Operating Instructions
1. Inserting the Probe
Insert the stainless steel probe into the thickest part of the meat, ensuring the portion up to the arrow (or groove) is fully inside the meat. The black ceramic handle should remain outside the meat. Avoid inserting the probe directly into bone or gristle, as this can affect accuracy.

2. Using the VeSync App for Cooking
- Select Meat Type & Doneness: Open the VeSync app and select the type of meat you are cooking (e.g., beef, poultry, fish) and your desired doneness level (e.g., rare, medium, well-done). The app provides built-in presets for various options.
- Choose Cooking Appliance: Specify your cooking appliance (e.g., oven, grill, smoker, air fryer).
- Monitor Progress: The app will display the internal temperature of your meat, the ambient temperature of your cooking environment, and an estimated remaining cook time.
- Receive Alerts: Get real-time alerts on your phone for important cooking stages, such as when to flip the meat, when it's nearing completion, and when it's ready to be removed for resting.

3. Resting the Meat
Once the meat reaches its target temperature and the app alerts you, remove it from the heat source. The app will then guide you through the resting period, which is crucial for juices to redistribute, ensuring a tender and flavorful result. The probe can remain in the meat during resting to continue monitoring temperature changes.

Maintenance
Cleaning the Probe
The food-grade stainless steel probe is designed for easy cleaning. After each use, allow the probe to cool down. Wash the probe with warm, soapy water or place it in the dishwasher. Do Not Soak the entire probe, especially the black ceramic handle, as this can damage the internal electronics. Ensure the probe is completely dry before returning it to the charging block.
Charging Block Care
Wipe the charging block with a dry or slightly damp cloth. Do not submerge the charging block in water. Store the probe in its magnetic charging block when not in use to keep it charged and ready for your next cooking adventure.
Troubleshooting
1. Connectivity Issues
If the thermometer frequently disconnects from the VeSync app, ensure your smartphone is within close proximity to the charging block. Bluetooth range can be affected by obstacles like walls or large metal appliances. Try moving your phone closer to the cooking area or repositioning the charging block.
2. Inaccurate Temperature Readings
Ensure the probe is inserted correctly into the thickest part of the meat, avoiding bone or gristle. The probe should be inserted past the marked line to ensure accurate internal temperature readings. If the ambient temperature reading seems off, verify that the black ceramic handle is not touching any hot surfaces inside the oven or grill, as this can cause false readings.
3. Probe Not Charging
Check that the AAA battery in the charging block is correctly installed and has sufficient power. Ensure the probe is properly seated in the charging slot. The charging block should indicate charging status (e.g., an LED light).
