frequently asked questions

Q: My scanner isn’t working at all. How do I turn it on?

A: The scanner might not be receiving power. Make sure the batteries are installed correctly and are good (if you installed alkaline batteries) or fully charged (if you installed rechargeable batteries). See “powering your scanner” on Page 5 for more information.

If the batteries are good, make sure the AC adapter’s or DC adapter’s barrel plug is fully inserted into the scanner’s 6V 300 mA jack. See “using AC power” on Page 10 for more information.

If the scanner is receiving power, make sure it is turned on. See “turning on the scanner and setting squelch” on Page 25 for more information.

Q: My scanner is on but won’t scan. How do I get it to scan?

A: Make sure the squelch is adjusted correctly. See “turning on the scanner and setting squelch” on Page 25 for more information.

If the squelch is set correctly, you might not have stored frequencies into any channels or only one channel. You must store at least two frequencies for the scanner to scan. See “storing known frequencies into channels” on Page 25 for more information.
