PRECAUTION
Figure 1
Warning :
Read instructions thoroughly before using digital thermometer.
Choking Hazard: Thermometer cap and battery may be fatal if swallowed. Do not allow children
to use this device without parental supervision.
Do not use thermometer in ear. Designed use is for oral, rectal, and armpit (axilla) readings only.
Do not place thermometer battery near extreme heat as it may explode.
Note: Use of the probe cover may result in a 0.01℃(0.02℉) discrepancy from actual temperature.
Remove battery from the device when not in operation for a long time.
The use of temperature readings for self-diagnosis is dangerous. Consult your doctor for the
interpretation of results. Self-diagnosis may lead to the worsening of existing disease conditions.
Do not attempt measurements when the thermometer is wet as inaccurate readings may result.
Do not bite the thermometer. Doing so may lead to breakage and/or injury.
Do not attempt to disassemble or repair the thermometer. Doing so may result in inaccurate readings.
After each use, disinfect the thermometer especially in case the device is used by more than one person.
Do not force the thermometer into the rectum. Stop insertion and abort the measurement when pain is
present. Failure to do so may lead to injury.
Do not use thermometer orally after being used rectally.
For children who are two years old or younger, please do not use the devices orally.
If the unit has been stored at temperatures over 5℃～40℃(41℉～104℉), leave it in 5℃～40℃
(41℉～104℉) ambient temperature for about 15 minutes before using it.
