Instant-On Detection
Your detector is designed to detect
Instant-On
speed monitoring signals,
which can suddenly appear at full strength.
NOTE
You should take appropriate action immediately whenever
an instant-On alert is given.
Pop Detection
Your detector is designed to detect single pulse mode radars. These radars
are designed to have a low probability of detection. You should note that
these radar guns have a much shorter range while in this mode.
