence from lower channel
to higher channel numbers.

q While pushing [PTT] and [W/N], turn the transceiver’s power on

to enter the squelch adjustment mode.

w Push [MONI] to increase the squelch level (tight squelch) or

[W/N] to decrease the squelch level (loose squelch).

• Squelch level will be fixed after 1 sec.

‘‘

Auto scan function

Auto scan function proceeds in sequence from lower channel to
higher channel numbers. Scanning searches for signals automati­cally and makes it easier to locate new stations for contact or lis­tening purpose.

q Turn the CH select knob to CH 16. Scan starts automatically.

• When receiving a signal, scan pauses until a signal disappears.
