7 HEARTBEAT MEASUREMENT
7.1 IMPORTANT NOTES
1. A sensor contact located on the back of the watch must make firm
contact with the user's skin during measurement.
2. DO NOT take measurement when diving or under water.
3. Clean the back cover occasionally by applying a few drops of water
and then wipe it with a paper towel thoroughly to remove any residual
grease.
4. DO NOT use hand cream, it will insulate the signal between the skin
and the sensors. Rub the skin and the fingers with soap and water
occasionally for better signal transmission.
5. DO NOT use the finger tips where the skin is dry and thick. For those
with extremely dry skin, moisten fingers and wrist with tap water.
6. Hold the watch firmly while taking a measurement in motion, this
assists the sensors in making firm contact with the skin and fingers.
7. During the measurement, avoid any abrupt motion. It will create unde-
sired noise, hence an error heart beat reading may result.
