Maintenance
1. Cleaning the Thermometer
To clean the thermometer, gently wipe the surface and the infrared probe with an alcohol swab or a cotton swab moistened with 70% isopropyl alcohol. Do not use abrasive cleaners or immerse the device in water. Ensure the thermometer is dry before storage.
2. Storage
Store the thermometer in a cool, dry place, away from direct sunlight, dust, and extreme temperatures. Keep it in its original packaging or a protective case when not in use.
3. Battery Replacement
When the low battery indicator appears on the display, replace both batteries with new ones of the same type (AAA). Dispose of used batteries according to local regulations.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Device won't turn on | Dead or incorrectly installed batteries. | Check battery polarity; replace with new batteries. |
| Inaccurate readings | Dirty probe, incorrect measurement distance, environmental factors (drafts, direct sunlight). | Clean the probe; ensure correct distance (0.2-2 inches); measure in a stable environment. |
| "LO" or "HI" displayed | Temperature is outside the measurable range. | Ensure the thermometer is used within its specified operating temperature range. |
| Display shows "Err" | System error or malfunction. | Remove batteries, wait 1 minute, then reinsert. If error persists, contact customer support. |
