Warning: There are no user-serviceable components inside the Maretron DSM570. Opening the
DSM570 will expose the sensitive electronic components to adverse environmental conditions that may
render the unit inoperative. Please do not open the DSM570, as this will automatically void the warranty.
If service is required, please return the unit to an authorized Maretron service location.
