7.4 FAQ
What happens if I remove the chest belt
during training?
The watch will no longer display a signal, the
screen will indicate "0" – after a short period
of time the ONYX PRO goes into sleep mode.
Do SIGMA heart rate monitors switch off
completely?
No – in sleep mode only the time and date are
displayed so you can use the heart rate monitor
as a normal watch. In this state the ONYX
PRO uses only very little power.
Why does the display react slowly or is
colored black?
The operating temperature may be too high
or low. Your heart rate monitor is designed
for temperatures between 0°C and 55 °C
(32 - 131 degrees F).
What should I do if the screen display is
weak?
A weak display may be due to weak batteries.
You should change them as quickly as possible
– battery type CR 2032 (Item No. 00342)
