you purchased offers a safe, accurate and quick temperature reading. Y ou can measure your temperature through oral, rectal or
underarm. This thermometer
eliminates any worries about broken glass or mercury hazards. Note that your temperature is affected by smoking, eating
or drinking. Thoroughly
read this instruction manual before using your OMR ON MC-341 Digital Thermometer . W e recommend that you practice

have any questions regarding specific temperatures.
ANT SAFETY NOTES
o assure the correct use of the product basic safety, measures should a lways be followed including the precautions listed below .
A high or prolonged fever requires medical attention, especially for young children. Please contact your doctor .
Carefully read and follow the enclosed instructions to ensure accurate temperature readings. Note that temperature readings are affected by many
factors including physical
exertion, the drinking of hot or cold beverages before measurement, as well as measuring technique.
Please keep still during measurement.
The use of temperature readings for self-diagnosis is dangerous. Consult with your doctor for the interpretation of results. Self-diagnosis may lead to
the worsening of
existing disease conditions.
This thermometer is used for taking temperatures through oral, rectal or underarm. Do not attempt to take temperatures at other sites, such as in the
, as it may result in false readings and may lead to injury .
Store the thermometer out of the reach of children. Do not allow children to take their temperatures unattended. Children may injure themselves when
take temperatures without supervision.
Do not leave the battery , battery c over or probe c over where children can get to them. Children may swallow them. Should a child swallow the
, battery c over or probe c over, contact a doctor immediately .
Do not attempt measurements when the thermometer is wet as inaccurate readings may result.
Do not bite on the thermometer. Doing so may lead to breakage and/or injury.
Do not share the thermometer among individuals.
Do not attempt to disassemble or repair the thermometer. Doing so may result in inaccurate readings.
Do not attempt to incinerate the battery . It may burst.
Pay attention to polarity (+ –) when replacing the battery . Failure to do so may lead to fluid leakage, heat generation or bursting, resulting in damage
Rem ove the battery when the thermometer will not be used for 3 months or more. Failure to do so may lead to fluid leakage, heat generation or
bursting, resulting in
damage to the unit.
Do not use mobile phones near the thermometer .
Do not use the thermometer in places
strong static electricity or electromagnetic fields are present. Doing so may lead to inaccurate readings
contribute to instrument failure.
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 attempt rectal measurements on persons with rectal disorders. Doing so may aggrav ate or worsen the disorder.
Do not step on the unit or the hard case.
Do not attempt to disinfect the sensing section of the thermometer by immersing in alcohol or in hot water (water over 50°C).
Failure to use a probe c over may lead to bacteria and viral infection.
Do not use the thermometer to measure anything other than human body temperatures.
Do not drop the thermometer and protective case or expose them to shock or vibration.
Do not store the thermometer in the protective case when it is damp. Wipe it off with a dry cloth first.
