- Check that the main power switch on the PowerQuest 3 is in the 'ON' position.
- Verify that the 'Protection On' light is illuminated. If not, the unit may not be functioning correctly.
- If the 'Overvoltage Protection' light is on, the unit has shut down. Unplug the PowerQuest 3 from the wall, wait, and plug it back in to reset.
- Check the circuit breaker in your home's electrical panel.
- Poor Audio/Video Quality:
- Ensure devices are plugged into the correct type of outlet (e.g., video devices into '4K/8K Video Optimized' outlets, amplifiers into 'High-Current' outlets).
- Verify that all cables are securely connected.
- Confirm that the 'Protection On' light is illuminated, indicating active noise filtration.
