Setup
Battery Installation
Your ThermoPro TP03H thermometer comes with one AAA battery. To install the battery, locate the battery compartment on the back of the device. Use a small screwdriver (often included) to open the battery cover. Insert the AAA battery, ensuring the correct polarity (+/-), then securely close the battery cover.

Operating Instructions
Basic Operation
To begin using your thermometer, simply unfold the stainless steel probe. The device will automatically power on. Insert the probe into the thickest part of the food, avoiding bone or gristle. The temperature reading will display on the LCD screen within 3-4 seconds.

Temperature Lock Function
Press the "LOCK/CAL" button once to lock the current temperature reading on the display. This is useful when you need to remove the probe from the food but want to retain the reading. Press the button again to unlock and resume live temperature monitoring.

Backlight Feature
Press the "LIGHT" button to activate the backlight for improved visibility in dimly lit environments. Press it again to turn the backlight off.
Unit Conversion (°C/°F)
To switch between Celsius and Fahrenheit, press the "°C/°F" button located near the power button.
Calibration
For accurate readings, it is recommended to calibrate your thermometer periodically. To calibrate, prepare a glass of ice water (ensure it's mostly ice with a little water). Hold the "LOCK/CAL" button for 5 seconds to enter calibration mode. Immerse the probe into the ice water and wait until the reading stabilizes at 32°F (0°C). The thermometer will automatically calibrate.

Recommended Internal Temperatures
For food safety and optimal taste, refer to the following recommended internal temperatures:
| Meat Type | Doneness | Temperature (°F/°C) |
|---|---|---|
| Beef | Well | 170°F/77°C |
| Beef | Medium | 160°F/71°C |
| Beef | Medium Rare | 145°F/63°C |
| Pork | Well | 170°F/77°C |
| Ham | Uncooked | 160°F/71°C |
| Poultry | 165°F/74°C |
Maintenance and Care
To ensure the longevity and accuracy of your ThermoPro TP03H thermometer, follow these maintenance guidelines:
- Cleaning: The thermometer has an IPX6 waterproof rating, allowing you to wash the probe under running water. However, avoid submerging the entire unit, especially the display and battery compartment, in water. Hand wash only.
- Storage: Fold the probe back into the unit for safe and compact storage. Utilize the magnetic back to attach it to metal surfaces like refrigerators, or hang it using the integrated hang hole.
- Battery: Replace the AAA battery when the display becomes dim or unresponsive.

Troubleshooting
- No Display/Dim Display: Check if the AAA battery is correctly installed or needs replacement.
- Inaccurate Readings: Perform a calibration using the ice water method as described in the Operating Instructions section. Ensure the probe is inserted into the thickest part of the food and not touching bone.
- Probe Not Folding/Unfolding Smoothly: Ensure no debris is obstructing the hinge mechanism. Clean if necessary.
