iSafety Training InformationYour FRS radio generates RF electromagnetic energy during trans-mit mode. This radio is intended for use by “General Population” inuncontrolled environment.This radio has been tested and complies with the FCC RF expo-sure limits for “General population.” In addition, your Icom radiocomplies with the following Standards and Guidelines with regard toRF energy and electromagnetic energy levels and evaluation ofsuch levels for exposure to humans:• FCC OET Bulletin 65 Edition 01-01 Supplement C, EvaluatingCompliance with FCC Guidelines for Human Exposure to RadioFrequency Electromagnetic Fields.• American National Standards Institute (C95.1-1992), IEEEStandard for Safety Levels with Respect to Human Exposure toRadio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.• American National Standards Institute (C95.3-1992), IEEE Rec-ommended Practice for the Measurement of Potentially Haz-ardous Electromagnetic Fields- RF and Microwave.• The following accessories are authorized for use with this prod-uct. Use of accessories other than those specified may result inRF exposure levels exceeding the FCC requirements for wire-less RF exposure.; Belt Clip, Rechargeable Ni-Cd Battery Pack(BP-202), Speaker microphones (HM-46/HM-75A/HM-131),Earphone microphone (HM-128), Headset (HS-85) andVOX/PTT case (VS-1) + Microphones (HS-94/HS-95/HS-97).IC-4088A_3_Draft.qxd 03.7.16 21:05 Page i (1,1)
iifety Training InformationTo ensure that your expose to RF electromagnetic energy iswithin the FCC allowable limits for general population/uncon-trolled use, always adhere to the following guidelines:•DO NOT transmit for more than 50% of total radio use time(“50% duty cycle”). Transmitting more than 50% of the time cancause FCC RF exposure compliance requirements to be ex-ceeded. The radio is transmitting when the “TX indicator” lightsred. You can cause the radio to transmit by pressing the "PTT"switch.The information listed above provides the user with the informationneeded to make user aware of RF exposure, and what to do to as-sure that this radio operates with the FCC RF exposure limits of thisradio.SUPPLIED ACCESSORY• Belt clip ………………………………… 1Icom, Icom Inc. and the are registered trademarks of Icom Incor-porated (Japan) in the United States, the United Kingdom, Germany,France, Spain, Russia and/or other countries.IC-4088A_3_Draft.qxd 03.7.16 21:05 Page ii (1,1)
iiiIMPORTANTREAD ALL INSTRUCTIONS carefully and completely beforeusing the transceiver.SAVE THIS INSTRUCTION MANUAL— This instruction man-ual contains important operating instructions for the transceiver.PRECAUTIONRDANGER! NEVER operate the transceiver near un-shielded electrical blasting caps or in an explosive atmosphere.RWARNING! NEVER hold the transceiver so that theantenna is very close to, or touching exposed parts of the body,especially the face or eyes, while transmitting. The transceiverwill 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 aheadset or other audio accessories at high volume levels. Hear-ing experts advise against continuous high volume operation. Ifyou experience a ringing in your ears, reduce the volume or dis-continue use.NEVER attempt to charge alkaline cell batteries. Be awarethat external DC power connections will charge batteries insidethe battery case. This will damage not only the battery case butalso the transceiver.DO NOT push the PTT when not actually desiring to trans-mit.IC-4088A_3_Draft.qxd 03.7.16 21:05 Page iii (1,1)
ivPRECAUTION— continuedUSE the optional AC adapter or cigarette lighter cable only forboth operating the transceiver and charging the battery. Othermanufacturer’s AC adapter, cigarette lighter cable or DC powercable 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 inareas 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 stillflows in the radio. Remove the alkaline cells or battery packfrom 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 makeany internal adjustments, changes or modifications by a personwho 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 aqualified technician using the proper test equipment. IC-4088A_3_Draft.qxd 03.7.16 21:05 Page iv (1,1)

53BATTERY CHARGING23■Battery cautionCAUTION NEVER short the terminals. NEVER mix old and new batteries.NEVER incinerate used battery cells. Internal battery gas maycause 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 isconnected. To prevent over charging, the IC-4088A has chargingtimer that automatically disconnecting the charging line electroni-cally after 15 hours from charging. However, the charging timer willreset and start charging again when disconnect then re-connectingthe 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 PACKincludes rechargeable Ni-Cdbatteries and can be charged approx. 300 times. Charge the batterypack before first operating the transceiver or when the battery packbecomes exhausted.If the battery pack seems to have no capacity even after being fullycharged, 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 newbattery pack must be purchased.DDRecycling information (U.S.A. only)The battery (BP-202) that you have purchased isrecyclable. At the end of its life, under variousstate and local laws, it may be illegal to disposeof this battery into the municipal waste stream.Call 1-800-822-8837 for battery recycling optionsin your area or contact your dealer.IC-4088A_3_Draft.qxd 03.7.16 21:05 Page 5 (1,1)

115RECEIVE AND TRANSMIT5✔Talk RangeThe IC-4088A is designed to maximize performance and improvetransmission range in the field. However, the single most impor-tant factor in transmit range (talk power) is the surrounding envi-ronment. These radios are “line of sight” radios and as such,transmission range are influenced by the degree to which youcan “see” the other communicating party. Large concrete struc-tures and heavy foliage or transmission from inside a building orvehicle will reduce the talk power range.•Optimal range: wide, open areas free of obstructions.•Medium range: large buildings or trees blocking your line ofsight.•Minimum range: mountainous areas or areas of heavy foliage.IC-4088A_3_Draft.qxd 03.7.16 21:05 Page 11 (1,1)
126GROUP MODE (CTCSS)■Setting the group codeThe IC-4088A is equipped with 38 group codes. Group mode oper-ation provides communication with silent standby since you will onlyreceive calls from group members using the same group number.First of all, set the same group code number for all group member’stransceivers.To turn ON the group mode op-eration:qPush [MODE] to enter set mode.•“---” (group mode OFF) appearson the display. wPush [Y] or [Z] to select the de-sired code number.ePush [MODE] twice to set thegroup code number and exit setmode.To cancel the group mode oper-ation:qPush [MODE] to enter set mode. •Channel number disappears onthe display. wPush [Y] or [Z] to select “---”(group mode OFF).ePush [MODE] twice to cancelthe group mode and return tooperating condition.NOTE: Only stations with the same group channel number canbe heard during group mode operation, even when the busy in-dicator appears on the display.

Only signalscontaining a specific group code can open the squelch.This conveniently eliminates unwanted audio and is useful ingroup activities or security related activities where unwanted out-put can be a problem. Note that CTCSS group mode is not pri-vate—anyone can receive your calls.The IC-4088A is equipped with 38 tone codes for CTCSS GROUPMODE use. Selecting a code applies it to all 14 operating chan-nels. Each push of [PTT] superimposes your group code over yourtransmit signal; and, only signals containing the same code canopen your squelch. To temporarily hear all signals (including noise)push and hold [MODE]. Do not use CTCSS GROUP MODE if youwant to be able to hear signals on all channels.IC-4088A_3_Draft.qxd 03.7.16 21:05 Page 13 (1,1)
