Encryption
Tap System / Encryption. To prevent sensitive data on a CF or SD
storage card from being used if the card is lost or stolen, files can be
encrypted as they are placed on the card and will only be readable on
the unit that they were encrypted. If you put a check in the checkbox,
the files saved thereafter will only be readable on this unit. It will not
be possible to read these files on the storage card by any other device
or even from a PC. Files saved on storage cards before enabling
encryption will not be encrypted.
NOTE: if you perform a Clean Boot on your unit, previously
encrypted files on storage cards will no longer be readable by that
unit or by any other device, including PCs.
GPS
Tap System / System Information / Wireless to see if your unit
has a built-in GPS If you do, COM2 is the dedicated hardware
port and GPS Address shows the COM port. (COM1 is dedicated
to the external 9-pin.)
To allow your unit to use multiple GPS-aware applications to
obtain GPS data simultaneously, your unit can manage access to
your GPS. If you are using only one GPS-aware application, the
following settings do not need changed.
To use multiple GPS-aware applications, tap System / GPS and
select the following tabs:
Access: The GPS Intermediate Driver is disabled by default.
To enable, check the box "Manage GPS automatically
(recommended)".
Hardware: If you have an internal GPS in your unit, COM2 is
the hardware port dedicated for the internal GPS. Verify
COM2 is selected. The internal GPS communicates at 9600
baud by default, though you may need to adjust the baud rate
to match the baud rate that the receiver is set to.
Programs: Programs that use GPS need to know which port to
use to access GPS data. Ensure that the COM port on the GPS-
aware application is set to the same port as shown in the
