Be careful to use the correct voltage since usage of an incorrect voltage can lead to a fire or failure
of the unit.
At shipping, the AC voltage is set to either 100/120 V or 220/240 V. The setting is displayed on the
sticker on the AC voltage selector switch. If you peel off the sticker and change the voltage, be sure
to always re-check the usage voltage before using.

. When the AC voltage selector switch is set to AC 100/120 V, supplying AC 198 to 250 V may damage the
recording unit’s internal circuitry.
. When the AC voltage selector switch is set to AC 220/240 V, the recording unit will not operate when
supplied with AC 90 to 132 V.
. The AC power cord has a safety earth. Be sure to connect the power cord to an earthed socket.
