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.
