 Other Operating Considerations

 Operating range is 32ºF to 104ºF (0ºC to 40ºC), 15 to 93% relative
humidity.

 Maximum operating altitude is 2000m.

 Maximum expected service life is 5 years.

 Storage and transport range is -4ºF to 158ºF (-20ºC to 70ºC), 0 to 93%
relative humidity.

 To keep the life of your electronic stethoscope, please avoid operating
under extremely hot and extremely cold condition.

 Don’s use solvents and oils to prevent unexpected hazards.

 Remove the battery if the electronic stethoscope will not be used for
several months.

 Failure to follow care and maintenance recommendations could result in
damage to the internal components of the Electronic Stethoscope DS101.
Internal damage could cause malfunction of the product, ranging from a
slight decrease in auditory response to complete failure of the product.
NOTICE ：If you experience any problems with the Electronic
Stethoscope DS101, do not attempt to repair it yourself. Please notify our
customer service center for directions on shipping and receiving.

1) Before start to cleaning, please check the tubbing connector and all
structure of stethoscope are stable to avoid liquid infiltration.
NOTICE ： To clean the chestpiece, you may take off the diaphragm for the
sterilizing process.
1) Avoid directly wiping up with alcohol or detergent solution in case of
the unnecessary damage, spray 70%~75% alcohol solution on the
dry, clean tissue paper or cotton sheet that we highly recommended.
2) Wipe the electronic stethoscope.
3) After wiping out the dust and dirt, please check the electronic
stethoscope is working as usual.

 Ear tubing and ear-tips: It can be wiped clean with alcohol. Ear-tips may
be removed for the advanced cleaning and disinfection.
Diaphragm: you can wipe the diaphragm with 70%~75% alcohol
solution on the dry, clean tissue paper or cotton sheet that we highly
recommended. Otherwise, replace the new diaphragms after the device
is dirty or used in high contamination patient.
WARNING: To reduce the risk of infection, cleaning of stethoscope
should be done between each patient use.
WARNING: Do not immerse the stethoscope in a liquid or subject it
to any sterilization process. The device might be damaged.
12. Warranty
Your Electronic Stethoscope is warranted against any defects in material and
manufacture for a period of one year. If a material or manufacturing defect is
discovered during the warranty period, repairs will be made without charge
upon the return of the instrument to vendor, except in cases of obvious abuse
or accidental damage.

To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the DS101 is used exceeds the applicable RF

For some services, only the uplink frequencies are included.
The carrier shall be modulated using a 50 % duty cycle square wave signal.
As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does
not represent actual modulation, it would be worst case.
