What are the safety precautions I should follow when using the Marshall DSL40CR?

Always connect the amplifier to a grounded power outlet, ensure proper ventilation to prevent overheating, and do not expose it to rain or moisture. Disconnect power before cleaning or moving the amplifier, avoid placing it near heat sources or in direct sunlight, and use caution with volume levels as high volumes can cause permanent hearing damage. Do not attempt to service the amplifier yourself—refer all servicing to qualified service personnel.
