To prevent damage to Ni-MH batteries, never charge them in an area where the temperature is above 45°C (113°F) or below 4°C (40°F).

If you connect an external power source to the scanner with REG. ALK. BATT./NI-MH BATT. set to REG. ALK. BATT., the scanner does NOT charge the batteries. Make sure that you use the correct batteries and set REG. ALK. BATT./ NI-MH BATT. to the correct position when you connect an external power source.

Using AC Power

You can power the scanner using the supplied 6V, 500 mA AC adapter.

To use the scanner on AC power, plug the AC adapter into DC 6V on the side of the scanner then plug the other end into a standard AC outlet.

If rechargeable batteries are installed without removing the sticker, or, after removing, REG. ALK. BATT./NI-MH BATT. is set to NI-MH BATT., the adapter powers the scanner and recharges the installed batteries at the same time.

Connecting the Antenna

To attach the supplied stub antenna to the connector on the top of your scanner, align the slots around the antenna's connector with the tabs on the scanner's BNC connector. Then slide the antenna's connector down over the scanner's connector and rotate the antenna connector's outer ring clockwise until it locks into place.

Connecting an Optional Antenna

The scanner's BNC connector makes it easy to connect a variety of optional antennas, including an external mobile antenna or outdoor base station antenna.

Note: Always use 50-ohm, RG-58, or RG-8, coaxial cable to connect an outdoor antenna. If the antenna is over 50 feet from the scanner, use RG-8 low-loss dielectric coaxial cable. You can get a BNC adapter at your local electronics store.
