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.

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 reaches +32°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).

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.
