This scanner has been designed to prevent the reception of cellular telephone transmissions and the decoding of scrambled transmissions. This is done to comply with the legal requirement that scanners be manufactured so they are not easy to modify to pick up these transmissions. Do not open your scanner’s case to make any modifications that could allow it to pick up transmissions that are illegal to monitor. Modifying or tampering with your scanner’s internal components or using it in a way other than as described in this manual could invalidate your warranty and void your FCC authorization to operate itStep IntroductionIntroduction Frequency50.0-54.0 IntroductionFeature Highlights Feature HighlightsGeneral Dropout Delay – You can set whether the scanner pauses at the end of a transmission to wait for a reply.
