2. Preparation
Preparing a Power Supply
You can use a battery pack or AC power via an
AC adaptor.
For safety, use only the Sony battery packs
listed below.
Lithium-ion battery pack
BP-GL95B
AC adaptor
Adaptor that has a rating of 120 W or higher.
Using a Battery Pack
Insert the battery pack into the battery pack
mount (page 12) of the battery adaptor,
then slide the battery pack down to lock it in
place.
To remove it, unlock the battery pack by
sliding it up while pressing the battery release
lever (page 12), then remove it.
[Notes]
• Before use, charge the battery pack with the battery
charger.
• A warm battery pack immediately after use may not
be able to be fully recharged.
• Remove the battery adaptor while supporting the unit
by hand.
Checking the remaining battery charge
When recording or playback is in progress
using the battery pack, the current battery
remaining time and battery voltage are
displayed on the sub display screen
(page 36) and viewfinder/monitor screen
(page 14).
The unit indicates the remaining usage time in
minutes by calculating the available time with
the battery pack if operation is continued at
the current rate of power consumption.
If the remaining battery charge becomes
low
If the remaining battery charge decreases to a
certain level during operation, the remaining
battery capacity indicator flashes and the REC
lamp flashes to warn you.
If the remaining charge further decreases to a
level at which operation cannot be continued,
a battery-empty message appears.
Replace the battery pack with one that is fully
charged.
To change the message levels
Change levels using Technical > Batt./Voltage
Alarm (page 89) in the full menu.
Using AC Power (DC IN Power)
The unit works with AC power using a 120 W
AC adaptor.
11 V to 17 V and 22 V to 32 V input voltage
ranges are supported.
[Notes]
• When switching to the DC IN power supply during
battery operation, use a power supply with a voltage
in the range 12 V to 17 V for safer power supply
switching.
• When using a 22 V to 32 V power supply, it is
recommended that you first set the power switch to
the OFF position before connecting the power supply.
• Do not switch the DC IN power supply voltage
directly from a 11 V to 17 V power supply to a 22 V to
32 V power supply, or vice versa. This may cause a
malfunction.
Using a Battery Pack and DC IN
Power Supply Together
Whenever an active power supply is applied
using a battery pack and a DC IN power
supply, the DC IN power supply takes
precedence.
[Note]
When the power supply switches from battery operation
to the DC IN power supply, operation of the unit may
stop if the following occurs.
• Chattering of the connector contacts when inserting
the DC connector
• Voltage drop when switching between power
supplies (more prevalent when the external load is
greater)
