Rapid clinical thermometer SC 42 TM  
with flexible measuring point and fever alarm 
We congratulate you  on the purchase  of this  quality product from  Scala. Please 
read the instructions for use before using for the first time. 
Special features: 
The SC  42 TM is a maximum thermometer, i.e. the  highest temperature is 
displayed  after  only  30  seconds.  The  most  recent  measured  value  is  always 
saved. If the temperature registers higher than 37,5°C the fever alarm will sound. 
Safety information: 
♦  The SC 42 TM is suitable only for measuring human body temperatures. 
♦  The  thermometer  contains  small  parts  (batteries,  etc)  which  could  be 
swallowed by small children. Please keep the thermometer and its batteries 
out of the reach of small children. If the battery or other parts are swallowed 
you should seek medical help immediately. 
♦  The  enclosed  batteries  may  not  be  recharged  or  reactivated  by  other 
methods,  may  not  be  dismantled,  thrown  into  fires  or  short-circuited. 
Batteries must be disposed of properly. Suitable methods for the disposal of 
batteries include returning them to the place of purchase or disposal in 
communal collection points. 
♦  Protect the SC 42 TM from direct sunshine and temperatures above 50°C. 
♦  Never drop the SC 42 TM, do not bend or open it (with the exception of the 
battery compartment for battery replacement). 
Operating manual: 
Press the 0/I button to switch on. A short signal tone shows that the device is in 
the "switched on" condition. A segment test takes place simultaneously (checks all 
display  segments  and  carries  out  an  internal  function  test  (see  under  "Function 
test")).

After this, if the temperature measured by the temperature sensor is less than 32°C, 
the display shows an "L“ and "°C“. After around one  second, the "°C“  starts to blink. 
The „L“ stands for low (less than 32°C). 
The  current  temperature  is  continuously  displayed  during  measurement,  and  the 
"°C"  blinks  during  the  entire  measurement  time.  The   measurement  is  completed 
after around 30 seconds. 
If the measurement is taken orally or rectally, the approximate final temperature is 
shown after about 30 seconds and  changes only marginally after this time. A 
measurement period  of  between five  and  10  minutes  must  be  observed  for  the 
underarm  measurement  method.  The  signal  tone can  be  sounded  several  times 
during this period. Since the contact between the temperature sensor and the armpit 
is not as good as those for oral and rectal measurements, the temperature rise is 
slower which causes this effect. 
After the measurement is completed,  the temperature value measured remains in 
the display until the SC 42 TM is switched off. To turn the device off after use, press 
the  0/I  button  briefly.  The  signal  tone  will  again  be  sounded.  If  the  device  is  not 
switched off, a signal tone is sounded after around 8 minutes and the device then 
switches off automatically. 
Display of last measured value: 
If you keep the 0/I button pressed for longer than three seconds, the last measured 
value will be shown in the display. As soon as you release the I/O button, the device 
is ready to take measurements.  
Function test: 
The  thermometer  is  checked  for  correct  functioning  automatically  every  time  it  is 
switched on. All segments  are displayed, and then L°C.  If a failure (measurement 
inaccuracy) is recognised, "ERR“ (Error) is shown in the display. 
Measured value deviation: 
The  measured  temperatures  will  always  deviate,  depending  on  the  measurement 
location. This is normal, and caused by deviations in temperature distribution on the 
human body. You could, for example, measure a rectal temperature of 36.6°C, an 
oral temperature of 36.1°C and an underarm value of  35.6°C. 
Fever alarm: 
If the  temperature  registers higher  than  37,5°C,  th e fever  alarm  (a  quick  beeping 
sound  which  occurs  continuously  for  about  8  seconds)  will  sound  when  the peak 
temperature has registered..

Measurement locations: 
In the mouth (oral) 
Small temperature variations in the mouth between measurements are normal. 
These are caused by varying temperature distribution within the mouth. Try to place 
the thermometer in one of the  two heat pockets under the tongue, to the left and 
right of the tongue root. The measurement sensor must have good contact with the 
tissue. The subject should close the mouth and breathe normally through the nose 
so that the measured result is not affected by breathed air. 
Measuring period: approx. 1 minute 
    Heat pockets 
In the anus (rectal) 
This is  the  safest  method.  It is particularly suitable for infants and small  children. 
Guide  the  thermometer  point  carefully  2  -  3  cm  into  the  anus.  Measuring  period: 
approx. 1 minute. 
Under the arm (axillary) 
From a medical viewpoint this type of measurement leads to inaccurate values. It is 
therefore unsuitable for carrying out exact measurements. 
Measuring period: 5 to 10 minutes. 
Measuring the basal body temperature 
The device can also be comfortably  and  practically used for the  measurement  of 
fertile  or unfertile  days  in the  female  cycle  using the  temperature  measurement 
method. 
Changing the battery:
As  soon  as  the    symbol  appears  in  the  display,  the  battery  has  run  out  and 
requires replacement. Always replace the discharged battery with one of the same 
type. To do this, proceed as follows:
