Operating Instructions
- Prepare the Probe: Remove the wireless probe from the base unit.
- Insert the Probe into Food: Insert the probe into the thickest part of the meat, avoiding bones. Ensure the probe is inserted deep enough so that the internal sensors are fully within the food, and the ambient sensor (if applicable, usually near the handle) is exposed to the cooking environment.
- Place the Base Unit: Position the thermometer base unit near the cooking appliance (grill, oven, smoker). For optimal Bluetooth connection, keep the base unit within 100 meters of the probe. For WiFi, the range is extended via your home network.
- Set Target Temperature:
- Using the Base Unit: Use the buttons on the base unit to manually set your desired target temperature. The display will show the current internal and ambient temperatures, along with your set target.
- Using the BFOUR+ App: Open the app on your smartphone. Select the connected thermometer. Choose from predefined meat profiles and doneness levels (e.g., Beef, Medium Rare) or set a custom target temperature.
- Monitor Temperature:
- The thermometer base display will continuously show the current internal food temperature and the ambient cooking temperature.
- The BFOUR+ app will provide real-time temperature graphs, estimated cooking times, and alerts.
- Alarm Notification: Once the internal food temperature reaches your set target, both the thermometer base and the app (if connected) will trigger an audible and/or visual alarm.
- Remove Probe: Carefully remove the probe from the food using heat-resistant gloves.
- Power Off: Press and hold the power button on the base unit to turn it off when not in use.
