Installer Tips & Troubleshooting

• Back-light glare? Angle the door station slightly and enable DWDR for better face exposure.
• Faint audio? Check cable gauge/length and tidy terminations; adjust monitor volume.
• Unlock not triggering? Confirm relay wiring, lock voltage/current and any required separate PSU for high-draw locks.
• Moisture ingress? Always fit the rain cover and seal per the quick start guide to keep IP66.
