Changing the Bulb on the Meridian Projector

Note

The same bulbs (SL-550) are used in both the Meridian and Cardinal Points

projectors. These are halogen cycle bulbs that have no socket assembly,

only two small wire leads. Because they are halogen bulbs, it is important

that they be handled as little as possible. Skin oil and moisture can reduce

their life expectancy. You should always clean and dry your ﬁngers before

handling the bulbs.

The bulb for the Meridian Projector is located behind a black plastic cap on the left-

hand side of the Meridian Projector. To access the bulb, use a thin bladed, athead

screwdriver to carefully pry off the cap (see photo at left). Make sure you hold the

Meridian projector rmly in one hand while removing the cap. Once the cap has

been removed, reach into the opening and carefully lift the bulb from its socket. Re-

place the bulb with one from the accessory box found in one of the small red plastic

caps attached to white foam.

When inserting the halogen bulbs in their sockets you must place the wire leads

directly in the center of the sockets that have the metal inserts. Using a small ashlight

will help you see the socket better. Push the bulb in gently until you feel resistance. Do

not push so hard that you bend the wire leads on the bulbs! Once you have replaced

a bulb, test it before putting the cap back into place. You may have to remove the

bulb and reset it in the socket if it does not light the rst time.

When you have successfully replaced the bulb, replace the cap by grasping the Me-

ridian projector rmly in one hand so it doesn’t move. Snap the cap back in place.

Changing the Bulb on the Cardinal Points Projector

Note

The same bulbs (SL-550) are used in both the Meridian and Cardinal Points

projectors. These are halogen cycle bulbs that have no socket assembly,

only two small wire leads. Because they are halogen bulbs, it is important

that they be handled as little as possible. Skin oil and moisture can reduce

their life expectancy. You should always clean and dry your ﬁngers before

handling the bulbs.

The bulb for the Cardinal Points Projector is located under the black plastic cap direct-

ly on top of the Cardinal points Projector, beneath the clear plastic projection cylinder

support plate. The easiest way to access this bulb is to rst tilt the cylinder support

plate so that the Latitude Adjustment Bar is set for the Equator. (The cylinder support

plate should be in the vertical plane.) Using a thin blade athead screwdriver, care-

fully pry off the cap (see top photo at right). Once the cap has been removed, reach

into the opening and carefully lift the bulb from its socket. Replace the bulb with one

from the accessory box found in one of the small red plastic caps attached to white

foam.

into the horizontal position.
