Units / Position— allows you to configure the displayed data to standard or metric units of
measure. This setting applies to distance, speed, altitude, fuel, pressure and temperature. Also
provides three magnetic variation (heading) options: True, Auto or User-defined. If “Auto” is
selected, all track, course and heading information is corrected to the magnetic variation computed
by the GPS receiver. The “True” setting references all information to true north, and the “User”
setting corrects information to a user-entered value.
Configuration settings for position format and map datum are also provided. Position formats
include latitude/longitude, MGRS and UTM/UPS. The NavData® card contains over 100 map
datums to adjust your position reading, making it conform to specific paper charts. The default
datum setting is WGS 84. If you are using a chart based on another datum, you should set the GPS
500 to use the same datum. Using a map datum that does not match the charts you are using can
result in significant differences in position information. If you are using the paper charts for refer-
ence only, the GPS 500 still provides correct navigation guidance to the waypoints contained in the
database, regardless of the datum selected.

Date / Time— provides settings for time format (local or UTC; 12- or 24-hour) and time offset.
The time offset is used to define current local time. UTC (also called “GMT” or “zulu”) date and
time are calculated directly from the GPS satellites’ signals and cannot be changed. If you prefer to
use local time, simply designate the offset by adding or subtracting the correct number of hours.

Display Backlight— allows you to adjust the display for optimum viewing in any condition.
Automatic backlighting is available which uses a built-in photocell (at the top left corner of the
display bezel) to make the proper display adjustments without any user intervention. You may select
manual control of the display backlighting to tailor the GPS 500 display to your needs.
