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.
