clamp screw is tightened. For all other lamp types, keep the "flat" part of the anode
end of the lamp facing up.
f. Tighten screws in both negative and positive lamp connectors. Important! Proper electrical contact
prevents resistance in the lamp connectors. CAUTIONS! 1) Handle the lamp by the cathode/
anode end shafts only, never the glass. DO NOT over-tighten. DO NOT stress the glass
in any way. 2) Check leads. Make sure the anode (+) lead between the lamp and igniter
is well away from any projector metal such as the reflector or firewall.
g. Re-install the front lamp duct.
CRITICAL! As you install the front lamp duct, lift the small light
shield on the rear lamp duct cover so that it does not get jammed
between the two pieces when they come together. (Figure 5-45)
To ensure a good fit between the two pieces, squeeze the top and
bottom cover snaps to ensure they are locked in place. The light
shield should move freely to the touch.
4. Close lamp door.
5. Turn wall circuit ON.
6. Perform software adjustments. In the Advanced Setup: Lamp
History window, tap the Add Lamp button and record lamp type,
serial number, reason for change and number of the hours logged
on to the lamp. If the lamp has not been previously used, enter 0.
Press Save to save the data entered (Figure 5-46).
