RWARNING RF EXPOSURE! This device emits RadioFrequency (RF) energy. Extreme caution should be observed whenoperating this device. If you have any questions regarding RF expo-sure and safety standards please refer to the Federal Communica-tions Commission Office of Engineering and Technology’s report onEvaluating Compliance with FCC Guidelines for Human Radio fre-quency Electromagnetic Fields (OET Bulletin 65).

RWARNING! NEVER connect the transceiver to an AC out-let. This may pose a fire hazard or result in an electric shock.

RWARNING! NEVER operate the transceiver while driving avehicle. Safe driving requires your full attention—anything less mayresult in an accident.

NEVER connect the transceiver to a power source of more than16 V DC. This will damage the transceiver.

NEVER connect the transceiver to a power source using reversepolarity. This will damage the transceiver.

NEVER cut the DC power cable between the DC plug and fuseholder. If an incorrect connection is made after cutting, the transceivermay be damaged.

NEVER expose the transceiver to rain, snow or any liquids. Thetransceiver may be damaged.

NEVER operate or touch the transceiver with wet hands. This mayresult in an electric shock or damage the transceiver.

NEVER place the transceiver where normal operation of the vehi-cle may be hindered or where it could cause bodily injury.

NEVER let objects impede the operation of the cooling fan on therear panel.

DO NOT push the PTT when not actually desiring to transmit.DO NOT allow children to play with any radio equipment contain-ing a transmitter.

During mobile operation, DO NOT operate the transceiver with-out running the vehicle’s engine. When the transceiver’s power is ONand your vehicle’s engine is OFF, the vehicle’s battery will soon be-come exhausted.

AVOID using or placing the transceiver in direct sunlight or inareas with temperatures below –10°C or above +60°C.

BE CAREFUL! The transceiver will become hot when operat-ing it continuously for long periods.

AVOID setting the transceiver in a place without adequate venti-lation. Heat dissipation may be affected, and the transceiver may bedamaged.

AVOID the use of chemical agents such as benzine or alcoholwhen cleaning, as they can damage the transceiver’s surfaces.

USE Icom microphones only (supplied or optional). Other manu-facturer’s microphones have different pin assignments and may dam-age the transceiver if attached.

IMPORTANT!Detailed installation notes for Icom mobile transceivers tobe fitted into vehicles are available. Contact your Icomdealer or distributor.

� Your first contactNow that you have your IC-2725E installed in your car orshack, you are probably excited to get on the air. We wouldlike to take you through a few basic operation steps to makeyour first “On The Air” an enjoyable experience.

1. Turning ON the transceiverBefore powering up your IC-2725E, you may want to makesure the audio volume and squelch level controls are set in9–10 o’clock positions.

Although you have purchased a brand new transceiver, somesettings may be changed from the factory defaults becauseof the QC process. Resetting the CPU is necessary to startfrom factory default.

➥ While pushing both band’s [M/CALL•MW], push [PWR] for1 sec. to reset the CPU.

2. Selecting the main bandThe IC-2725E displays 2 frequencies on left and right bandssimultaneously. However, transmission, some switches andmicrophone keys operation are accepted for the main bandonly.

➥ Push the desired band’s (left or right) [MAIN•BAND] to se-lect the main band.• “Q” appears for the main band.

Using the HM-133You can select the main band from the HM-133.

3. Selecting the operating frequency bandThe IC-2725E has 2 m and 70 cm bands for each left andright band. The operating band can be exchanged betweenthem, and the same bands, V/V and U/U settings are alsopossible.

➥ Push the desired band’s (left or right) [MAIN•BAND] for1 sec. then rotate the appropriate band’s [DIAL].• Push the [MAIN•BAND] momentarily to return to frequency indi-

cation.

4. Tune the frequencyThe tuning dial will allow you to dial in the frequency you wantto operate. Pages 13 and 14 will instruct you on how to setthe tuning speed.

Using the HM-133You can directly enter the frequency with the HM-133 keypadfor the main band.

2. Repeater tone Push [TONE•DTMF] several times until “T” appears, if the re-peater requires a subaudible tone to be accessed.

Using the HM-133Plus or minus duplex selection and the repeater tone settingcan be made easily via HM-133.Push [DUP– 7(TONE)] for minus duplex; [DUP+ 8(TSQLS)]for plus duplex selection, push [FUNC] then [DUP– 7(TONE)]to turn the repeater tone ON.

� Programming memory channelsThe IC-2725E has a total of 212 memory channels (including10 scan edges and 2 call channels) for storing often used op-erating frequency, repeater settings, etc. Any memory channel can be recalled from either left or rightband.

1. Setting a frequencyIn VFO mode, set the desired operating frequency with re-peater, tone and tuning steps, etc. ➥ Push the desired band’s [V/MHz•SCAN] to select VFO.➥ Rotate the same band’s [DIAL] to set the desired frequency.

• Set other data, such as repeater tone, duplex information, tuningstep), if desired.

2. Selecting a memory channel Push the same band’s [M/CALL•MW] for 1 sec., then rotatethe [DIAL] to select the desired memory channel.• “!” indicator and memory channel number blink.

3. Writing a memory channelPush and hold the [M/CALL•MW] for 1 sec. to program.• 3 beeps sound• Return to VFO mode automatically after the program.• Memory channel number automatically increases when continuing

to push the [M/CALL•MW] after programming.

ANTENNA INFORMATIONFor radio communications, the antenna is of critical impor-tance, to maximize your output power and receiver sensi-tivity. The transceiver accepts a 50 Ω antenna and lessthan 1:1.5 of Voltage Standing Wave Ratio (VSWR). HighSWR values not only may damage the transceiver but alsolead to TVI or BCI problems.

� Squelch attenuatorThe transceiver has an RF attenuator related to the squelchlevel setting. Approx. 10 dB attenuation is obtained at maxi-mum setting. The squelch attenuator allows you to set a minimum signallevel needed to open the squelch. The attenuator function canbe deactivated in initial set mode.

➥ Rotate [SQL] clockwise past the 12 o’clock position to ac-tivate the squelch attenuator.• Attenuation level can be adjusted up to 10 dB (approx.) between

12 o’clock and fully clockwise position.• When setting the squelch from the microphone, a level greater

than ‘19’ activates the squelch attenuator.

NOTE: The squelch attenuator functions even when themonitor function is in use. Thus set the [SQL] control within10 to 12 o’clock position is recommended when using themonitor function.

� General

Repeaters allow you to extend the operational range of yourradio because a repeater has much higher output power thanthe typical transceiver.

Normally, a repeater has indipendent frequencies for each re-ceiver and transmitter.A subaudible tone may also be required to access a repeater

Reference amateur radio hand books and local ham maga-zines for details of local repeaters such as repeater input/out-put frequencies and locations.

• Repeater operation flow chart

• Repeater settings can be stored into a memory channel.

Setp 3:Set the duplex (shifting) direction (– duplex or +duplex).- Set the offset frequency (shifting value), if required.

Setp 4:Set the subaudible tone (repeater tone) encoder function ON.- Set the subaudible tone frequency, if required.

Setp 1:Set the desired band to operate the repeater.

Setp 2:Set the desired receive frequency (repeater output frequency).

Repeater example;Receives the 145.950 MHz signal and the detected audio signals are transmitted on 145.30 MHz simulta-neously.
