optional, the default is “Spot check”.
Spot check mode: the measuring time lasts 30 seconds with a
counting-down indication. The SpO2 and PR readings will freeze at
the end of 30 seconds, the analysis result for the pulse rhythm will
be displayed on the screen as well.
Continuous mode: measurement will start automatically when
finger is inserted into the oximeter, SpO2 and PR readings will be
displayed until the finger is removed from the oximeter.
6 Record List
A single group of stable readings will be recorded in the record list
each time when the oximeter shuts down regardless of spot-check
or continuous mode. However, if the time from displaying valid
readings to the end of measurement is less than 5 seconds, then no
recording will be done.
Up to 12 groups of records can be stored in the record list, the
newest record is marked as M1, and the oldest record is marked as
M12. The new record will override the previous record.
When batteries are removed from the device all readings will be
deleted.
On power off status, long pressing the Display key shows the record
list screen. On record list screen, a short pressing on the Display key
can shift the records display, and if there is no key operation for 6
seconds, then the oximeter will power off automatically again.

8 Maintenance and Cleaning&Disinfection
8.1 Maintenance
The expected service life (not a warranty) of this device is 5 years. In
order to ensure its long service life, please pay attention to the
maintenance.
Please change the batteries when the low-voltage indicator lightens.
Please clean the surface of the device before using, with 75% alcohol
wipes, then let it air dry or wipe it dry. Do not allow liquid to enter
the device.
Please take out the batteries if the Oximeter will not be used any
more than 7 days.
The recommended storage environment of the device:
ambient temperature: -20 ºC - 60 ºC, relative humidity 10% - 95%,
atmospheric pressure: 50 kPa - 107.4 kPa.
The Oximeter is calibrated in the factory before sale, so there is no
need to calibrate it during its life cycle. Any SpO2 simulators should
not be used to validate the accuracy of the Oximeter, they can only
be used as functional testers to verify its precision. The SpO2
accuracy claimed in this manual is supported by the clinical study
conducted by inducing hypoxia on healthy, non-smoking, light-to-
dark skinned subjects in an independent research laboratory.
Caution:
High-pressure sterilization cannot be used on the device.
Do not immerse the device in liquid.
It is recommended that the device should be kept in a dry
environment. Humidity may reduce the life of the device, or
even damage it.
8.2 Cleaning and Disinfecting Instruction
Surface-clean sensor with a soft cloth damped with a solution such
as 75% isopropyl alcohol, if low-level disinfection is required, use a
mild bleach solution.
Then surface-clean with a cloth damped ONLY with clean water and
dry with a clean, soft cloth.
Caution:
Do not sterilize by irradiation steam, or ethylene oxide.
Do not use the Oximeter if it is damaged.
