Page 7: Safety Instructions
Safety instructions Safety instructions Intended use This device amplifies electric audio frequency signals to operate passive speakers. Use the device only as described in this user manual. Any other use or use under other operating con‐ ditions is considered to be improper and may result in personal injury or property damage. No liability will be assumed for damages resulting from improper use. - Page 8 Safety instructions DANGER! Danger to life due to electric current! A short circuit could lead to a fire hazard and risk of death. Always use proper ready-made insulated triple-core mains cable with a safety plug. Do not modify the mains cable or the plug. In case of isolation damage, disconnect immediately the power supply and arrange repair.
- Page 9 Safety instructions NOTICE! Damage to the device due to high voltages! The device can be damaged if it is operated with the incorrect voltage or if high voltage peaks occur. In the worst case, excess vol‐ tages can also cause a risk of injury and fires. Make sure that the voltage specification on the device matches the local power grid before plugging in the device.
