Configuration
For configuration of the device press "Set"-key (key 4) for 2 seconds.
Choose between the individual values that can be set by pressing the "Set"-key (key 4) again.
The individual values are changed by pressing the keys "
5
" (key 2) or "
6
" (key 5).
Use key "Store" (key 6) to leave configuration and to store settings.
