6.6 Backlight

(MAIN MENU → Settings → Backlight)

The Backlight setting is used to control the

brightness of the GPS screen. It has signicant

impact on the battery life and is therefore

recommended that you choose a setting which

you nd comfortable, not necessarily the

brightest.

Filter Options:

Within the Backlight settings you will nd

options for ltering 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 lter with a backlight

setting below 10%).

Select Sun Filter, then Normal to return to

the daylight screen.

• Sun Filter: for strong sunlight

Press the Red Filter button to access the

Sun 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.

The Red Filter, Sun Filter and Backlight

level can be used in combination to suit your

individual needs.

• Use the joystick, moving left/right to select

the desired level.

• Press Done or centre press the joystick to

return to SETTINGS MENU.

Pressing the Default button restores the

following setting: 90%

Note: If you are in Advanced Power Saving

mode, the Backlight setting cannot go beyond

80%.
