Locating your current position
Please have your DPN-3500 to be outside to locate your current position. When you first start the
navigation device, you will hear the message saying “signal is too low”. It means the navigation has
not located a reliable GPS signal yet. It will be up to 2 ~ 5 minutes to find your current position.
If after five minutes, the navigation is not located a reliable GPS signal, you need to check if you are
in an open place without tall buildings or trees around you.
After GPS signal located the position, the GPS indicator will be in flashing GREEN.
GPS signal will be much faster and normally within a few seconds to find your position in the future
after the first time use.
