Operation and Service KBL 4000/4500
The operating hours of the tubes are set by pressing the 4 and
9 keys on service level II. After leaving either the menu or the
service level, the frequency is switched off.
There are two service levels which are both accessible by pass-
words. 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 ser-
vice pages, two prerequisites have to be fulfi lled
— there must not be any error messages 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 mes-
sage by touching the „Stop“ sensor fi eld.
