How to Troubleshoot a KVH LM

How to Troubleshoot a KVH LM thumbnail
A KVH LM is used to find the locations of satellites.

A KVH LM is a device that you can install on your motor home to identify and track the location of DirecTV and Dish Network satellites when traveling. This type of device is used to find the location of satellites so you will know where to point the satellite dish for the best reception. You can troubleshoot problems with your LVH LM by first determining the type of problem you have, such as no reception or device lockups.

Things You'll Need

  • Garden hose
  • Rag or cloth
  • Dish soap

Instructions

  1. No Reception

    • 1

      Go onto the roof of the vehicle and check to see if water is collecting on top of the unit. Water that does not flow off of the device can cause a signal disruption.

    • 2

      Connect a garden hose to a water valve on your motor home and spray down the KVH LM to remove any dew or condensation. Dry the device with a towel or cloth.

    • 3

      Check the satellite to determine if you can see a clear picture on the television.

    • 4

      Apply a small amount of liquid dish soap to a clean cloth or rag. Rub the dish soap over the unit and let the soap dry. The soap creates a film that will bead up water and moisture so that it will run off the unit.

    • 5

      Check the satellite signal after a rain storm to see if you receive a clear signal. Repeat step 4 every two weeks to prevent water from collecting on the unit.

    Device Lockups

    • 6

      Turn on the device and wait to see if it enters Search Mode 1 after about one minute. This indicates the satellite receiver or IRD data port may be locked up.

    • 7

      Turn off the power to the KVH LM. Unplug the unit from the DC power source. Unplug the power cord for the satellite receiver or IRD from the wall outlet.

    • 8

      Wait at least 10 seconds and then plug the power cord back in to the satellite receiver or ID and then turn the unit on.

    • 9

      Plug the KVH LM back into the DC power source. Check the satellite signal on the TV to see if the problem has been corrected.

Tips & Warnings

  • Do not make turns with the vehicle when the KVH LM is powering up because the turning motion can cause the antenna on the unit to track the satellites incorrectly.
