Interpreting Alerts

Although the STi MAGNUM has a 
comprehensive warning system and this 
handbook is as complete as we can make 
it, only experience will teach you what to 
expect from your STi MAGNUM and how 
to interpret what it tells you. The specific 
type of radar being used, the type of 

transmission (continuous or instant-on) and 
the location of the radar source affect the 
radar alerts you receive.
 

The following examples will give you 

an introduction to understanding the STi 
MAGNUM’s warning system for radar, laser 
and safety alerts.

Explanation

You are approaching a continuous radar 
source aimed in your direction.  

An instant-on radar source is being used 
ahead of you and out of your view. 

An instant-on radar source or laser source is 
being used nearby. This kind of alert requires 
immediate attention!

Laser is being used in the area. Because laser 
is inherently difficult to detect, any laser alert 
may indicate a source very close by. 

A moving patrol car with continuous radar is 
overtaking you from behind. Because these 
signals are reflected (reflections are increased 
by large objects), they may or may not  
eventually melt into a solid point even when 
the patrol car is directly behind you.

Alert

The STi MAGNUM begins to sound slowly, 
then the rate of alert increases. The Signal 
Meter ramps accordingly. 

STi MAGNUM emits short alerts for a few 
seconds and then falls silent only to briefly 
alert and fall silent again.         

STi MAGNUM suddenly sounds a continuous 
tone for the appropriate band received. All 
segments in the Signal Strength Meter are lit.

A brief laser alert. 

STi MAGNUM receives weak signals. These 
signals may be a little stronger as you pass 
large, roadside objects. The signals increase in 
frequency.

Explanation

You are approaching a radar unit concealed 
by a hill or an obstructed curve.

A patrol car is traveling in front of you with a 
radar source aimed forward. Because signals 
are sometimes reflected off of large objects 
and sometimes not, the alerts may seem  
inconsistent. 

A patrol car is approaching from the other 
direction, sampling traffic with instant-on 
radar. Such alerts should be taken seriously.  

You are driving through an area populated 
with radar motion sensors (door openers, 
burglar alarms, etc.). Since these transmit-
ters are usually contained inside buildings or 
aimed toward OR away from you, they are 
typically not as strong or lasting as a real radar 
encounter.

Alert

STi MAGNUM alerts slowly for a while and 
then abruptly jumps to a strong alert.

STi MAGNUM alerts intermittently. Rate and 
strength of alerts may be consistent or vary 
wildly.         

STi MAGNUM alerts intermittently. Rate and 
strength of signal increases with each alert.         

STi MAGNUM gives an X-band or K-band alert  
intermittently.

CAUTION: 

Since the characteristics of 

these alerts may be similar to some of 
the preceding examples,  
overconfidence in an unfamiliar area 
can be dangerous. Likewise, if an alert 
in a commonly traveled area is suddenly 
stronger or on a different band than 
usual, speed radar may be set up nearby.
