Cobra Electronics Corporation S120R User Manual

10mm 

Minimum

When you have found a suitable location, using 

the ’L’ shaped mounting bracket as a template, 

drill between 2 and 4 pilot holes into the selected 

mounting surface for attaching the bracket using 

either the self-tapping screws or the nuts and bolts 

provided.

You will need to attach the bracket using at least 

2 screws or 2 nuts and bolts to ensure that the 

bracket is well secured. Remember that there is a 

lot of vibration within the engine compartment 

so it is very important that the S120R mounting 

bracket is secured correctly.

When mounting and connecting the power cables 

of the S120R always ensure that you mount the 

unit and cables away from any moving parts 

such as air-cooling fans or the fan belt. Always 

position the unit so that device and power cables 

do not interfere with any moving parts within the 

engine compartment or interfer with any part 

of the vehicle that could endanger you or your 

passengers. Please check that all surfaces are safe 

to drill through before beginning any work.

The S120R has been designed to be mounted 

under the hood, behind the vehicle’s grille or 

within an air intake at the front of the vehicle if 

appropriate using the ’L’ shaped bracket and screw 

pack provided.

Find a suitable mounting position for the detector, 

ensuring that the front of the unit has a clear 

view of the road ahead and is unobstructed by 

any metallic objects and that there is a sufficient 

mounting area to attach the ’L’ shaped fixing 

bracket. The S120R needs to be mounted in as 

horizontal a position as possible so that it is looking 

directly down the road ahead.

We recommend that you mount the detector either 

behind the vehicle’s grille (if the openings of the 

grille are at least 10mm in diameter) or within an air 

intake at the front of the vehicle. The S120R can be 

mounted anywhere at the front of the vehicle, but 

for optimum performance we suggest you mount 

it as close to the number plate of the vehicle as 

possible.

The S120R is powered by wiring it directly to your 

vehicles 12v electrical system using the cable 

supplied  Firstly connect the positive side of the 

cable (Red) to a switched 12v ignition supply. 

This is a live that is On when the ignition is 

switched On and Off when the ignition is Off. 

The negative side of the lead (black) should 

be connected to a negative ground, so can be 

attached to any metal portion of the vehicles 

frame. The LED will blink red if the power 

connection has been completed successfully. This 

LED can be located near to the point where the 

power cable enters the rear of the device.
It is not advisable to connect the S120R directly
