Flexible Antenna with BNC Connector — provides ex- cellent reception and is designed to help prevent anten- na breakage. Or, you can connect an external antenna.

Memory Backup — keeps the frequencies stored in memory for an extended time.

Three Power Options — let you power the scanner us- ing the built-in rechargeable battery pack, external AC power using the supplied AC adapter/charger, or DC power using an optional DC cigarette-lighter power ca- ble.

Key Confirmation Tones — the scanner sounds a tone when you perform an operation correctly, and an error tone if you make an error.

Battery Low Alert — warns you when battery power gets low.

Battery Save — saves battery power when the scanner does not detect any transmissions for more than 1 minute when a channel is manually selected.
