1. Make certain that any software applications referencing the 702 are closed and that all file copy func-
tions to and from the 702 have been completed.
2. In Mac OS X highlight the drive icon on the desktop and select -e to eject the volume. Alternatively,
drag the drive icon to the trash in the dock.
2. In Windows, right-click the drive icon and select “eject.”
3. The cable between the computer and 702 can now be disconnected. If a future connection is going to be
made the cable can be left connected.
If the 702 is disconnected from the computer via an eject command and the FireWire cable is still
physically connected between the computer and recorder, the data connection can be made by enter-
ing the Setup Menu select FIREWIRE: CONNECTION. Alternatively, press the STOP button and HDD
button together to begin a FireWire connection.
Do not remove the CompactFlash card while FIREWIRE CONNECTION appears in the LCD.
Powering
The 702 is powered from either removable, Li-ion rechargeable batteries or external DC power. The
included, removable 7.2 V Li-ion cell can be used as a primary or backup power source. The 702
automatically chooses the power source based on the voltage level of the external power supply. If
it falls below a factory-set threshold, the unit will transition to Li-ion power. The transition between
external and removable battery powering is seamless and has no affect on recording or playback
operation.
During typical operation the 702 will run for approximately two hours from the included 1500 mAh
Li-ion battery.
Lithium Ion Rechargeable Battery
The 702 is compatible with Sony-mount L- or M-type Li-ion rechargeable batteries. Numerous power
capacities are available in these battery types, ranging from 1000 mAh to 7000 mAh. The 702’s mount
accommodates unlimited battery depth. Larger amp-hour cells provide more run time.
When powered by the removable Li-ion battery the LCD displays the battery voltage. The nominal
operating voltage for Li-ion batteries is 7.2 V, with operating voltages ranging between 6.5–8.5 V.
When the battery drops to 6.5 V, the LCD voltage display and the power LED begin flashing to warn
that the battery is nearly depleted. When the voltage reaches 6.3 volts the 702 will power down—any
recordings in-process will automatically be closed (stopped).
External Powering and Battery Charging
The 702 can be powered externally from 10–18 VDC (2 amp minimum). External DC fully powers the
unit and charges an attached Li-ion battery simultaneously using the 702’s onboard Li-ion charger.
The charger circuit operates whenever the unit is powered on and optionally when the unit is off,
depending on the external power wiring ( see below ).
DC input uses a 4-pin Hirose connector (Part # HR10-7P4P). There are two connection options.
External DC Input Wiring Operation
pin-2 to negative (–)
pin-3 to positive (+)
operates the on-board Li-ion charger when the unit is both turned on and off. Use when
plugged into AC power
pin-1 to negative (–)
pin-4 to positive (+)
operates the on-board Li-ion charger only when the unit is turned on—there is no exter-
nal current draw when powered off. Use when connecting to an external battery pack
