Features
The BC-DWX1 is a battery charger that can charge two
DWT-B03R or NP-BX1 units at the same time.
• In addition to charging the NP-BX1 battery packs alone,
the unit is capable of charging the battery packs while
they are inserted in DWT-B03R digital wireless
transmitters.
• Two power supplies are supported; AC adapter (not
supplied) power and PoE (Power over Ethernet) via
LAN cable.
• Connecting the unit to a network allows you to monitor
the charge status and change settings via the Wireless
Studio* computer software.
* Wireless Studio version 5.0 or later required.
Important Notes on
Operation
If the unit is suddenly taken from a cold to a warm location,
or if ambient temperature suddenly rises, moisture may
form on the outer surface of the unit and/or inside of the
unit. This is known as condensation. If condensation
occurs, turn off the unit and wait until the condensation
clears before operating the unit. Operating the unit while
condensation is present may damage the unit.
The life expectancy of the electrolytic capacitor is about 5
years under normal operating temperatures and normal
usage (8 hours per day; 25 days per month). If usage
exceeds the above normal usage frequency, the life
expectancy may be reduced correspondingly.
The battery terminal of this unit (the connector for battery
packs and AC adaptors) is a consumable part.
Power may not be supplied to the unit properly if the pins
of the battery terminal are bent or deformed by shock or
vibrations, or if they become corroded due to prolonged
outdoor use.
Periodic inspections are recommended to keep the unit
working properly and to prolong its usable lifetime.
Contact a Sony service or sales representative for more
information about inspections.
Notes on Cross Remote
• When supplying power to the BC-DWX1 via LAN cable
(i.e., Power over Ethernet), always use IEEE802.3af-
compliant PoE power sourcing equipment (e.g., PoE
hub).
For details on operating the PoE power sourcing
equipment or PoE hub, refer to the operating
instructions supplied with the device.
• When power supplies from both an AC adapter and PoE
power sourcing equipment exist, the AC adapter power
supply will be prioritized.
Maintaining Performance
• Be sure to check that there are no foreign objects or
particles in the charging ports before inserting
transmitters into the unit for charging. The presence of
foreign objects or particles may prevent proper charging.
• A charged battery will slowly discharge, even when it is
not in use. Be sure to charge the battery before each use
to ensure safe operation.
• Proper charging may not be possible if the unit or the
battery terminals are dirty. In such cases, wipe the
terminals with a dry cloth or cotton swab. When doing
so, make sure that the unit is turned off, and never touch
the charging terminals directly with your hands.

• Avoid usage and storage in the presence of excessive
dust or active gases, or in locations exposed to direct
sunlight.
Notes on the Battery
Charge the battery in an ambient temperature range of
10 °C to 30 °C (50 °F to 86 °F). Efficient charging may not
be possible at other temperatures.
Battery usage
• Battery performance drops in low ambient temperatures,
resulting in shorter usable durations. To extend the usage
duration in low ambient temperatures, place the battery
in your pocket, for example, and insert it in the unit
immediately before use.
• The battery is not waterproof. Be careful not to wet the
battery.
• Do not leave the battery in high temperature
environments, such as inside a hot car or under direct
sunlight.
• If the battery terminals are dirty, problems, such as
power not being supplied or charging not being possible,
may occur. In such cases, wipe the battery terminals with
a dry cloth or cotton swab to remove the dirt.
Battery storage
• Even during extended periods of disuse, charge the
battery about once a year to maintain its functionality.
After charging the battery, insert it in the unit, use the
storage function to discharge it, and then remove it from
the unit before storing it in a cool location with low
humidity.
• To prevent dirtying of the terminals, short circuits, or
other problems, place the removed battery in a plastic
bag, for example, and keep it away from metal objects
during transport or storage.
Battery life cycle
• The battery is a consumable part. The battery’s charge
capacity will gradually decrease as time passes and the
battery is used. When the battery's usable duration
becomes drastically reduced, it may have reached the
end of its life cycle. Purchase a new battery in such
cases.
• The battery’s life cycle will vary depending on storage
methods, usage conditions, and environments.

fLAN connector (RJ-45)
Use this to establish 10BASE-T/100BASE-TX network
connections. The communication speed will change
automatically according to the connected device.
Connect to Windows computers, hubs, etc.
When this connector is connected to a PoE-compatible hub
or power sourcing equipment, power can be supplied to the
unit via this connector.
CAUTION
For safety, do not connect the connector for peripheral
device wiring that might have excessive voltage to the
following ports:
Follow the instructions for this port.
• LAN connector
CAUTION
When you connect the LAN cable of the unit to peripheral
device, use a shielded-type cable to prevent malfunction
due to radiation noise.
gDC IN 12V connector
Connect an AC adapter (not supplied) here.
To avoid fire and malfunctions, use only the recommended
AC adapter (not supplied).
hRESET button
Use this to perform one of three functions; restore factory
settings, switch the charge mode, or enable/disable the
network function.
Use a pen or paper clip, for example, to press the button.
Perform RESET button operations without any
DWT-B03R or NP-BX1 units inserted.
Restoring factory settings
Hold down the button for 10 seconds. All the indicators on
the top of the unit will blink, and all setting values will
reset to factory settings.
Switching the charge mode
When you press the button while the CHARGE indicator
is off, the indicator will light for 3 seconds, allowing you
to check the current charge mode. Pressing the button
again during this time will switch between normal mode
and storage mode.
Press the button while the CHARGE indicator is lit to
switch the charge mode.
For details, see “Using the Storage Function” (page 7).
Enabling/disabling the network function
Connect the power supply while holding down the button
to enable/disable the network function.
When the network function is disabled, the NETWORK
indicator will not light, even when the unit is connected to
a network.
Connecting to the Power
Supply or Other Devices
• Always use a category 5 LAN cable.
• The LAN cable used to connect the unit to the device
(PoE hub, receiver, etc.) should not exceed 100 m (328
ft.) in length.
• If power sourcing equipment without a repeater function
is connected between the unit and the device (computer,
hub, etc.), the total LAN cable length between the unit
and the device should not exceed 100 m (328 ft.).
• Proper network connections may not be possible when
using modified LAN cables. Be sure to use
commercially available cables.
The connection methods and cable types used differ as
follows, depending on the method used to supply power to
the unit.
Supplying Power via PoE
The following are connection examples for supplying
power to the unit via PoE.
