Only one alert symbol appears on a target at any one time. The order of
precedence is:

2. Lost Target

Although the audible
alert
may be temporarily or permanently muted
(dependent on commissioning) the visual alert symbol will always apply,
unless tracking has ceased, or the
alert
condition no longer applies.
