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.

Setting Check Sheet
It is recommended to make a photocopy of check sheets given in this appendix and write down setup
conditions such as switches’ setting in the check sheets according to application.
If setup conditions are noted, the settings can be returned easily to its original condition after being
changed temporarily (when operating condition changes and so on).
And when the unit is to be checked, maintained or repaired, please attach the filled-in check sheets to the
unit.
If system combinations are frequently changed according to use, it is convenient to prepare check sheets
for every system. Make use of the check sheets to avoid mistakes.
