...the display is fading?
Usually the first sign of an expired battery is the fading of the digits when using the backlight or the low battery indicator
. Have the
batteries checked.
...the wrist unit battery needs to be changed?
We recommend that all service should be done by an authorized Polar Service Center. The 2-year International Guarantee does not cover
damage or consequential damage caused by service not authorized by Polar Electro. The Polar Service Center will test your wrist unit for water
resistance after battery replacement and makes a full periodic check of your complete Polar heart rate monitor.
...someone else starts using my wrist unit?
Each time the user changes, the new user should enter her or his user information settings first and then create a new Program. Changing the
user information or creating a new Program does not delete the saved data from the Daily, Weekly, and Totals Files.
...the buttons do not react?
Reset the wrist unit. Resetting clears the date and time settings.
Press all buttons except the Light button at the same time until the display is filled with digits. Press OK.
For further information, see the section Basic Settings. If you have already set the Basic Settings once, you
can skip them after setting the date by pressing and holding the Back button. If you do not press any button
after you reset the wrist unit, within one minute the wrist unit goes to the Time of Day display.
If this does not work, have the batteries checked.
...the Updated OwnZone limits vary a lot?
Heart rate variability reacts sensitively to all changes taking place in your body and environment. The OwnZone heart rate limits are affected
by, amongst other things, your state of fitness, the time of day of the OwnZone determination, the type of exercise and your state of mind.
The lower limit of the OwnZone can vary for the same person by 5-10 beats but as much as 30 beats is possible. However it is important
that the exercise carried out in the OwnZone feels light or moderate. For example, if you raise your heart rate too rapidly after the first stage,
you may receive OwnZone heart rate limits that are too high. If the OwnZone limits seem to be too high, we recommend that the OwnZone
determination be repeated.
