Understanding Your Scanner
Once you understand a few simple terms used in this
manual and familiarize yourself with your scanner’s
features, you can put the scanner to work for you.
Simply determine the type of communications you want
to receive, then set the scanner to scan them.
A
frequency
is the receiving signal location (expressed
in kHz or MHz). To find active frequencies, use the
search
function or consult an online resource such
as www.radioreference.com. You can also search the
Service Banks
, which are preset groups of frequencies
categorized by type of service.
When you find a frequency, you can store it into a
programmable memory location called a
channel
,
Features
Your new PRO-404 Handheld Scanner lets you scan
conventional transmissions and is preprogrammed with
search banks of the most common frequencies used
by public service agencies. Service Banks are accessed
by pressing a one-touch search key—no complicated
programming required.
Your new scanner gives you direct access to over 25,000
frequencies, including those used by police and fire
departments, ambulance services, aircraft, and amateur
radio services.
Your PRO-404 scanner also has these special
features:
Signal Stalker II –
a powerful tool to rapidly detect,
monitor, and store frequencies from nearby radio
transmissions.
Service Banks –
easily locate types of calls by searching
preprogrammed frequencies in separate marine, fire/
police, aircraft, ham, and weather banks.
Display Backlight –
makes the display easy to read in
low-light situations.
Lock-out Function –
skip over specified channels or
frequencies when scanning or searching.
Ten Channel-Storage Banks –
group and store 20
channels in each bank (200 total channels).
Tune –
tune to new and unlisted frequencies starting
from a specified frequency.
SAME/FIPS Weather Alert –
displays the weather
event and sounds an alert for the specific cities or
counties you choose.
Memory Backup –
frequencies remain stored in
memory for an extended time even without batteries.
Scan Delay –
delays scanning for two seconds before
moving to another channel in order to hear replies.
Priority Channel –
set the scanner to check one
channel every two seconds while scanning.
Data Cloning –
transfer the programmed data to
another PRO-404 scanner.
