Flexible Antenna with BNC Connector — provides
excellent reception and is designed to help prevent an-
tenna breakage. Or, you can connect an external an-
tenna.
Monitor Memories — let you temporarily store up to 5
frequencies or IDs.
Memory Backup — keeps the frequencies stored in
memory for an extended time if the PRO-91 loses pow-
er.
Three Power Options — let you power the scanner
using internal batteries, external AC power using an
optional AC adapter/charger, or DC power using an op-
tional DC cigarette-lighter power cable.
Key Confirmation Tones — the scanner sounds a
tone when you perform an operation correctly, and an
error tone if you make an error.
Battery Save — saves battery power when the scan-
ner does not detect any transmissions for more than 5
seconds when a channel is manually selected.
Battery Low Alert — warns you when battery power
gets low.
