Precautions
Before you use this scanner, please read and observe the
following.
EARPHONE WARNING!
Be sure to use the supplied mono headphone. Use of an
incorrect earphone or stereo headset with lower impedance
might be potentially hazardous to your hearing, when tuned
to high volume settings.
The output of the phone jack is monaural, but you will hear it
in both headphones of a stereo headset.
Set the volume to a comfortable audio level coming from the
speaker before plugging in the monaural earphone or stereo
headset of the proper impedance (32 Ohms recommended).
Otherwise, you might experience some discomfort or
possible hearing damage if the volume suddenly becomes
too loud because of the volume control or squelch control
setting. This might be particularly true of the type of
earphone that is placed in the ear canal.
WARNING!
Uniden does not represent this unit to be waterproof. To

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.
How the Scanner’s Controls Are

become familiar with the basic functions available.
If you are new to scanning, be sure to read the chapter
“Understanding Scanning” for a quick background on the
technology. 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 pages 17-20 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 AE230H.
Understanding the Scanner’s Memory
Your scanner’s memory is organized in an architecture
called Dynamic Allocated Channel memory. This type of
memory is organized differently and more efficiently than
the bank/channel architecture used by traditional scanners.
Dynamic Allocated design matches how radio systems
actually work much more closely, making it easier to
program and use your scanner and determine how much
memory you have used and how much you have left.
Instead of being organized into separate banks and
channels, your scanner’s memory is contained in a pool.
You simply use as much memory as you need in the pool to
store as many frequencies and alpha tags as you need.
No memory space is wasted, and you can tell at a glance
how much memory you have used and how much remains.

13
What is Scanning?
Unlike standard AM or FM radio stations, most two-way
communications do not transmit continuously. Your AE230H
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 AE230H can search each band and up to 10 frequency
bands together to find 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 the scanner’s memory. If not, you can continue to
search.
What is CTCSS/DCS?
Your scanner can monitor systems using a Continuous
Tone Coded Squelch System (CTCSS) and Digital Coded
Squelch (DCS) system, which allow squelch to open only
when the tone you have programmed with a specific
frequency is received along with a transmission.
CTCSS and DCS are subaudible tone signaling systems
sometimes referred to as PL or DPL (Motorola’s
trademarked terms for Private Line and Digital Private Line
respectively). CTCSS and DCS are used only for FM
signals and are usually associated with both amateur and
commercial two-way frequencies. These systems make use
of a special subaudible tone that accompanies a transmitted
signal.
CTCSS and DCS are used for many purposes. In many
cases, CTCSS and DCS are used to restrict access to a
commercial repeater, so that only those units, which
transmit the correct tone along with their signal can “talk” to
the repeater.
CTCSS and DCS are also used in areas that receive
interference where there are several stations with output
frequencies close to each other. When this occurs, you
might hear multiple communications on the same frequency.
The stations might even interfere with each other to the
point where it is impossible to clearly receive any of the

14
stations. A scanner equipped with CTCSS and DCS (like
your scanner) can code each received frequency with a
specific CTCSS or DCS frequency.
Then, when you receive multiple signals, you only hear the
transmission with the CTCSS or DCS tone you programmed.
If you do not receive the correct tone with a signal, the
scanner’s squelch remains closed and you hear nothing.
You can search for the following CTCSS frequencies and
DCS codes.
CTCSS Frequencies (Hz)
DCS Codes (Octal Code Numbers)

15
Using the Scanner at the Racetrack
Keeping up with the action at the racetrack is easy and fun.
You can hear drivers communicating with their pit crews,
officials communicating with drivers and crews, and track
workers communicating with everybody.
Each user at the racetrack transmits and receives on one or
more frequencies.
The scanner organizes racetrack frequencies by the name
of the race you are scanning and by car number.
For example, you might hear drivers and their pit crews on
the car number frequencies and officials and the news
media on the race frequencies. When you are scanning, 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.
You can activate one racing system and as many
conventional systems as you want at the same time. Within
a racing system, each driver can have multiple frequencies
stored.
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.
Today there are still many 2-way radio users who operate
using a conventional system:
• Aircraft
• Amateur radio
• LPD/PMR users
• Broadcast AM/FM/TV stations
• Many 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

16
frequently used at construction job sites, and with
inexpensive consumer radios such as LPD/PMR radios.
The range is typically 1-5 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.
Where To Get More Information
By itself, this manual really can only provide some basic
knowledge of what you need to know to have fun scanning:
just how to program and use the scanner. Do understand
more about wave propagation and radio communication,
You need more specific knowledge about RF technology or
You need to be licensed radio amateur.
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.
If you have access to the internet, you may want to visit the
following web sites for additional information:
• www.racescanner.eu - Race frequency
information, programming software and
accessories.
• http://groups.yahoo.com/group/AE230H-
A mailing list of a group for people interested in
discussing the AE230H.

Included With Your Scanner
If any of these items are missing or damaged,
immediately contact your place of purchase.
• Scanner
• PC Connection Cable
• AC Adapter
• Wrist Strap
• Belt Clip
• Batteries
• Antennas
• Owners Manual
• Headset
Setting Up Your Scanner
These guidelines will help you install and set up 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 multi-band
coverage. (You can purchase this type of antenna
at a local distributor). If the optional antenna has
no cable, use 50or 75 Ohms coaxial cable for
lead-in.
A mating BNC adapter plug might be necessary for the
optional antennas. Please use only 1 type of coaxial cable
for the connection and do never mix cables with different
impedances. If started with 50 Ohms, then stay with 50
Ohms cable in the whole installation. If the antenna cable
length should exceed about 15 meters, it is recommended
to use a low loss cable type like RG 213-U or better.
RG 58/U cable cannot be used for longer wiring.
• Use the supplied mono headset 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 Batteries
You can power your scanner using supplied rechargeable
AA batteries or other non rechargeable batteries of AA size,
which are everywhere available.
Using Rechargeable Batteries
Before you use Ni-MH (or the older Ni-Cd battery types, you
must charge them.
The scanner has a built-in circuit that lets you recharge
Ni-MH or Ni-Cd batteries while they are in the scanner. To
charge the batteries:
• Make sure the power is turned off.
• Slide the battery compartment cover.
• Install two batteries in the compartment as
indicated by the polarity symbols (+ and -) marked
inside.
• Replace the cover.
• Connect the supplied AC adapter to the scanner's
DC 6V to charge the batteries. (See “Using AC
Power” on the over next page.)

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
to REG. ALK. BATT position.
Cautions:
• Use only fresh batteries of the required size and
recommended type.
• When flashes and the scanner beeps
every 15 seconds, replace both batteries.
• 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.
WARNING!
Do not connect either adapter to the scanner if non
rechargeable batteries (such as standard or alkaline
batteries) are installed in the scanner and REG. ALK.
BATT./ NI-MH BATT. is set to NI-MH BATT (this is the
default setting with the sticker) or if you are unsure of the
switch’s position. Non-rechargeable batteries will get hot
and can even burst if you try to recharge them.
Before you use Ni-MH or Ni-Cd batteries for the first time,
charge them for 16 hours to bring them to a full charge.
Discharged batteries take about 16 hours to fully recharge.
Notes:
• Ni-MH batteries last longer and deliver more
power if you occasionally let them fully discharge.
To do this, simply use the scanner until it beeps
every 15 seconds and flashes.
• To prevent damage to Ni-MH batteries, never
charge them in an area where the temperature is
above 45°C (113°F) or below 4°C (40°F).
• If you connect an external power source to the
scanner with REG. ALK. BATT./NI-MH BATT. set
to REG. ALK. BATT., the scanner does NOT
charge the batteries. Make sure that you use the
correct batteries and set REG. ALK. BATT./
NI-MH BATT. to the correct position when you
connect an external power source.

Using AC Power
You can power the scanner using the supplied 6V, 500 mA
AC adapter. To use the scanner on AC power, plug the AC
adapter into the DC 6V socket on the side of the scanner
then plug the other end into a standard 230 V AC outlet.
If rechargeable batteries are installed without removing the
sticker, or, after removing, REG. ALK. BATT./NI-MH BATT.
is set to NI-MH BATT., the adapter powers the scanner and
recharges the installed batteries at the same time.
Connecting the Antenna
To attach the supplied stub antenna to the connector on the
top of your scanner, align the slots around the antenna's
connector with the tabs on the scanner's BNC connector.
Then slide the antenna's connector down over the scanner's
connector and rotate the antenna connector's outer ring
clockwise until it locks into place.
The smaller antenna is designed for higher frequency
ranges, While the longer antenna is optimized for the 4 m
and 2 m Band.
Connecting an Outdoor Antenna
The scanner's BNC connector makes it easy to connect a
variety of optional antennas, including an external mobile
antenna or outdoor base station antenna.
Note: Always use antenna cable of the same impedance,
for example 50-Ohm, RG-58, or RG-213 coaxial cable to
connect an outdoor antenna. If the antenna cable is over 15
meters long, use RG-213 low-loss (or better) coaxial cable.
You can get a BNC adapter suitable for Your antenna cable
from your local electronic distributor.
Connecting an Earphone/Headphone
For private listening, you can use the supplied headphone
or can plug any other 3.5 mm mini-plug earphone (not
supplied) into the headphone jack on top of your scanner.
This automatically disconnects the internal speaker.
See “Earphone Warning” at the front of the manual for
important information about using an earphone/ headphone.
Connecting an Extension Speaker
In a noisy area, an optional amplified extension speaker,
positioned in the right place, might provide more
comfortable listening. Plug the speaker cable's 3.5-mm plug
into your scanner's jack. We recommend to use a standard
external PC speaker as extension speaker, because these
speakers have exactly the amplifier needed for this purpose.
Speakers can be mono or stereo as well (in case of stereo
both speakers get the same signal).
