Normal Temperatures According To Measurement Method

How to Take a Temperature

1. Press the “ON/OFF” button. The display will read “188.8 ” confirming that the unit is working. An “Err” message indicates the unit is not working properly.

2. The unit automatically displays the last reading and “M” icon on the right for approx.2 seconds with a green or red backlight.

3. The display will show LO with a flashing °C icon and a flashing measurement mode icon.

4. Press the M button continuously to select the appropriate mode from oral mode, Axilary mode and Rectal mode .Release the M button, the thermometer is now ready for use.
   Note: For the first use after insert /replacing a new battery,the unit automatically displays LO with “M” icon for approx 2 seconds. Then LO shows with °C flashing to indicate it’s ready for use.
   Please select the appropriate mode in 5 seconds after the display shows LO with flashing°C icon and flashing mode icon

5. Press and hold “ON/OFF” button, then press M button till the green backlight turns off. Release these 2 buttons and press “ON/OFF” button to switch temp. unit between°C, °F.

Reading the measurement

The Digital Thermometer comes with fever alert feature that offers a colour indicator with a readout to better understand the measurement.

• For reading below 37.5 °C, the LCD will display a green backlight colour for approx. 3 seconds and 3 short beeps will sound indicating that the measured temperature is within an acceptable range.
• For readings above 37.5 °C , the LCD will display a red backlight for approx.3 seconds and 3 long beeps will sound indicating a possible fever

Oral Use

• Do not drink hot or cold fluids, exercise or perform other activities that will raise or lower temperature readings when compared to your child’s normal, average temperature.
• Place the probe tip well under the tongue. Instruct children not to bite the thermometer.
• The peak temperature should be reached in approximately 8 seconds. Opening the mouth or improper placement of the probe tip could result in a longer time for reading

Underarm (Axillary) Use

1. Wipe underarm with a dry towel.
2. Place probe tip in armpit and bring arm down against the body (See Figure A). The probe should be pointing upward in the same direction as your body if possible.
3. The time required for an accurate underarm temperature may be 8 seconds or longer depending on placement of the probe and closure of the arm against the body.

Rectal use

This is the most reliable measuring method, and is especially appropriate for infants and small children. Carefully insert the tip of the thermometer 1.3 cm into the anal aperture.

Changing the battery

When the appears in the lower right of thedisplay, the battery is exhausted and need replacement. Make sure to replace with a same type of newbattery and proceed as follows: Remove the rear screw on the battery compartment cover using a suitable Phillips screwdriver.Remove the battery compartment cover. Replace with a new battery of the same type. Insert the new battery into the battery compartment in the correct polarity ensuring it is correctly positioned with the “+“ facing up. Carefully replace the battery compartment cover. Properly dispose of the old battery, keeping it away from young children and heat.
