Rhodan HD GPS Anchor+ Preventative Maintenance Guide

CAUTION: ALWAYS REMOVE ELECTRICAL POWER WHEN PERFORMING MAINTENANCE

After Each Use:

  1. Remember to unplug and remove ALL electrical power sources from your Rhodan HD GPS Anchor+ prior to conducting maintenance or charging your battery system. NEVER leave your Rhodan HD GPS Anchor+ system UNATTENDED while connected to electrical power or not in use.
  2. Wash down with fresh water and dry with a clean, soft cloth. *DO NOT use a pressure washer or jet stream of water to wash down the unit*
  3. Ensure the prop is free and clear of any seaweed, fishing line, or debris. This will damage the seal and result in lower unit failure if not removed. Use a small amount of Vaseline or marine-grade lubricant on the prop shaft. *Never use power tools to remove or install props. Hand wrench only. Use caution removing and installing props as they have sharp edges. We recommend using hand protection (gloves) when handling the prop/lower unit* Use caution to NOT drop the prop pin. Torque the locking prop nut to 5 ft-lb when reinstalling.

Monthly:

  1. Lubricate the shaft with Vaseline or a clear marine-grade lubricant 8-12” above lower unit connection to the shaft.
  2. Wipe down the data cable and power cable with a UV protectant.
  3. Inspect cables for any broken cable insulation. Repair as needed with an approved electrical tape.
  4. Inspect/clean battery terminals for corrosion. Check connections for tightness.
  5. Ensure your batteries are being charged on a regular basis. Low battery voltage will affect the performance of your Rhodan HD GPS Anchor+ unit. *NEVER charge the battery system while your Rhodan HD GPS Anchor+ is connected*
  6. Remove the side covers and rear cover on the base unit with a Phillips screwdriver. Inspect electrical connections and cradle linkage for corrosion. Clean if necessary. Lubricate cradle linkage with Vaseline or an aerosol marine-grade lubricant on moving parts.
  7. Remove the head cover and inspect for corrosion, water, and component wear/power connections. Wipe clean and dry using water only.
  8. DO NOT overtighten the cover bolts during the reinstallation process.

Annually OR when moving from vessel to vessel:

  1. Check FOB battery voltage. Proper voltage is 3.2V. Replacement battery part number is CR2032. Coat the edge of the green FOB membrane with Vaseline to provide a proper water-resistant seal. DO NOT over-tighten the FOB Shell screws. *Recommended Annually*
  2. Perform Compass Manual Calibrations. See Owners Manual for details.
  3. Perform Centering Calibrations. See Owners Manual for details.
  4. Check mounting brackets for broken or loose fasteners or cracks.
