• When setting up the device, make sure that the AC outlet
you are using is easily accessible. If some trouble or
malfunction occurs, immediately turn off the power switch
also disconnect the unit from the power supply that is
connected to the EXT DC INPUT jack. Even when the
power switch is turned off, electricity is still flowing to the
product at the minimum level. When you are not using the
product for a long time, make sure to unplug the power
cord from the wall AC outlet.
• If the device is mounted in an EIA standard rack, carefully
read the section “Precautions for Rack Mounting” on page
