1-4. Power Supply
The unit works either on AC current (using the AC adaptor) or battery. When repairing or checking the
unit, however, AC-operation is recommended.
Power Voltage:DC 11 to 17 V
Power Consumption :65 W
m
. The AC adaptor AC-DN1 cannot be used to derive power.
. The AC adaptor AC-DN2A/DN2B can supply power to two VTRs simultaneously. The AC-DN2 with
serial No.11001 or higher can supply, too. If the above adaptor is used, power on the VTRs and load
cassettes in turn allowing for an inrush current.
. While the unit is battery-operated, the remaining battery capacity is displayed on the sub menu indica-
tor. When the battery is nearly dead, the WARNING indicator on the side of the LCD monitor will
blink. For details, refer to the operation manual supplied with the unit.
