To turn the amplifier off: Press and hold the amplifier
reset/power button (labeled "I/O") until both the amber and
blue lights come on. When the amber light goes out, let go of
the button.
Hint: The button is recessed. Use the tip of a pen when you
need to press it. Do not use an object with a sharp point, such
as a pin; it could damage the button.
To turn the amplifier on: Press the reset/power button for a
second. The blue light will flash to indicate the amplifier is on.
