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

❍

■ ATS (Automatic Transponder System)

This convenient function automatically checks station availability
within the operating range, and alerts you via function display in­dication. (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:

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)

IMPORTANT

READ ALL INSTRUCTIONS carefully and completely before
using the transceiver.

SAVE THIS INSTRUCTION MANUAL— This instruction man­ual 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. Hear­ing experts advise against continuous high volume operation. If
you experience a ringing in your ears, reduce the volume or dis­continue 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.

iii

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 chil­dren.

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 trans­ceiver 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. Other­wise, 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 au­thority 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 electroni­cally 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
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 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.

✔ What is squelch?

A squelch circuit allows muting of undesired noise while receiving
no signal and emit audio while receiving signals.
This provides quiet standby. The [MODE] key changes the
squelch setting. This is useful to listen to weak signals that do
not open the squelch.

number appears on the display.

• While pushing and holding [Y] or
[Z] keys, the displayed channel
changes continuously until chan­nel number “1” appears.

To keep the automatic selection,
release the [Y] or [Z] keys then
push and hold them again.

• When displayed channel stops at channel number “1,” a beep is
emitted.

IMPORTANT:

To maximize the readability of the transmitted signal, pause a
few sec. after pushing [PTT], hold the transceiver 4 to 6 in. (10 to
15 cm) from your mouth and speak at a normal voice level.

NOTE:

The transceiver has an auto power save function to conserve
the battery power. The power save function activates automati­cally when no signal is received for 5 sec.

RECEIVE AND TRANSMIT

✔ Talk Range

The IC-4088A is designed to maximize performance and improve
transmission range in the field. However, the single most impor-
tant factor in transmit range (talk power) is the surrounding envi­ronment. 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 struc­tures 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.

■ Setting the group code

The IC-4088A is equipped with 38 group codes. Group mode oper­ation provides communication with silent standby since you will only
receive calls from group members using the same group number.

First of all, set the same group code number for all group member’s
transceivers.

To turn ON the group mode op­eration:

Push [MODE] to enter set mode.

✔ 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 specific group code can open the squelch.
This conveniently eliminates unwanted audio and is useful in
group activities or security related activities where unwanted out­put can be a problem. Note that CTCSS group mode is not pri­vate—anyone can receive your calls.

6

6

The IC-4088A is equipped with 38 tone codes for CTCSS GROUP
MODE use. Selecting a code applies it to all 14 operating chan­nels. 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.
