Installing the Primary Lens

If you find that you cannot raise or lower the image enough using mechanical vertical
offset, you may need to make keystone adjustments or vertically shift the image using the
on-screen display (OSD) controls, to compensate. For detailed instructions, refer to Using
the On-Screen Menus on page 69.
If images remain keystoned or exhibit uneven brightness, the projector may simply be too
high or low in relation to the screen. Relocate the projector to correct these issues.
➤
Four or more people can lift and hand-carry the SC-1 a short distance as required.
When using a forklift to transport the SC-1, a specially-designed mounting frame with
forklift rails is required; contact Runco International for more information.
➤
Other considerations and tips that can help improve your installation:
• Keep the ambient temperature constant and below 35°C (95°F). Keep the projector
away from heating and/or air conditioning vents. Changes in temperature may cause
drifts in the projector circuitry, which may affect performance.
• Keep the projector away from devices that radiate electromagnetic energy such as
motors and transformers. Common sources of these include slide projectors,
speakers, power amplifiers and elevators.
Before or after you have positioned the projector in its permanent or temporary location,
install the remaining components: the primary lens, lamp and external extractor fan.
➤
The projection lens is shipped separately from the projector. Proceed as follows to install
the projection lens:
1. Remove the lens plug from the lens opening in the projector.
2. Place the lens cap on the projection lens to protect it from being damaged during the
installation process.
3. Remove the rear cap from the lens. This protective cap is only used during shipping to
protect the lens from damage.
4. Orient the primary lens with the serial number and UP labels at the top (see Figure 3-5).
Fully insert it straight into the lens mount opening all the way back without turning. With
the lens fully back, it will seat properly within the lens mount.
5. Lock the lens assembly in place with lens locking lever DOWN.
Caution
1. The lens seals the projection head, preventing contaminants
from entering the area of main electronics. Never attempt to
operate the projector without a lens installed. During transport
and installation, install a lens plug.
2. Always re-install a lens in its previous "UP" orientation.
