OVERVIEW

Description

With its many functions, the Omron Digital Thermometer MC-670 is a popular option among both consumers and healthcare professionals. Its large, backlit LCD display makes readings clear and easy to see, and its thin and ergonomic form makes it pleasant to operate. This thermometer consistently produces quick and precise temperature readings, with a measurement period of only 60 seconds and an accuracy of ±0.1°F (±0.05°C).

SWITCHING BETWEEN FAHRENHEIT/CENTIGRADE (CELSIUS)

The thermometer default is set to Fahrenheit °F.
To change the measurement mode from °F (Fahrenheit) to °C (Centigrade), follow the procedure shown below. From the off position (blank display):

Press and hold the ON/OFF button for more than 5 seconds until F flashes on the display.
NOTE: If you do not change the measurement mode for more than 5 seconds after F or C starts flashing, the thermometer will automatically turn off .
Remove your finger from the ON/OFF button.
While “F” is still flashing, press the ON/OFF button to display “C”. (Each time the ON/OFF button is pressed, “F” and “C” are displayed alternately.)
After selecting desired mode (e.g. °C), leave the thermometer for 5 seconds until it turns off automatically.
The thermometer is now set for °C mode. All measurement readings from now on will be in °C.
To select °F mode, start from Step 1.

CORRECT MEASUREMENT

Measurement accuracy cannot be assured when the method used to measure the temperature is incorrect.

ORAL USE (for ages 4 and older):

The mouth should remain closed up to 5 minutes before starting a reading.

Place the thermometer in the mouth under the tongue so that it rests to the left or right of the root of the tongue.
Use downward tongue pressure to hold the thermometer in place.
Hold the thermometer to keep it from sliding around in the mouth.

ARMPIT (AXILLARY) USE:
