patterns of these signals.

stopwatch method of speed detection, may be in use. Officer

• Safety transmitters may not be commonly used in your area.
• The RX75 PLUS is in AutoMute Mode. See page 5 for details.
• A loose power connection can cause the RX75 PLUS to be
briefly disconnected, and will retrigger the power-on
sequence.

defaults by holding down the City and Mute buttons while you
turn the RX75 PLUS on.
• Check that volume control is ON.
