Key Lock - lets you lock the scanner's keys to help prevent
accidental changes to the scanner's programming.
Direct Access - lets you directly access any channel.
Display Backlight - makes the scanner easy to read in low-light
situations.
Flexible Antenna with BNC Connector – provides adequate
reception in strong signal areas and is designed to help prevent
antenna breakage. Or, you can connect an external antenna for
better reception.
Memory Backup - keeps the frequencies stored in memory for
an extended time if the scanner loses power.
Two Power Options - let you power the scanner using internal
batteries or external AC power using the included AC adapter.
Key Confirmation Tones - the scanner sounds a tone when
you perform an operation correctly, and an error tone if you
make an error.
Battery Low Alert - warns you when battery power gets low.
About this Manual
The screen displays used in this manual are representations of
what might appear when you use your scanner. Since what you
see depends on the frequencies for your area and the settings
you select, you might notice some differences between what is
in this manual and what appears on your scanner.
To get the most from this manual, review the contents to become
familiar with the basic functions available. If you are new to
scanning, be sure to read the next chapter for a quick
background on the technology behind the hobby. The first thing
you’ll need to do is install batteries in the scanner. Then you
need to connect the included antenna to the scanner. See
“Using Internal Batteries” on Page 9/10 and “Connecting the
Antenna” on Page 12 if you need any help doing this.
Understanding Scanning
This section provides you with background on how scanning
works. You don’t really need to know all of this to use your
scanner, but some background knowledge will help you get the
most from your AE 72 H.
What is Scanning?
Unlike standard AM or FM radio stations, most two way
communications do not transmit continuously. Your AE 72 H
scans programmed channels until it finds an active frequency,
then stops on that frequency and remains on that channel as
long as the transmission continues. When the transmission ends,
the scanning cycle resumes until the scanner receives another
