SAFETY PRECAUTIONS 

                                                   

                                              

 

PLEASE READ BEFORE INSTALLING

 

 

 

WARNING: to prevent fire or shock hazard, do not expose this unit to rain or moisture. Care should be 
taken to prevent objects or liquid from entering the enclosure. Never handle the power cord with wet 
hands. 

 

  The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user of the 

presence of uninsulated “dangerous voltage” within the product’s enclosure that may constitute a risk of 
electric shock to you. 

 

  The exclamation point within an equilateral triangle is intended to alert the user of the presence of 

important operating and maintenance (servicing) instructions in the literature accompanying the unit. 

 

  Observance of polarity is essential. Double-check connections before turning the receiver or preamplifier 

on. The Phono 10 can be damaged if polarities are incorrect. 

 

  Turn your receiver or preamplifier and Phono 10 ‘off’ before plugging in or unplugging cables!!! 

 

  The Phono 10 is equipped with raised feet. They help to keep acoustic feedback into the unit at a 

minimum. They also provide a measure of protection against scratching any surface the unit might be 
resting on. 

Do not alter or remove them

.

 

 

  Do not stack anything on top of the Phono 10 (preamplifier, processor, source...etc.). 

 

 Always 

unplug the Phono 10 from the AC power source before removing the top cover and making any 

changes to the Moving Coil (MC) or Moving Magnet (MM) stage inside the unit. 

Important!
