Position of the pan/tilt sensors

There are two types of sensors in the yoke:
• A magnetic sensor with LEDs. The LED is green
if the sensor is powered and the LED is orange if
the sensor is activated by a magnet.
• An absolute encoder, which is mounted on the top
of the pan motor (pan) and on top of one of the tilt
bearings (tilt).
If any of the sensors are replaced, you must recalibrate
both the pan and tilt function. See "Calibrating the pan,
tilt and zoom function" on page 20.
