Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Unit won't turn on. | Batteries are dead or incorrectly inserted. | Replace batteries with new ones, ensuring correct polarity. |
| Inaccurate temperature readings. | Probe not fully inserted; probe damaged; probe tip not in the center of the thickest part of the meat. | Ensure probe is fully inserted. Check probe for visible damage. Re-insert probe into the correct part of the food. |
| No connection between Main and Auxiliary Unit. | Units are out of range; interference; low batteries. | Move units closer together. Avoid placing near strong electromagnetic sources. Replace batteries in both units. |
| Alarm not sounding. | Volume too low or muted; target temperature not set. | Check device settings for alarm volume. Ensure a target temperature is set for the active probe. |
