PARTS OVERVIEW

IMPORTANT SAFETY NOTES

To assure the correct use of the product basic safety, measures should always be followed including the precautions listed below.

GENERAL SAFETY PRECAUTIONS

SWITCHING BETWEEN FAHRENHEIT/CENTIGRADE (CELSIUS)

Press the button for 7 seconds until a beep is emitted.

The display will change to the other measurement scale at the time when the beep sounds.

All of the display symbols appear.

The thermometer will automatically switch itself off.

TAKING THE TEMPERATURE

If possible, a full probe cover covering all sections should be used. Replace the probe cover with a new one after each use.
Probe covers are included with the thermometer, place a probe cover carefully over the tip.

1. Press the button.
   
   A default temperature 37.0°C (98.6°F) is shown up on display.
   NOTE: When a temperature other than 37.0°C (98.6°F) is displayed, please refer to the "TROUBLESHOOTING" section for details to correct the problem.
   
   All of the display symbols appear.
   The most recently measured temperature is displayed together with the M indicator.
   Waiting for use.

2. Apply the thermometer to the measurement site.
   Use the oral, rectal or underarm site for measurement.
   NOTE: Even if the "L" indicator fails to display (when only the temperature is displayed), this is not an error. So the temperature may be taken as is.
   
   When the [°C (°F)] indicator symbol blinks, the thermometer is ready for use.
   Temperature measurement will commence and the [°C (°F)] indicator symbol will blink.
3. For Oral and rectal measurement:
   When the reading is ready, the thermometer will emit a [beep-beep-beep] sound three times. Remove the thermometer from the measurement site and read the result.
   For underarm, please continue to hold for 2 - 5 minutes to complete the measurement.
   
   The [°C (°F)] indicator symbol will stop blinking and stay on when the reading is ready.

BUZZER NOTIFICATION TIMING:
Oral : approx. 20 seconds
Rectal : approx. 10 seconds
Underarm : approx. 25 seconds

* 25 seconds is the earliest estimated temperature indication. To complete the measurement, it is required to measure the temperature in the underarm between 2 - 5 minutes (depending on the ambient temperature and condition).

NOTES:

4. Turn off the thermometer and store it in the protective case.

NOTES:

DISPLAYING THE LAST TEMPERATURE

Press the button to display the temperature that was measured most recently. For details, please refer to the "TAKING THE TEMPERATURE" section.

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 attempting a reading.

RECTAL USE:

Always use a probe cover when taking rectal measurements.

UNDERARM (AXILLARY) USE:

• Place the probe tip in the center of the armpit.
  
  • Turn the display so that it faces inwards.
    
• Lock the probe tip under the arm, using the arm to slightly apply pressure inwards.
  
  • Thermometer Angle: The angle should be 35- 45 degrees in relation to the arm.
    

* In the case of infants and very young children, gently hold the arm to prevent movement.

INCORRECT MEASUREMENTS

• Taking the temperature immediately after exercising, bathing, eating or drinking will result in an incorrect measurement.
  Correct: Wait at least 30 minutes before taking the temperature.
• Taking the temperature after moving around.
  Correct: Take the temperature immediately after waking up or wait for at least 30 minutes after moving around.
  * Moving around after awakening increases the body temperature.

BATTERY REPLACEMENT

Battery: Alkaline-Manganese Button Battery LR41 (available commercially)

Battery Replacement Indicator ( )
Replace the battery when the battery replacement indicator appears when the thermometer is switched on.

1. Use a coin to take off the battery cover.
   
   
2. Remove the battery.
   
   
3. Insert the new battery with the "+" pole facing up as shown in the diagram.
   
   The "+" mark faces upwards
   
4. Use a coin to replace the battery cover.
   

NOTES:

• Do not loose the O-ring around the battery cover. Water-resistant will fail and can lead to misreading and failure of the unit.
  

ERROR DISPLAYS

INDICATOR	CAUSE	REMEDY
	Displayed when the temperature of the sensing section is less than 32°C (89.6°F).	This is not an error so it may be ignored and the temperature taken.
	Displayed when the temperature of the sensing section is greater than 42°C (107.6°F).	Cool the sensing section and then take the temperature.
Temperature Displayed	Displayed when the surrounding temperature exceeds 32°C (89.6°F).	This is not an error, so the temperature may be taken as is.

TROUBLESHOOTING

PROBLEM	CAUSE	CORRECTION
Wide differences in readings		Check to see that the thermometer is being placed at the location as described in the "CORRECT MEASUREMENT" section.
Nothing appears in the display section when the power switch is pressed.	The polarity is reversed.	Take out the battery and replace using the correct polarity.
	The battery is depleted.	Check to see if appears in the display section. Replace with a new battery (LR41).
[37.0°C (98.6°F)] is not displayed during the measurement preparation period.	A temperature from [36.9°C (98.4°F)] to [37.1°C (98.8°F)] is displayed.	The thermometer may be used as it is.
	A temperature other than that in the range from [36.9°C (98.4°F)] to [37.1°C (98.8°F)] is displayed, even after turning the thermometer on and off several times.	Please contact your nearest authorized OMRON dealer.
