Stake out using TILT System

Hi,
when I stake out a point using TILT System the position differs about 10 cm when I am turning around the IMMO7 Receiver. The stake out position seems to depend on the direction of the receiver. It seems, TILT does not work correctly. Ihope, I did not produced too many hidden mistaces in last half year.
Last time there was the problem with elevation and TILT.
I hope you can help dear comunity.
