4.4 Using the Probe

1. Open the app, select the cooking food type, and set your desired taste preference.
2. Insert the probe into the center of the meat, ensuring the depth of insertion is beyond the safe cooking line engraved on the probe. Avoid bones or cartilage.

4. To stop the alarm, press the button on the base once or cancel it via the app. If no action is taken, the alarm will stop automatically after 1 minute.

NOTE:

• A safe cooking line is engraved on the probe body. Insert the probe into the meat until this line is exceeded. Keeping the probe tip unexposed will damage the probe.
• After cooking, do not immediately touch the hot probe. Use heat-insulated gloves or a tool to prevent burns.

5. Cleaning and Maintenance

• Store the product in a cool, dry place. Avoid direct sunlight, extreme temperatures (below 0°C or high), or high humidity to prevent damage.
• When cleaning the probe, use a non-corrosive detergent, wipe it dry, and then replace it on the base.
• Store the entire product in a cool, dry place away from children to prevent injury from the sharp probe.
• The base unit is NOT waterproof. Do not clean it with running water or place it in a dishwasher or water sink. Clean the base with a slightly damp cloth when necessary, preventing water from seeping in.
• If not using the product for an extended period, remove the batteries from the base and cover the battery compartment.

6. Important Notes and Warnings

• This product is NOT suitable for use in pressure cookers or microwave ovens.
• Keep the base unit away from fire sources, heat sources, and direct sunlight during use.
• Ensure the probe is inserted into the center of the food and deep enough to pass the safe cooking line, avoiding hard bones.
• Do not use the probe in cooking environments above 300°C (572°F) or below -10°C (14°F). Do not expose it directly to flame or burning wood charcoal, as this may damage the probe battery.
• During or at the end of cooking, do not touch the overheated probe with bare hands. Always use heat-insulated gloves or a tool if necessary.
• If the probe falls out of the food, stop heating immediately and remove the probe after it has cooled down.
• The product is designed exclusively for use as a food thermometer and is not recommended for any other purposes.

7. Troubleshooting Guide

7.1 Why Cannot Connect Bluetooth?

• Ensure your smartphone or tablet is running iOS 12 / Android 7.1 or later.
• Verify that Bluetooth is enabled on your smartphone/tablet and the thermometer's battery has sufficient power.
• Make sure the positioning function is enabled on your smartphone/tablet and the application is authorized to access location information.
• Ensure the distance between the probe and the base is not more than 6m (19.68ft), and the probe is placed near the base. Place your smartphone or tablet as close to the base as possible, avoiding any metal or obstructions.
• Confirm the thermometer is disconnected from any other smartphones and that Bluetooth is disabled on those devices.
• Restart the thermometer, open the app, and repeat the connection steps.
• Turn off any other Bluetooth devices or disable their Bluetooth functions within the connection range. If the issue persists, contact customer support.

7.2 Why Cannot Charge The Probe/Base?

• For the base: Correctly install two new AAA alkaline batteries according to polarity. Do not use rechargeable batteries.
• Check for battery leakage or rusty battery connectors in the base.
• Check for water seepage or humid surfaces on the batteries or battery compartment. Remove batteries, uncover the compartment, and wipe dry with tissues or blow dry with cool air.
• Ensure the charging contact point on the top of the probe is in contact with the charging plate on the base, and the probe is placed correctly.
• Check the probe's charging contact point for water droplets and moisture. Wipe dry and try again.
• Check if the probe or the charging plate on the base is rusty.
• Check that the probe has not been used in an environment where the temperature is above its bearable range, which could cause damage. Purchase a replacement if necessary.

7.3 Why Is The Probe Reading Incorrect?

• Check if the current temperature exceeds or has once exceeded the probe measurement range, which could cause damage.
• Do not immerse the probe in water for a long time.
• You can calibrate the temperature to what you believe is correct through the application.
