Equipped with a clock display.

Celsius to Fahrenheit conversion.

High accuracy and intuitive display.

Time display range: 1:00-12:59

Temperature range: -50°C (-58°F) to +70°C (158°F)

Accuracy: ±1°C

Resolution: >-20°C corresponds to 0.1°C, ≤-20°C corresponds to 1.0°C

Instructions:

1. Open the battery cover on the body and install battery #1. Do not install it backwards.

2. FSW is the function switch. When displaying the indoor temperature, "IN" is displayed simultaneously, and when displaying the outdoor temperature, "OUT" is displayed simultaneously.

3. Upon startup, the LCD screen will display the full display for 2 seconds, then display the current indoor temperature. During the 2-second LCD display, the function key

does not change state.

4. If you hold the FSW function key for more than 4 seconds, it will turn off. However, the clock timer will continue to count down.

5. During measurement, if the temperature is greater than or equal to 70°C (158°F), the LCD screen will display H°C (°F) to one decimal place. If the temperature is less than -50°C (-58°F), the LCD screen will display H°C (°F) to one decimal place. The digit will display L°C (°F).

6. If the battery is insufficient, the LCD screen will flash at a rate of 1 Hz, and the battery must be replaced if measurement is not permitted.

6. (°C/°F) is the Celsius/Fahrenheit switch, which can be selected depending on the brand.

7. Setting the time:

①First press the FSW button to switch the LCD screen to the time display.

②Setting the hour (HR button): Press once to increase by 1 hour; if it exceeds 12, it will continue counting from 1.

③Setting the minutes (MIN button): Press once to increase by 1 minute; if it exceeds 59, it will continue counting from 00.

8. A is a built-in sensor probe, which can measure the temperature around the body (inside).

9. B is the sensor probe outside the machine. Place the probe where the temperature needs to be measured, and the temperature value will be displayed on the LCD screen.
