Maintenance; Troubleshooting - Maretron TMP100 User Manual

3 Maintenance

Regular maintenance is important to ensure continued proper operation of the Maretron
TMP100. Perform the following tasks periodically:
 Clean the unit with a soft cloth. Do not use chemical cleaners as they may remove
paint or markings or may corrode the TMP100 enclosure or seals. Do not use any
cleaners containing acetone, as they will deteriorate the plastic enclosure.
 Ensure that the unit is mounted securely and cannot be moved relative to the mounting
surface. If the unit is loose, tighten the mounting screws.
 Check the security of the cable connected to the NMEA 2000
necessary.
 Check the security of all of the probe connections on the top of the unit and tighten if
necessary.
