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.

Built-In Automatic Noise Limiter
(ANL)

nearby electrical equipment, such as

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.
