  • Page 9: Using Ac Power, Using Vehicle Battery Power

    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.

  • Page 10: Charging Rechargeable Batteries

    • 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.

  • Page 11: Connecting An Antenna, Connecting The Supplied Antenna

    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.

  • Page 12: Connecting An Outdoor Antenna

    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.

  • Page 13: Connecting An Earphone/headphones, Listening Safely

    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.

  • Page 14: Traffic Safety, Connecting An Extension 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.
