Table 9 lists the binary coding of the system status (for bytes 22 and 23 from table 8):
The error 0x0002 can also occur during a normal transponder crossing if the code
transmission is aborted by decreasing level. It has no meaning if there is no tran
-
sponder in the field.

ESTIMATE_Y
Crosswise to the direction of travel:
If the exact transponder position cannot be determined due to incor

rect reading distances or e.g. reinforcements in the ground, then an
estimated value with the accuracy of ±10 mm is determined and this
bit is set.

ESTIMATE_X
In direction of travel:
If the exact transponder position cannot be determined due to incor
