Figure 4 Battery Installation
1. Lift up the cloth covered on the battery cover. Then, use
your index finger and middle finger to press against the
battery cover. Meanwhile, slide it towards the side with
SpO2probe (as shown in Figure 4).
2. Refer to Figure 4, insert two AAA size batteries into the
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.

6. Prompt information
During monitoring, if you haven’t inserted your
finger into the probe, “Finger out ” will be prompted
on the screen.
During monitoring, if the probe is not connected to

Figure 10 No Signal
During measuring, if the memory is full or the total
number of the records is 1024 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.
Working Mode
The 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 9A
During measuring, if the display mode is not display
always on (the symbol for “display always on” is not
shown on screen) and no key button operation for 1
minute, the LCD display will be blank for power
saving even when the measurement and data
recording are still undergoing, but long time pressing

any key will activate the display for viewing the
current measuring information again.
If 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).
When the device is at idle state, long time pressing
any key will activate the LCD display for measuring
default screen, 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.
Note: During measuring, there is a green-dot
flashing on the screen for indicating the
measurement and data recording are undergoing
when the display screen is blank, and if SpO2
or/and PR values exceed the preset limit, it will
active the display and the value exceeded limit
will flash.
