SPECIAL FEATURES
DELAY
Many agencies use a two-way radio system that has a period
of several seconds between a query and a reply. To avoid
missing a reply, you can program a 2-second delay into any

or frequency with a programmed delay, 
DLY appears and the
scanner continues to monitor that frequency for 2 seconds af-

WIRED/ON-AIR PROGRAMMING
You can program your scanner using data you transfer from
your personal computer to the scanner using an optional PC
cable (called 
wired programming). You can also program your
scanner by receiving data transmitted on a frequency your
scanner can receive (called 
on-air programming).
You can use wired or on-air programming to store the following
data into the scanner:
• Channel number (from 1 to 200)
• Frequency (any frequency the scanner can receive)
• Car number (from 0 to...
