FOREWORD

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

This FRS (Family Radio Service) FM transceiver meets the FCC

regulation (FCC Part 95). This transceiver is designed for those

who require top-grade quality, performance and outstanding re-

liability under the most demanding conditions.

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)

IC-4088A_2.qxd 03.6.23 11:58 Page i (1,1)

■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.

IC-4088A_2.qxd 03.6.23 11:58 Page iii (1,1)

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.
