Product Name
Portable Medical Home LED Screen Clear Reading Fingertip Pulse
Oximeter
Feature
ACCURATE, FAST AND RELIABLE - the CMS 50 DL Fingertip Pulse Oximeter accurately determines
your SpO2 in less than 8 seconds
SPORT/HEALTH ENTHUSIASTS - For aviators, sporting enthusiasts, skiers, bikers, or high
altitude climbing, the CMS 50 DL is a RELIABLE companion for quick
and easy readings for oxygen saturation
THE ORIGINAL STANDARD - Setting the original standard for reliable and consistent pulse
oximetry, the CMS 50 DL is backed by an ironclad 12-month warranty
PACKED WITH ACCESSORIES - Includes 2X AAA batteries that enable use out of the box, a
pulse oximeter case to protect the device when not in use, and a
LANYARD for convenience as either a wrist strap or to be worn
around the neck
DESIGNED For Sports and Aviation Enthusiasts and can be used as a heart
rate monitor
How to ensure the accuracy of your measurement?
1, Moving too fast will affect the accuracy; try to stay still
while waiting for your reading.
2, When the oxygen saturator and the heart are at the same level,
the measurement results are optimal.
3, Avoid nail polish or long nails on the finger used for the
reading. Fingers should not be wet at all either.
4, Ring finger, middle finger and index finger are recommended as
suitable monitor position

1) Display Format: OLED Display;
SpO2 Measuring Range: 0%- 100%;
Pulse Rate Measuring Range: 30 bpm - 250 bpm;
Pulse Wave Display: columniation display and the waveform display.
2) Power Requirements: 2 x1.5V AAA alkaline battery(or using the
rechargeable battery instead), adaptable range: 2.6V~3.6V.
3) Power Consumption: Smaller than 30mA.
4) Resolution: 1% for SpO2 and 1 bpm for Pulse Rate.
5) Measurement Accuracy: ±2% in stage of 70%-100% SpO2 , and
meaningless when stage being smaller than 70%.±2 bpm or±2%

Troubleshooting
| Trouble | Possible Reason | Solution |
The SpO2 and Pulse Rate can not be displayed normally
| 1. The finger is not properly positioned. 2. The patient's SpO2 is too low to be detected.
| 1. Place the finger properly and try again. 2. Try again; Go to a hospital for a diagnosis if you are sure the
device works all right. |
The SpO2 and Pulse Rate are not displayed stably
| 1. The finger is not placed inside deep enough. 2. The finger is shaking or the patient is moving. | 1. Place the finger properly and try again. 2. Let the patient keep calm
|
The device can not be turned on
| 1. The batteries are drained or almost drained. 2. The batteries are not inserted properly. 3. The malfunction of the device. | 1. Change batteries. 2. Reinstall batteries. 3. Please contact the local service center.
|
The display is off suddenly
| 1. The device will power off automatically when it gets no signal within 5 seconds. 2. The batteries are almost drained. | 1. Normal. 2. Change batteries.
