2. Initiate the mast and raise one section.
3. Remove the RCP cover to access the flags. The flags are attached to the timing rings on the
horizontal and vertical shaft gears (Figure 7-4). Each timing ring has two set screws that must
be loosened. It may be necessary to loosen one in each, then pan and tilt the unit to access
the others.
Note: The flags have sharp edges that may cause cuts.

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
position. To set the Tilt Home Position, turn the timing ring on the tilt shaft such that it rotates
down towards the upper photo sensor (see 7.6Figure 7-5). As you approach the sensor,
watch the controller. As soon as the right "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.
Repeat for the other tilt shaft.
6. To set the Pan Home Position, turn the flag counterclockwise (looking from above the RCP)
until the "Pan Right" LED goes out (see Figure 7-5). 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.
8. Stow the mast, watching for the RCP and lights to become oriented as described in the
beginning of this section. If it does not look like the RCP is properly positioned during
stowing, use the Emergency Stop to stop motion and re-adjust the flags.
