Racing Electronics SC150 - Manual (Page 27)

Birdies
All scanners are subject to receiving undesired signals or
birdies. If your scanner stops during SEARCH Mode and
no sound is heard, it may be receiving a birdie. Birdies are
internally generated signals inherent in the electronics of
the scanner. Use the Search Skip feature to skip the
unwanted frequencies.
Proper Care of Your Scanner
Use only the AC Adapter/Charger that came with your
scanner.
Do not leave the AC Adapter/Charger plugged in for long
periods.
Avoid placing the scanner in direct sunlight or near heating
elements or vents.
Also, do not subject the scanner to continuous sub-zero
temperatures. If the scanner is exposed to temperatures
below -5°F or above 140°F, the liquid crystal display may
temporarily cease to function properly, or can become
permanently damaged.
