Operating Instructions
1. Selecting Meat Type and Doneness (Pre-programmed Settings)
- Press the MEAT button to cycle through different meat types (e.g., Beef, Poultry, Pork, Fish).
- Once the desired meat type is selected, press the TASTE button to select the desired doneness level (e.g., Rare, Medium, Well Done). The target temperature will automatically adjust based on your selection.
2. Manual Temperature Setting
If you prefer to set a custom target temperature:
- Press the MODE button until the target temperature setting is highlighted or blinking.
- Use the MIN and SEC buttons (or up/down arrows if present) to adjust the target temperature to your desired value.
- Press MODE again to confirm the setting or to exit the setting mode.
3. Using the Timer Function
The thermometer includes a count up/down timer:
- To set a countdown timer: Press the MIN and SEC buttons to set the desired time. Press START/STOP to begin.
- To use as a count-up timer: Ensure the timer is at 0:00, then press START/STOP.
- Press CLEAR to reset the timer.
4. Inserting the Probe
Carefully insert the stainless steel probe into the thickest part of the meat, avoiding bones or gristle. Ensure the probe tip is fully embedded for accurate internal temperature readings.
5. Monitoring Temperature and Alarm
The current internal temperature of the meat will be displayed on the screen. When the meat reaches the set target temperature, an alarm will sound to notify you. The wireless range is approximately 30 meters (100 feet), allowing you to monitor from a distance.
