Handling; Maintenance - Conrad MPA-M.A.R.L.I.S. MkIII Notice D'emploi

12. Handling

• Never connect the mains plug to a mains socket immediately after the system was taken from a cold to a warm
environment. The condensation generated may destroy the system.
Allow the system to reach room temperature before connecting it. Wait until the condensation has evaporated.
• Never pull the mains plug from the mains socket by the cable. Only pull it from the mains socket by the intended
grip areas.
• Unplug the mains plug from the mains socket if you do not use the device for an extended period of time.
• Disconnect the mains plugs from the mains socket in thunderstorms for reasons of safety.
• Do not listen to excessively loud music over an extended period of time. This may damage your hearing.

13. Maintenance

Periodically check the technical safety of the PA system, e.g. check for damage to the mains cable(s) or the casing(s).
If it can be assumed that safe operation is no longer possible, the system must be turned off and precautions are to
be taken to ensure that it is not used unintentionally. Pull the mains plug from the mains socket!
It can be assumed that safe operation is no longer possible if:
• there is visible damage to the system or to the mains cable
• the system no longer works
• the device was stored under unfavourable conditions for an extended period of time or
• after exposure to extraordinary stress caused by transport
