Handheld Programmer 

The handheld programmer can be used to adjust all 
of the parameters that the TCP software does, but is 
a simple, self contained system that does not require 
a computer.  Most users prefer the handheld.  The 
handheld programmer is available as a hard wired 
unit, or a wireless Bluetooth

 connected unit.
