OPERATION:

Power Switch

The power switch is a rocker-type switch. It is located on
the left side of the front panel. To turn the amplifier on, push
in on the top of the switch. To turn the amplifier off, push in
on the bottom of the switch.
The green power LED should light up when the switch is in
the on position.
When the power is switched off, the LED may takes several
seconds to go out; this is normal.
If the POWER LED fails to illuminate when
the switch is in the ON position:
1- Check the AC cord and insure that both ends are fully
inserted into their receptacles. If the power LED still fails to
illuminate,
2- Check the AC outlet for voltage with a circuit tester or
known good device (lamp, etc.).
3- Make sure that the amplifier is not in STANDBY mode. If
the amplifier is being controlled by one of its DataPort
connectors, the amplifier may be in standby mode. Verify the
AC power status from the DataPort device controlling the
amplifier.
