During mobile operation, DO NOT operate the transceiver without running the vehicles engine. When the transceivers power is ON and your vehicles engine is OFF, the vehicles battery will soon become exhausted.
RWARNING! NEVER connect the transceiver to an AC outlet. This may pose a re hazard or result in an electric shock. RWARNING! NEVER operate the transceiver while driving a vehicle. Safe driving requires your full attentionanything 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.
AVOID using or placing the transceiver in direct sunlight or in
areas with temperatures below 10C or above +60C.
BE CAREFUL! The transceiver will become hot when operating it continuously for long periods.
NEVER connect the transceiver to a power source using reverse
polarity. This will damage the transceiver.
AVOID setting the transceiver in a place without adequate ventilation. Heat dissipation may be affected, and the transceiver may be damaged.
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.
AVOID the use of chemical agents such as benzine or alcohol
when cleaning, as they can damage the transceivers surfaces.
NEVER expose the transceiver to rain, snow or any liquids. The
transceiver may be damaged.
USE Icom microphones only (supplied or optional). Other manufacturers microphones have different pin assignments and may damage the transceiver if attached.

The supplied HM-133s (optional for some versions) [F-1] and [F-2] keys memorize the transceiver conditions. The [UP]/[DN] keys of the standard or an optional microphone (other than the HM-133) can be assigned functions like the function keys on the transceivers front panel.
D [F-1]/[F-2] keys on HM-133
The following conditions in the main band or both left and right bands can be memorized into [F-1] and [F-2] keys, independently. Operating frequency Repeater setting (offset direction and frequency, tone ON/OFF

and frequency)

D [UP]/[DN] keys on a microphones

(other than HM-133)

The following functions are assigned to the [UP]/[DN] keys on the other microphones (HM-118N/TN, etc.) when rst applying power. Default setting [UP] : channel up; push and hold to start scan, push again to stop scan. [DN] : channel down; push and hold to start scan, push again to stop scan. Assigning a function q Turn the power OFF. w While pushing the desired switch on the transceiver and one of either [UP]/[DN] keys on the microphone, turn the power ON.
The function is programmed into the key.

[F-1]/[F-2]

Programming the both bands condition After setting the desired contents of each condition in the both bands, push [FUNC] then push [F-1]/[F-2] for 1 sec.

3 beeps sound.

Recalling the both bands condition Push [FUNC] then [F-1]/[F-2] momentarily. Programming the main band condition Set the desired contents of each condition in the main band, then push [F-1]/[F-2] for 1 sec.
Clearing an assignment q Turn the power OFF. w While pushing the desired [UP] or [DN] key on the microphone, turn the power ON.
Recalling the main band condition Push [F-1]/[F-2] momentarily. 64

I Packet operation

D Data speed
For packet operation, the transceiver can be set to one of two data speeds: 1200 bps (default) or 9600 bps. ] turn power ON to enter initial set q While pushing [SET mode. w Push [SET ] or [LOWPRIO] to select the bPS item. e Rotate the left band [DIAL] to select the desired data speed.

D Cloning error

NOTE: DO NOT push any key on the sub-transceiver during cloning. This will cause a cloning error. When the display as below appears, a cloning error has occurred.
r Push [PWR] to exit initial set mode.
In such a case, both transceivers automatically return to the clone standby condition and cloning must be repeated.
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 transmission in set mode, the microphone signal is automatically cut. Therefore, it is not necessary to disconnect the microphone plug from the connector in this case. When pushing [PTT] during data transmission, data transmission is interrupted and voice signals have priority.

OTHER FUNCTIONS D 1200 bps packet operation
q Connect the transceiver and a TNC as illustrated below.
TNC side q DATA IN w GND e PTT P y P SQL RX AUDIO PTT SQL TX AUDIO GND
Read the instructions supplied with your TNC carefully before attempting packet operation with the transceiver. Pin t AF 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 that many transmissions are failing, re-adjust the modulation level.

t AF OUT

w Set the TNC for transmit. e Set transmit delay on the TNC to 3050. r Adjust the TNC frequency deviation if necessary. When using a deviation meter: Adjust the output of the TNC so that frequency deviation is in the range 3 to 4 kHz. When NOT using a deviation meter: A receiver or transceiver is needed to monitor the transmissioncompare 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.

DUAL BAND FM TRANSCEIVER

Twice the versatility, twice the fun!
V/V, U/U simultaneous receive capability
The IC-2725E is a unique dual band mobile, providing VHF/VHF, UHF/UHF simultaneous receive capability along with VHF/UHF full duplex operation. Simple touch of a button allows you to change the main (transmit) band and sub band.
Independent controls for each band
Operating two bands simultaneously is very simple with Icoms symmetric layout with a wide LCD display showing both band settings in an easy to read side by side format. The IC-2725E provides separate tuning, volume, squelch knobs and function buttons for the left and right side bands. Also, listen to both bands independently through separate left and right band audio jacks.
Dynamic Memory Scan (DMS)
With 212 memory channels, Icoms exclusive Dynamic Memory Scan system gives you exibility over your scanning lists, fully customizable in 10 banks.
Selectable Green and Amber Display.
Photo shows combined controller/main unit setup using optional MB-85.
Compact, remote control head
The control head with the 3.5m (11.5) separation cable is an easy to install two pieces conguration. This conguration offers the exibility of mounting the head while placing the main unit in an out-of-the-way location without any additional cost. Microphone jacks are mounted both on the control head and main unit of the radio!

CTCSS and DTCS

The IC-2725E incorporates 50 CTCSS and 104 DTCS operation along with the tone scan function. Dont miss out on communications because of not having the proper type of tones! The pocket beep feature gives you an audible and visible indicator of an incoming call.

And more

Optional MB-85 allows mounting the controller on the main unit 9600bps packet data terminal (mini-DIN 6-pin connector) 10dB RF attenuator Selectable squelch delay 12 DTMF memory channels (24 digits) Sub band auto mute function Wide/narrow channel spacing Newly adopted MOS-FET power amplier
HM-133, remote control microphone
The backlit HM-133, gives you control of your IC-2725E in the palm of your hand. The Icom exclusive Hot keys (F1/F2) memorize the transceiver full settings. As if switching between two separate radios, VHF/UHF operating frequencies, tone settings as well as the display color and set mode settings are memorized.
