Troubleshooting Steps When Your Lowrance HDS Won’t Power Up

You’ve identified the potential issues, and now it’s time to roll up your sleeves and get to work. Here’s a step-by-step guide to troubleshooting your Lowrance HDS power problems.

Checking the Power Source

The first step in troubleshooting is always to check the power source. Your Lowrance HDS unit needs a steady supply of power to function correctly.

How to check the power source:

  1. Inspect the power cables for any visible damage.
  2. Check the connection between the device and the power source.
  3. If you’re using a battery, make sure it’s charged and functioning correctly.

Performing a Soft Reset

If the power source isn’t the issue, a soft reset may do the trick. A soft reset can resolve software glitches that might be preventing your device from powering up.

Steps to perform a soft reset:

  1. Press and hold the ‘PAGES‘ button
  2. While holding ‘PAGES‘, press and release the ‘POWER‘ button
  3. Release both buttons when the USA map appears.

Please note, a soft reset will not delete your waypoints or other user data.

Performing a Hard Reset

If the soft reset doesn’t work, you may need to try a hard reset. This will restore the unit to its factory settings.

Steps to perform a hard reset:

  1. Press and hold the ‘ZIN’ & ‘ZOUT’ Buttons at the same time.
  2. Press and release the ‘POWER‘ button while still holding ‘ZIN’ & ‘ZOUT’.
  3. Release all buttons when the USA map appears.

Remember, a hard reset will delete all your data, so it’s best to back up any important information before performing a hard reset. If none of these steps work, it’s time to call in the experts. Reach out to Lowrance customer support or a trusted technician.
