Connecting a DC power cord
1. Keep the upside of the DC plug shipped with the device on top and plug it in the DC receptacle
(see callout 1 in
Figure 10 ). (If you plug it with the upside down, the insertion is not smooth
because of the specific structure design of the DC receptacle and the plug.)
2. Use a flat-blade screwdriver to fasten the two screws on the DC plug to secure the plug to the DC
receptacle (see callout 2 in
Figure 10 ).
3. Connect the two cables on the other end of the DC power cord to the external power supply
system.
