anything less may result in an accident.
RWARNING! NEVER connect the receiver to an AC
outlet. This may pose a fire hazard or result in an electric
shock.
RWARNING! NEVER throw a battery cell into a fire
since as internal battery gas can cause explosion.
RWARNING! NEVER disassemble the battery cell.
If the battery cell’s internal material (electrolyte liquid) gets
into your eyes, wash your eyes with water and obtain treat-
ment from an eye doctor immediately.

FCC INFORMATION
• FOR CLASS B UNINTENTIONAL RADIATORS:
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reason-
able protection against harmful interference in a residential
installation. This equipment generates, uses and can radi-
ate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful inter-
ference to radio communications. However, there is no guar-
antee that interference will not occur in a particular instal-
lation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit differ-
ent from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV techni-
cian for help.
OPERATING THEORY
Electromagnetic radiation, which has frequencies of
20,000 Hz (20 kHz*) and above, is called radio frequency
(RF) energy because, it is useful in radio transmissions. The
IC-R6 receives RF energy from 0.100 MHz* to 1309.995
MHz and converts it into audio frequency (AF) energy which
in turn actuates a loudspeaker to create sound waves.
AF energy is in the range of 20 to 20,000 Hz.
*kHz is an abbreviation of kilohertz or 1000 hertz, MHz is abbrevi-
ation of megahertz or 1,000,000 hertz, where hertz is a unit of fre-
quency.
OPERATING NOTES
The IC-R6 may receive its own oscillated frequency, result-
ing in no reception or only noise reception, on some fre-
quencies.
The IC-R6 may receive interference from extremely strong
signals on different frequencies or when using an external
high-gain antenna.
CAUTION: Changes or modifications to this device, not
expressly approved by Icom Inc., could void your authority
to operate this device under FCC regulations.

batteries become wet, be sure to wipe them dry BEFORE
installing them to the receiver.
• When installing batteries, make sure they are all the same
brand, type and capacity. Also, do not mix new and old bat-
teries together.
• Never use batteries whose insulated covering is damaged.
• Keep battery terminals clean to avoid rust or misscontact.
It’s a good idea to clean battery terminals once a week.
DCaution for the Ni-MH batteries
• CAUTION: Always use the batteries within the speci-
fied temperature range, –5˚C to +60˚C (+23˚F to +140˚F).
Using the batteries out of their specified temperature range
will reduce the battery’s performance and battery life.

• CAUTION: Shorter battery life could occur if the batteries
are left completely discharged, or in an excessive temper-
ature environment (above +55˚C; +131˚F) for an extended
period of time. If the batteries must be left unused for a
long time, they must be detached from the receiver after
charging. Keep them safely in a cool dry place at the fol-
lowing temperature range:
–20˚C to +45˚C (–4˚F to +113˚F) (up to a month)
–20˚C to +35˚C (–4˚F to +95˚F) (up to six months)
–20˚C to +25˚C (–4˚F to +77˚F) (up to a year*)
* We recommend charging the batteries every 6 months.
• If your Ni-MH batteries seem to have no capacity, even
after being charged, completely discharge them by leaving
the power ON overnight. Then, fully charge the batteries
again. If the batteries still do not retain a charge (or only
very little charge), a new batteries must be purchased.
Prior to using the receiver for the first time, the batteries
must be fully charged for optimum life and operation.
• The supplied batteries are rechargeable batteries.
Charge the batteries before first operating the receiver, or
when the batteries become exhausted.
If you want to prolong the battery life, the following points
should be observed:
- Avoid over charging.
- Use the batteries until it becomes almost completely ex-
hausted, under normal conditions.
DCharging caution
• RWARNING! NEVER charge alkaline batteries.
The receiver can charge only the Ni-MH batteries (1.2 V,
1400 mAH typical). Other types of rechargeable battery,
such as Ni-Cd or Li-Ion cannot be charged.
• AVOID over charging— The installed rechargeable batter-
ies can be charged during operation when the AC adapter
or the cigarette lighter cable is connected. To prevent over
charging, the IC-R6 has charging timer that automatically
disconnecting* the charging line electronically after 15 hours
from charging. However, the charging timer will reset and
start charging again when disconnect then reconnecting the
AC adapter or CP-18A/E more than 1 minute interval.
* When the “CHARGE” setting in the Set mode is set to “CHG2 (default),”
the receiver continues to trickle charge after 15 hours have past.
• Recommended temperature range for charging:
between 0°C (+32˚F) and +40°C (+104˚F) by the receiver.
• Use the BC-196SA/SD/BC-153SC AC adapter or CP-18A/
E cigarette liter cable only. NEVER use other manufactur-
ers’ chargers.
• The external DC power supply voltage must be between
12–16 V to charge the batteries and for operation when
using an optional CP-18A/E.
• If the battery icons (“ ” and “ ”) disappear only
1 minute after connecting to the DC power supply, the bat-
teries may have problem. In this case, contact your Icom
dealer/distributor, or purchase new batteries.

• Charging period: Approx. 15 hours*
* Charging pauses when the receiver’s temperature is out of its
specified temperature range (at that time both battery icons
blink), then resumes when it returns to the specified range. In
that case, the charging time will be longer than 15 hours.
• External DC power operation becomes possible when
using an AC adapter or cigarette lighter cable. The installed
Ni-MH batteries can also be charged simultaneously.
• CAUTION: BE SURE to disconnect the CP-18A/E from the
cigarette lighter socket when charging is finished, because,
a slight current still flows in the CP-18A/E and will drain the
vehicle’s battery.
DCharging description
When charging the installed batteries at the first time, or
once the batteries are removed for more than 2 seconds, the
following operations are necessary.
qInstall Ni-MH batteries. (See page 5.)
wPlug the AC adapter into an AC outlet; or the CP-18A/E
into a cigarette lighter socket.
eInsert the adapter plug into [DC4.5V] of the receiver.
• The battery confirmation is displayed.
If the confirmation does not appear, following operation
is necessary.
qDisconnect the adapter plug from [DC4.5V].
wHolding down [FUNC], insert the adapter plug again.
eRelease [FUNC].
NOTE: When no operation is performed for 10 seconds, the
receiver automatically skips these settings, and the receiver
cannot charge the batteries. In that case, remove the bat-
teries for more than 2 seconds and retry these setting from
step q.
