Features
Your new PRO-405 Desktop 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 onetouch search key—no complicated programming required.
Your new scanner gives you direct access to over 26,000 frequencies, including
those used by police and fire departments, FM broadcast, ambulance services,
aircraft, and amateur radio services.
Your PRO-405 scanner also has these special features:
Service Banks –
easily locate types of calls by searching preprogrammed
frequencies in separate marine, fire/police, aircraft, ham, FM broadcast, 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 power.
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.
5
Features
Data Cloning – transfer the programmed data to another PRO-405 scanner.
Real-time Signal Strength Indicator – shows relative strength of received
signals.
Liquid-Crystal Display (LCD) –
easy to view and change programming
information.
Telescopic Antenna –
provides good reception of strong local signals. You can
also connect an external antenna for improved reception of distant or weak
signals.
Your PRO-405 scanner can receive these bands:
Frequency Range Types of Transmissions
29–54 MHz 10-Meter Ham, VHF Lo, 6-Meter Ham
87.3–107.9 MHz FM Broadcast
108–136.99166 MHz Aircraft
137–174 MHz Military Land Mobile, 2-Meter Ham, VHF Hi
380–512 MHz UHF Aircraft, Federal Government, 70-cm Ham, UHF
Standard, UHF “T”
n Note: See “Specifications” on page 32 for more information about frequency
steps.

Features
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.
When you find a frequency, you can store it into a programmable memory
location called a channel, which is grouped with other channels in a channel-
storage bank. You can then scan the channel-storage banks to see if there is
activity on the frequencies stored there. Each time the scanner finds an active
frequency, it stays on that channel until the transmission ends.
Channel Storage Banks
To make it easier to identify and select the channels you want to listen to, your
scanner divides the channels into 10 banks (1 to 10) with 20 channels each,
for a total of 200 channels. You can use each channel-storage bank to group
frequencies, such as those used by the police department, fire department,
ambulance services, or aircraft.
For example, you could program the frequencies used by your local police
department starting with Channel 1 (the first channel in bank 1) and program
the fire department frequencies starting with Channel 21 (the first channel in
bank 2).
Service Banks
The scanner is preprogrammed with the frequencies allocated to marine, fire/
police, aircraft, ham radio, FM broadcast and weather services. This is handy for
quickly finding active frequencies instead of searching through an entire bank
(see “Service Bank Search” on page 17).
