The main unit is powered by 3 x LR03 (AAA) 1.5V batteries, while the sensors are powered by 4 x LR03 (AAA) 1.5V batteries (not included). The package includes the wireless thermometer, a freezer sensor, a refrigerator sensor, and an operating instruction.

When used for the first time or every time the alarm is turned off, the alarm function needs to be manually activated again. Otherwise, the alarm will not take effect. The display screen will turn off after 10 seconds of inactivity to save power.

The wireless thermometer is designed for both refrigerators and freezers, with a 3.7-inch high-definition LCD screen that supports the simultaneous display of the temperatures, MAX/MIN values, and temperature alarm icons. The 2-minute delayed alarm feature ensures that the thermometer only sounds when the temperature is outside the set range for more than 2 minutes, helping to avoid false alarms.

The MAX/MIN value records can be stored for 24 hours or all-time, providing more reference for your life and travels. The temperature unit can be easily switched between Celsius and Fahrenheit using the ℃/℉ button.

The wireless thermometer is battery-powered and easy to use, with the option to hang it on the wall or place it on a table. The alarm range in refrigeration mode is 0°C to 15°C, and the alarm range in freezing mode is 0°C to -40°C.
