MODES, BUTTONS AND DISPLAY
Timer Readout
The Timer is a standard counter that records
a maximum of 99 hours, 59 minutes, and
59 seconds. The Wayfinder can be used
as a timer while still maintaining accurate
compass readings.
"DISTORTION" Icon
The Wayfinder detects when outside magnetic
interference is
accuracy and displays the "DISTORTION"
icon in the upper left corner. Distortion
occurs when there has been a significant
change in the surrounding magnetic fields,
such as when you are driving underneath an
compromising compass
overpass or over a bridge. The steel in these
structures causes inaccurate readings in any
magnetic compass, but the Wayfinder detects
this interference and alerts you.
Backlight
The Wayfinder uses an electro-luminescent
backlight to illuminate the display, making it
easily visible at night. Pressing the ADV and
ENT buttons at the same time turns the back-
light on or off. The backlight has a program-
mable shut-off, which turns the backlight off
after it has been on for a specified period of
time. To conserve battery power, the backlight
should be turned off when not in use.
