View the Display Temperature
To view the current temperature of the display, select Terminal
Settings>Display>Display Temperature.
The 600 and 1000 terminals have a cold-cathode fluorescent lamp
(CCFL) backlight. This backlight requires temperature control when
the internal temperature of the product is below 10 °C (50 °F) or
above 60 °C (140 °F). The terminal monitors low and high
temperature conditions.
• If the internal temperature of the product is below 10 °C (50 °F),
the backlight is set to overdrive or the full-rated current setting
for at least five minutes.
• If the internal temperature is at or above 60 °C (50 °F), the
backlight is set to underdrive; 40% or less of full brightness. This
reduces heat generation from the backlight.
Temperature monitoring begins when the terminal powers on, or
when the backlight turns on, for example, exiting Screen Saver mode.
The temperature control affects only display intensity; it does not
restrict the use or operation of the terminal.
When a low or high temperature condition is detected, an error is sent
to the system event log. If the temperature control is not functioning,
a noncritical error is sent to the system event log but the terminal
continues to operate normally.
The CCFL backlight temperature control takes precedence over
