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.

designed to have a low probability of detection. You should note that these radar
guns have a much shorter range while in this mode.
