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 assigned to
function key #4 with a choice of alarm intervals of 6, 10, 12, 15 and 20 minutes. (See the
flowchart for keystroke 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-left corner of the screen
associated with a watch alarm timer counts down from the initial value (e.g., "12:00").
When a preset time interval has elapsed, an audible watch alarm is released and the screen
label WATCH turns red and the watch alarm timer freezes at "0:00."
To silence the alarm, press the AUDIO 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.
