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 different kind of Batteries” and “Using rechargeable

Batteries” on page 9 /10 and “Connecting the Antenna” on page

11 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 AE69-2H.

What is Scanning?

Unlike standard AM or FM radio stations, most two way

communications do not transmit continuously. Your AE69-2H

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

transmission.

What is Searching?

The AE69-2H can search for active frequencies. This is different

from scanning because you are searching for frequencies that

have not been programmed into the scanner. When you select

frequency bands to search, the scanner searches for any active

frequency within the lower and upper limits you specify. When

the scanner finds an active frequency, it stops on that frequency

as long as the transmission lasts. If you think the frequency is

interesting, you can program it into one of the memories. If not,

you can continue to search.

Conventional Scanning

Conventional scanning is a relatively simple concept. Each

group of users in a conventional system is assigned a single

frequency (for simplex systems) or two frequencies (for repeater

systems). Any time one of them transmits, their transmission

always goes out on the same frequency. Up until the late 1980’s

this was the primary way that radio systems operated.

Even today, there are many 2-way radio users who operate

using a conventional system:

• Aircraft (not to be received with this scanner model)

• Amateur radio

• PMR users
