USING THE ROTARY
CONTROL
The rotary control has three modes
that you select using the
FREQ/CHAN-
LOCK
button. To select the control’s
mode, repeatedly press
FREQ/CHAN-
LOCK
until the scanner displays the
desired mode.
FREQ
— the rotary control steps
through frequencies during a search.
CHAN
— the rotary control steps
through the programmed channels.
LOCK
— the rotary control does not
operate. Use this setting to help pre-
vent accidentally changing the chan-
nel or frequency.
STORING FREQUENCIES
You can store up to 200 frequencies
into your scanner’s channels. Good
frequency references are Ra-
dioShack’s “Police Call Guide includ-
ing Fire and Emergency Services,”
“Official Aeronautical Frequency Di-
rectory,” and “Maritime Frequency Di-
rectory.” These directories are
updated every year, so be sure to get
a current copy.
If you do not have a frequency refer-
ence for your area, you can use a limit
or direct search to find transmissions.
See “Searching For and Temporarily
Storing Active Frequencies” on
Page 19 or “Guide to the Action
Bands” on Page 34.
Follow these steps to manually store
frequencies.
