Your Radio Shack TRC-494 is a 40-
channel emergency citizen’s band
weatheradio that is specially de-
signed for emergency situations. It
comes with a handy carrying case so
you can easily move it from one vehi-
cle to another. And, the TRC-494 is
also a 3-channel weatheradio, which
you can use to receive weather infor-
mation 24 hours a day.
You can power the TRC-494 from the
cigarette-lighter socket in any vehicle
that has a 12-volt, negative ground
electrical system. You can also pow-
er the CB from the supplied battery
pack.
Its features include:
CB/Weatheradio Switch —
lets you
quickly switch from the CB to the
weatheradio function.
Emergency Channel 9 Switch —
immediately switches the CB to
Channel 9, the universal emergency
channel.
PLL (Phase-Locked Loop) Fre-
quency Synthesizer — provides re-
liable and exact tuning using a
frequency reference crystal.
Digital Channel-Number Display
— makes it easy to see which chan-
nel is selected.
Range Control — lets you eliminate
background noise when no strong
signals are present.
Built-In Ceramic Filters — provide
superior selectivity and prevent adja-
cent-channel interference.
Built-In Automatic Noise Limiter
(ANL) — reduces noise caused by
nearby electrical equipment, such as
motors or automotive ignition sys-
tems.
External Antenna Jack — lets you
connect the TRC-494 to an external
CB radio antenna.
Note: The TRC-494 comes with a
telescoping antenna that you can at-
tach directly to the CB. You can also
attach it to the supplied magnet-
mount base for use when your vehi-
cle is not moving. If you plan to use
the CB when your vehicle is moving,
we recommend that you purchase a
standard mount antenna.
Important: REACT is a
nationwide 24-hour net-
work that monitors
Channel 9. Switch to
Channel 9 in an emer-
gency, and report the
problem.
Note: REACT might not be available
in all areas.
