POWER
The SP1.7 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 adjacent.
When the SP1.7 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. The RED
standby LED on the front panel illuminates.
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 SP1.7 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 units LED operating mode indicators.
NOTE: If your unit’s LCD backlight does not illuminate
when the SP1.7 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 SP1.7 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.
