Maintenance, storage and calibration
Maintenance
This thermometer is not a waterproof device. To clean the thermometer,
wipe gently with a soft, dry cloth.
Don’t wash with water or detergent
containing abrasive or benzene.
Don’t touch or blow the infrared sensor. A polluted infrared sensor may
cause inaccuracy. If you need to clean a polluted infrared sensor, use a soft
cloth in a gentle manner. Cleaning with toilet tissue or a paper towel may
scratch the infrared sensor, which will cause inaccuracy.
Storage
When not in use, you can put the thermometer into the stand.
Don’t leave the thermometer exposed to or at risk of direct sunshine, high
temperatures, dampness, fire, vibrations or heavy impact.
If the thermometer is not used for any length of time, we recommend
removing the batteries.
Calibration
This thermometer is calibrated at the time of manufacture. If the unit is used
according to the instructions, periodic recalibration is not required. If at any
time you question the accuracy of the measurement, please contact RNIB.
Don’t attempt to modify or reassemble the thermometer, as this will
invalidate the product guarantee.
Hints and Tips
•
If the battery symbol appears on LCD display: low batteries. Insert new
batteries.
•
If “Lo” or “Hi” is displayed on the screen: make sure the thermometer is
correctly pointed at the eardrum or the forehead and follow the
instructions for taking a measurement.
•
There’s no response: Are the batteries low? If so, install new batteries.
Are the batteries inserted incorrectly? Adjust batteries to correct polarity.
•
ErrP or ErrH appears on the LCD display: this would show a hardware
problem. Contact RNIB.
