A General Guide To Scanning; Guide To Frequencies - Radio Shack PRO-67 Operation

To save battery power when a channel is manually selected or when the
scanner is in the program mode, the scanner's battery save function
automatically sets the scanner to a standby mode if no button is pressed
for 5 seconds when the squelch is closed (no signal detected). The
battery save function is set to on at the factory. S appears when you
turn it on.
Note:
The scanner's battery save function does not work if the priority
function is on, even if a channel is manually selected.
To turn the battery save function off or back on, turn off the
scanner, then hold down PRIORITY/H/S and turn on the scanner.
OFF SAVE briefly appears when the battery save function is off.
On SAVE briefly appears when the battery save function is on.

A GENERAL GUIDE TO SCANNING

Reception of the frequencies covered by your scanner is mainly
"Line-of-sight." That means you usually cannot hear stations that are
beyond the horizon.
