'EMERGENCY' every 2 seconds.
TIMESTAMP – This is the time of day that the last ANI
was received. The timestamp is in 24-hour format. In
24-hour format, 4 A.M. is displayed as 04:00 and 4
P.M. is displayed as 16:00. Note that the timestamp
changes only when a new ANI comes in, it is not a
time-of-day clock.

other ANI’s previously logged. Press the left

to indicate that an emergency ANI was received
recently. This indicator remains blinking until the
operator presses any key.
TRANSMIT / BUSY LED – This LED is off when there
is no activity. It glows red during transmit. It blinks
green any time the radio channel is busy (provided the
COR input is connected).
