Questions and Answers
1. The temperature indicated is rather high.
• The unit has been stored in a cold room.
When the unit has been stored in a cold room, the measured temperature may be rather high if you measure
the temperature shortly after bringing the unit to a room that is at normal temperature. Measure temperature
after leaving the unit for 30 minutes in the room where it will be used. It is recommended to store the unit in
the room where you are going to measure temperature.
• The probe lens has been exposed to direct sunlight.
• Measurement was taken shortly after the subject cried. Crying can increase facial temperature.
2. The temperature indicated is rather low.
• The skin is wet.
Do not use the unit when wet after swimming, bathing, or through sweating after physical exercise, as skin
temperature may have fallen. Wipe away moisture and allow 30 minutes for the body to acclimate to room
temperature before measuring.
• The probe lens is dirty.
• Measurement was taken in surface temperature mode.
Use forehead measurement mode.
• Measurement was taken shortly after the subject was outdoors in cold weather.
Wait until the forehead has warmed up.
• Measurement was taken at a location other than the forehead.
Be sure to measure exactly at the forehead, not surrounding areas such as the hairline.
