Please follow the instructions in this manual to obtain the optimum results from this unit.
We also recommend that you keep this manual handy for future reference.
Important
When the YA-304 power cord is attached to the DP-0206 unit, the power voltage must be under
125 V. If the power voltage exceeds 125 V, prepare a different power cord.
When the power cord other than the YA-304 is attached, the unit can be used in areas where
the power voltage is 230 V.
