Revision to Cobra SPX 5300 Troubleshooting

Olivia Breazeale

The detector is not wireless and must be plugged into a power source. If the device will not turn on, your power cord connecting the device to your cigarette lighter outlet may be faulty. Pull the cord out and reinsert it multiple times. If there is still no response, you should check the cord in a different outlet. If there is still no response, you may want to buy a new power cord.

If the power cord was not the issue, the cigarette lighter fuse may be. To check this, unscrew the tip of the cigarette lighter plug and make sure that all of the fuses are connected properly. If they are connected, test your device’s power cord in a different cigarette lighter within the vehicle to ensure that the power cord is not the problem. If they are not connected, the fuses may need to be replaced or repaired.
If the mute button is not pressed and there are still no alerts issued from the Cobra SPX 5300 Radar Detector, the speakers might be faulty. You will want to replace them.

The Cobra SPX 5300 is very sensitive to positioning within the car. In order for the device to receive a strong signal from radars, it must be level on the windshield and have an unobstructed view. If the device is not positioned in that way, it may not receive any signals.
