Replacing the batteries
The thermometer is supplied with two 1.5 V batteries type AA (LR 6).
For best performance, we recommend Duracell
® alkaline batteries.
Insert new batteries when the battery symbol appears on the display.
To open the battery compartment, depress the button in the door as shown
using a pen or other pointed object, while lifting the door. Remove the batteries
and replace with new batteries, making sure the poles are in the right direction.
Slide battery door back until it snaps in place.
To protect the
environment,
dispose of
empty batteries
according to
national or local
regulations.
Calibration
The thermometer is initially calibrated at the time of manufacture. If the
thermometer is used according to the use instruction, periodic readjustment
is not required. However, Welch Allyn recommends checking calibration on an
annual basis or whenever clinical accuracy of the thermometer is in question.
Procedures for checking calibration are outlined in the 9600 Plus Calibration
Tester (REF 01802-110) directions for use manual.
The above recommendations do not supersede the legal requirements. The user
must always comply with legal requirements for the control of the measurement,
functionality, and accuracy of the device which are required by the scope of
relevent laws, directives or ordinances where the device is used.
Manufacturing date is given by the LOT number located on front of the product.
The first three digits give the day of the year manufactured.The second two
digits give the year of manufacture.The last six digits represent the serial
number of the device.
An example: LOT 27710KTC this product has been manufactured on the 277 day of
the year 2010.
Special situations
Clinical studies have shown the Braun ThermoScan thermometer can obtain accurate temperature mea-
surements on full term newborn, pediatric and adult patients. However, there are special situations when an
ear thermometer should not be used. These include, but may not be limited to the following situations:
• Do not use an ear thermometer if there is blood or drainage in the external ear canal.
• An ear thermometer should not be used on a patient who exhibits symptoms of an acute or chronic
inflammatory condition of the external ear canal.
• Common situations like the presence of moderate amounts of cerumen in the ear canal, otitis media
and tympanostomy tubes do not significantly impact temperature readings. However, complete ear
canal occlusion due to cerumen can result in lower temperature readings.
• For persons using hearing aids or ear plugs, remove the device and wait 20 minutes prior to taking
a temperature.
• Use the untreated ear if prescription ear drops or other ear medications have been placed in the ear
canal.
• Patients who have deformities of the face and/or ear may not be able to have a temperature taken with
an ear thermometer.
Fever facts
Many persons may not have an elevated temperature even when they are ill. These include, but are not
limited to infants under 90 days of age, persons taking steroids, antibiotics or antipyretics (acetaminophen,
ibuprofen, aspirin), persons with compromised immune systems, including the elderly or persons with some
chronic illnesses.
Fever is described as an elevation of body temperature over an individual’s «normal» temperature.
An elevated temperature or fever is often viewed as a danger sign. In fact, a fever can be very beneficial,
and helps our
immune system work more effectively. A fever should be evaluated along with other physical symptoms.
With the exception of newborn infants, the presence of fever, without any other symptoms of illness, or in a
child who is behaving normally may not be cause of concern.
Some people, such as the elderly, infants under 90 days of age, those with compromised immune systems,
or persons who take steroids for example are often unable to build a response to illness or environmental
conditions. These individuals may not have a fever when they are ill, or their elevated temperature may
be lower than expected for the severity of their illness. Other medications such as antiinflammatories and
some analgesics may also mask fever.
The presence or absence of fever should not be used as the only measurement of the significance of the
illness.
Febrile seizures, or convulsions, which usually occur in children six months to six years of age, are thought
to occur not because a fever is present, but because of the rapid rise of the child’s temperature.
