Power Plug
The Power cord can work with 12V input and plugs into
standard AC outlets. Be sure to use the correct plug for the
outlet.
For the AT-AR240E, connect one end of the Power cord to
the AC wall output and the other end to the Power Adapter.
Connect the round cable end of the Power Adapter to the
“Power” receptacle on the back of the AT-AR240E.
The AT-AR250E has either a 5V or a 9V DC Power plug.
Connect one end of the Power Adapter to the wall jack and
the other end to the Power plug located in the Rear panel of
the AT-AR250E. It will be powered automatically as soon
as the Power Adapter is plugged in.
ON/OFF Power Switch
The AT-AR240E has a two-position switch, ON and OFF
in the Rear panel.
When the switch is ON, it means that the power is supplied
through the AC Power Adapter. After the AC Power
Adapter is connected, flip the switch into the ON position.
The AT-AR240E will show a steady (green) Power LED.
The Sync LED will be a blinking (green) LED initially and
will become steady (green) once the connection is
established.
Check if the LEDs are ON for proper connections and initial
power-on operation.
NOTE: The AT-AR250E does not have the Power
Switch. It will automatically connect the device when the
Power Adapter is connected.
