1.10.5 Time and Time Zones
GPS reports its time as UTC time (which is essentially Greenwich Mean time). Your local time will
probably vary from UTC time by a number of hours. For example, during non-Daylight-Saving
time in the U.S., the eastern time zone is UTC time – 5 hours. (There are some places where the
difference may be in 30- or even 15-minute increments – for example, Nepal is UTC + 5:45.)
The GPX has a menu item which allows setting the local time. It uses the UTC time as reported by
the GPS as the basis, and, using the arrows, you can increase the time of day (press Right) (UTC +)
or decrease the time of day (press Left) (UTC -) in 15-minute increments until the time shown is
correct for your local time. Then press Select to finalize your selection. This time will then be
stored with your laps, and this “difference from UTC” will remain as a setting in the GPX until you
change it.
The default main screen displays the current date and time. However, until the GPS acquires a
good signal from the satellites, "Date/time N/A" (not available). As soon as a good signal is
acquired, the display will update to the current date and time.
1.10.6 Battery and Charging
The internal Li-Ion battery, when fully charged, will usually power the device for about 3-4 hours.
(This time may be shorter due to excessive use of the backlight or the tach lights.)
The battery is charged whenever the device is connected to a 12V source through the external
cable, or whenever it is connected via the USB port.
