Powering Off the ARN/DC
To turn off the ARN/DC, move the power switch to the OFF position (0) by
inserting your finger or a narrow tool through the opening in the protective casing
to push the toggle switch down (refer to Figure 3-2 on page 3-10).
Turning the power switch off disconnects DC input to the internal power supply;
the power supply output shuts off. Use the ARN/DC power switch to shut down or
restart the ARN/DC without disconnecting the power-supply input wires.
Resetting the ARN/DC
The Reset button is set inside the ARN back panel and resides next to the flash
card slot, as shown in Figure 3-3.
