Why Does It Take So Long To Find Satellites?; How Do I Reset The Earthmate Pn-40 When It Will Not Turn Off?; Why Won’t My Lithium-Ion Battery Hold A Charge? - DeLorme Earthmate PN-40 User Manual

Other ways to increase the life of the batteries include:
• Removing your batteries for long-term storage
• Setting the GPS Settings to Power Saving mode
• Disabling GPS while indoors
• Using batteries with higher milliamp ratings (such as Duracell Ultras, Energizer E2s, etc.)
Why are the new batteries that I put in the device the last time I used it (a month ago)
already dead?
Because the Earthmate PN-40 has a real-time clock that requires power even when the device is
powered off, your batteries are constantly in use. To improve battery life if you use your Earthmate
PN-40 sporadically (more than a month between uses), remove the batteries for long-term storage
and then reinsert them when you want to use the device.

Why does it take so long to find satellites?

Acquiring satellite data takes longer if the batteries are low or if the Earthmate PN-40 does not
have a clear view of the sky. Be sure that trees, buildings, and other obstacles are not blocking the
Earthmate PN-40 when you begin tracking.
Other factors, such as if you haven't used the device for a long time or if you've moved the device a
great distance from its last location, can affect the amount of time it takes to find satellites.

How do I reset the Earthmate PN-40 when it will not turn off?

To reset the Earthmate PN-40, hold the Power button for seven seconds. If that does not work,
remove and replace the batteries to reset the Earthmate PN-40.
Why won't my Lithium-ion battery hold a charge?
The Li-ion battery is designed to last for 300-500 uses, depending on environmental conditions.
Where can I find tips and tricks for using my Earthmate PN-40?

Getting Started
Note: The charging circuit
in the Earthmate PN-40
was designed for optimum
operation with the RCR-V3
Li-Ion battery sold through
DeLorme. Other RCR-V3 Li-Ion
batteries may work and charge
in the device, but DeLorme
can make no guarantees of
compatible operation.
