Possible Causes and Solutions
The line and grade may have been locked. Press the STAR, then a
line or grade button to unlock. See appropriate section of the
manual.
Line or grade may have reached its furthest limit. Line limits are
indicated by the icon at the top of the display. Grade limits are
from -10% to +25% of grade.
The Target and Question Mark Icon indicates that the Alignmaster
function (Piper 200) was not able to find the target.
•
The target is missing or not positioned properly. Ensure the
reflective tapes are toward the Piper. Reposition and try again.
•
The laser beam may be blocked. Check for obstructions and try
again.
•
The target is too far from the Piper for Alignmaster to find the
target. If possible, move the target closer to the Piper and try
again.
•
The Piper may be positioned so that the target is outside the
physical limits of the Alignmaster seek area. Reposition the
Piper and try again.
