Maintenance Instructions

• Release the PRESET button. The horizontal axis is now calibrated.
• Calibrating Vertical Rotation - (Optional) The Vertical calibration point is factory set at 90° (straight up).
This is the position needed when wiring for extended travel (see Operating Instructions E), or when
using a Position Feedback Display. This calibration will establish the highest vertical travel point of
the monitor and allow rotation in the downward direction the total range specified during system
calibration. This differs from the horizontal rotation calibration where the zero point is in the middle of
the rotation range.
• Using the UP & DOWN controls, position the monitor such that it is aimed directly vertical or at the
uppermost limit of travel specified during system configuration.
• Press and hold PRESET and then press and release the UP button. (On the joystick, hold PRESET
and pull the stick back and release). The status LED on the monitor should blink then turn solid.
• Release the PRESET button. The vertical axis is now calibrated.
• Exit Setup Mode and check the monitor’s rotation limits. The monitor should not hit itself or other
objects. Recalibrate the EXM2 system if needed.
!
Caution: If the vertical zero point is set too far forward, the monitor may be allowed to
crash into itself at the lower points of vertical travel. BE CAREFUL NOT TO MOVE THE
MONITOR INTO OBSTRUCTIONS OR ITSELF as this will cause the monitor motors to over
current. The monitor may need to be manually reversed if this occurs.
