battery compartment properly in the right direction.
3. Replace the cover.
Remark:
After finishing battery installation, the oximeter will
automatically power on and display software version
number firstly.
In order to record data in real time in future, please set the

probe receptacle properly.
Figure 5 Sp02Probe Connection
2. Fix the oximeter on your left wrist as shown in Figure 6
(Refer to Appendix for details);
3. Then, hold the probe with its opening towards your
index finger. The probe should be oriented in such a way
that the sensor side with a finger tip sign is positioned on
the top (Figure 6).

3. Next, insert your index finger into the probe until the
fingernail tip rests against the stop at the end of the probe
(Figure 7). Adjust the finger to be placed evenly on the
middle base of the sensor (make sure the finger is in the
right position). If the index finger cannot be positioned
correctly, or is not available, other finger can be used.

5. Prompt Information
During monitoring, if there is no signal to be detected, the
short lines will be prompted on the screen instead of the
numerical values, as shown in Figure 10.
Figure 10 No Signal
During measuring, the measured values are recorded every
2 seconds. The length of data record is limited to 30
seconds at least, and the maximal length for one record is
also limited to 2 hours.
During measuring, if the memory is full or the total
number of the records is 256 pieces, the earliest records
will be overwritten and the icon “ ” will appear on the
screen for prompt, as shown in Figure 11.

Note: It is suggested that the data shall be uploaded
to computer for saving, or the earliest records will be
overwritten.
6. Working Mode
yThe measurement will start automatically when the
finger is inserted into the soft rubber of the sensor, so
the data recording (SpO2and PR values) starts
simultaneously as well. The display is as shown in
Figure 9.
yDuring measuring, long time press“▲” key to blank
the screen (the measurement and data recording are
still undergoing.), but long time pressing any key
will activate the display for viewing the current

yIf there is no signal to be detected (e.g. finger off) for
20 seconds, the device will be at idle state (i.e. blank
screen and standby for measurement).
yWhen the device is at idle state, long time pressing
any key will activate the LCD display, or once the
finger is inserted in the soft rubber of the sensor, the
measurement will start and LCD display will be
activated as well.

3.3 Upload Data
Before uploading the data to PC, please quit from the menu
screen if you are doing the setup. When start uploading,
connect the data cable between the device and PC, then do
the following operation by the instruction in “Oximeter
