Servicing

There are no serviceable parts in the amplifier. Do not attempt to 

service the amplifier. All servicing must be referred to authorized service 

personnel.

FOR YOUR PROTECTION
Ventilation

Your amplifier runs warm and requires free air circulation to the vents 

on the product.
Never place the amplifier in an enclosed space with restricted airflow, 

especially one with low vertical clearance.
Never place it near another source of heat, especially on top of 

something that is generating significant heat. Excessive heat will 

shorten the life of the product.

•  NEVER use the LS amplifier near water.
•  NEVER handle the amplifier while in contact with water.
•  NEVER let the amplifier come in contact with water.
•  NEVER spill water or other liquids into it.
