WARNING
 
 
IMPORTANT SAFETY INSTRUCTIONS
 
 
The user of electrical products must be familiar with their potential dangers, and 
fundamental precautions must always be taken. Please read the following text 
carefully. 
 
Power supply units manufactured and supplied by Audio Developments Ltd are not 
user serviceable. There are no user-serviceable parts associated with any such 
power supply unit. 
 
THE OUTER COVERS MUST NOT BE REMOVED
 
Such a power supply unit is solely for use with audio mixers and sound processors - 
hereafter called the equipment - manufactured by Audio Developments Ltd. 
Always use a cord set accepted by a National Approved Body. 
 
EARTHING/GROUNDING: When using an external power supply unit that is 
connected to the mains supply to drive the mixer it must be CONNECTED TO 
EARTH. 
 
In certain types of malfunction or breakdown, earthing provides a path of least 
resistance for electric current and considerably reduces the risk of electric shock. 
 
DANGER: Incorrect connection of the equipment grounding/earthing conductor can 
result in the risk of electric shock. Where possible obtain a pre-wired mains lead from 
a reputable supplier with the correctly fitted mains connector for the type of mains 
outlet in use; otherwise, one correctly wired and checked by a qualified electrical 
engineer. If your mains lead is not suitable for the mains outlet, have the correct plug 
fitted by qualified personnel. 
 
The MAINS PLUG of this equipment is the primary disconnect device. Therefore, in 
the final application, ensure it remains close to the equipment and easily accessible.
