Introduction
The ThermoPro TP20B is a professional-grade wireless meat thermometer designed to help you cook your food to perfection every time. Featuring dual probes and an extended 500FT wireless range, it allows you to monitor two different temperatures simultaneously, whether it's two cuts of meat or one cut and the ambient temperature of your grill, oven, or smoker. Its user-friendly interface and pre-programmed USDA-approved temperature settings ensure hassle-free operation and precise results.

Setup
1. Battery Installation
Locate the battery compartments on the back of both the receiver and transmitter units. Insert the provided AAA batteries, ensuring correct polarity (+/-). Close the battery covers securely.
2. Connecting Probes
Plug the stainless steel probes into the corresponding jacks on the side of the transmitter unit. The TP20B supports two probes, allowing for simultaneous temperature monitoring.

3. Powering On
Press the power button on both the receiver and transmitter units to turn them on. The units are pre-paired from the factory, so no manual synchronization is required. They should automatically connect and display temperature readings.
Operating Instructions
1. Selecting Meat Type and Doneness
The TP20B comes with preset USDA-approved temperatures for various meat types and doneness levels. Use the MEAT button to cycle through different meat options (e.g., Beef, Poultry, Pork, Lamb, Fish, Ham, BBQ). Once a meat type is selected, use the TASTE button to choose your desired doneness level (e.g., Rare, Medium Rare, Medium, Well Done).

2. Custom Temperature Settings
If you prefer to set your own target temperature, press the MODE button until "PROG" appears. Use the UP and DOWN arrow buttons to adjust the target temperature for each probe. Press MODE again to confirm.
3. Timer Function
The TP20B includes a kitchen timer function. Press the MODE button until the timer icon appears. Use the UP and DOWN arrows to set the desired time for either count-up or count-down. The receiver will beep and flash when the timer expires.

4. Fahrenheit/Celsius Switching
To switch between Fahrenheit (°F) and Celsius (°C) temperature readings, press and hold the °F/°C button on the receiver unit.
5. Using Dual Probes
The dual probes allow for versatile monitoring. You can insert one probe into a cut of meat and the other into a different cut, or use one probe for meat and the other with the included grill clip to monitor the ambient temperature of your grill, oven, or smoker. The receiver will display both temperatures simultaneously.

6. Wireless Range
The TP20B offers an extended wireless range of up to 500 feet, allowing you to monitor your cooking from a distance. Factors such as walls, appliances, and other electronic devices may affect the actual range.

Care and Maintenance
- Cleaning Probes: Always wipe the stainless steel probes with a damp cloth after each use. Do not immerse the probe connectors or the main units in water.
- Cleaning Units: Wipe the receiver and transmitter units with a damp cloth. Do not use abrasive cleaners or submerge them in water. The receiver is splashproof, but not waterproof.
- Probe Wire Care: The probe wires can withstand temperatures up to 716°F (380°C). Avoid exposing the wires directly to open flames or temperatures exceeding this limit, as it may damage the insulation.
- Storage: Store the thermometer and probes in a dry place when not in use.
Troubleshooting
- No Signal/Connection Issues:
- Ensure both the receiver and transmitter units are powered on.
- Check battery levels in both units and replace if low.
- Move the receiver closer to the transmitter to reduce interference.
- Avoid placing the transmitter near large metal objects or strong electromagnetic sources.
- Inaccurate Temperature Readings:
- Ensure probes are fully inserted into the thickest part of the meat, avoiding bone or gristle.
- Verify that the probe wires are not damaged or kinked.
- Test probes in boiling water (should read approx. 212°F / 100°C) or ice water (should read approx. 32°F / 0°C) for calibration check.
- Alarm Not Sounding:
- Check if the alarm volume is set appropriately (if adjustable).
- Ensure the target temperature is correctly set and the current temperature has reached or exceeded it.
