001-60
To completely turn o power to the unit, pull out

completely separated from its main source of power. When
the power needs to be completely turned o, turn o the
power switch on the unit, then pull out the plug from the
outlet. For this reason, the outlet into which you choose to
connect the power cord’s plug should be one that is within
easy reach and readily accessible.

Also, make sure the line voltage at the installation matches
the input voltage specied on the AC adaptor’s body. Other
