This orientation photo shows the area inside the
back cover. The lamp box is at the lower left.
The fan and heat sinks, shown to the right of the
lamp box, are used to cool the instrument. No
maintenance or adjustment should be done on
these items.
If the lamp is still warm, give it several minutes to
cool. It may be hot enough to cause burns – this
should be avoided.
The lamp box contains the lamp terminals at the
upper right, and the lamp itself, held in a quick-
release holder.
There is a black arrow on the lamp, which must
be oriented to the machined groove at the top of
the lamp mounting area.
Note the three quick-release studs (one is behind
a yellow wire) which hold the lamp mounting
plate in position. In a later step, this plate will be
pushed in, then rotated to remove the lamp.
Using a #2 Phillips-head or flat-bladed
screwdriver, loosen each lamp terminal and
remove the spade lugs as shown.
Do not remove the terminal screws.
