INSTRUCTION MANUAL

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-F4SR.
EXPLICIT DEFINITIONS
The explicit definitions below apply to this instruction manual.
CAUTIONS
RWARNING! 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.
RWARNING! 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.
NEVER connect the transceiver to an AC outlet or to a
power source of more than 16 V DC. Such a connection will
damage the transceiver.
NEVER connect the transceiver to a power source that is
DC fused at more than 5 A. Accidental reverse connection will
be protected by this fuse, higher fuse values will not give any
protection against such accidents and the transceiver will be
ruined.
NEVER attempt to charge alkaline or dry cell batteries.Be-
ware that external DC power connections will charge batteries
inside the battery case.This will damage not only the battery
case but also the transceiver.
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-F4SR which display “CE”on the serial number
seal, comply with the essential requirements of the 89/336/EEC
directive for Electromagnetic Compatibility.

ii
DO NOT push the PTT when not actually desiring to trans-
mit.
DO NOT allow children to play with any radio equipment
containing a transmitter.
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 –20°C or above +55°C.
The use of non-Icom battery packs/chargers may impair
transceiver performance and invalidate the warranty.
Even when the transceiver power is OFF, a slight current still
flows in the circuits. Remove the battery pack or case from
the transceiver when not using it for a long time. Otherwise,
the battery pack or installed dry cell batteries will become ex-
hausted.

speed up the scanning interval.
In addition, the auto channel function is available for standby
convenience. (p. 11)

or similar tones.10 kinds of ring tones are available.
qSelect the desired channel with the [Y]/[Z] switches.
wPush [ ] for a desired time to call the waiting station.
•“S”appears while transmitting a ring tone.
•The ringer tones are repeatedly transmitted when this key is
pushed and held.
eWaiting station receives the ringer tones.
rOperate the transceiver in the normal way.
■Ringer pattern
10 ringer patterns are available. Select the desired ringer pat-
tern as follows:
qWhile pushing [Z] + [ ], turn power ON to enter ringer
pattern set mode.
•“RG”and the selected ringer pattern
number appear.
wPush [Y] or [Z] to select the
ringer pattern.
•The selected pattern is played once.
eTurn power OFF to exit set
mode.
■Ringer timer
Ringer time is the minimum transmission time of the ringer
tones when the auto channel function is in use. 0 to 16 sec.in
1 sec. steps can be programmed.
qWhile pushing [Y] + [?], turn power ON to enter set mode.
•Set mode is not available depending on dealer setting.
wPush [?] several times until “Rt”appears.

ing period of the auto channel function. (p. 11) The recom-
mended ringer time depends on the number of receive
stations:
2 or 3 channels 2 sec.
4 or 5 channels 3 sec.
6 or 7 channels 4 sec.

■Auto channel function
The auto channel function automatically checks for calling sig-
nals or ringer signals on all or select channels.
If you hear ringer tone, specified in set mode, you can answer
the call by simply pushing the [PTT] switch. It is not neces-
sary to select a channel first.
qPush [f(AUTO CH)] to turn the auto channel function ON.
•“A”appears and scan starts.
wWhen receiving a ringer tone, push [PTT] to answer.
eTo call a waiting station, push [ ] to transmit a ringer
tone.
•To call a waiting station by voice, push [PTT] until beep tones
sound (for longer than the ringer time), then speak into the mi-
crophone.
rWhen the auto reset timer is turned OFF, push [f(AUTO
CH)] to restart the auto channel function.
tPush [f(AUTO CH)] to cancel the function.
■Auto reset timer
Auto reset time is the period before the auto channel function
restarts after a busy signal disappears and in which no oper-
ation is performed while the auto channel function is in use.
5 to 60 sec. in 5 sec. steps or OFF can be programmed.
qWhile pushing [Y] + [?], turn power ON to enter set mode.
•Set mode is not available depending on dealer setting.

6TONE SQUELCH/DTCS
■ Operation
By default, the transceiver uses a CTCSS/DTCS squelch sys-
tem. The CTCSS tone squelch/DTCS opens only when re-
ceiving a signal containing a matching tone.You can silently
wait for calls from group members using the same tone.
qPush [Y] or [Z] to select the desired channel.
wSet the desired tone or code as described at right.
ePush [?] to turn the receive tone squelch ON.
•“ ”disappears when the tone squelch is turned ON.
•Tone squelch or DTCS is always turned ON for some versions.
rWhen the received signal includes a matching tone,
squelch opens and the signal can be heard.
•When the received signal’s tone does not match, tone squelch
does not open, however, the S-indicator shows signal strength.
•To open the squelch temporarily, push and hold [?].
NOTE:The transceiver has 50 CTCSS tone frequencies
and consequently their spacing is narrow compared with
units having 38 tones. Therefore, some tone frequencies
may receive interference from adjacent tone frequencies.
Tone frequencies or DTCS code settings are automatically
stored in memory channels for easy recall.
■Setting a tone or code
50 CTCSS tones and 84 DTCS codes are available.
qPush [Y] or [Z] to select a channel.
wPush [f(CODE)].
•Current tone or code appears.
ePush [Y] or [Z] to select the
CTCSS tone frequency or
DTCS code.
•“–” appears when an inverse
DTCS code is selected.
rPush [f(CODE)] to exit.

6TONE SQUELCH/DTCS
■Pocket beep operation
By default, the transceiver uses a CTCSS/DTCS squelch sys-
tem. Using this system, you can determine that someone has
called while you were away from the transceiver—much like a
“common pager.”
DWaiting for a call from a specific station
qSelect the desired channel with the [Y]/[Z] switches.
•If “”appears, push [?] to turn the tone decoder ON. (p.12)
wSet the desired tone or code.
•See p. 12 for programming information.
ePush [f(PO BEEP)] to activate the pocket beep. (p.14)
•“ë”appears in the function display.
rWhen a signal with the correct tone is received, the trans-
ceiver emits beep tones and flashes “ë.”
tPush [PTT] to answer or push [f(PO BEEP)] to stop the
beeps and flashing.

wSet the desired tone or code.
ePush [PTT] to call the waiting station.
rWait for the answer back call.
■Pocket beep pattern
The pocket beep pattern, when receiving a matched CTCSS
tone/DTCS code, can be selected from 6 patterns.
