Operation
Measurement
Operation Read this user’s manual carefully before use and make sure the battery is properly installed. Pull and release the trigger to turn the thermometer on. The device will run a self-test and all symbols on the display will shortly appear. The device will default to the last mode used. To measure the body temperature, make sure the “Body temp” icon is on. If not, press the mode switch button to turn it on. Then aim the infrared lens at the individual’s forehead, holding the thermometer approximately 3-5cm away.
After pulling and releasing the trigger, the temperature reading will be displayed with a beep when the tone model is on. If the temperature measurement is below 32°C or 89.6°F, a “Lo” symbol will appear. If the reading is above 42.9°C or 109.22°F, a “Hi” symbol will be displayed. Meanwhile, the buzzer will send out a Di-Di-Di alarm when the tone model is on. The screen will change from green to red at the same time if the backlight is on. One more test would be applicable in both conditions.
If the reading is above 37.4°C or 99.32°F but below 38°C or 100.4°F the screen will change from green to yellow when the backlight is on. If the reading is above 38.1°C or 100.4°F the buzzer will send out a Di-Di-Di alarm when the tone model is on and the screen will change from green to red when the backlight is on. In the “surface temperature” mode, no “Body temp” icon is shown on the screen. This model can be used to display the true values of measure results which are either higher than 42.9°C (109.22°F) or lower than 32°C (89.6°F). The thermometer will automatically shut off after 20-second standby.
Maintenance
The body of the thermometer can be cleaned with a soft, dry cloth. Do not use water to wash the thermometer. Do not use cleaning agents other than alcohol, such as abrasives, thinners, or gasoline.
