5. Setup Guide
- Unpacking: Carefully remove the dry cabinet from its packaging. Inspect for any damage during transit.
- Placement: Place the cabinet on a flat, stable, and dry surface. Ensure there is adequate space around the cabinet for proper ventilation. Avoid placing it near windows or heating vents.
- Internal Organization: Open the cabinet door. Adjust the height of the internal shelves as needed to accommodate your equipment. The shelves can be removed or repositioned by lifting and sliding them into the desired slots.
- Power Connection: Connect the provided power adapter to the cabinet's power input port, typically located at the rear. Plug the adapter into a standard electrical outlet.
- Initial Power On: The digital display should illuminate, showing the current temperature and humidity inside the cabinet. Allow the cabinet to operate for a few hours empty to stabilize the internal environment before placing sensitive items inside.

6. Operating Instructions
- Understanding the Digital Display: The LCD display shows two main readings: temperature (in Celsius) and relative humidity (RH%).
- Adjusting Humidity Levels: Locate the humidity control knob, usually on the top panel or inside the cabinet near the display. Turn the knob to set your desired humidity level. The recommended range for most camera gear and electronics is between 35% and 50% RH. The cabinet will automatically work to achieve and maintain this level.
- UV Sterilization: The UV sterilization system operates automatically at regular intervals when the cabinet door is closed. This feature helps eliminate harmful microorganisms. No manual intervention is required for UV activation.
- Storing Equipment: Place your cameras, lenses, and other sensitive items inside the cabinet. Ensure items are clean and dry before storage. Arrange them to allow for proper air circulation. Close the door firmly to maintain the sealed environment.

- Cleaning: Regularly wipe the exterior with a soft, dry cloth. For the interior and glass door, use a slightly damp cloth and mild cleaner if necessary, then dry thoroughly. Avoid abrasive cleaners.
- Door Seal: Periodically check the door seal for any signs of wear or damage. A compromised seal can affect humidity control efficiency.
- Power Adapter: Ensure the power adapter is free from damage and securely connected. Avoid exposing it to moisture or extreme temperatures.
- Ventilation: Ensure the cabinet's ventilation openings are clear of dust and obstructions.
