Thank you for purchasing the IC-446S PMR (Private Mobile
Radio) FM transceiver. This PMR FM transceiver meets the European PMR specification (PMR446). This transceiver is designed for those who require top-grade quality, performance
and outstanding reliability under the most demanding conditions.
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 indication. (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
)

■ WATER-RESISTANT* CONSTRUCTION
Water-resistant* construction is employed. Can be used anywhere, 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 communications. In addition, 38 different CTCSS frequencies are available. (p. 11)
)
■ 2 types of “Ring” function
The “Smart-Ring” function and the “Call-Ring” function are available for smart and simple station calls providing a telephonestyle 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
R WARNING! 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.
R WARNING! 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 exhaust quickly. In such case, we recommend to replace the batteries, when the “Low Battery Indicator” appears during
transmission.
The use of non-Icom battery packs/chargers may impair transceiver performance and invalidate the warranty.
Extend the antenna completely when using the transceiver.
• The antenna collapses completely into the transceiver body for carrying purposes.
• The antenna can be adjusted 90 degrees from the regular position
when operating the transceiver in a horizontal position.

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.

GROUP MODE (CTCSS)
Setting the group code
The IC-446S is equipped with 38 group codes. Group mode operation 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:
q Push [MODE] to enter set mode.
•“ --- ” (group mode OFF) appears on
the display.
w Push [UP]/[Y] or [DOWN]/[Z] to select
the desired code number.
e Push [MODE] to set the group code
number.
Cancel the group mode operation:
q Push [MODE] to enter set mode.
• Code number disappears on the display.
w Push [UP]/[Y] or [DOWN]/[Z] to select
“ --- ” (group mode OFF).
e Push [MODE] to cancel the group
mode.
11
NOTE: Only stations with the same
group channel number can be heard during group mode operation, even when the busy indicator appears on the display.
Page 17
GROUP MODE (CTCSS)
✔ 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 operating 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 signals (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 improve 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” radios and as such, transmission range is influenced by the degree 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.
13
• 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 foliage.
