Notes:

 PAH8002EP can provide heart rate measurement. However, it is not for medical device usage.

 For usage of heart rate detection chip on the wearable device that to be put on the wrist, finger or palm,

 The chip must be placed securely and in-contact with the skin surface as well as keeping it stable without any motion

during measurement in acquiring accurate heart rate measurement.

 Do not wear the device on the wrist bone. It should be wear on the higher position of, especially for those with a

smaller wrist.

 Chip’s performance is optimized with good blood flow. It is recommended to have light exercise for a few minutes to

increase your blood flow before turning on the heart rate monitor.

 On cold weather condition or user is having poor blood circulation (e.g.: cold hands, fingers and feet), the chip

performance (heart rate accuracy) could be effected as the blood flow is slower in the measuring spot position. It is

recommended to activate the heart rate monitor in indoor use.

 If the chip is having problem to read heart rate, may try to swap it on the other side of hand wrist to repeat the

measurement.

 For continuous heart rate measurement, do minimize hand movement and extreme bending of the wrist.
