Maintenance - MC Crypt PPA8 Mobile Bedienungsanleitung

Maintenance

Check the technical safety of the mobile PA system regularly, e.g. check for damage to the power cable or to the
housing.
If you have reason to believe that the device can no longer be operated safely, disconnect it immediately and make
sure it is not unintentionally operated. Switch off the mobile PA system and disconnect from the mains supply.
It can be assumed that safe operation is no longer possible if:
• the device shows visible damage
• the device no longer functions
• the device has been stored for a long time under unfavourable conditions or
• after exposure to extraordinary stress caused by transport
You must observe the following safety instructions before cleaning or servicing the mobile PA system:
Live components may be exposed if covers are opened or components are removed.
The device must be disconnected from all power sources before any servicing or repair work
is carried out.
Capacitors inside the device may still carry voltage even though they have been disconnected
from all power sources.
Only qualified experts familiar with the hazards involved and the relevant regulations may
perform repairs.
Replacing the Fuse
If you have to replace the fuse, ensure that you only use fuses of the specified type and rated current (see „Technical
Data").
Never repair fuses or bridge the fuse holder.
• After disconnecting the device from the mains supply (pull the power plug and disconnect the mains cable from
the device!), use a suitable screwdriver to carefully lever out the fuse holder with the defective fuse at the POWER
INPUT (7) mains socket.
• Remove the defective fuse and replace it with a fuse of the same type.
• Carefully put the fuse holder with the new fuse back into its holder at the POWER INPUT (7) mains socket.
• Only then may you reconnect the device to the mains and put it into operation again.
