Scanners allow users to listen in on a number of frequencies used by professional pilots, emergency response teams and law enforcement personnel. Reporters looking for breaking news stories also use scanners. While the Realistic PRO-41 scanner is easy to operate, it requires being set up correctly to use all of its features. You can follow a few simple steps to set up a Realistic PRO-41 scanner, avoiding a trip back to the retailer for assistance.
Turn the scanner on. The PRO-41 can be powered in three ways. Either use five AA batteries, an AC adaptor for household current or a DC adaptor if using the scanner in an automobile. The adaptors and batteries are not included with the scanner. If using batteries, remove the cover from the battery compartment. Inside the compartment is a switch. Set the switch to the appropriate battery type, either "REG ALK BATT" for standard or alkaline batteries, or "NI-CAD BATT" for nickel-cadmium batteries. Insert the batteries and close the cover.
Connect the antenna. The PRO-41 uses a flexible antenna. Place the base of the antenna over the opening on the top of the scanner. Push down and twist the antenna until it locks in place. The antenna's mount is universal, designed to use a variety of other external antennas to pull in a signal.
Set the Volume and Squelch settings. Turn the volume knob clockwise and the squelch knob counterclockwise until a hissing sound is heard from the scanner's built in speaker. Slowly turn the squelch knob clockwise until the hissing stops. The squelch knob controls the amount of background noise that causes an inaudible signal. After the squelch has been adjusted, turn the volume up to a comfortable level.
Unlock the scanner. The PRO-41 has a lock button to prevent accidental loss of stored channels. Once the button is set to lock, only the volume, squelch, manual and scan buttons are operational. Unlock the scanner to program in channels. Slide the lock button to the unlocked position.
Select the frequencies to program into the scanner. The scanner's retailer sells a book with listings of the numerous frequencies available for scanning and their primary users. Online websites are also available that list these frequencies. Make a list of the frequencies to be programmed into the scanner.
Program the scanner. Press the "Manual" button to select the channel. Enter the channel number and press "Manual" again. Enter a frequency from the list created earlier. If the frequency calls for a decimal point, press "./Clear" to enter the decimal point and then the numbers that follow it. Press "Enter" to store the frequency. If an error has occurred, the scanner will display an "E" on the screen. Press "./Clear" twice to clear the screen. Repeat the programming process to enter the correct frequency.
Lock out unwanted frequencies. The scanner will continuously scan the full frequency of channels, which can be time consuming. By locking out unwanted frequencies, the scanner will concentrate on frequencies the user has programmed into the scanner. To lock out unwanted frequencies, enter the channel number. Press "Manual" followed by "Lock Out." An indicator light will turn on when the lockout is complete.
Always keep a set of fresh batteries on hand when using the scanner in the field.
