For other frequently asked questions please see:

• MIO Products FAQs

• Make sure the back of the MIO watch has good firm contact against your skin by fastening it securely. If you have a slender wrist please move the watch up away from your wrist bone.
• Press the sensors with your finger pads. Too much pressure will create too much muscle noise, which makes it hard for the watch to read your ECG signal. Please note that only the bottom sensor on the watch face will depress. The top sensor does not depress, so simply rest your finger against the top sensor while gently depressing the bottom sensor.
• If you are pressing the sensors correctly the screen will change and display a flashing heart icon and will read “BPM”. Press gently and hold until you see this screen. Keep holding the sensors for a few seconds until you get a heart rate reading.
• If you are holding an item in your hand or hanging a heavy item such as gym bag from your arms, this may interfere with MIO’s ability to read your heart rate.
• Keep your arm low, relaxed and close to your body. If you raise your arm above your heart this will slow down the heart rate function as your signal will be traveling against gravity. If you are moving while taking your heart rate, try to keep you fingers as steady on the sensors as possible.
• Try moistening your fingers and the back sensor of the face. It is okay to allow perspiration to build up against the watch; in fact this will likely allow MIO to read your heart rate more quickly. If your skin is dry this will affect the speed of the heart rate readings.
• If you are still unsuccessful after following these tips, please contact our customer service team at 1-877-566-4636 or by email at customerservice@miowatch.com for further assistance.

• Step One: Press the LIGHT button (top left hand side of the watch.) Check to see if the screen is illuminated. Cover the face of the watch or test in a dark area as the backlight may not be easily visible in well-lit environments.
• Step Two: If the backlight does not go on by following step one, press and hold the STOP button (bottom right hand side of the watch.) The display on the watch’s face will read HOLD and the watch will beep (takes approx. 2 seconds.) This will activate the light function on some MIO models (not applicable to all.) Then repeat step one to use the light.
• If your light still does not work please contact customer service at 1-877-566-4636 or by email at customerservice@miowatch.com

• If it takes a longer period of time to get a heart rate reading than you have become accustomed to.
• If the display on your MIO is blank.
• If the display on your watch is frozen on a particular screen and does not change.
• If your watch emits a constant loud beep.

5. How do I replace a dead battery?
We recommend that you take your MIO to a trusted jeweler or watch repairperson to change the battery. Fast Fix Jewelery and Watch Repairs is an authorized MIO battery change center and has been trained on how to properly replace a MIO Watch battery. However, if there is not a Fast Fix location in your area, please take your watch to a trusted jeweler or watch repairperson.

To locate a Fast Fix near you click here.

The jeweler/repairperson will first test to ensure your battery is indeed dead. The battery in a MIO should last up to one year from date of manufacture, however this may vary according to usage. Frequent use of the light and/or stopwatch/chronograph will significantly reduce the battery life. Please see the link below that clearly illustrates how to change and replace MIO’s battery. MIO uses a standard watch battery (CR2032.) Please print these instructions or take the instructions included in the MIO user guide with you to a trusted jeweler or watch repairperson. If you do not have access to a printer please contact customer service at 1-877-566-4636 or by email at customerservice@miowatch.com and we can arrange to have these instructions faxed to you (US and Canada only.)

*Please note that whether you bring your watch to Fast Fix or any another location, you should remind the jeweler that MIO is a water resistant watch and needs to be resealed and tested for water resistance post battery change.

For the LAP function to operate, start the chronograph/stopwatch feature. Do this by changing the mode (using the MODE button) until you reach the stopwatch/chronograph. Press the SET/START button to activate the stopwatch. The LAP function only operates to show periods of elapsed time. It does not serve to store or save lap times. The LAP function will show you how much time has elapsed since you pressed the LAP button, allowing you to time a lap. To calculate the lap time, press the MODE/LAP button (top right) while the stopwatch is running. Make a mental note of the time value shown on the display. When LAP is pressed, the time on the clock is stopped on the display, but the stopwatch/chrono continues to run. When LAP is pressed again, the stopwatch/chrono display will return back to the total time that has elapsed since the chronograph was started. Subtract that time value from the value when LAP is pressed and this will tell you your lap time.

To stop the LAP display on the face of the watch, press the MODE/LAP button. Press STOP to stop the chronograph.

9. I can’t seem to find the birth date screen. How do I access this screen?
Since your birth date does not change and you only need to set it once, the birth date is stored behind the date/calendar screen. However, you may access this screen after setting it initially if you want to make a change. To access the birth date screen from the time screen, press the MODE/LAP button once to go to the date/calendar screen. Press the SET/START button and hold it until the word ‘HOLD’ appears on the screen and the watch beeps once. Scroll through the date screen by pressing the SET/START button once for each digit until the day of the week is flashing. Press the SET/START button one more time: the entire display will change to the birthday mode and the year of birth will be flashing. Set this as you would the calendar and the watch will store and save your birth date and use this to calculate your age. You will see a gender icon flash in the top right hand corner of the screen, select the male or female and press the SET/START button.

7. How do I clear the “calories in” display on the MIO Shape, Shape Select and Shape Select Petite?
On your MIO Shape, Shape Select and Shape Select Petite, press the MODE button two times to get the “Cal IN” screen. Press and hold the SET/START button until ‘HOLD’ appears on the screen. Keep holding until the watch beeps once and then beeps once again (total of two beeps) then release the button. The display should read 0000.
The calorie in value does not clear itself. You must manually clear the value whenever you want to reset it back to 0 calories in.
