AE75H OWNER’S MANUAL OWNER’S MANUAL AE75H 50-Channel Portable Scanner 1
AE75H OWNER’S MANUAL FEATURES Your new Albrecht AE75H 50-Channel Portable Scanner gives you direct access to over 22,000 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.
AE75H OWNER’S MANUAL 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) • 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.
AE75H OWNER’S MANUAL • 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. Using Vehicle Battery Power To power the scanner from your vehicle’s cigarette-lighter socket, you need a DC adapter.
AE75H OWNER’S MANUAL 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.
AE75H OWNER’S MANUAL CLEAR – clears an incorrect entry. PGM – lets you program frequencies into channels. Number Keys – use these keys to enter the numbers for a channel or frequency. DLY/. (delay/decimal point) – programs a 2-second delay for the selected channel, or enters a decimal point (necessary when programming frequencies). L-OUT/E (lockout/enter) – locks out channels so they will not be scanned, or enters frequencies into channels.
AE75H OWNER’S MANUAL 6 7 8 9 410-430 430-440 440-450 450-470 UHF 70-cm Amateur Radio UHF UHF 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 4, and 7). Note: The frequencies in the scanner’s search bands are preset. You cannot change them.
AE75H OWNER’S MANUAL 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. • • 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.

AE75H OWNER’S 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.
AE75H 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.
