FOREWORD
READ ALL INSTRUCTIONS carefully and completely
before using the transceiver.
SAVE THIS INSTRUCTION MANUAL This in-
struction manual contains important operating instructions for
the IC-Q7A/E.
EXPLICIT DEFINITIONS
The explicit definitions below apply to this instruction manual.
CAUTIONS
R WARNING! NEVER hold the transceiver so that the
antenna is very close to, or touching exposed parts of the
body, especially the face or eyes, while transmitting. The
transceiver will perform best if the microphone is 5 to 10 cm
away from the lips and the transceiver is vertical.
R WARNING! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels.
Hearing experts advise against continuous high volume op-
eration. If you experience a ringing in your ears, reduce the
volume level or discontinue use.
DO NOT push the PTT when not actually desiring to trans-
mit.
DO NOT operate the transceiver near unshielded electrical
blasting caps or in an explosive atmosphere.
AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures below –10°C (+14°F) or above
+60°C (+140°F).
Place unit in a secure place to avoid inadvertent use by chil-
dren.
WORD
R
WARNING
CAUTION
NOTE
DEFINITION
Personal injury, fire hazard or electric
shock may occur.
If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.
Equipment damage may occur.
Versions of the IC-Q7E which display CEon the serial number
seal, comply with the essential requirements of the 89/336/EEC
directive for Electromagnetic Compatibility.
ii
Even when the transceiver power is OFF, a slight current still
flows in the circuits. Remove batteries from the transceiver
when not using it for a long time. Otherwise, the installed bat-
teries will become exhausted.
For U.S.A. only
CAUTION: Changes or modications to this device, not ex-
pressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.

FREQUENCY AND CHANNEL SETTING
VFO and memory/call channels
This transceiver has 2 normal operating modes: VFO mode
and memory (call) mode.
VFO mode is used for setting a desired frequency within the
band range.
Push [V/M] once or twice to select
VFO mode.
Memory (call) mode is used for operation of memory (call)
channels which have programmed frequencies.
Push [V/M] once or twice to select
memory mode.
To program a memory, refer to p. 12.
Push [CALL(LOCK)] to select a call
channel.
What is VFO?
VFO is an abbreviation of Variable Frequency Oscillator. Fre-
quencies for transmitting and receiving are generated and
controlled by the VFO.
Operating band selection
The transceiver can receive the 50 MHz band, VHF avionics
band, 144 MHz band, 300 MHz band, 400 MHz band, 800
MHz band* or 1200 MHz band.
Push [BAND] several
times to select the de-
sired band.
When a memory or call
channel is selected, the
first push of [BAND] se-
lects VFO mode (and
transfers the memory or
call channel contents).
When pushing [PTT],
OFF appears indicating
the frequency is outside
the 144/400 MHz ama-
teur bands.

not be received with
the U.S.A. version.

RIT function
To compensate for the off frequency of a transmitting station,
the transceiver has receive incremental tuning for receiving
frequencies above 835 MHz.

BASIC OPERATION
Receive mode selection
Receive modes are determined by the physical properties of
the radio signals. The transceiver has 3 receive modes: FM,
AM and WFM modes. The mode selection is stored indepen-
dently in each band and memory channels.

MHz) and WFM is used for FM broadcast stations (76107.9
MHz).
When pushing [PTT], a beep tone sounds indicating the
mode is not FM mode. The transceiver cannot transmit in
AM or WFM mode.
DSetting the receive mode

Unwanted frequencies can be skipped and programmed as
skip channels when full scan, band scan or programmed scan
is pausing.

tion as described at right.
w Start full scan, band scan or pro-
grammed scan. (p. 16)

Non-programmed memory channels (blank channels) are used
for skip frequency programming in reverse sequence.
Do not release [V/M] before 2 sec., otherwise, scan stops and
the transceiver enters memory programming condition.
To scan the skip frequency after programming, cancel the skip
information (p. 18) or clear the memory channel (p. 14).
When the frequency skip function is turned OFF (P SKIP
does not ash), the paused frequency overwrites the pre-
viously selected memory channel.

set mode. In this case, the frequencies will not be skipped
even if skip information is programmed and P SKIPwill not
blink during full scan, band scan or programmed scan.

the receive frequency by the offset frequency. (p. 24) It is con-
venient to program repeater information into memory chan-
nels. (p. 12)
q Set the receive frequency (repeater output frequency).
w Set the shift direction of the transmit frequency. (DUP or
DUP; see the next section for details.)
When the auto repeater function is in use (U.S.A. version only),
this selection and step e are not necessary. (p. 25)
e Activate the subaudible tone encoder, according to re-
peater requirements.
Refer to the next page for tone frequency settings.

Tone scan
The transceiver can detect the subaudible tone frequency in a

frequency required to access the repeater.

To change the scanning direction, rotate [DIAL].
e When the tone frequency is decoded, the set mode con-
tents are programmed with the tone frequency.
The tone scan pauses when a tone frequency is detected.
The decoded tone frequency is used for the repeater tone fre-
quency or tone squelch frequency, depending on the the tone
squelch ON/OFF setting.

120 min., 90 min., 60 min., 30 min. and OFF can be speci-
fied. The specified period is retained even when the trans-
ceiver is turned OFF by the auto power-off function.To cancel
the function, select OFF in step e below.

The dial speed acceleration automatically speeds up the tun-
ing dial speed when rotating the [DIAL] rapidly.

The lock function prevents accidental frequency changes and
accidental function access.
While the lock function is ON, [POWER], [VOL], [SQL] and
[PTT] can still be accessed. Accessible switches can be set to
1 of 4 groups in expanded set mode.

OTHER FUNCTIONS
Channel indication mode
Channel indication mode is used to simplify operation. In this
mode only pre-programmed memory channel numbers are
displayed and functions are limited ([POWER], [PTT], [SQL],
[VOL], [LOCK], scanning and the tuning dial are functional).
q Select memory mode with [V/M].
w Push [V/M] for 2 sec. to enter expanded set mode.
e Rotate [DIAL] until CH appears.
Turn the expanded set mode ON for selection. (p. 28)
r While pushing [FUNC], rotate [DIAL] to turn the channel
indication ON or OFF.
t Push [V/M] to exit set mode.
To return to normal indication, turn this function OFF in
step r above.
Frequencies must be programmed into memory channels
in advance.
Partial reset
If you want to initialize the operating conditions (VFO fre-
quency, VFO settings, set mode contents) without clearing the
memory contents, a partial resetting function is available for
the transceiver.
While pushing [FUNC] and [V/M], turn power ON to par-
tially reset the transceiver.
All reset
Reset the CPU before operating the transceiver for the rst
time, or when the internal CPU malfunctions.
While pushing [FUNC], [BAND] and [V/M], turn power ON
to reset the CPU.
•“CLEAR appears when resetting the CPU.
CAUTION:Resetting the CPU returns all programmed
contents to their default settings.
