OPERATION

OPERATION

Front Panel Power Switch

The SI-1260's master power switch is located on the front panel. Pressing the switch toggles between the ON (switch in) and the OFF (switch out) position. It must be in the ON position to enable the amplifier to activate regardless of the turn-on mode selected (see page 14). If you are going on vacation and/or would like to reduce power con- sumption while you are away, set the master power switch to the OFF position. When you would like to return to normal operation, set the switch back to the ON position.

Power LED Indicator

The SI-1260 features a bi-colored POWER LED indicating the power status of the amplifier:

Solid Yellow

The amplifier is plugged into a live AC outlet and the main

 

power switch is OFF (out position).

 

 

Solid Red

The amplifier is plugged into a live AC outlet and the main power

 

switch is ON (in position).

 

 

Fast Red Blinking

The AC line voltage is above or below the normal 120VAC.

(Three Times Per Second)

This will cause the amplifier to turn off.

 

 

Normal operation resumes once the AC line voltage returns

 

to 120VAC.

 

 

Slow Red Blinking

Internal defect. The amplifier should be returned to Niles
