  Controls and Features

Power Button (PWR)

To turn STi MAGNUM on or off, press the 
PWR button located on the front left side. 
When you turn STi MAGNUM on, it goes 
through a sequence of alerts.
 

If you prefer, you may program your 

STi MAGNUM for a shorter power-on 
sequence. See the Programming section for 
details.

Volume

Press and hold the VOLUME•MUTE 
button, (or Mute button on the SmartPlug) 
located in the center of the front panel, 
to adjust the STi MAGNUM’s alert volume 
level. The audio will ramp up and down, 
accompanied by a bar-graph on the display. 
Once you’ve reached your preferred audio 
level, simply release the button.
 

To change the direction of the audio 

ramping (down instead of up or vice versa) 
simply release the VOLUME•MUTE button 
quickly press and hold it again to change its 
direction.

Power-on indication

After STi MAGNUM’s start-up sequence 
is complete, the alphanumeric display 
will show Highway, AutoScan, City or City 
NoX to indicate which sensitivity mode is 
selected.
        If you prefer, you can select alternate 
power-on displays. See the Programming  
section for details.

Voice Alerts

The STi MAGNUM provides digital voice  
announcements (factory default) for alerts.  
 

If you prefer, you can turn off the voice 

announcement feature and have the STi 
MAGNUM provide audible tones without 
the voice announcement. See programming 
section for details.

AutoMute

Your STi MAGNUM has our patented 
AutoMute feature. After STi MAGNUM alerts 
you to a radar encounter at the volume you 
have selected, the AutoMute feature will 
automatically reduce the volume to a lower 
level. This keeps you informed without the 
annoyance of a continuous full-volume 
alert.
 

If you prefer, you can turn the 

AutoMute feature off. See the Programming 
section for details.

Mute

The VOLUME/MUTE button, located in the 
center of the STi MAGNUM’s front panel, 
allows you to silence the audio alert during 
a radar encounter.
 

To mute the audio for a single specific 

signal, briefly press the VOLUME/MUTE
button. After that radar encounter has 
passed, the mute will automatically reset 
and the audio will alert you to the next 
encounter.

Sensitivity Button (SENS)

The “SENS” button selects the STi MAGNUM’s 
sensitivity mode. We recommend AutoScan 
mode for most driving.

Highway Mode (Highway)
In this setting, the STi MAGNUM will detect 
all signals at maximum range.

AutoScan Mode (AutoScan)
In this setting the STi MAGNUM’s internal 
computer continuously analyzes all 
incoming signals and intelligently filters 
out unwanted X and K-band false alarms 
from automatic door openers and motion 
sensors. Full sensitivity is maintained on all 
other bands.

City (City STD)
In this setting, X and K-band sensitivity is 
further reduced to eliminate unwanted 
false alarms in congested urban areas.  

City NoX (City NoX)
In this setting, K-band sensitivity is the 
same as City STD, however, X-band is 
completely turned off.

Brightness

The STi MAGNUM’s brightness is controlled 
by a sensor located behind the front display 
lens. This sensor will automatically adjust 
the display and backlit buttons based on 
the ambient light in your vehicle. If you 
prefer, you can select a fixed brightness 
level, including Full Dark Mode. See the  
programming section for details.

SmartPlug

SmartPlug is a special power  
cord that has a power-on  
indicator, a bright alert light  
that warns of radar or laser, and  
a convenient mute button right on the plug.
 

It’s the perfect addition for any vehicle 

where reaching the detector mute button 
on the windshield is a stretch. And for 
discreet night driving, put STi MAGNUM in 
the Dark Mode, and use the SmartPlug for 
your   visual alerts. Other cars won’t know 
you have a detector.

WARNING: 

Do not use the STi MAGNUM 

City NoX mode unless you are 
absolutely certain that there are no 
traffic radar guns using X-band in your 
area.
