2. Setting the Time
- After installing the battery, locate the time setting knob on the back of the clock, usually near the battery compartment.
- Gently turn the knob to move the clock hands clockwise until the correct time is displayed.
- Ensure the hands are not obstructed and move freely.
3. Placement for Accurate Readings
For the most accurate temperature and humidity readings, hang the clock in a location that is:
- Out of direct sunlight.
- Away from direct heat sources (e.g., vents, heaters).
- Protected from direct rain or excessive moisture, even though it is weather-resistant.
- In an area with good air circulation.

Operating the Clock
Reading the Time
The clock features a traditional analog display with hour, minute, and second hands. The large, clear numbers ensure easy readability from a distance.
Reading Temperature and Humidity
The clock face includes two smaller analog gauges:
- Thermometer: Located on the right side, this gauge displays the ambient temperature in both Fahrenheit (°F) and Celsius (°C).
- Hygrometer: Located on the left side, this gauge displays the relative humidity (%RH).
Allow the clock to acclimate to its environment for at least 30 minutes after placement to ensure accurate readings from the thermometer and hygrometer.
Maintenance
Cleaning
To clean the clock, use a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these may damage the clock's finish or internal components.
Battery Replacement
When the clock hands begin to slow down or stop moving, it is an indication that the battery needs to be replaced. Follow the battery installation steps outlined in the Setup section to replace the AA alkaline battery.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock not working or hands stopped. | Dead or improperly installed battery. | Replace the AA battery, ensuring correct polarity. |
| Time is inaccurate. | Time was not set correctly or battery is low. | Manually reset the time. Replace battery if necessary. |
| Temperature/Humidity readings are inaccurate. | Clock is in direct sunlight, near a heat source, or in an area with poor air circulation. | Relocate the clock to a shaded area with good air circulation, away from direct heat or moisture. Allow 30 minutes for acclimation. |
