6. Operating Instructions

6.1 Power On/Off

The thermometer powers on automatically once the battery is installed. There is no dedicated power button.

6.2 Switching Temperature Display (Room/Fridge)

Press the ROOM/FRIDGE button to toggle between displaying the ambient room temperature (measured by the main unit) and the temperature measured by the external probe (e.g., inside a fridge or freezer).

6.3 Changing Temperature Unit (°C/°F)

Press the °C/°F ADJ button to switch the temperature unit between Celsius (°C) and Fahrenheit (°F).

6.4 Setting High/Low Temperature Alarms

The thermometer can alert you if the temperature goes above or below your set limits.

1. Press the ALERT SET button once. The "HI-AL" indicator will flash, and the current high alarm setting will be displayed.
2. Use the °C/°F ADJ button to adjust the desired high temperature limit.
3. Press ALERT SET again to confirm the high limit and move to the low alarm setting. The "LO-AL" indicator will flash.
4. Use the °C/°F ADJ button to adjust the desired low temperature limit.
5. Press ALERT SET a third time to confirm the low limit and exit alarm setting mode.
6. When the temperature exceeds the high limit or falls below the low limit, an audible alarm will sound, and the corresponding "HI-AL" or "LO-AL" indicator will flash.
7. To silence the alarm, press any button.

6.5 Using the Memory Function (MAX/MIN)

The thermometer records the maximum and minimum temperatures measured since the last reset.

1. Press the MAX/MIN button (located on the back) once to display the maximum recorded temperature.
2. Press MAX/MIN again to display the minimum recorded temperature.
3. Press MAX/MIN a third time to return to the current temperature display.
4. To clear the recorded MAX/MIN temperatures and start a new record, press and hold the MAX/MIN button for approximately 2 seconds while viewing either MAX or MIN temperature.
