i446S

FOREWORD

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

)

i

■ 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.
