7. FREQUENTLY ASKED QUESTIONS

What should I do if...
...the data transfer from the wrist unit to my PC was unsuccessful?
Check that:
• the wrist unit is in the Connect mode.
• the wrist unit is in the correct position for the infrared window or
external device.
• the surroundings are not too bright. This problem often occurs near
windows or surfaces that reflect light.
• there are no obstructions between the infrared windows of the
interface and the wrist unit. For further information on data transfer
to a PC, see the separate Toolkit user manual.
...there are no reactions to any buttons?
If there are no reactions to any buttons, reset the wrist unit. Resetting only
clears the date and Daily Alarm times, not the recorded files or Auto Log.
The altimeter and barometer calibration values return to their default values
(standard sea level pressure 1013 hPa/29.90 inHg). To reset, press all
the buttons, except the Light button, simultaneously until the display is
filled with numbers and texts. To set the time and date again see page 10.
Note: If you do not press any button after you reset the wrist unit, within
one minute the wrist unit goes to the Time main mode.
...the heart rate reading becomes erratic or extremely high?
You may have come within range of strong electromagnetic signals, which
can cause erratic readings. This may occur near high voltage power lines,
traffic lights, overhead lines of electric railways or trams, skilifts, car motors,
bike computers, some motor driven exercise equipment (e.g., fitness testers)

or cellular phones. Check your surroundings and move further away from
the source of the disturbance.
...the altitude reading changes even though I stay at the same
altitude?
Altitude measurement is based on barometric pressure. Changes in
altitude or weather cause changes in the pressure. For example, if you
stay at the same altitude but the weather and pressure changes, the
altimeter interprets the pressure change as a change in altitude.
...the barometric pressure readings are inaccurate?
Your barometer may show faulty barometric pressures if it is exposed to
external interference like strong wind or air conditioning. It is also important
that you stay at the same altitude when using the barometer. If the readings
are constantly inaccurate, dirt may be blocking the air pressure channels.
In this case, send the Outdoor Computer to a Polar Service Center.
...I cannot calibrate the compass or the calibration of the compass
was unsuccessful?
Check that you:
• are not around a strong magnetic source.
• rotate 360° even if the indicators do not appear during calibration.
• do not tilt the compass, keep it horizontal during calibration.
• do not leave empty spaces between the
