•  Do not connect the inputs / outputs of amplifiers or consoles 

to any other voltage source, such as a battery, mains source, or 
power supply, regardless of whether the amplifier or console is 
turned on or off. 

•  Power down & disconnect units from mains voltage before 

making connections. 

•  Do not use the unit near stoves, heat registers, radiators, or 

other heat producing devices.

•  Do not operate equipment on a surface or in an environment 

which may distort the normal flow of air around the unit. If the 
unit is used in an extremely dusty or smoky environment, the 
unit should be periodically “blown free” of dust. 

•  Do not remove the cover. Removing the cover will expose you 

to potentially dangerous voltages.

•  Do not drive the inputs with a signal level higher than that 

required to drive equipment to full output.

•  Do not run the output of any amplifier back into another input. 

•  In case of mal-function this device should be serviced by 

qualified service personnel only. 

•  The apparatus may not be exposed to dripping or splashing and 

no objects filled with liquids may be placed on the apparatus. 

•  The appliance coupler has to be readily operable to disconnect 

the device.
