BODY TEMPERATURE

Body temperature can vary during the course of a day and location of temperature reading. Normal body
temperature ranges from 97.0°F (36.1°C) to 99.0°F (37.2°C). The generally accepted “normal”
temperature is 98.6°F (37.0°C). Usually your temperature is lower in the morning than in the afternoon.

HIGH FEVER ALARM

This thermometer has a built-in fever alarm to warn users of higher than normal temperature. The fever
alarm will beep 1 long beep followed by 3 short beeps.

Operating Instructions

1. Gently squeeze the opposite ends of the thermometer to pull off the probe cap. Do not use force in

removing the cap.

2. Press the “ON/MEM” button (located below the LCD display).

3. The thermometer is ready for use after the ear icon stops flashing and

two beeps are sounded.

4. Gently pull the ear back to straighten the ear canal and snugly position

the probe into the ear canal, aiming towards the membrane of the
eardrum to obtain an accurate reading ( Fig.4-1)

5. Measuring the ear temperature: Use the index finger to hold the “Scan” button (located other side of

LCD display at the top) down until you hear a beep ( Fig. 4-2 ).

Figure 4-1 Figure 4-2

6. Remove the thermometer from ear, the temperature reading will display

on LCD screen.

7. To turn off thermometer, hold down “ON/MEM button until you see “OFF” on LCD display or device

will automatically shut off after 1 minute to extend battery life.

8. Replace probe cap after use.

Holding the thermometer too long may cause a higher ambient temperature reading of the probe.

This could make the body temperature measurement lower than usual.

Switching between Fahrenheit and Celsius
To change the LCD from °C to °F: When the unit is OFF, hold down the “Scan” button, then press

and hold the “ON/MEN” button until the LCD shows ‘°F’, then release the “Scan” button. Use the
same process to change the LCD display from °F to °C.

Memory Function

This ear thermometer can store up to 9 readings. The memory function allows you to make temperature
comparisons for evaluation of temperature trends.

Using Memory Function

1. If the reading of the thermometer is within the normal temperature range of 93.2 oF to 108.0oF (34oC to

42.2

** Press the “ON/MEN” button again to see the temperature stored.

2. To recall memory, press the “ON/MEM” button. The LCD display will show the temperature reading

stored in Memory 1.

3. Press “ON/MEM” button again to see the temperature stored in Memory 2. Repeat this process to see

temperature measurements stored in all memory locations.

Cleaning and Storage

The Probe is the most delicate part of the thermometer. Use with care when cleaning the probe to avoid
damage. Gently clean the exterior and LCD display with a mild solution and do not submerge unit in
water or any other liquids. Keep the unit dry and away from direct sunlight.
