Introduction

Thank you for purchasing the OMRON Digital Thermometer Eco Temp Basic.
The thermometer you purchased offers a safe, accurate and quick temperature reading. You can measure your temperature either in the anus (rectally), in the mouth (orally) or in the armpit (axillary). This thermometer eliminates any worries about broken glass or mercury hazards. Note that your temperature is affected by smoking, eating or drinking.
Contact your doctor if you have any questions regarding specific temperatures.

Switching between Fahrenheit/Centigrade (Celsius)

Press the button for 7 seconds until a beep is emitted.
The display will change to the other measurement system at the time when the beep sounds.

Use of the thermometer

1. Press the button.
   
   The result of the previous measurement is displayed for a few seconds. Then 37.0°C (98.6°F) is displayed as an internal test-function.
   
   Note: When a temperature other than 37.0°C (98.6°F) is displayed, please refer to the "Display Indications and Troubleshooting" section for details to correct the problem.
2. Apply the thermometer to the measurement site.
   Note: Even if the "L" indicator fails to display (when only the temperature is displayed), this is not an error. The temperature may be taken as is.
   
3. 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.
   
   Buzzer notification timing
   Rectal: approx. 60 seconds
   Oral: approx. 80 seconds
   Armpit: approx. 2 minutes
   Notes:
   • The buzzer notification timing is based on an environmental temperature of 23 degrees.
   • Since oral and armpit may give lower measurement results it is recommended to apply the device rectally to get the most accurate result.
4. Turn off the thermometer. Clean and disinfect before returning it to its protective case.
   Notes:
   • The reading will automatically be stored in memory.
   • Turn off the thermometer manually to conserve the battery. It will automatically switch off 30 minutes after use or 3 minutes when turned on but not used.

Displaying the last temperature

Press the button to display the temperature that was measured most recently. For details, please refer to the "Use of the thermometer" section.

Correct measurement

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

Rectal use:

• Commonly used for small children when it is difficult to take an oral or armpit temperature.
• Lubricate with non-irritating skin-friendly gel.
• Gently insert the probe tip no more than 1.3 cm into the rectum. Do not force the tip into the rectum if resistance is encountered.
• Disinfect the thermometer after use.

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:

• Place the sensor tip in the centre of the armpit.
  
• Lock the sensor tip under the arm, using the arm to slightly apply pressure inwards.
  

The following may result in 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.

The following may result in incorrect measurements when taking armpit temperatures:

• Heavy armpit perspiration
  Correct: Wipe off any armpit perspiration before taking the temperature.
• Taking the temperature after being under the blankets for a long time.

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 cover.
   (Fig. 12)
2. Remove the battery.
   (Fig. 13)
3. Insert the new battery with the "+" pole facing up as shown in the diagram. Make sure the battery is put in with the right polarity.
   (Fig. 14)
4. Use a coin to replace the battery cover.
   (Fig. 15)
   Notes:
   • The thermometer comes fitted with a battery for testing purposes. This battery may not provide the same amount of battery life as a new battery.
   • Do not loose the O-ring around the screw. Water-resistant will fail and can lead to misreadings and failure of the unit.

Display Indications and Troubleshooting

Indicator	Cause	Remedy
(low)	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.
(high)	Displayed when the temperature of the sensing section is higher than than 42°C (107.6°F).	Cool the sensing section and then take the temperature.
Air Temperature Displayed	Displayed when the surrounding temperature exceeds 32°C (89.6°F).
[37.0°C (98.6°F)] is not displayed during the measurement preparation period as a test display, after the most recent measurement result is displayed.	Turn the thermometer on and off several times. If a temperature other than that in the range from [36.9°C (98.4°F)] to [37.1°C (98.8°F)] is displayed as a test display, please contact your nearest authorized OMRON dealer.

Storage

Store the thermometer in its storage case.
Do not store the thermometer in the following types of places. Doing so may damage the thermometer.

• Wet locations.
• Locations with high heat and humidity or those that are exposed to direct sunlight. Areas close to heating equipment, dusty locations, or environments where there are high salt concentrations in the air.
