FEATURES

Your new Albrecht AE55H 50-Channel Portable Scanner gives you direct access to over 27,000 exciting frequencies, including police and fire departments, ambulance services, and amateur radio services. You can select up to 50 channels to scan, and you can change your selection at any time.

The secret to your scanner’s ability to scan so many frequencies is its custom-designed microprocessor

– a tiny, built-in computer.

Your scanner has these special features:

Ten Preprogrammed Search Bands – let you search for transmissions within preset frequency ranges, so you can find interesting frequencies more quickly.

Fifty Channels – let you store up to 50 of your favorite frequencies for easy recall and scanning.

Duplicate Frequency Check – automatically warns you if you try to store a frequency you’ve already stored, to help you use the scanner’s memory more efficiently.

Monitor Memory – lets you temporarily save a frequency located during a direct search, so you can move it to channel storage later.

Channel Lockout – keeps channels you select from being scanned.

Memory Backup – keeps the channel frequencies stored in memory for about 1 hour during a power loss.

Two-Second Scan Delay – delays scanning for 2 seconds before moving to another channel, so you can hear more replies.

Key Lock – lets you lock the keys to help prevent accidentally changing the scanner’s programming.

Flexible Antenna with BNC Connector – provides excellent reception. The BNC connector makes it easy to attach and remove the antenna or a variety of optional antennas.

Liquid Crystal Display – clearly displays how the scanner is set and makes it easy to change those settings.

Three Power Options – you can power the scanner from internal batteries (not supplied – including nonrechargeable batteries, rechargeable batteries, or a rechargeable scanner battery pack) or external AC or DC power (using optional adapters).

Your AE55H scanner can receive the following frequency bands:

26-54 MHz

68-88 MHz

137-174 MHz

380-512 MHz

For a list of the frequency ranges in the ten preprogrammed search bands, see “Search Bands”.

PREPARATION

POWER SOURCES

You can power your scanner from any of four sources:

•

. Internal batteries (not supplied) with the provided battery holder

•

. A rechargeable scanner battery pack (not supplied)

2

AE55H OWNER’S MANUAL

•

. Standard AC power (using an optional AC adapter)

•

. Vehicle battery power (using an optional DC cigarette-lighter adapter)

You can power your scanner from six AA batteries. For the longest operation and best performance, we recommend alkaline batteries. You can also power the scanner using a rechargeable scanner battery pack or rechargeable nickel-cadmium batteries, and recharge it as you use the scanner.

Caution: Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.

Notes:

•

The PWR jack lets you connect an external AC or DC adapter to operate the scanner. Connecting an adapter to PWR disconnects the internal batteries. You can use the PWR jack with either nonrechargeable or rechargeable nickel-cadmium batteries installed.

•

The CHG jack lets you connect an external AC or DC adapter to operate the scanner. The internal batteries remain connected when you connect an adapter to CHG, and get recharged when you connect a charger.

Warning: Never use the CHG jack with non-rechargeable batteries! If you try to recharge nonrechargeable batteries, they could get very hot and explode.

Battery Install

1. Press down on the battery compartment cover on the bottom of the scanner and slide the cover in the direction of the arrow to remove it.

2. Slide the battery holder out of the battery compartment.

3. If you are installing individual batteries, insert six AA batteries in the battery holder as indicated by the polarity symbols (+ and -) marked on the battery holder.

4. Slide the battery holder or battery pack into the compartment.

Caution: The battery holder or battery pack fits only one way inside the battery compartment. Do not force it.

5. Replace the cover.

When battery power is low, BATT flashes and the scanner beeps about every 3 seconds. Immediately replace all six non-rechargeable batteries or recharge the rechargeable batteries or battery pack.

Caution: Always dispose of old batteries promptly and properly. Do not bury or burn them.

Using Standard AC Power

To power the scanner from AC power, you need an AC adapter.

Cautions:

•

You must use an AC adapter that supplies 9 volts and delivers at least 200 milliamps. Its center tip must be set to negative, and its barrel plug must correctly fit the scanner’s PWR/CHG jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

•

When you finish using the AC adapter, disconnect it from the AC outlet first. Then disconnect it from the scanner.

Plug the adapter’s barrel plug into the scanner’s PWR jack. Then plug the adapter’s power module into a standard AC outlet.

3

AE55H OWNER’S MANUAL

Using Vehicle Battery Power

To power the scanner from your vehicle’s cigarette-lighter socket, you need a DC adapter.

Cautions:

•

You must use a DC adapter that supplies 9 volts and delivers at least 200 milliamps. Its center tip must be set to negative, and its plug must correctly fit the scanner’s PWR/CHG jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

•

To protect your vehicle’s electrical system, always plug the adapter into the scanner before you plug it into your vehicle’s cigarette-lighter socket. Always unplug the adapter from the vehicle’s cigarettelighter socket before you unplug it from the scanner.

Plug the adapter’s barrel plug into the scanner’s PWR jack. Then plug the adapter’s power module into your vehicle’s cigarette-lighter socket.

Charging a Rechargeable Battery Pack/Rechargeable Batteries

Your scanner has a built-in charging circuit that lets you charge a rechargeable battery pack or rechargeable nickel-cadmium batteries while it is in the scanner. To charge it, simply connect an AC or

DC adapter to the scanner’s CHG jack.

It takes about 14-16 hours to recharge a battery pack (rechargeable batteries) that is fully discharged.

You can operate the scanner while recharging the battery pack (rechargeable batteries), but charging takes longer.

Note: A rechargeable battery pack (rechargeable batteries) lasts longer if you let it fully discharge once a month. To do this, simply use the scanner until BATT flashes and the scanner beeps about every 3 seconds. Then fully charge it.

Important! At the end of a rechargeable battery pack or batteries useful life, it must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or disposal programs in your area. Some options that might be available are: municipal curb-side collection, drop-off boxes a retailers such as your local store, recycling collection centers, and mailback programs.

CONNECTING THE ANTENNA

Follow these steps to attach the supplied flexible antenna to your scanner.

1. Align the slots around the scanner’s connector with the tabs on the ANT jack.

2. Press the antenna down over the jack and turn the antenna’s base clockwise until it locks into place.

Connecting an Optional Antenna

The ANT jack on the top of the scanner makes it easy to use the scanner with a variety of antennas.

Instead of the supplied antenna, you can attach a different one, such as an external mobile antenna or outdoor base station antenna.

Follow the installation instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the ANT jack.

Warning: Use extreme caution when installing or removing an outdoor base station antenna. If the antenna starts to fall, let it go! It could contact overhead power lines, if the antenna touches a power line, contact with the antenna, mast, cable or guy wires can cause electrocution and death! Call the power company to remove the antenna. Do not attempt to do so yourself.

AE55H OWNER’S MANUAL

USING THE BELT CLIP

You can use the belt clip for hands-free carrying when you are on the go. Simply slide the belt clip over your belt or waistband.

CONNECTING AN EARPHONE/HEADPHONES

For private listening, you can plug an earphone or mono headphones with a 3.5 mm plug into the

PHONE jack on top of your scanner. This disconnects the internal speaker.

Caution: To protect your hearing, follow these guidelines when you use an earphone or headphones:

•

Do not listen at extremely high volume levels. Extended high-volume listening can lead to permanent hearing loss.

•

Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.

Warning: Do not use an earphone or headphones with your scanner when operating a motor vehicle or riding a bicycle, in or near traffic. Doing so can create a traffic hazard and could be illegal in some areas.

CONNECTING AN EXTENSION SPEAKER

In a noisy area, an extension speaker or an amplified speaker might provide more comfortable listening.

Plug the speaker cable’s 3.5 mm plug into your scanner’s PHONE jack.

AE55H OWNER’S MANUAL

You can search these bands to quickly find active frequencies you might want to store into the scanner’s channels. For example, if you wanted to search for transmissions between amateur radio operators, you could search only the search bands where you are most likely to hear the transmissions

(Bands 5, and 8).

Note: The frequencies in the scanner’s search bands are preset. You cannot change them.

Monitor Memory

The scanner also has a monitor memory that you can use to temporarily store a frequency while you decide whether to save it into a channel. This is handy for quickly storing an active frequency when you are searching through an entire band using direct search. See “Direct Search”.

OPERATION

TURNING ON THE SCANNER/SETTING VOLUME AND SQUELCH

Note: Make sure the scanner’s antenna is connected before you turn it on.

1. Turn SQUELCH fully counterclockwise.

2. Turn VOLUME clockwise until it clicks and you hear a hissing sound.

3. Turn SQUELCH clockwise until the hissing sound stops.

Notes:

. If the scanner picks up unwanted, partial, or very weak transmissions, turn SQUELCH clockwise to decrease the scanner’s sensitivity to these signals. If you want to listen to a weak or distant station, turn

SQUELCH counterclockwise.

. If SQUELCH is adjusted so you always hear a hissing sound, the scanner does not scan properly.

. If you have not stored frequencies into any channels, the scanner does not scan.

STORING ACTIVE FREQUENCIES

You can manually store frequencies you already know into the scanner’s channels. You can also store frequencies you found using band search directly into channels. You can also store a frequency into a monitor memory then store it into a channel.

If you do not have a reference to frequencies in your area, follow the steps in “Band Search” or “Direct

Search” to search for transmissions.

Manually Storing Frequencies

If you know a frequency you want to store, you can store it manually.

1. Press PGM. PGM appears.

2. Use the number keys to enter the channel number where you want to store the frequency (1-50), then press PGM again. Or, repeatedly press PGM until the desired channel number appears.

3. Use the number keys and DLY/. to enter the frequency (including the decimal point) you want to store into that channel.

4. Press E to store the frequency.

Notes:

•

If you entered an invalid frequency in Step 3, Error appears, the channel number flashes, and the scanner beeps three times after you press E. Simply repeat Steps 3 and 4.

7

AE55H OWNER’S MANUAL

•

Your scanner automatically rounds the entered frequency down to the nearest valid frequency. For example, if you enter a frequency of 151.4730, your scanner accepts it as 151.4700.

•

. If you entered a frequency that is already stored in another channel, dUPL (duplicate) and the lowest-numbered channel containing the duplicate frequency flash for about 3 seconds. To store the frequency anyway, press E again.

5. Repeat Steps 2-4 to store more frequencies into channels.

Band Search

If you do not know of a frequency to store, you can search your scanner’s preprogrammed search bands (see “Search Bands”) for active frequencies, then store any that you find into your scanner’s channels.

Follow these steps to search for and store active frequencies using band search.

1. Press BAND. The last selected band number (B followed by the band number) and the frequency search range appear for about 2 seconds.

2. To select a different band within 2 seconds, enter the band’s number (0-9) or repeatedly press BAND until the desired band number appears.

After about 2 seconds, SRCH Up appears, the next available channel flashes, and the scanner begins searching rapidly upward in that band (from lowest to highest frequency) for an active frequency.

Notes:

. To reverse the search direction at any time, hold down the Down key for about 1 second.

. To search the band upward or downward in small increments (in steps or 5 of 12.5 kHz, depending on the band), repeatedly press and release Up or Down.

The scanner stops when it finds an active frequency.

3. To store the displayed frequency in the channel currently flashing on the display, press E. The scanner stores the frequency, then the next available channel flashes and continue the search.

Notes:

. After you store a frequency into the last available channel, --ch appears instead of a channel number.

If you try to store a channel while --ch appears, Ch FULL appears briefly. In order to store more frequencies, you must clear some channels. See “Clearing a Channel”.

Direct Search

You can search up or down from the currently displayed frequency and store the frequency into the monitor memory.

1. Press MANUAL or PGM, then use the number keys and DLY/. to enter the frequency where you want to start the search.

Note: To start from a frequency already stored in one of your scanner’s channels, press MANUAL or

PGM, enter the desired channel number, then press MANUAL or PGM again.

2. Hold down Up or Down for about 1 second to search up or down from the selected frequency.

When the scanner finds an active frequency, it stops searching.

3. To store the frequency in the monitor memory, simply press MON. MON appears on the display.

4. To continue the search, hold down Up or Down for about 1 second.

SPECIAL FEATURES

DELAY

Many agencies use a two-way radio system that might have a pause of several seconds between a query and a reply. To avoid missing a reply, you can program a 2-seocnd delay into any of your scanner’s channels. Then, when the scanner stops on the channel, DELAY appears and the scanner continues to monitor the channel for 2 seconds after the transmission stops before it resumes scanning.

You can program a 2-second delay in any of these ways:

. If the scanner is scanning and stops on an active channel, quickly press DLY before it starts to scan again.

. If the desired channel is not selected, manually select the channel then press DLY.

. If the scanner is searching, press DLY during the search.

DELAY appears and the scanner automatically adds a 2-second delay to every transmission it stops on.

LOCKING OUT A CHANNEL

You can scan existing channels faster by locking out a channel that has a continuous transmission.

To lock out a channel, select the channel then press L-OUT. L/O appears.

To remove the lockout from a channel, manually select the channel then press L-OUT until L/O disappears.

Notes:

. You can still manually select locked-out channels.

. Your scanner automatically locks out empty channels.

USING THE DISPLAY BACKLIGHT

You can turn on the display’s backlight for easy viewing in dimly-lit areas. Press LICHT to turn on the display light for 5 seconds. To turn off the light before it automatically turns off, press LICHT again.

AE55H OWNER’S MANUAL

GENERAL GUIDE TO SCANNING

BIRDIE FREQUENCIES

Every scanner has birdie frequencies. Birdies are signals created inside the scanner’s receiver. These operating frequencies might interfere with broadcasts on the same frequencies. If you program one of these frequencies, you hear only noise on that frequency. If the interference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie.

To find the birdies in your scanner, being by disconnecting the antenna and moving it away from the scanner. Make sure that no other nearby radio or TV sets are turned on near the scanner. Use the search function and scan every frequency range from its lowest frequency to the highest. Occasionally, the searching will stop as if it had found a signal, often without any sound. That is a birdie. Make a list of all the birdies in your scanner for future reference.

SPECIFIED INTERVALS

Frequencies in different bands are accessible only at specific intervals. For example:

Frequency Ranges

26-54, 68-88, 137-144 and 146-174 MHz

144-146 and 380-512 MHz
