DEFINITION
R WARNING!
Personal injury, fire hazard or electric shock may occur.
CAUTION Equipment damage may occur.
NOTE
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.

I 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 910 o'clock positions.
Set both [VOL] and [SQL] controls to 910 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.
[M/CALL·MW]
[M/CALL·MW]
While pushing both [M/CALL·MW], turn power ON.
While pushing both band's [M/CALL·MW], push [PWR] for 1 sec. to reset the CPU.

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.
Push the desired band's [MAIN·BAND]
Push the desired band's (left or right) [MAIN·BAND] to select the main band. · "Q" appears for the main band.

I Squelch attenuator
The transceiver has an RF attenuator related to the squelch level setting. Approx. 10 dB attenuation is obtained at maximum 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 o'clock position to activate 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.

ating requirements. Low output powers during short-distance communications may reduce the possibility of interference to

5 MEMORY OPERATION
I General description
The transceiver has 212 memory channels including 10 scan edge memory channels (5 pairs), and 2 call channels. Each of these channels can be individually programmed with operating frequency (pgs. 1113), duplex direction (p. 23) and offset (p. 27), subaudible tone encoder or tone squelch and its tone frequency (pgs. 23, 25, 51, 52) and skip information* (p. 44). In addition, a total of 10 memory banks, A to J, are available for usage by group, etc.

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 microphone plug from the connector in this case. · When pushing [PTT] during data transmission, data transmission is interrupted and voice signals have priority.

· 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 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.

· 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.

OTHER FUNCTIONS 11
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-p0.5 V p-p (0.10.25 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 transmit 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.
D Packet operation band selection
Both bands, or either the left or right band only, can be specified for packet operation to suit your preference.
q While pushing [SET· ] turn power ON to enter initial set
mode. w Push [SET· ] or [LOW·PRIO] to select the `PAC' item.
e Rotate the left band [DIAL] to select the desired band from
auto (At; default), left (L) and right (r).
