9.1.3 CONTRAST
The contrast of an image is defined as the relation between dark and light
colors. An image of high contrast is often regarded as ' hard' , as compared
to the ' soft' feeling of a low contrast image. Low contrast is recommended
for long term viewing, while high contrast is used to enhance details. Use
the CONTR keys on the remote control (RC) to adjust the contrast. Also
see Brightness. The contrast setting is stored individually for each mode.
9.1.4 BRIGHTNESS
The brightness is the amount of white in an image. The brightness is
adjusted to the ambient lighting conditions. Usually, a bright, low contrast
image is preferred. Use the BRIGHT keys to adjust brightness. See also
Contrast. The brightness setting is stored individually for each source.
9.1.5 TUNE
This feature enables a stable image. An unstable image can be seen as
sideways instability or " swimming" . Press TUNE until a stable image is
achieved. The setting is stored individually for each source. Observe that
TUNE only works provided the FREQUENCY setting is correct.
9.1.6 ON/OFF
This switch controls the operation of the projector. When switched on, all
functions are active. When switched off, the fan is still operating, but the
image is turned off. If the unit is left off for more than 5 minutes, the lamp
is also turned off and after another 2 minutes the fan terminates. The
ON/OFF switch is a toggle key.
After the lamp is turned off, the unit can only be turned on
again after a safety delay of 60 seconds. If the projector is
turned on during the safety delay period, the On/Off indicator
will blink slowly until the 60 seconds have passed and the lamp
is turned on.
9.1.7 RESET
This feature enables standard settings of most controls. RESET will only
reset the active mode.
A fundamental master reset may be performed by pressing all
four top panel keys simultaneously. All settings will return to
factory defaults, so do not perform a master reset unless it is
really required. This operation will also erase all custom
sources and modes that have been memorized.
