Power Connection

To apply power to the STi MAGNUM, plug 
the small end of the power cord, 
(telephone type connector) into the 
modular jack on the STi MAGNUM’s right 
side, and plug the lighter plug adapter into 
your vehicle’s lighter socket or accessory 
socket.

Your STi MAGNUM operates on 12 volts DC 
negative ground only. The lighter plug 
provided is a standard size and will work in 
most vehicles. However, some vehicles may 
require the optional European sleeve to 
ensure a snug fit. If so, simply call our 
service department and we’ll send you one. 
This sleeve slides over the power cord’s 
lighter plug adapter. Of course, your lighter 
socket must be clean and properly 
connected for proper operation.

Mounting Location

Where to mount STi MAGNUM

For optimum detection performance, we 
recommend the following:

• Using the Windshield QuickMount, 
mount your STi MAGNUM level, and 
high enough on your front windshield to 
provide a clear view of the road from the 
front and rear.

• Mount the STi MAGNUM away from 
windshield wipers, other solid objects, and 
heavily tinted areas that might obstruct the 
radar antenna or laser lens.

  Installation

Windshield QuickMount

The STi MAGNUM’s QuickMount wind-
shield bracket is designed for unobtrusive 
and hassle-free mounting and removal. 

1

  Depress the adjustment button on 

the top of the STi MAGNUM (by the word 
BELTRONICS) and slide the QuickMount 
bracket into the slot until it is locked into 
the position which best fits the angle of 
your windshield (there are four settings 
available). For extremely horizontal 
or extremely sloped windshields, the 
QuickMount bracket can be bent.

To ensure that the suction cups  
adhere to the windshield firmly,  
be sure to keep both your windshield and 
the suction cups clean.

2

  To adjust the STi MAGNUM on your 

windshield, use the QuickMount  
adjustment button located on the top 
of the STi MAGNUM, and slide the STi 
MAGNUM forward or backward to obtain a 
level position.

User’s Tip

You can leave the QuickMount bracket 
in place on your windshield, and easily 
remove STi MAGNUM by pressing the  
adjustment button and sliding the STi 
MAGNUM off the mount. Again, be sure to 
position the bracket where it won’t present 
a hazard in the event of an accident. 
Additional mounts are available for other 
vehicles in your household.

N0TE: 

Depending on your vehicle, the 

lighter socket power may either be  
continuously on, or it may be switched 
on and off with your ignition switch. We 
suggest using a direct-wire SmartPlug 
connected to a switched circuit at the 
fuse box if the lighter socket is  
continuously on.

CAUTION: 

A few vehicles (including some 

Porsches) have windshields with a soft 
anti-lacerative coating on the inside 
surface. Use of suction cups will  
permanently mar this coating. Consult 
your dealership or the vehicle owner’s 
manual to determine if your windshield 
has this coating.

WARNING:

 BELTRONICS cannot  

anticipate the many ways STi MAGNUM 
can be mounted. It is important that you 
mount STi MAGNUM where it will not 
impair your view nor present a hazard 
in case of an accident.

NOTE: 

When installed and adjusted  

properly, the back top edge of the STi 
MAGNUM should rest solidly against 
your windshield.
