Using the Mute Feature
Press the MUTE button to switch between “START MUTE” and “END MUTE”. In the “END MUTE”
mode, the radar detector automatically lowers the audio alert level to the ambient noise
level in your vehicle when it detects a continuous signal for 5 seconds or more. The audio
alert level remains low for 60 seconds, even if, during that time, a second separate signal is
detected. In the “START MUTE” mode, the radar detector will remain completely silent but
will continue to provide visual alerts.
Understanding Signal Alerts
Three radar bands (X, K, and superwide KA) and one laser band are typically used by police
radar/laser devices. When a radar signal is detected, the screen displays the name of the
radar band – “X”, “K”, or “KA” – together with a number indicating the strength of the
detected signal (called the signal strength meter).
• There are 8 levels in the signal strength meter – 1 to 8. The higher the number, the
stronger the signal.
• The signal strength meter can provide a good indication of the proximity of the
detected signal. Usually, strong signals are closer to you than weak signals.
When a laser signal is detected, the screen displays “LASER”.
For more information about dierent kinds of radar and laser devices and detectors, see the
ABOUT RADAR / LASER DETECTION section, page 6.
Using the Alert Filter Button
Press the ALERT FILTER button to switch between lter modes. The factory default is FILTER-
NORMAL.
• FILTER-NORMAL – Optimized ltering for typical city or highway driving. The NORMAL
mode reduces all X band and other known radar signals commonly associated with
annoying false alerts in city and suburban areas. When this mode is selected, the screen
will scroll “FILTER-NORMAL MODE”.
• FILTER-HIGH – Increased ltering to reduce most false alerts, good for high-density
commercial areas. The HIGH mode is ideal when you’re receiving frequent false alerts.
Most North American speed monitoring systems use the K or KA bands, and this mode
will not adversely aect the sensitivity to police radar/laser devices. The HIGH mode
lters out all X band radar signals. X band radar is not detected in the HIGH mode. When
this mode is selected, the screen will scroll “FILTER-HIGH MODE”.
• FILTER-OFF – No ltering of alert signals, ideal for open space areas. The OFF mode
eliminates the X band lter and is recommended for driving in areas where X band
radar devices are still in use. While now being phased out in most areas, X band is still
used in some locations. When this mode is selected, the screen will scroll “FILTER-OFF
MODE”.
X band, occupied by police radar, is also used for other devices, such as automatic door openers like
those at supermarkets, burglar alarms, terrestrial microwave emission, and more. In addition, other
radar detectors in close proximity may falsely alert your detector. Filtering false alerts will help you
travel more comfortably.
