Operating Your BFOUR Thermometer
Probe Insertion
Always insert the probe into the thickest part of the meat, ensuring the safety notch on the probe is fully covered by the meat and the tip of the probe is inside the meat. Do not expose the ceramic handle or the probe's internal temperature sensor (located near the tip) to direct flames or temperatures exceeding 752°F/400°C for the handle and 212°F/100°C for the internal sensor.

Troubleshooting Tips
Connectivity Issues
- Ensure Bluetooth is enabled on your phone and the BF Home app has location permissions.
- Keep the booster station within 328 feet (unobstructed) of your phone and 196 feet (open environment) of the probes for stable connection. Metal or other obstacles can reduce signal range.
- Restart the app and/or the booster if connection problems persist.
Inaccurate Readings
- Verify that the probe is inserted correctly into the thickest part of the meat, past the safety notch.
- Ensure the internal temperature of the probe does not exceed 212°F/100°C, as this can damage the probe.
Battery Life
- Fully charge the probes and booster before extended use.
- Refer to the display for battery indicators.
