GPS Accuracy
In the lower left corner of tne Satellites Page, the GPS
accuracy displays. This is the calculated accuracy of the
GPS, expressed in distance. The actual location is within
plus or minus the distance indicated of the location
represented by the GPS.
On the Map Page, GPS accuracy is represented by a
circle with a radius equal to the GPS accuracy; your
actual location on the map is within the circle.
Any buildings, natural structures, or heavy foliage that
obstruct the GPS antenna’s view of the sky may prevent
satellite signals from reaching the receiver and decrease
the accuracy of your position. Placing the PN-Series GPS
in a jacket or backpack pocket should not affect positional
accuracy.
Battery Indicator
The battery indicator depicts the available battery power:
 Four green bars–Indicates a full charge.
 Three green bars–One quarter of the battery power
has been used.
 Two yellow bars–One half of the battery power has
been used.
 One red bar–Three quarters of the battery power has
been used. Once the battery has reached 5% of its
total battery power, a low battery warning displays.
When a DeLorme Li-ion battery is charging, the battery
indicator graphic is animated and the word “Battery”
is replaced with “Charging.” Once the battery is fully
charged, the battery indicator graphic displays four static
green bars and “External” displays until you disconnect
the USB cable.
If you are not using the DeLorme Li-ion battery, "External"
displays whenever you plug your device into your computer.
Elevation
PN-40 Only
The elevation is based on the current barometric altimeter
reading. When the Auto Calibrate Altimeter option is
enabled, you may see the word “Calibrating” in the bottom
right corner of the screen while the altimeter adjusts—
typically 2-3 minutes. If you are using the Elevation:
Altimeter info field on any page, you may see a red
exclamation point in the field while the altimeter adjusts.
For more information about calibrating the altimeter,
see Altimeter Calibration on page 68.
