Troubleshooting

My device does not turn on

• Push the power cable all the way into the back of the device.
Even if the cable seems to be connected, you should push firmly so that it
is fully seated.
• Make sure the power source is generating power.
You can check this several ways. For example, you can check whether
other devices powered by the source are functioning.
• Check the fuse in the power cable.
The fuse should be located in a holder that is part of the red wire of the
power cable. Check that the proper size fuse is installed. Refer to the label
on the cable or the installation instructions for the exact fuse size needed.
Check the fuse to make sure there is still a connection inside of the fuse.
You can test the fuse using a multimeter. If the fuse is good, the multimeter
reads 0 ohm.
• Check to make sure the device is receiving at least 10 Vdc, but 12 Vdc is
recommended.
To check the voltage, measure the female power and ground sockets of
the power cable for DC voltage. If the voltage is less than 10 Vdc, the
device will not turn on.
