Motorola MW800 Series, Руководство пользователя, Страница: 22 / 29

Operating the MW 800 Display 15
heater will raise the MW 800 Display temperature to within its
operating range). You may also turn the workstation off and try again
at a later stage.
In extreme temperatures above +122°F (50
°
C), the workstation will
not power up.
SVGA Display Option
If the ambient temperature is in the +122 to +167°F (+50°C - +75°C)
range, the temperature LED will blink and the MW 800 Display will
power up, but the display brightness level will be approximately one
third of the maximum level. If the temperature drops to the operating
range the display brightness will be restored.
If the ambient temperature is in the -4 to +32°F (-20°C - 0°C) range,
the temperature LED will blink and the backlight heater will start
operating. When the CCFL (Cold Cathode Fluorescent Lamps)
temperature r32°F (0°C) (after approximately 2 minutes) the
MW-800 will automatically turn on.
If the ambient temperature is in the +30 to +68°F (0°C - +20°C)
range, the backlight heater will operate and the MW 800 Display will
turn on at once. The heater turns off when the CCFL temperature
reaches 122°F (50°C).
Operating in Extreme Temperature Conditions
XGA Display Option
If, during normal operation, the ambient temperature deviates from
the normal operating range, the temperature LED will blink. When
the temperature returns to within the operating temperature range, the
LED will be turned off.
A special temperature management mechanism prevents the
MW-800 from reaching extreme hot or cold temperatures. This is
achieved using a clock throttling technique and an internal heater.
