ORDINARY AND PERIODICAL MAINTENANCE
6.5.1 RESTRICTIONS:
WARNING: note that the TOUCH ME cash register only allows first level assistance
(replacing entire units such as electronic cards and/or the printing mechanism).
With the exception of the Battery, Fuses, and sub-parts of the keyboard, any interventions
that require the replacement of parts on the electronic cards or the printer are strictly
forbidden. All spare parts used during assistance operations must be original. The fuses
must respect the characteristics and the value indicated where they are mounted or on the
electrical layouts.
- Technical assistance operations must be limited to the replacement with original spare
parts.
- The device may in no way be modified by technical assistance operations: any part that
is replaced or removed due to technical assistance must be reconnected and mounted in
its original position.
6.5.2 REPLACING FUSES
The device contains a fuse that can be accessed only by authorized service personnel
(RCH technicians). Replacing this fuse requires the use of an automatic un-welding device
and a tin welder since the fuse is welded directly to the printed circuit.
