Flush Mounting the Device

NOTICE

Be careful when cutting the hole to flush mount the device. There is only a small amount of clearance between the case and the mounting holes, and cutting the hole too large could compromise the stability of the device after it is mounted.

The included template and hardware can be used to flush mount the device in your dashboard. There are three options for hardware based on the mounting surface material.

  • You can drill pilot holes and use the included wood screws.

  • You can drill holes and use the included nut plates and machine screws. The nut plates can add stability to a thinner surface.

  • You can punch and tap holes, and use the included machine screws.

  1. Trim the template, and make sure it fits in the location where you want to mount the device.
  2. Secure the template to the mounting location.
  3. Using a 13 mm (1/2 in.) drill bit, drill one or more of the holes inside the corners of the solid line on the template to prepare the mounting surface for cutting.
  4. Using a jigsaw or a rotary tool, cut the mounting surface along the inside line on the template.
  5. Place the device in the cutout to test the fit.
  6. If necessary, use a file and sandpaper to refine the size of the cutout.
  7. If necessary, remove the trim caps.
    NOTICE

    Use a plastic pry tool when possible. Using a metal pry tool, such as a screwdriver, can damage the trim caps and the device.

  8. After the device fits correctly in the cutout, ensure the mounting holes on the device line up with the larger holes on the template.
  9. If the mounting holes on the device do not line up, mark the new hole locations.
  10. Based on your mounting surface and model, drill or punch and tap the larger holes:

    • For the included wood screws on 702 models, drill 2 mm (5/64 in.) holes, and skip to step 18.

    • For the included wood screws on 902 models, drill 3.2 mm (1/8 in.) holes, and skip to step 18.

    • For the included nut plate and machine screws, drill 6 mm (1/4 in.) holes in the larger hole locations.

    • For the included machine screws without the nut plate on 702 models, punch and tap M3.5 holes, and skip to step 18.

    • For the included machine screws without the nut plate on 902 models, punch and tap M4 holes, and skip to step 18.

  11. If you are using a nut plate, starting in one corner of the template, place a nut plate Callout number one over the larger hole Callout number two drilled in the previous step.

    The smaller hole Callout number three on the nut plate should line up with the smaller hole on the template.

  12. If the smaller hole on the nut plate does not line up with the smaller hole on the template, mark the new hole location.
  13. If you are using a nut plate, drill a 4 mm (3/16 in.) hole in the smaller hole location.
  14. Repeat to verify placement of the remaining nut plates and holes on the template.
  15. Remove the template from the mounting surface.
  16. Starting in one corner of the mounting location, place a nut plate Callout number four on the back of the mounting surface, lining up the large and small holes.

    The raised portion of the nut plate should fit into the larger hole.

  17. Secure the nut plates to the mounting surface by fastening the smaller machine screws Callout number five through the smaller holes.
  18. Install the foam gasket Callout number six on the back of the device.

    The pieces of the foam gasket have adhesive on the back. Make sure you remove the protective liner before installing them on the device.

  19. If you will not have access to the back of the device after you mount it, connect all necessary cables to the device before placing it into the cutout.
    NOTICE

    To prevent corrosion of the metal contacts, cover unused connectors with the attached weather caps.

  20. Apply marine sealant between the mounting surface and the device to properly seal and prevent leakage behind the dashboard.
  21. If you will have access to the back of the device, apply marine sealant around the cutout.
  22. Place the device into the cutout.
  23. Secure the device to the mounting surface using the larger machine screws Callout number seven or the included wood screws.
  24. Wipe away all excess marine sealant.
  25. Install the trim caps by snapping them in place around the edges of the device.
