Slide Trays:

KODAKEKTAPRO80SlideTrayforhold- ing 80 slides with a maximum slide mount thickness of 3.2 mm.

KODAK CAROUSEL TRANSVUE 140 Slide Tray for holding 140 slides with a maximum slide mount thickness of 1.2 mm.

SlideGate:

Gravity-feed slide change with register- gate pressure levers in two planes to ensure good slide alignment.

LensMount:

Universal lens mount for both spiral- and rack-mounted lenses (such as KODAK Projection FF Lenses).

Height Setting:

Height setting to a maximum of 10o via two turnable feet.

Levelling:

The projector may be operated at an angle of plus or minus 30o from the horizontal along the projector axis.

Note: Tilting the projector side ways will adversely affect the lamp lifetime!

Housing:

Sturdy,fibre-glassreinforcedhousing (LEX- AN).

All parts are marked and therefore fully recyclable.

All important structural elements for the optical equipment such as slide gate, lamp module and base for the lens mount hous- ing are in die-cast zinc assemblies.

ProjectionLamps (available as accessories): EXR82V/35h/300W Brightness 100%

FHS82V/70h300W Brightness 80% EXY82V/200h250W Brightness 60%

The economy setting reduces the lamp output to around 75% of the normal value (tripling bulb life).

The high light setting increases the lamp output by 20% (whilst reducing bulb life by 30%).

Temperature range for safe operation The operating temperature range of the projector depends on the ambient temper- ature and the voltage (see illustration). Standard and economy setting: Minimum0o Candmaximum+40o C High Light setting (models 7020/9020): Minimum0o Candmaximum+35o C

Should the projector overheat, e.g., due to lack of cooling air, the built-in thermal cut- out automatically switches the lamp off and then switches it on again once it has cooled down.
