• Relative Humidity: Displayed as a percentage (% RH). The reading updates approximately every 10 seconds.

The device does not have a backlight.

4.3 Placement and Mounting

For accurate readings, place the unit in the desired location, avoiding:

• Direct sunlight or heat sources (e.g., radiators, vents).
• Areas with direct moisture or splashing water.

Mounting Options:

• Standing: Place on a flat, stable surface.
• Wall-Mounting: Use the provided double-sided adhesive tape. Clean and dry the surface before applying.
• Embedded Mounting: The unit can be fitted into a pre-cut opening measuring 1.81" x 1.06".

4.4 Battery Replacement

2. Open the battery compartment on the back of the unit.
3. Remove the old batteries and insert two new LR44 batteries, ensuring correct polarity.
4. Close the battery compartment. The display will reset and show current readings.

5. Care and Maintenance

• Clean the unit with a soft, dry cloth. Do not use liquids or abrasive cleaners.
• Do not disassemble the unit beyond the battery compartment.
• For long-term storage, remove the batteries.

6. Troubleshooting

• No Display: Check that batteries are correctly installed and not depleted. Replace with new LR44 batteries.
• Inaccurate Readings: Ensure the unit is not placed near a direct heat, cooling, or moisture source. Allow several hours for the unit to acclimate to a new environment.
• Display is Foggy or Condensed: This may occur if the unit is moved from a cold to a warm environment rapidly. Allow it to adjust to ambient conditions; condensation should clear naturally.
