Setup
1. Battery Installation (for compatible BFOUR Thermometer Unit)
Ensure your BFOUR Bluetooth thermometer unit (sold separately) has 3 AAA batteries installed. Refer to your thermometer unit's manual for specific battery installation instructions.
2. Connecting the Probes
- Carefully unwrap the probe cable from its winder.
- Insert the 3.5mm jack of the probe cable into any available port on your BFOUR Bluetooth thermometer unit. The unit will automatically detect the connected probe.
- Repeat for the second probe if using multiple probes.
3. App Installation and Pairing
Download the 'Grill Thermometer' app (or 'Grill 5.0' as indicated in some manuals) from your smartphone's app store. Once installed and opened, the app will automatically connect to your BFOUR Bluetooth thermometer unit after the initial pairing process. Ensure Bluetooth is enabled on your smartphone.
Operating Instructions
1. Powering On the Thermometer Unit
Press and hold the power button on your BFOUR thermometer unit to turn it on. The display will illuminate, showing current temperature readings.
2. Inserting Probes into Food
Insert the pointed end of the stainless steel probe into the thickest part of the food, avoiding bones. Ensure the probe tip is fully embedded for accurate readings.

3. Monitoring Temperature via App
The 'Grill Thermometer' app provides a clear interface to monitor temperatures. You can select from various preset food types (e.g., Beef, Chicken, Pork, Fish) with recommended doneness temperatures, or set custom target temperatures. The app displays the current temperature, target temperature, and a progress graph. If multiple probes are connected, the app will display readings for each probe separately.
4. Probe Responsiveness
The BFOUR probes are designed for quick response times, allowing for rapid temperature updates on both the unit's display and the connected app.
Maintenance
1. Cleaning
After each use, allow the probes to cool. Wipe clean the stainless steel probes and aluminum alloy handles with a damp cloth. Do not immerse the probe connectors or the main thermometer unit in water. Ensure all parts are dry before storage.
2. Storage
Utilize the provided probe winders/organizers to neatly store the probes and cables when not in use. This helps protect the probes and prevents cable tangling, ensuring their longevity and readiness for the next use.
