the chest belt with the watch once. Select any
training and press the Navigation button
k ENTER.
The synchronization starts automatically and
takes just a few seconds.
After successful synchronization your ONYX FIT
gives a short confirmation with "Sync ok".
Note: If you do not see this indication on your
watch synchronization has already been
completed successfully.
After your ONYX FIT has successfully synchro-
nized with your chest belt you can start training
by pressing k START.
Note: please refer to Chapter 7.4 "Trouble-
shooting" for possible problems with synchro-
nization.
