Radio Shack PRO-71 Owner's Manual page 5

This scanner has been designed to prevent reception of illegal trans-
missions. This is done to comply with the legal requirement that scan-
ners be manufactured so as to not be easily modifiable to pick up those
transmissions. Do not open your scanner's case to make any modifica-
tions that could allow it to pick up transmissions that it is not legal to lis-
ten to. Doing so could subject you to legal penalties.
We encourage responsible, legal scanner use.
