3. Setup
3.1 Battery Installation
Your ThermoMaven HT04 thermometer comes with one AAA battery pre-installed. To activate the thermometer for first use, ensure the battery compartment is securely closed. If replacing the battery, open the battery cover on the back of the device, insert a new AAA battery with the correct polarity, and close the cover.
3.2 Initial Activation
To turn on the thermometer, simply unfold the probe from its stored position. The display will automatically illuminate and show the current temperature.

4. Operating Instructions
4.1 Taking a Temperature Reading
- Unfold the probe to turn on the thermometer.
- Insert the thin tip of the probe into the thickest part of the food, avoiding bones.
- Wait approximately 0.5 seconds for the temperature to stabilize on the backlit display.
- To hold the current reading on the display, press the "LOCK" button located on the side of the device. Press again to release.
- Once finished, fold the probe back into the housing to turn off the thermometer. The device will also automatically power off after a period of inactivity.

4.2 Switching Temperature Units (°F/°C)
To switch between Fahrenheit (°F) and Celsius (°C), locate the small "C/F" button on the backside of the thermometer. Press this button to toggle between the two units.
4.3 Auto-Rotating Display
The display automatically rotates to ensure the temperature reading is always upright, regardless of the angle at which the thermometer is held. This feature enhances readability for all users.

5. Maintenance
5.1 Cleaning Instructions
The ThermoMaven HT04 is IP67 waterproof and designed for easy cleaning.
- Hand wash the probe and body with warm, soapy water.
- Rinse thoroughly under running water.
- Wipe dry with a clean cloth.
- Do not immerse the entire unit in water for extended periods, despite its waterproof rating.
- Do not place in a dishwasher.
5.2 Storage
Store the thermometer with the probe folded to protect it and conserve battery life. Utilize the integrated magnet to attach it to metallic surfaces (e.g., refrigerator) or hang it using the built-in hole.

6. Troubleshooting
- No Display: Ensure the probe is fully unfolded. Check if the AAA battery is correctly installed and has sufficient charge. Replace the battery if necessary.
- Inaccurate Readings: Verify the probe is inserted into the thickest part of the food, away from bones. Allow sufficient time (approx. 0.5 seconds) for the reading to stabilize. If issues persist, refer to the included calibration certificate for details on its NIST certification.
- Display Not Rotating: The auto-rotating display relies on motion. Ensure the thermometer is being moved or held in different orientations. If it remains static, the display may not rotate.
