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.
