4. Once the set screws are loose, pan and tilt the unit to the correct home position. Be careful
that the flags do not come into contact when panning and tilting, or they may be bent.
5. The pan and tilt functions have two photo sensors for each function. It is important that the
flags engage the correct photo sensor from the proper direction when setting the home posi-
tion (Figure 7-4). To set the Tilt Home Position, turn the timing ring on the tilt shaft such that it
rotates counterclockwise toward the photo sensor (see Figure 7-4). As you approach the sen-
sor, watch the controller. As soon as the "Tilt Down" LED goes out, stop rotating the ring and
tighten the set screw. This should be roughly 80% penetration into the sensor with the flag.
6. To set the Pan Home Position, turn the flag clockwise (looking from above the RCP) until the
"Pan Right" LED goes out (see Figure 7-4). Tighten the adjustment screws to secure the ring.
7. Tilt the unit until the second set screw for the tilt flag is accessible. Tighten the second set
screw.
