5.0 TROUBLESHOOTING
Fuses are located inside the left cover of the pan/tilt unit. Fuses F1 (mother board)
and F2 (camera) are 2/10-ampere, slow-blow fuses. F3 (pan/tilt) is a 1-ampere,
slow-blow fuse. To order fuses F1 and F2, specify the part number FUS2/10SB. To
order fuse F3, specify the part number FUS1SB.
If you need to return the pan/tilt system and you can not place the camera enclo-
sure in a horizontal position, remove three of the four Allen bolts that attach the
enclosure to the tilt shaft. This will allow movement without damage to the gear
train assembly components.
Figures 6-7 and Tables A-B show exploded assembly diagrams and parts lists for
the blower and heaters, if your model is equipped with them.
Figures 8-10 show the wiring, component locations, and layout of traces for the
circuit board in the enclosure.
