Quad-level IntelliShield

 False Signal Rejection

Highway Mode provides full immediate response to all  
signals detected.  Use this mode when you are driving on  
interstate highways.  
Automatic door openers operate in X and K-band frequencies.  To 
minimize unwanted false alerts in an urban environment where 
these sources exist, use one of the City Filtering Modes below:

• 

City X:

 automatically mutes X-band audible alert  

  until signal strength reaches level 3 or above.

• 

City X+K:

 combined with City X, automatically  

  mutes K-band audible alert until signal strength  
  reaches level 2 or above.

• 

City Plus X+K+Ka:

 combined with City X+K,  

  automatically mutes Ka-band audible alert  
  until signal strength reaches level 2 or above.

• 

City MAX:

 Maximum filtering against urban  

  false signal sources.
To choose between different City Filtering Modes vs Highway 
Mode, touch 

City/Highway Touch-point Icon

 next to the  

display and follow on-screen instructions.

IntelliMute

IntelliMute allows you to avoid audible alerts you don’t need 
to hear because you are stopped or moving slowly.  By sensing 
the RPMs of your engine, IntelliMute knows when you are at 
low speed and automatically mutes alerts.  You can set your 
preferred engine RPM activation point and/or turn on/off 
IntelliMute by following simple steps that appear on your unit 
screen, under User Settings and then IntelliMute.

•  IntelliMute Engine RPM Activation Point  
  Not Set.
•  IntelliMute On/Above Set Engine RPM  
  Activation Point.
•  IntelliMute On/Below Set Engine RPM  
  Activation Point.

Note:

 IntelliMute may not work with some vehicles, especially 

hybrids or EVs because the detector cannot sense the engine 
RPMs.  In such case, Quad-level IntelliShield City Filtering or 
Auto Mute can help reduce unwanted audible alerts.

How to Calibrate Your Compass (SLR 600 Only)

Until you calibrate the internal magnetic compass,           will 
be shown.   The compass detects the weak magnetic field of 
the Earth. It also detects magnetic fields produced by your 
vehicle, audio speakers, and other electronics. Calibration al-
lows the compass electronics to measure and store informa-
tion about all magnetic fields in your vehicle so it can ignore 
them!
To calibrate, go to the 

Menu - Users Settings

 and scroll 

right until you see the compass icon       .  Select this, and 
follow the instructions on the screen.   You will be asked to 
drive your vehicle in two complete circles. A large parking 
lot is the most convenient place to do this. Please be careful 
when making the circles and watch for other traffic. It does 
not matter what direction your vehicle is pointing when you 
start the circles, which direction you go to make the circles, 
and it does not have to be exactly two circles. You do NOT 
have to make perfect circles. It does not matter what size 
the circles are, if your speed is constant, or how fast you 
make the circles [but less than two minutes].

You will only need to calibrate the compass once.  However, if 
you move your SLR-600 to a different location in the vehicle, or 
to a different vehicle, it is best to calibration again. 

Note:

  If your compass is unable to detect the magnetic field of 

the Earth it cannot give the correct reading. This may happen if 
you are under a bridge, inside a parking garage or any building 
constructed with metal framework.  Other nearby vehicles with 
a lot of metal may also cause your compass to give inaccurate 
readings.  Your compass will work again correctly as soon as you 
get away from these. There is no need to calibrate your compass 
again after this.
