Security
The Security screen allows you to lock out the EDIT key in order to keep crew members
or visitors from changing settings that you have made. Once this feature is enabled, a
press of the EDIT key will require the correct password to gain access. To disable the
security functions, you will be prompted to enter a 5 digit password. You will then be
prompted to reenter the password. The security function is then disabled until you enter
a new password through the CFG1 Security screen again. Be sure to keep your password
in a safe place. If you lose your password, you will need to call the factory to reset the
security feature.

This menu provides a means to verify the status and baud rate settings of all the NMEA

Beacon receiver interface. You have no control in these two ports. You can not change
the baud settings in its original values.
