Introduction 
 
Thank you for purchasing an Albrecht AE92H handheld Scanner. 
The scanner is versatile, compact, and easy to use. You can 
program up to 200 frequencies into the scanners memory. The 
scanner lets you scan transmissions and is preprogrammed with 
service banks for your convenience. You can quickly search 
those frequencies most commonly used by Air band and FM CB, 
without tedious and complicated programming.  
Use your scanner to monitor: 
· Air band 
· FM CB 
as special search bands.

Feature Highlights 
  
Chain Search - lets you enter personal search bands in 10 
locations and search all locations in a chain of frequency bands. 
 
Triple-Conversion Circuitry - virtually eliminates any 
interference from IF (intermediate frequency) images, so you 
hear only the selected frequency. 
 
Channel-Storage Banks - the scanner has 10 banks. You can 
store up to 20 frequencies into each bank (for a total of 200 
frequencies), so you can more easily identify calls. 
 
Two-Second Scan Delay - delays scanning for about 2 
seconds before moving to another channel, so you can hear 
more replies that are made on the same channel. 
 
Lock-Out Function - lets you set your scanner to skip over 
specified channels or frequencies when scanning or searching. 
 
Priority Channels - lets you program one channel in each bank 
(10 in all) and then have the scanner check that channel every 2 
seconds while it scans the bank, so you do not miss 
transmissions on those channels. 
 
Two Service Banks - frequencies are preset in separate aircraft 
and FM CB, to make it easy to locate specific types of calls. 
 
Key Lock - lets you lock the scanners keys to help prevent 
accidental changes to the scanners 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.  
						

							7  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 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 AE92H. 
 
What is Scanning? 
Unlike standard AM or FM radio stations, most two way 
communications do not transmit continuously. Your AE92H 
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 AE92H 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 banks. 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:  
						

							8  · Aircraft 
· Amateur radio 
· PMR users 
· Broadcast AM/FM/TV stations 
· Many other business radio users 
 
When you want to store a conventional system, all you need to 
know is the frequencies they operate on. When you are 
scanning a conventional system, the scanner stops very briefly 
on each channel to see if there is activity. If there isn’t, the 
scanner quickly moves to the next channel. If there is, then the 
scanner pauses on the transmission until it is over. 
 
Simplex Operation 
Simplex systems use a single frequency for both transmit and 
receive. Most radios using this type of operation are limited to 
line-of-sight operation. This type of radio is frequently used at 
construction job sites, and with inexpensive consumer radios 
such as PMR radios. The range is typically 1.5-12 km, 
depending upon the terrain and many other factors. 
 
Repeater Operation 
Repeater systems use two frequencies: one transmits from the 
radio to a central repeater; the other transmits from the repeater 
to other radios in the system. With a repeater-based system, the 
repeater is located on top of a tall building or on a radio tower 
that provides great visibility to the area of operation. When a 
user transmits (on an input frequency), the signal is picked up by 
the repeater and retransmitted (on an output frequency). The 
user’s radios always listen for activity on the output frequency 
and transmit on the input frequency. Since the repeater is 
located very high, there is a very large line of sight. Typical 
repeater systems provide coverage out to about a 40 km radius 
from the repeater location. 
 
Where to obtain more Information 
By itself, this manual really only provides part of what you need 
to know to have fun scanning-how to program and use the 
scanner. 
 
Information on the Internet 
The Internet is a great source for current frequencies and 
information about scanning. 
Many web sites have lists of frequencies for your area. You can 
use a search engine to find and use them. 
Make a list of the agencies you want to listen to, then look up the 
frequencies and systems used by those agencies.

Setting Up Your Scanner 
 
These guidelines will help you install and use your new scanner: 
 
· If your scanner receives interference or electrical noise, 
move the scanner or its antenna away from the 
source. 
· To improve the scanner’s reception, use an optional 
external antenna designed for multiband coverage. 
(You can purchase this type of antenna at a local 
electronics store). If the optional antenna has no cable, 
use 50 Ohm coaxial cable for lead-in. A mating plug 
might be necessary for the optional antennas. 
· Use an optional mono earphone or mono headset with 
proper impedance for private listening. Read the 
precautions on the inside front cover of this Owners 
Manual. 
· Do not use the scanner in high-moisture environments 
such as the kitchen or bathroom. 
· Avoid placing the scanner in direct sunlight or near 
heating elements or vents. 
 
Using Internal Batteries 
You can power your scanner using the supplied rechargeable 
NiMH batteries ( 2 x AA). 
 
Using Rechargeable Batteries 
Before you use NiMH or NiCd batteries the first time, you must 
charge them. It may happen, that the first battery charging may 
not reach the full capacity, but the final capacity will be ok after at 
least 2-3 times charging.  
 
The scanner has a built-in circuit that lets you recharge NiMH or 
NiCd batteries while they are in the scanner.  
To charge the batteries; 
 
1. Make sure the power is turned off. 
2. Slide the battery compartment cover. 
3. Install two batteries in the compartment as indicated by the 
polarity symbols (+ and -) marked inside.

5. Connect the supplied AC adaptor to the scanner’s DC 6 V 
socket to charge the batteries at least for some hours before first 
time use.  
 
Using Non-Rechargeable Batteries 
You can also use two alkaline batteries to power your scanner. 
Before you use alkaline batteries, you must remove the sticker in 
the compartment and move the switch below the sticker to 
REG. ALK. BATT. position. 
 
Notes: 
 
· Use only fresh batteries of the required size and 
recommended type. 
· Always remove old or weak batteries. Batteries can 
leak chemicals that destroy electronic circuits. 
· Do not mix old and new batteries, different types of 
batteries (standard, alkaline, or rechargeable), or 
rechargeable batteries of different capacities. 
 The switch is factory preset to NiMH battery and covered by a sticker. Remove the sticker if You want to use alkaline batteries
