Device description and intended use 
This  digital  thermometer  is  intended  to  measure  human  body  temperature  for 
children and adults; it  has digital display and be used in household environment. 
Contraindications 
The digital thermometer is contraindicated: 
1.  Place the  thermometer probe in  scarred tissue  or tissue  compromised by 
any disorders of
measuring site. 
2.  Place the thermometer probe on  skin exposed to direct sunlight, fireplace 
heat, cold compress  therapies, air conditioner flow, etc. 
Features 
1.  Easy to read digital LCD (liquid crystal display). 
2.  Quick  measurement,  the  minimum  measuring  time  of  oral  and  rectal  is 
around 10 seconds with  proper use. 
3.  Memory display for last temperature taken. 
4.  Compact, accurate and durable LSI (large scale integration) device. 
5.  Very sensitive to obtain temperature. 
6.  If the thermometer is inadvertently left on after temperature stabilization, it 
will automatically shut  off in 30 seconds. 
7.  Small light weight unit. 
8.  The unit is water resistant 
Precaution 
1.  Do not boil the probe.  Instead, clean the unit by  wiping  it  with a dry cloth 
and  disinfect  the  probe  with  isopropyl  (rubbing)  alcohol.  See  cleaning 
instructions for details. 
2.  Do not drop the thermometer or expose it to heavy shock. 
3.  Do not bite or swallow the probe and the battery cover. 
4.  Do  not  let  thermometer  come  into  contact  with  any  thinner  or  chemical 
solvents 
5.  Do not  store the unit under direct sunlight, at a high temperature, in  high 
humidity or dust.
Performance may be degraded. 
6.  Stop  using  the  thermometer  if  it  operates  erratically  or  if  the  display 
malfunctions. 
7.  Keep out  of  reach of  unsupervised  children. Do  not  let  children play with 
the unit. Temperature should be taken under adult supervision. 
8.  Components  may  be  harmful  if  swallowed.  Contact  a  physician 
immediately should this occur.   
9.  Clean the thermometer probe before storing. 
10.  Do not attempt to disassemble the unit except to replace the battery.
11.  Do not use if the display malfunctions or it operates irregularly. 
12.  Do not put this unit in dishwasher. 
13.  If the thermometer has been stored at below-freezing temperatures, allow 
the thermometer to
warm naturally to room temperature before using. 
14.  Performance of the thermometer may be degraded  if:  Operated  or stored 
outside  stated  temperature  and  humidity  ranges  or  if  the  patient's 
temperature is below the ambient (room)  temperature. 
15.  Before using, it is recommended to no drinking, smoking or excising for at 
least twenty minutes  prior to do a measurement and no talk,  walk during 
measuring, it may cause inaccurate reading. 
16.  Only use the thermometer indoors. 
17.  When the battery is almost exhausted, the symbol “   ” will appear in 
the display window,  meaning it’s time to discard. 
18.  The reading is  for reference, if feel  sick  or uncomfortable,  please contact 
the physician.   
19.  The  thermometer  is  a  direct  mode  thermometer.  Measuring  site  is 
reference body site and the  measuring site is oral and rectal. 
Device description 
How to use 
1.  Press and release the ON/OFF button, the display read all segments and 
confirming that the unit is  functioning properly. 
2.  Then the display will show L°C with °C flashing. If the room temperature is 
greater than 32.0°C,  it will display rather than L°C. 
3.  Place the probe in the appropriate position. 
4.  Once the degree sign °C stops flashing, the measurement is finished and 
the  temperature  is  displayed.  An  alarm  signal  will  also  sound  for 
approximately 5 seconds after °C stops flashing. 
5.  The  unit  will  automatically  turn  off  in  30  seconds  (approx.).  However,  to 
prolong battery life, it is  best to press the ON/OFF button to turn off once 
the temperature has been indicated. 
Last-Temperature Memory Recall: 
When  the  ON/OFF  button  is  depressed  to  activate  the  thermom-  eter,  hold 
down  for  approximately  5  seconds.  The  display  of  188.8  will  change  to  show 
the last  reading. This reading is displayed as long as the button is held down. 
When  the  button  is  released,  the  thermometer  will  be  in  “ready-to-measure” 
mode and the recalled temperature will be erased. 
Fever alarm: 
If  the  temperature  registers  higher  than  37.5°C,  the  fever  alarm  (a  quick 
beeping sound which occurs continuously for about 8 seconds) will sound when 
the peak  temperature has registered. Also, the result will keep flashing until the 
thermometer is turned off. 
Backlight: 
Reliable method to measure temperature 
BODY TEMPERATURE: 
A  person’s  body temperature  will  usually be  several  tenths  to  one  full  degree 
lower  in  the  morning  than  it  is  in  the  late  afternoon.  Therefore,  if  your 
temperature  is  36.6°C  in  the  morning,  it  could  be  36.9°C  or  more  in  the  late 
afternoon and still be normal. To determine what  your normal body temperature 
is  you should take your temperature  both  in  the  early morning and  in  the late 
afternoon over several days. Children have the
same normal temperature range 
as  do  adults.  A  fever  for  both  children  and  adults  is  typically  defined  as  a 
temperature  over 37.5°C.  Exercise,  excessive clothing, hot  bath,  hot  weather, 
warm food and  drink can cause  mild  elevations of  up  to
38.0°C to  38.4°C .  If 
you suspect one of these to be the cause of an elevated reading, eliminate the 
possible cause and retake the temperature in a half hour. 
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. 10 seconds
