2.5.4.4 Installation Description...
The ALM100, along with all other Level A certified NMEA devices, has two user-programmable
installation description fields. You may program these fields with information specific to the
device, such as date installed, the initials/name of the installer, the physical location of the
device, etc. This configuration option will allow you to program the values of these fields.
3 Maintenance
Regular maintenance is important to ensure continued proper operation of the Maretron
ALM100. 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 ALM100 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.
