[Repeater-Builder] Kendecom Mark 4 CR Controller Audio Low

[garyp609]

I don't have documentation on the controller of this repeater. Does 
anyone know where the adjustment is to turn up the synthesized voice on 
this repeater. Any help would be greatly appreciated. If anyone has the 
hardware manual for the Mark 4 CR please let me know.
Thanks & 73's
