Albrecht AE80H 50-Channel Portable Scanner Owners Manual

							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.
To turn off the delay, press DLY when DELAY is displayed.
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.
TURNING THE KEY TONE ON AND OFF
Each time you press any of the scanner’s keys (except (key symbol) and LICHT), the scanner sounds a
tone.
Follow these steps to turn the scanner’s key tone off or back on.
1. If the scanner is on, turn VOLUME counterclockwise until it clicks to turn it off.
2. While you hold down the 2 and E keys, turn on the scanner.
3. After 1 second, release 2 and E.
USING THE KEYLOCK
Once you program your scanner, you can protect it from accidental program changes by turning on the
keylock feature. When the keypad is locked, the only controls that operate are LICHT, VOLUME, and
SQUELCH (and the scanner continues to scan channels). 
						

							To turn on the keylock, hold down (key symbol) for about 3 seconds until (key symbol) appears. The
scanner beeps three times (if the key tone is turned on). To turn it off, hold (key symbol) for about 3
seconds until (key symbol) disappears.
GENERAL GUIDE TO SCANNING
BIRDIE FREQUNCIES
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 RangesSpecified Interval
68-88 and 137-174 MHz5.0 kHz steps
380-512 and 806-960 MHz12.5 kHz steps
TROUBLESHOOTING
If your scanner is not working as it should, these suggestions might help you eliminate the problem. If
the scanner still does not operate properly, take it to your local store for assistance.

GENERAL RESET / INITIALIZING THE SCANNER
If the scanner’s display locks up or does not work properly after you connect a power source, you might
need to reset or initialize it.
Important: If you have problems, first try to reset the scanner. If that does not work, you can initialize the
scanner, however, initializing clears all frequencies you stored in the scanner’s memory and initialilzes
the scanner to its default settings.
Resetting the Scanner
1. Turn off the scanner, then turn it on again.
2. Insert a pointed object, such as a straightened paper clip, into the reset hole on the side of the
scanner. Then gently press and release the reset button inside the opening. The display goes blank,
then information reappears.
Initializing the Scanner
Important: This procedure clears all frequencies you stored in the scanner’s memory and initializes the
scanner to its default settings. Initialize the scanner only when you are sure the scanner is not working
properly.
1. Turn off the scanner, then turn it on again.
2. While holding down CLEAR, insert a pointed object, such as a straightened paper clip, into the reset
hole on the side of the scanner. Then gently press and release the reset button inside the opening. The
display goes blank, then information reappears.
Note: You must release the reset button before you release CLEAR. Otherwise, the memory might not
clear.
3. When the display reappears, release CLEAR.
CARE AND MAINTENANCE
The following suggestions will help you care for your scanner so you can enjoy it for years.
Keep the scanner dry. If it gets wet, wipe it dry immediately.
Use only fresh batteries of the required size and type. Always remove old and weak batteries. They can
leak chemicals that destroy electronic circuits.
Handle the scanner gently and carefully. Dropping it can damage circuit boards and cases and can
cause the scanner to work improperly. 
						

							Use and store the scanner only in normal temperature environments. Temperature extremes can
shorten the life of electronic devices, damage battereis, and distort or melt plastic parts.
Keep the scanner away from dust and dirt, which can cause premature wear of parts.
Wipe the scanner with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals,
cleaning solvents, or strong detergents to clean the scanner.
