Before removing the amplifier from the box, please be careful of 
the following:

The Standby/Operation switch located on the rear of the amp is fragile, so care should be taken not 

to damage it when lifting the amp from their foam packaging.   Similarly, care should be taken not to 

damage the rear binding posts.

The pearl anodized coating on the industrial-grade chassis of the amplifier is highly susceptible to 

fingerprints,  so  we  recommend  wearing  cloth  gloves  when  handling  the  amplifier.    Wipe  away 

fingerprints using a dry cloth, wiping with the grain of the chassis.

Do not wipe against the grain or use materials which contain silicon, such as the cloths used for 

polishing eyeglass lenses.

Verifying that the amplifier has not been damaged in shipping:

(Before placing the amplifier for operation inspection and use in the system, the user may wish to 

install  the  attached  feet.  Please  understand  that  the  feet  are  for  convenience  only—in  order  to 

provide clearance for the user’s fingers when the amplifier must be lifted—and are not intended to 

be  “audiophile  grade.  ”      We  believe  that  because  isolation  devices  do  influence  the  sound  to  a 

greater or lesser extent, they should be chosen according to the user’s taste, which is why we do not 

attempt  to  provide  “high-quality”  feet  that  might  imply  recommendation  of  a  particular  tuning 

philosophy.   Most CF-080LS owners use their own isolation devices between the amplifiers and 

whatever stands or shelves they are resting upon.)

BEFORE hooking the amplifier up to the system via interconnect cables, plug in ONLY the power cord 

and then turn POWER switch into the ON position.

Please confirm that white LED on front panel for INPUT 1 is illuminating, showing that the amplifiers 

are operating properly.

If either the White LED ( INPUT 1) or level indicator is not illuminating, turn off the power to the 

amplifier, disconnect it from the wall outlet, and notify your dealer.
