Backlite Max Brightness
MENU  Display Settings .. Backlite Max Bright
This setting is used in conjunction with the Backlite Mode setting.
When the Backlite Mode is set to Fixed, this setting directly sets the fixed Backlight Brightness Level.
When the Backlite Mode is set to Automatic, this setting becomes the Maximum Backlight Level and the brightness is
automatically adjusted between Minimum and Maximum light levels according to ambient light levels. Changes are reflected
immediately. Avoid covering the sensor window with your thumb while making adjustments.
Note:
If the internal temperature should reach 140ºF, UltraGauge will automatically dim the display to 65%. The Backlight is
responsible for most of the internal heat and reducing the brightness to 65% significantly reduces this heat. Once the
temperature falls below 136ºF, the display brightness will return to the user configured settings.
Ambient Sensitivity
MENU  Display Settings .. Backlite Max Bright
When the Backlite Mode is set to Automatic, this setting is used to set UltraGauge’s sensitivity to the vehicle’s inside cabin
ambient light level. Vehicles with tinted, smaller or fewer windows will have lesser ambient light levels. This setting allows
UltraGauge to be tailored to your vehicle’s light levels. This setting has a range of from 0-100, with 100 being the most
sensitive. As the sensitivity is increased, UltraGauge becomes more responsive to lower light levels. At a setting of 0,
UltraGauge must capture significant light before it begins to increase the Backlite level. At a setting of 100, a very insignificant
amount of light causes UltraGauge to increase Backlight Levels.
Since this setting is very relative, it must be adjusted experimentally for your vehicle. While using UltraGauge, if the Maximum
backlight brightness is not achieved in ambient light that you believe should produce Maximum Backlight brightness, increase
the sensitivity by 5 and watch the results. Repeat until satisfied. Changes are reflected immediately.
Note: On the front right hand side of UltraGauge there is an opening which UltraGauge uses to capture ambient light. Avoid
covering the sensor window with your thumb while making adjustments.
Note: If the sensitivity is set to high, the UltraGauge will be too bright for nighttime driving.
Adjust LCD Contrast
MENU  Display Settings .. Adjust LCD Contrast
Use this menu item to fine tune the contrast of the display. Ideal contrast is achieved when the text brightness is maximized
and the background brightness is minimized. Changes to the contrast setting are instantly updated on the display. Once the
ideal contrast is reached, press Menu to exit.
