EXPLICIT DEFINITIONS

WORD DEFINITION

R WARNING!

CAUTION

NOTE

Icom, Icom Inc. and the logo are registered trademarks of Icom Incorporated (Japan) in the United States, the United Kingdom, Germany, France, Spain, Russia and/or other countries.

Personal injury, ﬁre hazard or electric shock may occur.

Equipment damage may occur.

Recommended for optimum use. No risk of personal injury, ﬁre or electric shock.

PRECAUTION

RWARNING RF EXPOSURE! This device emits Radio

Frequency (RF) energy. Extreme caution should be observed when operating this device. If you have any questions regarding RF exposure and safety standards please refer to the Federal Communications Commission Ofﬁce of Engineering and Technology’s report on Evaluating Compliance with FCC Guidelines for Human Radio frequency 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 a

vehicle. Safe driving requires your full attention—anything less may result in an accident.

NEVER connect the transceiver to a power source of more than

16 V DC. This will damage the transceiver.

NEVER connect the transceiver to a power source using reverse

polarity. This will damage the transceiver.

NEVER cut the DC power cable between the DC plug and fuse

holder. If an incorrect connection is made after cutting, the transceiver may be damaged.

NEVER expose the transceiver to rain, snow or any liquids. The

transceiver may be damaged.

NEVER operate or touch the transceiver with wet hands. This may

result 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 the

rear 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 ON and your vehicle’s engine is OFF, the vehicle’s battery will soon become exhausted.

AVOID using or placing the transceiver in direct sunlight or in

areas 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 be damaged.

AVOID the use of chemical agents such as benzine or alcohol

when 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 damage the transceiver if attached.

IMPORTANT!

Detailed installation notes for Icom mobile transceivers to be fitted into vehicles are available. Contact your Icom dealer or distributor.

■ Your ﬁrst contact

Now that you have your IC-2725E installed in your car or shack, you are probably excited to get on the air. We would like to take you through a few basic operation steps to make your ﬁrst “On The Air” an enjoyable experience.

1. Turning ON the transceiver

Before powering up your IC-2725E, you may want to make sure the audio volume and squelch level controls are set in 9–10 o’clock positions.

Although you have purchased a brand new transceiver, some settings may be changed from the factory defaults because of the QC process. Resetting the CPU is necessary to start from factory default.

2. Selecting the main band

The IC-2725E displays 2 frequencies on left and right bands simultaneously. However, transmission, some switches and microphone keys operation are accepted for the main band only.

Quick reference guide

➥ 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-133

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

➥ While pushing both band’s [M/CALL•MW], push [PWR] for

3. Selecting the operating frequency band

The IC-2725E has 2 m and 70 cm bands for each left and right band. The operating band can be exchanged between them, and the same bands, V/V and U/U settings are also possible.

➥ Push the desired band’s (left or right) [MAIN•BAND] for

1 sec. then rotate the appropriate band’s [DIAL].

• Push the [MAIN•BAND] momentarily to return to frequency indication.

4. Tune the frequency

The tuning dial will allow you to dial in the frequency you want to operate. Pages 13 and 14 will instruct you on how to set the tuning speed.

■ Programming memory channels

The IC-2725E has a total of 212 memory channels (including 10 scan edges and 2 call channels) for storing often used operating frequency, repeater settings, etc. Any memory channel can be recalled from either left or right band.

1. Setting a frequency

In VFO mode, set the desired operating frequency with repeater, 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, tuning

step), if desired.

Station B: Tx: 145.350 MHz Rx: 145.950 MHz

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

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

Wide/Narrow setting (Left band only)

Sets both the transmission and reception passband width from wide and narrow. When narrow is set, the transmission deviation and reception passband width become half of the wide setting (approx.). This setting can be set for each memory, call and VFO independently. This item appears when set mode is accessed from left band only.

Operating mode setting

Selects the operating mode for the desired frequency band from FM and AM. This setting can be set for each memory, call and VFO independently.

1st Lo frequency selection

Selects the 1st Lo (Local Oscillator) frequency from normal (n) and reverse (r). By changing local oscillator frequency, the transceiver may reject interference or image frequencies, such as from other stations spurious or the transceiver’s internal oscillator.

This item can also be switched by

pushing

[SET• ] while transmitting (pushing and holding [PTT]) for sub band (nonmain band) setting.

It is helpful in case the transceiver receiving heterodyne spurious emissions, or receiving on an image frequency from own transmitter.

The local oscillator frequency can be switched when selecting a frequency within 2 m band in left band, or 70 cm band in right band only.

A receiver or transceiver is needed to monitor the transmission—compare the received audio output level when receiving a TNC modulated signal with high level voice signals using the microphone. Then adjust the TNC modulated signal to a lower level than the voice modulated signal.

D Adjusting the transmit signal output from

the TNC

When setting data transmission speed to 9600 bps, the data signal coming from the TNC is applied exclusively to the internal limiter circuitry to automatically maintain band width.

NEVER apply data levels from the TNC of over 0.6 V p-p, otherwise the transceiver will not be able to maintain the band width and may possibly interfere with other stations.

1. When using a level meter or synchroscope, adjust the TX audio output level (DATA IN level) from the TNC as follows.

0.4 V p-p (0.2 V rms) : recommended level

0.2 V p-p–0.5 V p-p (0.1–0.25 V rms) : acceptable level

2. When NOT using a measuring device.

q Connect the transceiver to a TNC. w Enter a test mode (“CAL”, etc.) on the TNC, then trans-

mit some test data.

e When the transceiver fails to transmit the test data or

transmits sporadically (TX indicator doesn’t appear or ﬂashes):

- Decrease the TNC output level until the transmit indicator lights continuously.

When transmission is not successful even though the TX indicator lights continuously:

- Increase the TNC output level.
