How do I reset the TLA100 to send the factory default messages (or PGNs)?

You reset the TLA100 to transmit the factory default messages using Maretron's DSM250 display in the following way:

1. Enter menu mode, scroll to "Configuration:" and press < Enter >
2. Scroll to "Device Configuration:" and press < Enter >
3. Scroll to the row containing the TLA100 and press < Enter >
4. Scroll to "Reset Factory Defaults" and press < Enter > twice.

Beware that resetting factory defaults resets all settings back to factory defaults, not just the transmitted messages.
