POWER
The SP1 uses a dual mode electrical power system. In the
electrical power input module located on the right hand side
of the rear panel, adjacent to the IEC power cord socket is a
large computer-style switch that controls the main electrical
power to the unit.This is the ONLY switch that actually
completely turns off all power to the unit. Please see the
illustration below.
When the SP1 is connected to an appropriate AC power
source, and the power switch is switched to the 'I' position,
the unit automatically sets itself into a STANDBY power mode,
where-in only the minimum necessary circuitry to respond to
the remote control's power-on command or the momentary
power toggle switch on the front panel are active.

Module
Activating the momentary POWER toggle switch (either up or
down) on the front panel or the POWER button on the
remote immediately takes the unit out of its STANDBY mode
into its normal operating mode.
The presence of AC power to the SP1 is indicated by the
illumination of the front panel LCD display, the illumination of
the LED corresponding to the source you last selected, and
the unit's LED operating mode indicators.
[NOTE: If your unit's LCD backlight does not illuminate when the SP1 is
plugged into an operating outlet, and switched out of STANDBY mode,
please check to see that the rear panel main power switch {mains switch}
is in the ON position.]
If the SP1 is to be unused for an extended period of time (i.e.
a vacation) it is strongly recommended that it be turned off
using the main power switch on the back panel.
