Adjust Squelch
The scanner recognizes signals as transmissions if they exceed a signal strength threshold. Adjusting the squelch sets this threshold level. Increasing squelch requires a signal to be stronger to be seen as a transmission. If you set the squelch too high, you will risk not receiving transmissions that are lower than that threshold. Reducing the squelch allows weaker signals to be accepted. However, if you lower the squelch too much, you will hear white noise all the time.

2.Turn the knob until the interference is gone. Press the scroll control knob again to set the level and return to the previous function.
Adjusting for Interference
There are several options to adjust your scanner to minimize interference. Try:
•Moving the scanner or its antenna away from the source.
•Using an optional external antenna designed for multi- band coverage. (You can purchase this type of antenna at a local electronics store). If the optional antenna has no cable, use
•Moving the scanner from
•Moving the scanner from direct sunlight or near heating elements or vents.
