FOREWORD
Thank you for purchasing the IC-4088A FRS FM transceiver.

FEATURES
❍
Free of user-license and applications
❍
Voice scrambler function for communication
privacy
❍
External DC-IN jack for both operation and
battery charging
(Optional BC-149A or CP-18A is required)
❍
All 14 FRS channels are available
❍
Powerful 500 mW (ERP) high output power
❍
38 convenient group channels
■ATS (Automatic Transponder System)
This convenient function automatically checks station availability
within the operating range, and alerts you via function display in-
dication. (p. 20)
In addition, a manual transponder is also available for “GROUP
MODE” operation to check availability of stations in a specified
group within the operating range. In this case, the transceiver
alerts you via beeps. (p. 12)

■WATER-RESISTANT* CONSTRUCTION
Water-resistant* construction is employed, and this unit can be
used in a wide range of applications.
*Meets JIS water-protection specification grade 4.
■GROUP MODE (BUILT-IN CTCSS: Continuous Tone
Coded Squelch System)
CTCSS encoder/decoder are standard, providing quiet stand-by.
Audio (voice) signals are output only when a signal with matched
CTCSS tone signal is received. This is very helpful for group
communications. In addition, 38 different CTCSS frequencies
are available. (p. 12)
■2 types of “Ring” function
The “Smart-Ring” function and the “Call-Ring” function are avail-
able for smart and simple station calls providing a telephone-
style ring when called. 10 different ringing tones are available.

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.

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.
