Troubleshooting
The distance measurements are very imprecise 
The watch uses the step length measured during calibration to estimate the 
traveled distance. 
Recalibrate the step counter. Calibrate it for walking and for running and use extra 
care during the calibration. 
Running on uneven surfaces may also result in bad calibration. 
 
The heart rate is not shown or is shown incorrectly 
Make sure the chest belt is positioned correctly and fits well 
Your skin should not be too dry or too cold. 
The contact areas can be slightly moistened to improve function 
Electromagnetic interference may have an adverse effect on reception 
The distance between watch and chest belt must be under 60cm 
Other heart rate measuring devices within a 2m range may also cause 
interference. 
Wireless bicycle computers may cause interference 
The batteries may be low and require replacing 
 
The display is unreadable / the light does not work 
Replace the batteries 
Replacing the watch battery
The battery replacement can be performed by a watch maker in addition to a 
water resistance test. To replace the battery yourself, please read the following 
instructions first: 
Remove the screws (1, 2, 3 and 4) from the back side of the watch with a small 
Phillips screwdriver. Remove the caseback and the battery sticker. Use a small, flat 
tool to open the latch (5) of the battery holder. Remove the battery and insert a 
fresh 3V CR2032 battery with the (+) terminal facing upwards. Ensure that the 
gasket (6) is seated correctly. Close the latch of the battery holder. Replace the 
battery sticker and the caseback and replace the screws.

Battery low indicator
If the battery voltage on the chest belt battery drops below the voltage required for 
normal operation, "TXGURT/TXBELT" and "LO BAT/BATT" will appear on the 
display. Replace the battery of the chest belt as described in the chapter "Chest 
belt".
Water resistance
Water resistant up to 3 bar. The bar value specifies the atmospheric overpressure 
which is applied during testing (DIN 8310). 
 
Water resistance of the chest belt
Water resistance according to IEC 60529 IPx7: 30m
