If your operator panel 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:
- 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 connected LMU's (location messaging unit) GPS and COMM LEDs are ON constantly.
- Verify the connected LMU's wiring connection and that it is not loose or broken:
- Red wire to a constant +12 VDC.
- White wire to the vehicle ignition.
- Black wire to chassis ground.
- Customizable input wires are NOT connected to third-party systems such as video, child reminder, and AC.
- Red wire to a constant +12 VDC.
- Verify that the cable is securely connected between the LMU and the operator panel.
- 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 connected LMU is getting power.
- If the antenna is external, make certain that it is connected and damage free.
- Verify that the operator panel 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.
- Try swapping out the nonfunctioning LMU for a known working LMU in the vehicle.
- Try swapping out the nonfunctioning operator panel for a known working operator panel 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].)
