4-1-1. AC Power Supply

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.

.When using a plug adaptor (3-pin to 2-pin) for the AC power cord, be sure to connect the green wire to earth.

.Make sure that spike noise is not included when taking AC power from an inverter, etc.

.The internal backup battery is charged whenever the POWER switch is set to ON regardless of whether the unit is in standby mode.
