Antibacterial Thermometer
The Citizen Digital Thermometer CTA303 is fully compliant with the internationally recognized ISO22196 standard. The main body of the thermometer includes certain special materials, rendering it antibacterial.

PRECAUTIONS

1. The thermometer should only be used under the supervision of an adult.
2. Do not walk, run or talk during temperature taking.
3. Store the unit in the protective case when not in use.
4. Do not store the unit where it will be exposed to direct sunlight, dust or humidity. Avoid extreme temperatures.
5. Dropping or subjecting your thermometer to strong shocks should be avoided.
6. Do not attempt to disassemble the unit, except to replace the battery.

HOW TO SWITCH FROM ˚C TO ˚F (FROM ˚F TO ˚C)

Hold ON/OFF button for 2 sec. Display will activate and ˚C becomes ˚F.

HOW TO OPERATE

1. Press ON/OFF button to activate. The unit would beep and display.
2. Then, the temperature taken last time would be displayed with a "M" mark in the right corner.
3. Then, 37.0˚C (or 98.6˚F) will appear.
4. When Lo and flashing ˚C (˚F) displays, the thermometer is ready for temperature measuring. But if the room temperature is higher than 32.0˚C (89.6˚F), the room temperature would be displayed instead of Lo.
5. The beep will sound when temperature measuring is complete.
6. Press ON/OFF button to turn off the unit.
   (The unit will automatically power off after approximately nine minutes after use.)

Taking an oral temperature

Place the probe tip under the tongue and close the mouth.
Approximate measuring time: 1 minute.

Taking an axillary temperature (under the arm)

Wipe the underarm with a dry towel and place the probe tip under the arm so the tip is touching the skin with the thermometer perpendicular to the body. Position the arm across the chest so the probe tip is well covered by the arm.
Approximate measuring time: 2-3 minutes.
Note: Axillary temperatures are generally 0.5˚C /1.0˚F lower than oral readings.

Taking a rectal temperature

Apply a water-soluble lubricant to the probe cover. Gently insert the probe into the rectum.
Approximate measuring time: 1 minute.
Note: Rectal temperatures are generally 0.5˚C /1.0˚F higher than oral readings.
