Albrecht AE55H Portable Scanner Short Form Manuals

							1. Press MANUAL.
2. Enter the channel number.
3. Press MANUAL again.
SCANNING THE CHANNELS
To begin scanning channels or to start scanning again after
monitoring a specific channel, press SCAN.
SCAN and Up-symbol appear, and the scanner begins to
rapidly scan upward until it finds an active frequency.
If the scanner finds an active frequency, it stops and displays
that channel and frequency number, then it automatically
begins scanning again when the transmission ends on that fre-
quency.
Notes:
. You must store frequencies into channels before the scanner
can scan them.
. To change the scanning direction, press Up or Down.
. The scanner does not scan empty channels.
LISTENING TO THE MONITOR MEMORY
To listen to the frequency stored in the monitor memory, press
MANUAL then MON. MAN, MON and the frequency stored in
the monitor memory appear.
CLEARING A CHANNEL
1. Press MANUAL.
2. Use the number keys to enter the channel number contai-
ning the frequency you want to delete, then press PGM. Or,
repeatedly press PGM until the desired channel number appe-
ars. PGM appears.
3. Press CLEAR. The frequency number flashes.
4. Press L-OUT. L/O (lockout – see “Locking Out a Channel”)
appears, the channel number flashes, and the frequency num-
ber changes to 000.0000 to indicate the frequency is cleared.
5. To delete more frequencies, repeat Steps 2-4. 
						

							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.
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 acci-
dental 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 FREQUENCIES
Every scanner has birdie frequencies. Birdies are signals crea-
ted 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 scan-
ner. 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 RangeSpecified Interval
26-54, 68-88, 137-144 and 146-174 MHz 5.0 kHz steps
144-146 and 380-512 MHz 12.5 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.

RESETITNG/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 reappe-
ars. 
						

							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 environ-
ments. Temperature extremes can shorten the life of electronic
devices, damage batteries, 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.
