Clock Display - the scanner, in standby mode, displays the time.
The clock also features an alarm that can sound up to 20 minutes or be shut
off manually. A convenient snooze button lets you silence the alarm for an extra
5-minutes.
Delay - you can enable or disable the 2-second delay to resume scanning when
a transmission ends. Enabling this feature helps prevent missing a response from
one of the parties in the transmission.
LCD Backlight - you can enable or disable the LCD back lighted display.
Key Touch Tone - a tone sounds to confirm you have made a valid key input
while a different tone sounds to alert you to an invalid entry.
EEPROM Memory Backup - the scanner uses a non-volatile EEPROM for
memory backup.
Battery Alert - A battery icon alerts you to a no battery installed condition, and
a battery low voltage condition. An alert tone sounds when the battery needs to
be replaced. The backup provides backup for the clock when power is off and
will power scanning for a short time.
Auto Power Off - turns the scanner off when the battery power gets
too low.
