Detection
Your Detector
Signals Detected
The tables on the following pages show you the types of Signals your detector will
detect, as well as the visual alerts it provides for each of them.
Audio Alerts
A distinctly different Alert tone is used for each type of signal detected (including
separate tones for each laser signal). For X, K and Ka band radar signals, the tones
will repeat faster as you approach the signal source. The repeat rate of the tones
gives you useful information about the signal detected. (See responding to alerts
on page 14.)
Visual Display
An indication of the type of signal
detected and, for radar signals, the
signal strength will appear in the
Easy-to-Read Display. Radar signal
strength will be indicated by steady,
ashing, or a combination of steady
and ashing LEDs as shown in the
signal strength chart below.
