Attach LED assemblies to the standoff 

 

 

Dual lens/pre-amp assembly 

 

 

Attach the Airpot to the locator plate 

 
 
 
 
 
 
 
The 

LED assembly 

can now be mounted to the top of the standoff 

post by means of two 4-40 Flat Head screws.  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The 

dual lens/pre-amp assembly 

should now be carefully eased 

onto the dowel pins in the adapter block and bolted in place. It is a 
good idea to have the digital video cable already plugged onto the 
digital pre-amp circuit board before you mount this assembly. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Attach the plunger of the AirPot to the standoff on the locator 
plate. Leave the nylok screw loose enough so it will not bind the 
plunger.
