7. Troubleshooting

If you encounter issues with your Retekess TH201 intercom system, consider the following:

• No Power: Ensure the power adapter is securely connected to both the intercom unit and a working power outlet. If using a power bank, verify it is charged and properly connected.
• No Communication: Check that both intercom units are powered on and set to the same channel and code. Ensure they are within the maximum operating range (1 mile). Obstructions like thick walls can reduce range.
• Poor Audio Quality: Move units closer together or adjust their positions to minimize interference. Ensure the volume is set to an appropriate level.
• Interference: If experiencing interference, try changing the channel on both units.
• Unit Unresponsive: Try turning the unit off and on again. If the issue persists, disconnect power for a few minutes and then reconnect.

8. Maintenance

To ensure the longevity and optimal performance of your Retekess TH201 intercom system, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the units. Avoid using harsh chemicals or abrasive cleaners.
• Storage: When not in use for extended periods, store the units in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: If using D batteries, ensure they are replaced when low to maintain performance. Remove batteries if storing the unit for a long time to prevent leakage.
• Avoid Moisture: The units are not water-resistant. Keep them away from water, high humidity, and wet environments.
