I acquired a Precision E-310 Sine & Square generator a while back and have been trying to locate a copy of the manual. If anyone has one, I would gladly pay copying and postage cost. Want to use it to align several of my boatanchors. Thanks David Nance WB4SSE 3555 Grandin Road SW Roanoke, VA 24018 e-mail: dmnance at roanoke.infi.net
