Safety Training Information
Your FRS radio generates RF electromagnetic energy during trans-
mit mode. This radio is intended for use by “General Population” in
uncontrolled environment.
This radio has been tested and complies with the FCC RF expo-
sure limits for “General population.” 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 01-01 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 Rec-
ommended Practice for the Measurement of Potentially Haz-
ardous Electromagnetic Fields- RF and Microwave.
• The following accessories are authorized for use with this prod-
uct. Use of accessories other than those specified may result in
RF exposure levels exceeding the FCC requirements for wire-
less RF exposure.; Belt Clip, Rechargeable Ni-Cd Battery Pack
(BP-202), Speaker microphones (HM-46/HM-75A/HM-131),
Earphone microphone (HM-128), Headset (HS-85) and
VOX/PTT case (VS-1) + Microphones (HS-94/HS-95/HS-97).

fety Training Information
To ensure that your expose to RF electromagnetic energy is
within the FCC allowable limits for general population/uncon-
trolled use, always adhere to the following guidelines:
DO NOT transmit for more than 50% of total radio use time
(“50% duty cycle”). Transmitting more than 50% of the time can
cause FCC RF exposure compliance requirements to be ex-
ceeded. The radio is transmitting when the “TX indicator” lights
red. You can cause the radio to transmit by pressing the "PTT"
switch.
The information listed above provides the user with the information
needed to make user aware of RF exposure, and what to do to as-
sure that this radio operates with the FCC RF exposure limits of this
radio.

IMPORTANT
READ ALL INSTRUCTIONS carefully and completely before
using the transceiver.
SAVE THIS INSTRUCTION MANUAL— This instruction man-
ual contains important operating instructions for the transceiver.
PRECAUTION
RDANGER! NEVER operate the transceiver near un-
shielded electrical blasting caps or in an explosive atmosphere.
RWARNING! NEVER hold the transceiver so that the
antenna is very close to, or touching exposed parts of the body,
especially the face or eyes, while transmitting. The transceiver
will perform best if the microphone is 2 to 4 in. (5 to 10 cm)
away and the transceiver is vertical.
RWARNING! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels. Hear-
ing experts advise against continuous high volume operation. If
you experience a ringing in your ears, reduce the volume or dis-
continue use.
NEVER attempt to charge alkaline cell batteries. Be aware
that external DC power connections will charge batteries inside
the battery case. This will damage not only the battery case but
also the transceiver.
DO NOT push the PTT when not actually desiring to trans-
mit.
IC-4088A_3_Draft.qxd 03.7.16 21:05 Page iii (1,1)
iv
PRECAUTION— continued
USE the optional AC adapter or cigarette lighter cable only for
both operating the transceiver and charging the battery. Other
manufacturer’s AC adapter, cigarette lighter cable or DC power
cable with external power supply may damage the transceiver.
Place the unit in a secure place to avoid inadvertent use by chil-
dren.
AVOID using or placing the transceiver in direct sunlight or in
areas with temperatures below –4˚F (–20°C) or above +122˚F
(+50°C).
The use of non-Icom battery packs/chargers may impair trans-
ceiver performance and invalidate the warranty.
Even when the transceiver power is OFF, a slight current still
flows in the radio. Remove the alkaline cells or battery pack
from the transceiver when not using it for a long time. Other-
wise, the installed batteries will become exhausted.
FCC WARNING: NEVER open the transceiver’s case to make
any internal adjustments, changes or modifications by a person
who not expressly approved by Icom Inc., could void your au-
thority to operate this transceiver under FCC regulations.
Any transceiver’s adjustments, replacement must be made by a
qualified technician using the proper test equipment.

Battery caution
CAUTION NEVER short the terminals.
NEVER mix old and new batteries.
NEVER incinerate used battery cells. Internal battery gas may
cause explosion.
Make sure all battery cells are the same brand, type and capacity.
AVOID over charging The BP-202 can be charged during oper-
ation when the AC adapter or the optional cigarette lighter cable is
connected. To prevent over charging, the IC-4088A has charging
timer that automatically disconnecting the charging line electroni-
cally after 15 hours from charging. However, the charging timer will
reset and start charging again when disconnect then re-connecting
the AC adapter or CP-18A more than 1 min. interval.
Recommended temperature range for charging:
+50˚F to +104˚F (+10˚C to +40˚C)
The optional BP-202
BATTERY PACK
includes rechargeable Ni-Cd
batteries and can be charged approx. 300 times. Charge the battery
pack before rst operating the transceiver or when the battery pack
becomes exhausted.
If the battery pack seems to have no capacity even after being fully
charged, completely discharge it by leaving the power ON all day.
Then, fully charge the battery pack again.
If the battery pack still does not retain a charge (or very little), a new
battery pack must be purchased.
DDRecycling information (U.S.A. only)
The battery (BP-202) that you have purchased is
recyclable. At the end of its life, under various
state and local laws, it may be illegal to dispose
of this battery into the municipal waste stream.
Call 1-800-822-8837 for battery recycling options
in your area or contact your dealer.

Talk Range
The IC-4088A is designed to maximize performance and improve
transmission range in the eld. However, the single most impor-
tant factor in transmit range (talk power) is the surrounding envi-
ronment. These radios are line of sight radios and as such,
transmission range are influenced by the degree to which you
can see the other communicating party. Large concrete struc-
tures and heavy foliage or transmission from inside a building or
vehicle will reduce the talk power range.
Optimal range: wide, open areas free of obstructions.
Medium range: large buildings or trees blocking your line of
sight.
Minimum range: mountainous areas or areas of heavy foliage.

What is CTCSS (Continuous Tone Coded Squelch System)
GROUP MODE ?
CTCSS (Continuous Tone Coded Squelch System) GROUP
MODE allows communication with silent stand by. Only signals
containing a specic group code can open the squelch.
This conveniently eliminates unwanted audio and is useful in
group activities or security related activities where unwanted out-
put can be a problem. Note that CTCSS group mode is not pri-
vateanyone can receive your calls.
The IC-4088A is equipped with 38 tone codes for CTCSS GROUP
MODE use. Selecting a code applies it to all 14 operating chan-
nels. Each push of [PTT] superimposes your group code over your
transmit signal; and, only signals containing the same code can
open your squelch. To temporarily hear all signals (including noise)
push and hold [MODE]. Do not use CTCSS GROUP MODE if you
want to be able to hear signals on all channels.

DESKTOP CHARGER
+ AD-105
DESKTOP CHARGER ADAPTER
Rapidly charges battery pack in 1 to 1.5 hrs. An AC adapter is packed with
the BC-119N. The AD-105 must be used with the BC-119N for charging the
battery pack. The CP-17L or OPC-515L can be used instead of the supplied
AC adapter. (p. 7)
