Insert the bulb in the fresnel
.
In order to
insert the CDM bulb into the fresnel, you must open
the top lid to access the socket area inside. While
the insertion of the bulb may be easy, it is not
intuitive how to access the bulb compartment by
opening the lid. This is because the lid has a
seamless look to it and it is not evident that it can
be opened. Starting off, you should hold the lid as
shown in figure 2. This picture shows that the left
side (facing from the back or top) has hinges for
the lid and thus, the other side is a sort of latch and
is the side you will open from. To open
the lid, you should push in on the lid
firmly until it unlatches from the right
side (the side opposite of the hinges).
Then simply open it up. Inside you can
see what is known as the focusing
sled. On the focusing sled is the mirror
and the G12 socket where you will
insert the CDM bulb. Since the bulb
has an outer envelope of quartz, you
should not handle it directly with your
hands. It
’
s best to use a soft cloth of some sort as
shown in Figure 4. The oils from your fingers can
shorten the life of the bulb so keep this in mind!
There is no polarization on the bulb so therefore it is
not important which pin goes into which part of the
socket. To close the lid, simply shut it, squeeze a
bit on the lid and latch it back in place.
Put the fresnel on a stand
.
The bottom of the yoke on the
fresnel includes a yoke to baby stand adapter with a thumbscrew
adjustment to lock it in place. Open the thumbscrew enough to
allow the unobstructed insertion on the baby

adapter at the top of your stand. Then tighten the thumbscrew to
make sure of a secure attachment. The fresnel should not wobble
on the connection.
