i4088S

FOREWORD

Thank you for purchasing the IC-4088S
Service) FM transceiver. This C.R.S. FM transceiver is designed for
those who require top quality, performance and outstanding relia­bility under the most demanding conditions.

UHF C.R.S. (Citizen Radio

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

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 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.

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 operate the transceiver near unshielded electrical blast-

ing caps or in an explosive atmosphere.

DO NOT push the PTT when not actually desiring to transmit.

i

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 0°C or above +55°C.

The use of non-Icom battery packs 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.

DO NOT modify the transceiver for any reason.

KEEP the transceiver from the heavy rain, and NEVER immerse

it in the water. The transceiver construction is

weather resis-

tant, (meets JIS grade 4) not waterproof.

When the low battery indicator blinks, the performance of the trans­ceiver cannot be guaranteed.

DO NOT transmit for more than 3 sec., when operating with the

group mode and/or call ring function. Transmission in a form other
than speech is limited, and should be of a duration of less than 3
sec. as a compliance to ACA requirements in Australia.

This device complies with Standard Australia
Specification No. AS/NZS4365-1996.

■ 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 when the AC

adapter or the DC power cable with a DC power supply is con­nected. To prevent over charging, the IC-4088S 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 DC power cable more than 1 min. interval.

Recommended temperature range for charging: +10˚C to +40˚C

NEVER connect an AC adapter or DC power cable with an external
DC power supply that outputs lower than 5.7 V DC and more than

6.3 V DC voltage when charging the installed BP-202.

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.

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 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-4088S 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.

While receiving While transmitting

A repeater amplifies received signals and re-transmits them on a
different channel, allowing you to communicate over greater dis­tances with improved reliability. When using a repeater, the transmit
channel is shifted from the receive channel by 30 channels. Please
ask you dealer regarding repeater availability in your local area.

✔ 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.

8

8

The IC-4088S is equipped with 38 tone codes for CTCSS GROUP
MODE use. Selecting a code applies it to all 40 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.
