Cleaning and disinfection
Troubleshooting
Specification 
1.  Please clean the  surface  of  the device  before 
using. Wipe  the  device  with  medical  alcohol 
(70% isopropyl alcohol)first, and then let it dry 
in air or clean it by dry clean fabric. When clean-
ing the device with water, the water tempera-
ture should be lower than 60ºC
2.  Using the medical alcohol to disinfect the prod-
uct after use, prevent from cross infection for 
next time use.
3.  The  best  storage  environment  of  the  device 
is - 20ºC to 70ºC ambient temperature and not 
higher than 95% relative humidity. 
4.  Users are advised to calibrate the device termly 
(or  according  to  the  calibrating  program  of 
hospital). It also can be performed at the state-
appointed agent or just contact us for calibra-
tion.

Note:  1.  Do not sterilize, autoclave or immerse this 
device in liquid. Do not pour or spray any 
liquids onto the device.
            2.  Do  not  use  caustic  or  abrasive  cleaning 
agents, or any cleaning agent containing 
ammonium chloride or isopropyl alcohol.
-  A functional tester cannot be used to access the 
accuracy of a pulse oximeter monitor.
-  Do  not  self-diagnose  or  self-medicate  on  the 
basis of the measurements without consulting 
your  doctor.  In  particular,  do  not  start  taking 
any new medication or change the type and/or 
dosage of any existing medication without prior 
approval.
-  Do not look directly inside the housing during 
the measurement. The red light and the invisible 
infra-red light in the pulse oximeter are harmful 
to your eyes.
-  This  device  is  not  intended  for  use  by  people 
(including children) with restricted physical, sen-
sory or mental skills or a lack of experience and/
or a  lack of knowledge, unless they are super-
vised by a person who has responsibility for their 
safety or they receive instructions from this per-
son on how to use the device. Children should 
be supervised around the device to ensure they 
do not play with it.
-  Neither of the displays for the pulse wave and 
pulse  bar  allows  the  strength  of  the  pulse  or 
circulation to be evaluated at the measurement 
site. Rather, they are exclusively used to display 
the current signal variation at the measurement 
site  and do  not  enable reliable diagnostics  for 
the pulse.

EMC guidance and manufacturer’s declaration
Recommended separation distances between portable and mobile RF communications equipment and the ME equipment
The Finger-tip pulse oximeter is intended for use in an electromagnetic environment in which radiated RF disturbances are 
controlled. The customer or the user of the Finger-tip pulse oximeter can help prevent electromagnetic interference by main-
taining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Finger-tip 
pulse oximeter as recommended below, according to the maximum output power of the communications equipment.
