2. Getting Started
Before Use
The Checkme Pod supports real-time monitoring the oxygen saturation
(SpO2), P ulse Rate (PR), Perfusion Index(PI) and body temperature by
external SpO2 probe and temperature probe.
Power On/Off
Press the Home button to power on the device.
Press and hold Home button for 2 seconds to power off thedevice.
Prior to Measure
Before me asure, pay attention to the following points in order to
obtain precise measurements.

The finger inserted in SpO2sensor must be clean.
 Any of the following conditions may cause inaccurate
measurements of oxygen saturation (SpO2), P ulse Rate (PR)
and Perfusion Index(PI) , including but not limited to:
- Flickering or very bright light;
- Poor blood circulation;
- Low hemoglobin;
- Hypotension, severe vasoconstriction, severe anemia or
hypothermia;
- Nail polish, artificial nails;
- Any tests recently performed on you that required an
injection of intravascular dyes.

If blood circulation is poor, SpO2, PR, and PI may not be
measured. Rub your finger to increase circulation, or place
the SpO2 sensor on another finger.

The device measures oxygen saturation of functional
hemoglobin. High levels of dysfunctional hemoglobin (caused
by sickle cell anemia, carbon monoxide, etc.) could affect the
accuracy of the measurements.
 The pleth waveform displayed on the device is normalized.

Please keep the temperature probe close to the skin when
measuring. If it is loose, the temperature measurement result

7
could be inaccurate.
 Before measuring the temperature, make sure that the skin
that is in contact with the temperature probe is flat and
wrinkle-free.
