If your MDT-7P device seems to be failing, before returning it to Synovia, first try the following troubleshooting steps to make sure that something else other than the hardware isn't causing the problem:


  1. Check for GPS data:
     
    • Make sure that the vehicle has a clear view of the sky.
       
    • Check that the vehicle ignition key is in the ON position.
       
    • Verify that the timestamp is displayed onscreen.
       
  2. If the timestamp isn’t displayed, check the following:
     
    • Verify that the cable is securely connected between the LMU (location messaging unit) and the MDT (mobile data terminal).
       
    • Verify that the cable leads into the correct Aux port as defined in the script (usually Aux 2). (If the LMU is a 3640, this will be Aux 1.)
       
    • Verify that the antenna is securely connected to the LMU and that it has acquired COMM.
       
    • Verify that the LMU is getting power.
       
    • Verify with your Synovia project manager that the appropriate MDT license was activated for your account.
      Note: License changes that affect the peripheral type will take effect on the next nightly reboot.
    • Verify with your Synovia project manager that the peripheral type/ESN for the vehicle is accurate and set to CalAmp 7P.
       
    • Press the top center edge of the screen and slide down to display the running processes. Verify that CMF Connection Status reads, "LMU is connected."
       
  3. Reboot the MDT by pressing and holding down the power button on the top right corner of the device and selecting the Reboot option.
     
  4. Verify that the MDT is reporting to Synovia. Log in to Synovia on a computer or mobile device and see if events are being reported for the vehicle and that it appears in its current location on the map.
     
  5. Try swapping out the nonfunctioning LMU for a known working LMU in the vehicle.
     
  6. Try swapping out the nonfunctioning MDT-7P for a known working MDT-7P in the vehicle.


If you've tried all these troubleshooting steps and the device is still malfunctioning, you can open a ticket at CalAmp K-12 Support Portal. (You can find more details at Returning Hardware and Obtaining a Replacement [Performing an RMA].)
