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 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 be-
come 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 dam-
age the transceiver if attached.

Squelch attenuator
The transceiver has an RF attenuator related to the squelch
level setting. Approx. 10 dB attenuation is obtained at maxi-
mum setting.
The squelch attenuator allows you to set a minimum signal
level needed to open the squelch. The attenuator function can
be deactivated in initial set mode.
Rotate [SQL] clockwise past the 12 oclock 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.

IMPORTANT! (for 50/35 W transmission):
The IC-2725E is equipped with protection circuit to protect
the power amplifier circuit from high SWR (Standing Wave
Ratio) and temperature. When a high SWR antenna or no
antenna is connected, or when the transceiver temperature
becomes extremely high, the transceiver reduces transmit
output power to 15 W (approx.) automatically.

General
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 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 ow 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).

DD 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 inde-
pendently.
This item appears when set mode is accessed from left band
only.

DD 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 (non-
main band) setting.
It is helpful in case the transceiver receiving heterodyne spu-
rious 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.

power ON to partially reset the desired band (left or right).
Hint!
When pushing both [V/MHz SCAN] and turning the power
ON, partially reset both bands at the same time.
ALL reset
The function display may occasionally display erroneous in-
formation (e.g. when first applying power). This may be
caused externally by static electricity or by other factors.
If this problem occurs, turn power OFF. After waiting a few
seconds, turn power ON again. If the problem persists, per-
form the following procedure.
Partial resetting is also available. See left for details.

mode.
w Push
[SET]
or [LOW PRIO] to select the bPS item. ‘ ’
e Rotate the left band [DIAL] to select the desired data
speed.
r Push [PWR] to exit initial set mode.
For 1200 bps operation—
Disconnect the microphone plug from the microphone
connector during data transmission, otherwise the data
signal and voice signal are simultaneously transmitted.
For 9600 bps operation—
When the transceiver is set for 9600 bps data transmis-
sion in set mode, the microphone signal is automatically
cut. Therefore, it is not necessary to disconnect the mi-
crophone plug from the connector in this case.
When pushing [PTT] during data transmission, data trans-
mission is interrupted and voice signals have priority.

A receiver or transceiver is needed to monitor the trans-
missioncompare the received audio output level when
receiving a TNC modulated signal with high level voice
signals using the microphone. Then adjust the TNC mod-
ulated signal to a lower level than the voice modulated
signal.
Read the instructions supplied with your TNC carefully
before attempting packet operation with the transceiver.
Pin tAF OUT is for 1200 bps operation only. This pin
cannot be used for 9600 bps operation.
Over modulation may degrade signal quality. If you nd
