Power Management
You can set how the backlight will behave when the screen has not
been touched for a while. You have the following options:
•
Backlight Always On: The screen is continuously lit.
•
Smart: When running on battery, Smart Powersave will light up
the screen only when you tap the screen, or if there is
something to show you. After a few seconds the light level
decreases, and after another few seconds the backlight turns
off. This helps achieve a longer battery life.

Description
Update Interval
This determines how often track points will be saved. Position
information is normally received once a second from the GPS. If you
do not need such a detailed log, you can increase this number to save
track log space.
Enable Auto-saving
When auto-saving is enabled, you do not need to turn track log saving
on and off manually. AZ291MA will automatically start recording the
track log as soon as GPS position is available.
Track Log Database Size
This figure shows how much memory is used by the automatically
saved track logs.
Track Logs Max. Size
You can set the maximum database size for the automatically saved
track logs. When the limit is reached, the oldest automatically saved
track logs will be deleted.
Create NMEA/SIRF Log
Independently of the normal track log, you can instruct AZ291MA to
record the native GPS data received from the GPS device. These logs
are saved as separate text files on an inserted memory card, and they
cannot be shown or replayed in AZ291MA.
