Service levels
There are two service levels which are both accessible by
passwords. To get into these levels and to release processes the
touch keys 1 ... 0 have to be pressed. For that purpose, the plus
and minus keys bear numbers which in the illustration below are
slightly bigger than in reality.
In order to get access to the service pages, two prerequisites
have to be ful

• there must not be any error message on the display
• there must not be any incoming signal from the coin/
token box system
In case there is an error message you need to reset this
message by touching the “Stop” sensor
fi eld.
