Contents
This scanner has been designed to prevent
reception of illegal transmissions. This is
done to comply with the legal requirement
that scanners be manufactured so as to not
be easily modifiable to pick up those
transmissions. Do not open your scanner's
case to make any modifications that could
allow it to pick up transmissions that it is not
legal to listen to. Doing so could subject you
to legal penalties.
We encourage responsible, legal scanner
use.
Warning:
Modification of this device to
receive cellular radio telephone service
signals is prohibited under
FCC rules
and
under federal law.
