5 Current Repair
5.1 General Requirements
Digital system repair requires special training of technical staff, special equipment and
service software which you can receive from the manufacturer or the representative of
the company. The repair connected with the electronic unit opening is prohibited.
The repair of computer equipment and pattern-stimulator monitor can be conducted
by dedicated establishments for computer equipment service.
The current repair of the digital system includes the repair of some components and
cables. The repair of the components when connected to the digital system is prohib-
ited. During the current repair, all the digital units must be switched off.
5.2 EEG Cables, ECG Cables and Adapters
The cables are examined externally, and the circuit is checked for short circuit or
break. Shielded cables are also checked for short circuit between screen and cable,
and between cables. In case the cable is broken or grounded, it is necessary to re-
place or cut if the cable length is sufficient.
5.3 Computer Interface Cable (USB Cable)
The computer interface cable (Fig. 55) is examined externally, and the circuit is
checked for short circuit or break. In case of cable failure, it should be replaced or re-
paired by shortening the length. When replacing it is necessary to pay attention to ca-
ble marking. The use of the cable with other marking is prohibited.
