Care and Maintenance
To ensure proper function of your Heart Rate Watch:
• The watch buttons are not intended for use in or under water as this
will compromise the watch’s water resistance.
• Avoid rough usage or severe impacts to the watch.
• Keep the top ring sensor and the case back plate free from dirt, oils, or
other contaminants.
• Periodically clean the watch using a soft cloth with mild soap and
water, or similar cleaning solution.
• Keep the watch out of extreme heat or cold.
• Do not expose the watch to intense direct sunlight for long periods
of time.
• Do not expose the watch to chemicals such as gasoline, alcohol,
solvents, insect repellent or sunscreen.
Troubleshooting – Heart Rate
If you are having difficulty measuring your heart rate, you may want to try
the following steps. Try each of these in succession until you are able to
measure your heart rate:
1. Make sure the watch is snugly strapped to your wrist. A loose fit
makes it more difficult to properly measure your heart rate.
2. When touching the heart rate sensor, make sure you are using the
soft, flat pad of your finger, not the tip of your finger.
3. Press gently with enough pressure to activate the heart rate measure
function. Muscle “noise” from pressing too hard can make it difficult to
measure your heart rate.
