The module is supplied with Generic Instructions, a fused DC power lead, fitting kit and specific fitting guides for the Kenwood SP31 and Yaesu SP8. Other installation guides for the following speakers:

The module is inserted into the target circuit in line with the loudspeaker. The power connector is prewired, and corresponding fused power lead is supplied. The control keyboard is mounted in a convenient location, and finished with a supplied matt black profession label.

"Best cop I have had on 40 MTRS" 
James M Madigan Sr, Chicago

"The module comes with excellent fitting instructions and the on-air performance in improving readability of weak SSB signals or those in noisy conditions was excellent. I already use a bhi
unit (how's that for a recommendation!), but if I hadn't already got one this would not have been returned to the supplier - instead I would have bought it for use in my station."
