3. Safety Information
Please observe the following safety precautions to prevent injury or damage to the thermometer:
- Do not immerse the thermometer display unit in water or place it in a dishwasher. The probe is designed for immersion, but the main unit is not waterproof.
- Handle the stainless steel stem with care, as it will become very hot during use. Always use oven mitts or heat-resistant gloves when handling the probe after it has been exposed to high temperatures.
- Keep batteries out of reach of children. If swallowed, seek immediate medical attention.
- Do not expose the thermometer to extreme temperatures outside its specified operating range (14°F to 450°F / -10°C to +232°C).
- Ensure the probe tip does not touch the bottom or sides of the pot, as this can lead to inaccurate readings and potential damage to the probe from direct heat.

6. Operating Instructions
6.1 Power On/Off
The thermometer automatically powers on when the probe is inserted into a liquid or when a button is pressed. It will automatically power off after a period of inactivity to conserve battery life.
6.2 Temperature Unit Selection (°F/°C)
To switch between Fahrenheit (°F) and Celsius (°C), locate the F/C button on the display unit and press it. The display will change accordingly.
6.3 Using Preset Candy Stages
The DTC450 comes with 7 preset candy stages for common sugar temperatures:
- Soft Ball
- Firm Ball
- Hard Ball
- Soft Crack
- Hard Crack
- Caramel
- Jelly
To select a preset stage, press the 'MODE' button repeatedly until the desired stage is displayed. The thermometer will then monitor the temperature and alert you as it approaches and reaches the target.
6.4 Programmable Temperature Setting
In addition to preset stages, you can set a custom target temperature:
- Press the 'MODE' button until the programmable stage (often indicated as 'TEMP' or 'PROG') is selected.
- Use the 'SET' or arrow buttons (if available) to adjust the target temperature to your desired value.
- Confirm the setting (if required, by pressing 'SET' again or waiting for the display to revert).
6.5 Audio/Visual Alerts
The thermometer provides three types of alerts:
- Pre-Alert: A red LED flashes approximately 3 degrees before the target temperature is reached, providing an early warning.
- Target-Alert: An audible alarm and flashing light indicate when the set temperature has been reached.
- Over-Alert: If the temperature exceeds the target, a distinct alarm will sound, indicating that the candy stage has been passed.
