FOREWORD
Thank you for purchasing the IC-446S PMR (Private Mobile
Radio) FM transceiver. This PMR FM transceiver meets the Eu-
ropean PMR specification (PMR446). This transceiver is de-
signed for those who require top-grade quality, performance
and outstanding reliability under the most demanding condi-
tions.
FEATURES
●
Free of user-license and applications
●
All 8 PMR channels are available
●
38 convenient group channels
●
Water-resistant construction
●
500 mW (ERP) High output power
■ATS (Automatic Transponder System)
This convenient function automatically checks station availability
within the operating range, and alerts you via function display in-
dication. (p. 17)
In addition, a manual transponder is also available for “GROUP
MODE” operation to check availability of stations in a specified
group within the operating range. In this case, the transceiver
alerts you via beeps. (p. 14)

ii
■WATER-RESISTANT* CONSTRUCTION
Water-resistant* construction is employed. Can be used any-
where, anytime.
*Meets JIS water-protection specification grade 4.
■GROUP MODE (BUILT-IN CTCSS: Continuous Tone
Coded Squelch System)
CTCSS encoder/decoder are standard, providing quiet stand-by.
Audio (voice) signals are output only when a signal with matched
CTCSS tone signal is received—very helpful for group commu-
nications. In addition, 38 different CTCSS frequencies are avail-
able. (p. 11)
■2 types of “Ring” function
The “Smart-Ring” function and the “Call-Ring” function are avail-
able for smart and simple station calls providing a telephone-
style ring when called. 10 different ringing tones are available.

IMPORTANT
READ ALL INSTRUCTIONS carefully and completely
before using the transceiver.
SAVE THIS INSTRUCTION MANUAL–This instruction
manual contains important operating instructions for the
IC-446S PMR FM transceiver.
CAUTIONS
RWARNING! NEVER hold the transceiver so that the an-
tenna 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 (2 to 4 in.)
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.
DO NOT push the PTT when not actually desiring to transmit.
DO NOT modify the transceiver for any reason.
AVOID using or placing the transceiver in direct sunlight or in
areas with temperatures below –20°C (–4°F) or above +55°C
(+131°F). In an extreme low temperature environment (around
–20°C), the capacity of Alkaline or dry cell batteries may ex-
haust quickly. In such case, we recommend to replace the bat-
teries, when the “Low Battery Indicator” appears during
transmission.
The use of non-Icom battery packs/chargers may impair trans-
ceiver performance and invalidate the warranty.

BATTERY PACKS 3
7
‘‘Battery pack charging
The optional BP-202 BATTERY PACK includes rechargeable Ni-Cd
batteries and can be charged approx. 300 times. Charge the battery
pack before first operating the transceiver or when the battery pack
becomes exhausted.
If you want to be able to charge the battery pack more than 300
times, the following points should be observed:
1. Avoid overcharging. The charging period should be less than 48
hours.
2. Use the battery until it becomes almost completely exhausted
under normal conditions. We recommend battery charging just
after transmitting becomes impossible.
‘‘Battery pack life
If your battery pack seems to have no capacity even after being
fully charged, completely discharge it by leaving the power ON all
day. Then, fully charge the battery pack again.
If the battery pack still does not retain a charge (or very little), a new
battery pack must be purchased.
‘‘Battery pack CAUTION
NEVER short terminals of the battery pack (or charging terminals of
the transceiver). Also, current may flow into nearby metal objects,
so be careful when placing battery packs ( or the transceiver) in
handbags, etc. Simply carrying with or placing near metal objects
such as necklace, etc. causes shorting. This will damage not only
the battery pack but also the transceiver.

BASIC OPERATION 4

‘‘Power ON
➥Push [POWER] for 1sec. to turn the
power ON.
• The power on indicator and oper-
ating channel number appear on
the display.
‘‘Adjusting the volume
qPush and hold [MODE] for
1sec. to open the squelch.
• Busy indicator appears on
the display while the squelch is
open.
wAdjust the audio to a suitable level
using [VOL].
ePush and hold [MODE] for 1sec. to
close the squelch.
✔What is squelch?
A squelch circuit allows you to mute undesired noise while re-
ceiving no signal and emit audio while receiving signals.
This provides quiet standby. The [MODE] key changes the
squelch setting. This is useful to listen to weak signals that do
not open the squelch.

‘‘Selecting the operating channel
Push [UP]/[Y] or [DOWN]/[Z] keys sev-
eral times until the desired operating
channel number appears on the dis-
play.
• While pushing and holding [UP]/[Y] or
[DOWN]/[Z] keys, the displayed chan-
nel changes continuously until chan-
nel number “ 1 ” appears.
If you want to keep the automatic se-
lection, release the [UP]/[Y] or
[DOWN]/[Z] keys then push and hold them again.
• When displayed channel stops at channel number “1”, a warning
beep is emitted.
NOTE:
• The transceiver has 8 operating frequency channels.
• The selected channel is memorised when you turn off the
transceiver.
• The transceiver has an auto power save function to conserve
the battery power. The power save function activates automat-
ically when no signal is received for 5 sec.

wSelect a desired operating channel.
When a signal is received:
•Squelch opens and audio is emitted
from the speaker.
•Further adjustment of [VOL] may be
necessary at this point.
•“BUSY”indicator appears on the dis-
play.
ePush and hold [PTT] to transmit then
speak into the microphone.
•Do not hold the transceiver too close
to your mouth or speak too loudly.
This may distort the signal.
•The transmit indicator “”appears

rRelease [PTT] to return to receive.
Time-Out Timer (TOT)
The transceiver has time-out timer function. This function pre-
vent continuous, extend transmissions. This timer turns a trans-
mission OFF 3 min. after it starts.
A warning beep sounds 10 sec. before the limit is reached and
the time-out timer turns OFF the transmission automatically. The
end beep emits to announce the end of the transmission.

6GROUP MODE (CTCSS)
‘‘Setting the group code
The IC-446S is equipped with 38 group codes. Group mode oper-
ation provides communication with silent standby since you will only
receive calls from group members using the same group number.
First of all, set the same group code number for all group member’s
transceivers.
Turn ON the group mode operation:
qPush [MODE] to enter set mode.
•“--- ”(group mode OFF) appears on
the display.
wPush [UP]/[Y] or [DOWN]/[Z] to select
the desired code number.
ePush [MODE] to set the group code
number.
Cancel the group mode operation:
qPush [MODE] to enter set mode.
•Code number disappears on the dis-
play.
wPush [UP]/[Y] or [DOWN]/[Z] to select
“--- ”(group mode OFF).
ePush [MODE] to cancel the group
mode.
NOTE: Only stations with the same
group channel number can be heard during group mode opera-
tion, even when the busy indicator appears on the display.

GROUP MODE (CTCSS) 6
13
✔What is CTCSS (Continuous Tone Coded Squelch Sys-
tem) GROUP MODE ?
CTCSS (Continuous Tone Coded Squelch System) GROUP
MODE allows communication with silent stand by. Only signals
containing your group code can open the squelch.
This conveniently eliminates unwanted audio and is useful in
group activities or security related activities where unwanted
output can be a problem. Note that CTCSS group mode is not
private—anyone can receive your calls.
The IC-446S is equipped with 38 tone codes for CTCSS
GROUP MODE use. Selecting a code applies it to all 8 oper-
ating channels. Each push of [PTT] superimposes your group
code over your transmit signal; and, only signals containing the
same code can open your squelch. To temporarily hear all sig-
nals (including noise) push and hold [MODE]. Do not use
CTCSS GROUP MODE if you want to be able to hear signals
on all channels.

✔Talk Range
The IC-446S is designed to maximize performance and im-
prove transmission range in the field. However, the single
most important factor in transmit range (talk power) is your
surrounding environment. These radios are “line of sight”ra-
dios and as such, transmission range is influenced by the de-
gree to which you can “see”the other communicating party.
Large concrete structures and heavy foliage or transmission
from inside a building or vehicle will reduce your talk power.
•Optimal range: wide, open areas free of obstructions.
•Medium range: large buildings or trees blocking your line of
sight.
•Minimum range: mountainous areas or areas of heavy fo-
liage.
