1. Introduction
The AYMDKI FM2118 Smart Wireless Meat Thermometer is designed to provide precise temperature monitoring for various cooking methods. This device features an ultra-thin probe, a digital display base, and Bluetooth connectivity for real-time monitoring via a mobile application. It is suitable for use with BBQs, grills, smokers, ovens, air fryers, stovetops, and sous-vide cooking.
2. Safety Information
- Always insert the probe into the thickest part of the meat, ensuring the notch and tip are fully covered by the meat for accurate readings.
- If wrapping meat in aluminum foil, ensure the probe needs to be exposed outside the foil. Otherwise, the signal may be blocked, causing the probe to disconnect.
- Place the dock (repeater) at least 1 foot (30 cm) away from the cooking grill or oven to avoid potential damage from excessive heat.
- The distance between the probe and the base needs to be less than 3 feet (1 meter) when the lid of the grill or oven is closed to prevent disconnection.
- The probe is high-temperature resistant, supporting grilling and high-heat baking. Probes withstand up to 707°F for 2 minutes, and 572°F for up to 20 minutes.
- Keep the device and its components out of reach of children.

5. Operating Instructions
5.1. Inserting the Probe
Carefully insert the ultra-thin probe into the thickest part of the meat. Ensure the probe is inserted up to the white line or notch on the probe shaft. This ensures accurate internal temperature readings and protects the internal components of the probe from excessive heat.

Select your meat type and doneness, and the app will provide recommended target temperatures and real-time alerts. The app also displays internal temperature trends and battery levels for both the probe and the base.
