When pairing new device, ensure module has not already connected to or is 
within range of another paired device. Module is ready for pairing when LED 
flashes green. See LED status through peep-hole on module underside

 

9.

 

Do I need options noise filter?

 

More than 95% of our installs required the filter and because of that 

we highly recommend you add it. 

Adding extra accessories to the 

electrical circuit in older vehicles may result in alternator noise (whine). 
The optional noise filter (See 

Fig. 10

) helps eliminate these annoyances. If 

you purchase filter along with module, we will wire it up; however if you opt 
out, one can be purchase

 

here

 

as a DIY.
