Backlight

(MAIN MENU → Settings → Backlight)
The Backlight setting is used to control the
brightness of the GPS screen. It has significant
impact on the battery life and is therefore
recommended that you choose a setting which you
find comfortable, not necessarily the brightest.
Filter Options:
Within the Backlight settings you will find options for
filtering your screen. These include options for use
at night and in strong sunlight:
• Red Filter: for night vision
Press the Red Filter button for night use to
preserve your night vision. This adds a red tint
to your screen so your eyes are protected from
viewing a bright screen in the dark.
To preserve night vision, use a low level setting.
Below 10%, the scale goes down in steps of 2%.
(Some text may become illegible using the red filter
with a backlight setting below 10%).
Sun Filter, then Normal
Select to return to the
daylight screen.
• Sun Filter: for strong sunlight
Press the Red Filter button to access the
Filter option. This gives your screen a higher
contrast and increases the levels of red, green
and blue, so it is easier to view your map in very
bright sunlight.
Note: With the Sun Filter your screen loses some
intricate map details in order to enhance the visibility of
the map in sunlight.
Select Normal to return to the daylight screen.
