Manual Access — you can directly access any stored channel by entering that channel’s number. Key Lock — lets you lock the scanner’s keys to help prevent accidentally changing the scanner’s programming. Liquid-Crystal Display — makes it easy to view and change programming information.
Three Power Options — you can power the scanner from inter- nal (rechargeable or non-rechargeable batteries) or external AC or DC power (using an optional AC or DC adapter). Your PRO-79 scanner can receive these bands: Frequency Range (MHz) 29–54 10-Meter Ham Band, VHF Lo, 6-Meter Ham Band 108–136.9875...
Note: Mobile use of this scanner is unlawful or requires a permit in some areas. Check the laws in your area. SCANNING LEGALLY Your scanner covers frequencies used by many different groups including police and fire departments, ambulance services, gov-...

PREPARATION Note: If the scanner’s display locks up or does not work properly after you connect a power source, you might need to reset or ini- tialize the scanner. Important: If you have problems, first try to reset the scanner (see “Resetting the Scanner”...
Warning: Dispose of old batteries promptly and properly. Do not burn or bury them. Caution: If you do not plan to use the scanner with batteries for a month or more, remove the batteries. Batteries can leak chem- icals that can destroy electronic parts.
• You must have installed Ni-Cd rechargeable batteries in the supplied yellow rechargeable battery holder in order to charge them while they are in the scanner. If you use Ni-MH or high-capacity Ni-Cd batteries in your scanner, you must use an external charger to charge them.
You can use the supplied antenna, or you can connect an external one (not supplied). Connecting the Supplied Antenna The supplied flexible antenna helps your scanner receive strong local signals. Follow these steps to install the antenna. 1. Align the slots around the antenna’s connector with the tabs on the antenna jack.
For lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable. If the antenna cable’s connector does not fit in the scanner’s antenna jack, you might also need a PL-259-to-BNC antenna plug adapter. Your local RadioShack store carries a wide variety of coaxial antenna cable and connectors.
For private listening, you can connect an earphone or head- phones with a -inch (3.5-mm) plug to the the scanner. (Your local RadioShack store carries a wide selec- tion of earphones and headphones). Connecting an earphone or headphones automatically disconnects the internal speaker.
Doing so can create a traffic hazard and could be ille- gal in some areas. • If you use an earphone/headphones with your scanner while riding a bicycle, be very careful. Do not listen to a continu- ous transmission. Even though some earphones/head- phones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.
Once you understand a few simple terms we use in this manual and familiarize yourself with your scanner’s features, you can put the scanner to work for you. You simply determine the type of communications you want to receive, then set the scanner to scan them.

MONITOR MEMORIES The scanner has 20 monitor memories that you can use to tem- porarily store frequencies while you decide whether to save them into channels. This is handy for quickly storing an active frequency when you are searching through an entire band. You can store a frequency into a monitor memory during a service bank, or direct search.
