INSTRUCTION MANUAL  
FRS UHF FM TRANSCEIVER  
i4088A  
This device complies with Part 15 of the FCC rules. Oper-  
ation is subject to the following two conditions: (1) This de-  
vice may not cause harmful interference, and (2) this  
device must accept any interference received, including in-  
terference that may cause undesired operation.  
 
I 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.  
I 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)  
I 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.  
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 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.

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 chargingThe 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.  
D Recycling 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.

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.

RECEIVE AND TRANSMIT  
5
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 sightradios and as such,  
transmission range are influenced by the degree to which you  
can seethe other communicating party. Large concrete struc-  
tures and heavy foliage or transmission from inside a building or  
vehicle will reduce the talk power range.  
5
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.  
 11  
GROUP MODE (CTCSS)  
I Setting the group code  
6
The IC-4088A is equipped with 38 group codes. Group mode oper-  
ation 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 members  
transceivers.  
To turn ON the group mode op-  
eration:

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.
