| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or dim. | Low or dead batteries; incorrect battery polarity; no USB power. | Replace batteries with new ones, ensuring correct +/- orientation. Check USB cable connection and power source. |
| Time or date is incorrect. | Not set correctly; internal clock drift. | Re-enter setting mode and adjust time/date as per Section 5.2. Note that minor time drift (a few minutes over several months) can occur with some digital clocks. |
| Temperature reading seems inaccurate. | Clock placed near heat/cold source; minor sensor variation. | Ensure the clock is placed in an area with stable ambient temperature, away from direct heat or cold sources. The temperature display provides an approximate ambient reading. |
