Saturation
Note the following about adjusted saturation:
• The saturation can be adjusted independently for each color (R,G,B,C,M, and Y).
• A saturation level of 0 removes all color from that region.
• A saturation level of 254 sets the color region to have maximum color.
• A saturation level of 127 does not change the saturation.
Gain
Note the following about adjusted gain: • The gain can be adjusted independently for each color (R,G,B,C,M,Y, and W).
• The range of input is 0 to 254.
• The gain changes the intensity level of the respective color.
• A gain level of 127 disables the HSG controls for that color.
• A gain level less than 127 darkens the respective color.
• A gain level of 254 sets the color region to have maximum gain; however, clipping occurs on the signal.
• A gain of 127 is the nominal setting.
• White provides three gain level controls, one each for the R,G,B component of white.

Light Source menu
The Light Source menu sets the light source mode and power preferences.
Menu itemDescriptionOptions
Light Source 
Mode Sets the light source mode.
• Constant Power
• Constant Intensity
• ECO 1/ECO 2
• Rental Mode—Adjusts to the lowest fan  speeds and switches  the laser diode power 
to the minimum setting.
Constant Power Sets the value of the laser diode power. —
Constant 
Intensity Sets the value for the Constant Intensity 
mode to maintain constant brightness.
The light sensor monitors the light level and 
consumes more power as
 the laser brightness 
decays naturally over time. When the laser 
setting reaches the maximum power, it 
remains at this setting.
Note the following:
• Light sensor must be calibrated for  Constant Intensity mode to work properly. 
The calibration must be  performed after the 
laser diode replacement.
• Constant Intensity mode  is disabled if Light 
Sensor Calibration is not completed.
• Constant Power mode and Constant  Intensity mode conflict with each other. 
When one function is  enabled, the other 
function is automatically disabled.
• When Constant Intens ity mode is enabled, 
the Dymanic Black and RealBlack functions 
are automatically disabled. —
Light Source 
Info Displays information about the light source in 
the projector. • Total Projector Hours—Displays the current 
total number of hours the projector has been 
used.
• LD Hours—Displays the current total number  of hours the laser diode has been used.
Light Sensor Calibrates the light sensor. —
