RWARNING! NEVER connect the receiver via the

OPC-254L to an AC outlet. This may pose a ﬁre hazard or re-

sult in an electric shock.

RWARNING! NEVER operate the receiver while dri-

ving a vehicle. Safe driving requires your full attention— any-

thing less may result in an accident.

NEVER connect the receiver to a power source of more

than 14 V DC. This will damage the receiver.

NEVER connect the receiver to a power source using re-

verse polarity. This will damage the receiver.

NEVER cut the DC power cable between the DC plug and

fuse holder. If an incorrect connection is made after cutting,

the receiver may be damaged.

DO NOT leave the main unit powered ON and connected

to a vehicle’s electrical system. The main unit draws approx.

550 mA. This will eventually drain the vehicle’s battery.

NEVER expose the receiver to rain, snow or any liquids.

The receiver may be damaged.

NEVER operate or touch the receiver with wet hands. This

may result in an electric shock or damage the receiver.

NEVER place the receiver where normal operation of the

vehicle may be hindered or where it could cause bodily injury.

NEVER let objects impede the operation of the cooling fan

on the rear panel.

AVOID using or placing the receiver in direct sunlight or in

areas with temperatures below –10°C (+14°F) or above

+60°C (+140°F).

BE CAREFUL! The receiver will become hot when op-

erating it continuously for long periods.

AVOID setting the receiver in a place without adequate

ventilation. Heat dissipation may be affected, and the receiver

may be damaged.

AVOID the use of chemical agents such as benzine or al-

cohol when cleaning, as they can damage the receiver’s sur-

faces.

For U.S.A. only

CAUTION: Changes or modiﬁcations to this device, not ex-

pressly approved by Icom Inc., could void your authority to

operate this device under FCC regulations.

■ Receive mode selection

Receive modes are determined by the physical properties of

the radio signals. The receiver has 6 receive modes: USB

LSB, CW, AM, WFM and FM modes. The mode selection is

stored independently in each memory channel.

Additionally, IC-R2500 has a DV or P25 mode when the op-

tional UT-118 or UT-122 units are installed, respectively. In

DV or P25 mode, the right band can select AM, FM and WFM

mode only.

Typically, AM mode is used for the AM broadcast stations

(0.495–1.620 MHz), air band (118–135.995 MHz), and short-

wave broadcasts. WFM is used for FM broadcast stations

(76–107.9 MHz). WFM mode can be selected on 1300 MHz

band or below.

BASIC OPERATION

Duplex communication uses two different frequencies for

transmitting and receiving. Generally, duplex is used in com-

munication through a repeater, some utility communications,

etc.

During duplex operation, the transmit station frequency is

shifted from the receive station frequency by the offset fre-

quency. Repeater information (offset frequency and shift di-

rection) can be programmed into memory channels. (p. 24)

BASIC OPERATION

■ Single band operation

Single band/Dualwatch operation

Dualwatch operation monitors two frequencies simultane-

ously. The IC-R2500 has two independent receiver circuits:

left band, and right band

(available frequencies, operating mode

and functions are different depending on bands).

Single band operation is useful when only one frequency is

being watched. The right band can be inhibited.

from two different antennas, ANT1 and ANT2, and automati-

cally selects the strongest signal. This feature is useful when

you are listening in a moving vehicle or the transmitting sta-

tion itself is moving. Diversity receiving is available from 50

MHz to 1300 MHz on FM, P25 and DV modes only.

qTurn the sub band OFF to select single band operation as

described at left.

How does the Reverse action work?

When the reverse action is selected for either the tone

squelch, “tSqL-r,” or DTCS squelch, “dtCS-r,” and a signal

with the matched tone (or DTCS) is received, the squelch

closes, and the receiver mutes the signal. You can listen to

signals with any tone other than the speciﬁed tone.

POCKET BEEP AND TONE SQUELCH

■ Tone scan

By monitoring a signal using with pocket beep, tone or DTCS

squelch, you can determine the tone frequency or DTCS

code necessary to open the squelch.

•To change the scanning direction, rotate the main band’s [DIAL].

r When the CTCSS tone frequency or 3-digit DTCS code is

matched, the squelch opens and the tone frequency is

temporarily programmed into the VFO or memory channel.

• The tone scan pauses when a CTCSS tone frequency or 3-digit

DTCS code is detected.

• The decoded CTCSS tone frequency or 3-digit DTCS code is

used for the tone decoder depending on the selected tone con-

dition or type in step w.
