LCD PANEL
• The LCD panel’s liquid contains an irritant. If the panel is damaged and the liquid con
-
tacts your skin, rinse immediately the contact area with running water for at least 15
minutes. If the liquid gets in your eyes, rinse immediately your eyes with running water
for at least 15 minutes and consult a doctor.
• The following phenomena are LCD characteristics, and NOT a product defect:
- LCD screen may show uneven brightness depending upon displayed images or con
-
trast settings.
- The LCD screen pixels may contain minute black-and-white-colored spots.
- The color displayed on the LCD screen may appear different when seen from outside
the specified viewing angle.
- When the same image is displayed on the screen for a long time period, an afterim
-
age may appear when the image is changed. If this happens, turn off the 73VR1100
and wait 10 seconds before restarting it.
• To prevent an afterimage:
- Set the screensaver when you plan to display the same image for a long time pe-
riod.
- Plan to change the screen image periodically so that the same image does not remain
for the long time period.
■
BACKLIGHT
• Even when the backlight is failed, the screen display can be controlled by touching it.
• Backlight failure is confirmed by the following phenomena:
- The screen gets dark even when no screensaver setting is enabled.
- If the screensaver is activated, the screen display does not recover when the screen
is touched.
• The backlight can be replaced in M-System factory. The LCD must be replaced at the
same time. Please consult M-System.
■
INTERNAL CLOCK
• The internal clock data is stored in memory powered by a backup battery while the
73VR1100 is without external power supply.
• The data will be reset to its default status when the battery is used up while the 73VR1100
is left without power supply for a long time period. The clock adjustment will be nec
-
essary once the power is restored. Please refer to the 73VR1100 Users Manual (EM-
7399-C, Section 5) for the procedure.
• Once the power is restored, the 73VR1100 starts recharging the battery. It will be full
in approximately in 36 to 48 hours.
■
AND ....
• We recommend use of an UPS to supply power backups.
• The module is designed to function as soon as power is supplied, however, a warm up
for 10 minutes is required for satisfying complete performance described in the data
sheet.
