1.33.3 Watch alarm
The watch alarm sounds an external buzzer at selected time intervals to help you keep
regular watch of the radar picture for safety or other purposes. This feature can be as-
signed to function key #4 with a choice of alarm intervals of 6, 10, 12, 15 and 20 minutes.
(See the flowchart on page 1-45 for sequence.)
Provided that function key #4 is assigned the watch alarm feature, just press function key
#4 to activate the feature. The label WATCH appears at the lower-right corner of the screen
associated with a watch alarm timer counts down from the initial value (for example, “12:00”).
When a preset time interval has elapsed, an audible watch alarm is released and the label
WATCH turns red and the watch alarm timer freezes at “0:00.”
To silence the alarm, press the [AUDIO OFF] key. The label WATCH turns to normal color
and the watch alarm timer is reset to the initial value and starts the count-down sequence
again.
If you press the [AUDIO OFF] key before the selected time interval is reached, the watch
alarm timer is reset to the initial value and starts the count-down sequence again.
