Every decade or two, a quantum leap occurs in ideas and technology that sets the stage
for years to come. While most are content to follow the leader and add a feature or two, a
few innovators take the lead with revolutionary advancements that redene the future state
of the art. Paul C. Buff, Inc.™ has a track record for such innovations, rst in 1986 with the
forerunner of the modern self-contained studio ash – the White Lightning™ Ultra ash unit
- then again in 2001 with the rst full-featured, affordable-yet-professional monolight for the
new masses of young digital photographers – the colorful little light that could, and did – the
AlienBees™ ash unit.
We are now pleased to present the most advanced integrated studio ash system ever
conceived – at any price - with performance and features far beyond any “professional”
monolight. After two years of intense design, evolution, blood, sweat, and tears, welcome to
the brave new future of studio lighting - Einstein™, and the companion Cyber Commander™
extreme integrated wireless control system. Proudly designed and manufactured in America.

EINSTEIN™ SAFETY WARNINGS
Paul C. Buff™ Flash Units are designed for professional photographic use. As with all electronic equipment, users must observe all warnings and safety precautions. Carefully read all
operating instructions and safety instructions before use.
WARNING! HIGH VOLTAGE! Flash units contain high voltages and internal components that can store
dangerous voltages, even when the units are unplugged.
WARNING! Do not leave a ash unit unattended when it is turned on and / or in use. As with all electric
equipment, close supervision is necessary. Do not allow unattended children around this
equipment as potentially dangerous conditions may result. Turn the system OFF and unplug
the power cord when not in use.
WARNING! Do not operate or store a ash unit in or around water. Do not operate the units in wet,
damp or moist conditions, or in environments where water or other liquid could be dropped,
splashed, sprayed or spilled on the unit. High voltage equipment can cause electric shock
when operated in or near water. Your ash unit should only be used in dry, moderate conditions where the equipment is protected from rain, dirt, sand and dust.
WARNING! Do not use any Paul C. Buff, Inc.™ equipment without permission in restricted areas.
WARNING! Do not operate a ash unit on or around ammable materials such as newspaper, carpet,
wood sawdust, gasoline, etc. Keep the unit away from re, ames, and heated surfaces.
WARNING! Do not cover the unit during operation. Air circulation must be permitted. Do not obstruct
ventilation holes by covering the unit while in use or by operating from inside a carrying bag.
WARNING! Do not insert any foreign objects into any ventilation holes. Do not carry or store a ash
unit together with necklaces, hair pins, nails, paper clips, or any other small metal objects.
WARNING! Do not use ungrounded power cords, power outlets or power strips. Paul C. Buff™ Flash
Units may only be connected to 3-wire grounded AC outlets to avoid shock hazard. Do not
connect the unit to an ungrounded outlet or to a two-wire extension cord or adapter that
eliminates the ground prong. Do not use any cords that have been damaged.
WARNING! Paul C. Buff™ ash units contain no user-serviceable parts. Never open, disassemble, or
attempt to repair any components. Only qualied technicians should service the system as
incorrect disassembly can create an electric shock hazard. Fingers and other foreign objects
must never be inserted or dropped inside any of the vents. If the unit has been dropped
or damaged, discontinue use and contact Customer Service. Do not attempt to make any
changes or modications as any modications made, outside of those performed or approved
by Paul C. Buff, Inc.™, may present hazardous conditions and void the warranty. The only
user-replaceable components are the unit’s ashtube and modeling lamp.

WARNING! Do not use adapters on the power cord to connect to power lines / outlets of incompatible
voltages. This can damage the unit. For use in international locations, see page 21.
WARNING! The faceplate can get very hot during use. While in use, the unit’s faceplate, ashtube(s),
modeling lamp(s) and faceplate accessories (such as reectors, grids and umbrella poles) can get very
hot to the touch, remaining hot even after the unit has been powered down. Heat is intensied when
the unit is used in down-angle positions and/or when used with accessories that trap heat
(such as closed softboxes). Disconnect the unit from its power source and allow ample time
for the equipment to cool down before touching any component or any accessories.
1. Always mount the ash unit on a light stand during use. Before attempting to operate the ash
unit, make sure that it is securely mounted to a light stand. We offer various light stands in
assorted sizes - visit our website to learn more (www.paulcbuff.com). The stand mount is
compatible with most standard light stands having top couplers up to 5/8-inch in size.
2. Remove the shipping cover before use. Remove the front black cover before turning the unit on.
3. Do not touch the ashtube or modeling lamp with your bare hands. When replacing the ashtube
or modeling lamp, never touch a tube or lamp with your bare ngers. Always turn the unit off,
unplug it from its AC power source, allow it to cool, and use a clean cloth or insulating gloves
to remove or replace a tube and/or lamp. Do not allow your nger oils to contact the lamps
as this can cause excess heat buildup and may cause premature ashtube or lamp failure.
4. Only use approved ashtubes and modeling lamps. The Einstein™ unit should only be used with
the original ashtube and modeling lamp or an approved replacement tube or lamp. Please
see our website (www.paulcbuff.com) to nd replacement ashtubes and modeling lamps.
5. Use care when traveling with or transporting your ash unit. Always use the shipping cover
provided to protect the ashtube, modeling lamp, and frosted dome cover. Use appropriate
packaging to protect the unit against bumps and jolts that may damage the components.
6. When not in use, Paul C. Buff™ Flash Units should be stored in moderate climate conditions between
32ºF and 140ºF (0ºC and 40ºC), protected from water, dirt, sand and dust. Modern electrolytic capacitors normally have a long shelf life. However, if there is no charge applied for
long periods of time, they are more likely to have increased leakage current. This means the
capacitors may become warmer than normal until they stabilize, and the charge voltage may
sag more quickly during use, causing the units to recycle more frequently after ring. If you
need to store the unit for long periods of time (one year +), it is a good idea to occasionally
turn the units on at their lowest power setting, and slowly increase the power setting over a
period of 60 to 90 seconds while ring the unit using the TEST button after each increase.

7. Paul C. Buff™ Flash Units are designed for use with Paul C. Buff™ accessories. While other manu-
facturers design ash equipment and accessories that may claim compatibility with Paul C.
Buff™ equipment, each manufacturer denes their own contacts and latching mechanisms
which may or may not be suitable for safe use with Paul C. Buff™ equipment. We cannot
guarantee or offer our warranty when our equipment is used with accessories made by other
manufacturers and cannot accept liability for damages that may be caused as a result.
8. Observe power requirements and use the appropriate power cord. The Einstein™ ash unit requires
a suitable AC power source, but may be used on various power lines worldwide, from 95 to
265 Vac with 50 or 60 Hz outlets. The unit accomodates different line voltages without the
need to change settings or modeling lamp type. For use in North America, the unit arrives
with a 15-foot power cord that has a standard IEC connector on one end and a grounded,
three-pronged male plug on the other. This power cord connects to the ash unit on its back
control panel and is then plugged into a suitable 120 Vac, 50-60 Hz power outlet. To use the
Einstein™ unit in other areas of the world with varying power outlet congurations, you will
simply need an IEC power cord with the correct plug conguration specic to that area. A
suitable cord can be purchased locally, found in electronic and computer stores.
9. When shooting in an environment where a suitable AC power source is not available, we recommend the
exclusive use of our Vagabond™ Portable Power Systems. The Vagabond™ systems are designed
specically for Paul C. Buff™ ash units and power packs, offering a convenient, lightweight,
self-contained portable power source. We currently offer Vagabond™ models in both 120V
and 230V models. Visit our website (www.paulcbuff.com) to learn more.

1. The FUNCTION button is used to scroll between the individual screens on the LCD display to
select which screen is active for adjustment (each “screen” is a section of the display; all nine
screens are visible at all times). The screen actively selected for adjustment is highlighted in
blue. The unit defaults automatically to the Flash Adjustment Screen.
2. The ADJUST buttons are used to adjust the light’s various settings. Once a screen is high-
lighted for adjustment, the ADJUST buttons are used to raise or lower output (for the ashpower
and modeling lamp) or to scroll through the options for the setting.
3. The LCD Display is a backlit, high resolution, color screen that is divided into nine sections /
screens to display the current status of the various light settings.
4. The Sync Jack (1/8-inch / 3.5mm) is used for hardwired connection of the ash unit to your
camera using the provided ABSC sync cord.
Note:
Inserting a sync cord or dummy plug into the
jack does not disable the slave photo sensor, which is toggled on and off in a control screen.
5. The EASY SET button clears any programming and returns the unit to its default factory set-
tings. See page 8 for more details on EASY SET.
6. The TEST button allows you to test re (ash) the unit.

INITIAL SETUP
1. Remove the shipping cover. The Einstein™ unit ships with a black shipping cover positioned on
the faceplate over the ashtube, modeling lamp, and frosted dome to protect these items in
transit. This opaque black cover must be removed before use. Any protective packing material
around the frosted dome must also be removed. To remove the cover, slide either of the quickrelease levers to retract the four faceplate ngers holding the cover.
Note:
Do NOT replace the
shipping cover on a hot light. Allow the light to fully cool before installing the shipping cover.
2. Place the ash unit on a light stand. Place the Einstein™ unit on a standard light stand with the
stand’s top coupler placed inside the Einstein™ stand mount. Secure the hold by twisting the
stand mount tightening knob on the Einstein™ unit clockwise. Loosen the ratchet handle to
swivel the ash unit up or down. The handle has a ratchet action: pulling out on the handle
allows you to alter its position in order to make adjustments without hitting the housing.
3. Connect the supplied power cord. Connect the provided power cord into the power cord jack
on the back panel of the ash unit, then plug the cord into a 120 Vac or 240 Vac, 50 or 60 Hz
outlet, or to a Vagabond™ system. The Einstein™ unit will automatically sense the voltage and
frequency. Press the POWER button to turn the unit on.
Note:
When the Einstein™ unit is turned
off, it’s actually in STANDBY mode and can be turned on remotely by a Cyber Commander™
remote if it is tted with a CSXCV CyberSync™ Transceiver (both optional accessories, sold
separately - see page 18 for more details).
4. Begin in EASY SET Mode. The recessed EASY SET button allows instant setup for most users.
Pressing this button clears any special programming and sets the Einstein™ unit to the following
parameters (how the unit is shipped from the factory):
Model Mode = TRACK Flashpower: The modeling lamp tracks the ashpower output
(brightening or dimming automatically as the ashpower is adjusted up or down) for a
“What You See Is What You Get” modeling preview.
Recycle / Ready Indication = BOTH (Audible and Visual Recycle Indication): Recycle indication
is provided by an audible beep and by the modeling lamp dimming during recycle,
then restoring brightness when recycle is complete.
Color / Action = COLOR Mode: The emitted color temperature is held constant at 5600ºK
plus or minus 50ºK at any power setting or input voltage. See page 12 for more details.
Slave Eye Status = ON: The slave eye ash sensor is turned on.
Channel / Frequency: The optional CSXCV CyberSync™ Transceiver, if present, is set to
Frequency 1 and Channel 1. The CSXCV is sold separately, part of the CyberSync™
remote control system - see page 18 for more details.

5. Sync your camera. With your camera synced to the Einstein™ ash unit, pressing your camera
shutter will trigger simultaneous ring. For a hardwired sync, use the provided ABSC sync cord
(1/8-inch to PC-connection). Connect the 1/8-inch miniplug on the sync cord to the sync jack
on the back panel of the Einstein™ unit, then connect the cord to your camera’s PC jack or hot
shoe adapter. When the cord is rst connected, the unit should ash. Your camera can also be
synced to the unit using our optional CSXCV CyberSync™ Transceiver (sold separately, used
in conjunction with the CyberSync™ Cyber Commander™ or CST Transmitter). To learn more
about the CyberSync™ system, visit our website (www.paulcbuff.com/cybersync.php). See
page 18 for more details on using the CyberSync™ remote control system.
PRELIMINARY TESTING: With the Einstein™ unit turned on, operating the up and down ADJUST
buttons should increase or decrease both the ashpower and the modeling brightness by 1/10f
per click. If you hold either button in, the output will scroll.
DISPLAY FUNCTION: As you adjust the power using the ADJUST buttons, you should see the ash
and model bargraphs on the LCD display go up or down correspondingly. Since EASY SET
defaults the modeling lamp to track the ashpower, both bars should move in unison. If you
press the TEST button at any power, the unit should ash and the modeling lamp should dim.
When the unit is recycled, the modeling lamp will return on (at its previous brightness level) and
the audible recycle indicator beep will sound.

NAVIGATING EINSTEIN™ PARAMETERS
With the EASY SET button, most simple Einstein™ shoots are plug-and-play, not requiring parameter adjustments other than ashpower. For more advanced shoots, all parameters may be
easily manipulated using the different screens on the LCD display.
The LCD display is divided into nine sections / screens. The actively selected screen is highlighted in blue, beginning with the default Flash Adjustment Screen. Pressing the FUNCTION button
will sequence through the screens. If no adjustments are made for 10 seconds, the display will
revert to the default state with the Flash Adjustment Screen active. Regardless of which screen is
selected, the ashpower and modeling lamp bargraphs are always visible in the left column of
the display. These bargraphs indicate the power, relative to full power, in 1/10f increments. The
white bargraph (indicated by the lightning bolt symbol) displays the ashpower and the yellow
bargraph (indicated by the bulb symbol) displays the modeling lamp output. As adjustments are
made, both the bargraphs and the digital parameters in the Flash Adjustment Screen and Model
Adjustment Screen will update.
THE LCD DISPLAY
A. The Flash Adjustment Screen: When this screen is active, the ADJUST buttons are used to raise
or lower ashpower at 1/10f per click (holding either button scrolls the ashpower up or down).
At any ashpower setting, the digital numerical display in the screen indicates all ash data:
the current ashpower relative to full power, the color temperature, the t.1 ash duration, the
EU number, and the wattseconds. As adjustments are made, the data will change and the
ashpower bargraph will move up or down accordingly. If the modeling lamp is set to track
the ashpower, the numerical data in the Model Adjustment Screen will change and the modeling
lamp bargraph will move up or down as well.
B. The Model Adjustment Screen: This screen allows modeling lamp adjustment in either the
independent adjustment mode or tracking mode. In the independent adjustment mode, the
ADJUST buttons may be used to raise or lower the modeling brightness. The digital display of
watts and f-brightness relative to full (250 W) will update.
C. The Model Mode Screen: When this screen is active, you may select between the four modeling
lamp modes by pressing the ADJUST buttons.
On (Full Power): the modeling lamp remains at full brightness
Independently Adjustable: the modeling lamp is adjusted independently of ashpower
Track Flashpower: the lamp tracks the ashpower
Off: the modeling lamp is off

W: modeling lamp output
in watts
When the modeling lamp is set to track the ashpower,
there is a provision in the Model Adjustment Screen to offset
the lamp brightness, setting the output higher or lower
(not exceeding the normal minimum or maximum for the
installed lamp), while still maintaining the tracking feature.
The bargraphs will still move in unison, but with an offset
between the bars. This feature is useful when the light is
used with other lights having lower wattage lamps, and it is
desirable to maintain a constant ratio of model brightness
to ashpower for accurate previews. For example, if an
Einstein™ unit is used with an AlienBees™ B1600 unit
(640 Ws, 150 W lamp), it would be advantageous to set
the Einstein™ unit such that its lamp also produces 150
W when set to 640 Ws.
D. The Recycle / Ready Indicator Screen: In this screen, the
ADJUST buttons set the recycle indication behavior.
Audible: an audible beep sounds to indicate that
recycle is complete; the lamp does not dim during
recycle as this might be disconcerting to models
Visual: the modeling lamps will dim during recycle,
then restore brightness when recycle is complete
Both: both indicators are activated
Neither: both indicators are disabled; the ready
status will be indicated only on the back LCD
display (indicated by the Recycle / Ready Indicator
Screen turning from red to green)
When the ashpower is lowered, the Einstein™ unit
automatically dumps excess voltage. The screen turns
red during dump, then back to green when ready.
E. The Slave Eye Status Screen: In this screen, the slave
status is set with the ADJUST buttons.
On: the slave eye is on, causing the Einstein™ unit
to ash simultaneously whenever it “sees” the
ash from another unit (still active whether or not
the sync jack is in use)
Off: the slave eye is turned off

EINSTEIN™ by Paul C. Buff
F. The Action / Color Screen: In this screen, the ADJUST buttons are used to change the mode
between Action Mode and Constant Color Mode (more details in the following section).
G. Channel Screen and H. Frequency Screen: In these screens, the ADJUST buttons are used to set
the channel and frequency of the optional CyberSync™ CSXCV Transceiver, if present. Each
ash unit / transceiver in the setup should be set to its own unique channel. All ash units /
transceivers should be set to the same frequency (see page 18 for more details).
IGBT ADVANTAGES
Even the most expensive professional monolight ash units usually control ashpower by
varying the voltage applied to the ash capacitors. This simple and inexpensive method has
three distinct limitations to the achievement of truly professional performance:
1. The range of power reduction is typically limited to 1/8 to 1/32 power, often resulting in an
inability to achieve low aperture settings with close lighting techniques.
2. As power is reduced, the ash duration becomes longer - typically twice as long at minimum
power relative to maximum power. The median t.1 ash duration of the ten most popular pro
monolights ranges from 1/200 second to 1/400 second – too slow for sharp freezing of action
in sports, dance and other rapid movement shots (see graphs on page 15).
3. Color temperature typically varies by 75ºK to 80ºK per f-stop of power reduction, resulting
in about 400ºK color difference between minimum and maximum power. The Einstein™ unit
employs proprietary advanced digitally controlled IGBT technology to control ashpower.
This results in an extreme range of power reduction (1/256 power) in precise 1/10f stops. As
power is reduced, the t.1 ash duration also decreases dramatically instead of increasing. This
technology allows the Einstein™ unit to maintain a constant color temperature throughout
the entire 256:1 power range.
Two operating modes are provided – ACTION Mode and CONSTANT COLOR Mode. In Action Mode,
the t.1 ash duration shortens rapidly from 1/588 seconds at full power to 1/13,500 seconds at
minimum power for incredible action freezing capability, but the color temperature increases
as power is reduced. In Constant Color Mode, the t.1 ash duration drops less rapidly, to a
minimum of 1/8000 second, while maintaining a constant color temperature of 5600º K (+/50º K) throughout the entire power range. The internal processor controls the accuracy and
repeatability with very high precision (see the chart on page 13 and graphs on page 15).
ACTION Mode: In Action Mode, the color temperature rises as power is reduced, but the t.1 ash
duration is minimized even further for maximum action stopping capability where absolute
color consistency is secondary to motion freezing. At 1/2 power in Action Mode, the t.1 ash
duration is approximately 1/2000 second and the color temperature is approximately 5750º K
(absolute values of ash duration and color temperature are indicated on the rear LCD display).

[
13
]
CONSTANT COLOR Mode: In this mode, the emitted color temperature is held constant at 5600º K,
plus or minus 50º K at any power setting or input voltage. At full power, the t.5 ash duration is
1/1600 second and the t.1 time is 1/568 second. As power is reduced to 1/2 power the color
remains constant, while the ash duration decreases to 1/1351 second t.1 (note that with IGBT
control, the t.5 spec is no longer meaningful, so only the t.1 ash duration appears on the rear
LCD display). As power is further decreased, the color temperature remains constant and the
t.1 ash duration falls ultimately to 1/8000 second at the lowest power settings.

EU Numbers: When lights with different wattsecond ratings are mixed in a studio, terms like
“1/4 power” or “-3f” don’t tell the user how much light one unit outputs compared to another.
In order to allow a direct comparison between lights of different ratings, several European
manufacturers have instituted a numbering system that directly compares lights in 1/10f
increments without requiring calculations or wattsecond math conversions. The EU Number
denes a 6400 Ws power level as EU10.0, and each 1/10 f-stop change is represented by a
one digit change in the decimal. Thus, EU9.9 is 1/10f less power than EU10.0. A full f-stop
change is a one digit change before the decimal point. If your main light is EU6.4 and your ll
is EU5.3, you quickly know your ll light is 1.1f less powerful than your main light.

EINSTEIN™ by Paul C. Buff
CONVENTIONAL FLASH VS. IGBT CONTROL
Conventional Variable Voltage Control: Figures 1 and 2 show the ash waveform from a conventional variable voltage monoash. As power is reduced, both the t.5 and t.1 ash durations
become longer as power is reduced. Note that even beyond the t.1 point the ash continues
to trail off slowly, adding motion blur. The color temperature drops as power is reduced.
Einstein
TM
E640 IGBT Control: In Figures 3 and 4 below, notice the ash abruptly shuts off at
whatever point is needed to produce the desired output. The t.1 ash durations can be as fast
as 1/13,500 second at low power, producing crisp action freezing. But the color temperature
rises as power is reduced. This depicts the EinsteinTM Action Mode. In the Constant Color
Mode, the EinsteinTM processor compensates by adjusting both the shutoff time and the
voltage such that a constant 5600ºK color is achieved. The ash duration drops less rapidly
as power is reduced, but still produces very short t.1 times (1/8000 second at minimum
power) and extremely sharp action freezing. See the graphs below and on the following page.

USING ACCESSORIES
All Paul C. Buff™ accessories are sold separately.
Visit
our website (www.paulcbuff.com) to learn more
and see our full line of compatible accessories
and light modiers.
Remote Controls: The Einstein™ unit includes a
slot for the CyberSync™ CSXCV Transceiver
for use with the Cyber Commander™ remote
control to provide complete wireless ring and
parameter adjustment. With this setup, the Cyber
Commander™ unit can be used to remotely
power on an Einstein™ unit that is plugged into
a power source. The unit may be used with all
CyberSync™ transmitters and receivers (see
page 18 for more). Einstein™ may not be used
with the LG4X wired remote control or older Paul
C. Buff™ remotes incorporating the telephone
cord connection. The unit is compatible with
most other third party triggering receivers (such
as the PocketWizard®). A 1/8-inch to 1/8-inch
non-attenuated mini male mono cord such as
our CSSC is required to connect the receiver to
the Einstein™ unit. The Einstein™ is additionally
compatible with the PocketWizard® PowerMC2
for use with the PocketWizard® system.
Softboxes and Reectors: The Einstein™ faceplate
with the standard BUFF™ / Balcar mount has
four holding ngers that expand and contract
to hold various reectors as well as speedrings
for softbox attachment. While the Einstein™ unit
does not arrive with a particular reector, for
general use we recommend the 8.5HOR 8.5-inch
high-output silver reector. The unit is compatible with our full line of reectors, beauty dishes,
the LiteMod™ mainframe and associated accessories, and our foldable softboxes, octaboxes
or stripbox as well as retired models of Paul C.
Buff™ softboxes.

When using softboxes by other manufacturers,
you will need to get a Paul C. Buff™ compatible speedring. When mounting accessories to
the faceplate, ensure that all four holding ngers
are within the opening and that the quick-release
levers have returned rmly to the open position.
Failure to do so can result in the unintended
release of the modier from the light.
Note:
The Einstein™ unit mounts all accessories
that t previous Paul C. Buff™ lights except the
obsolete WL130, WL5,000 and WL10,000 models.
The PLM™ System and Umbrellas: The Einstein™
unit has an umbrella shaft that runs along the top
length of the unit housing, tting standard umbrella
poles up to 23/64” (approx. 9mm) in diameter. It
may be used with the PLM™ system (both current
and previous models) as well as retired Paul C.
Buff™ umbrellas. The PLM™ system’s on-axis
speedring mount may be used as well.
Light Stands: The Einstein™ unit must be securely
mounted to a light stand for use. The stand mount
is compatible with most standard light stands
having top couplers up to 5/8-inch and may be
used on our full line of Paul C. Buff™ light stands.
Travel Gear: One Einstein™ unit can be carried in
our PCBBAG Paul C. Buff™ single-light carrying
bag (with the shipping cover, either the 7” or 8”
reector, cords and room for other small accessories).
Note:
The PCBAG is for around-town travel
only; it is not suitable for airline travel. For consid-
eration of travel cases from other manufacturers,
the unit’s dimensions are 7” height x 5.4” width x
7.8” length (with lamps, dome and shipping cover
in place; mounting hardware attached).
If you need help or have questions about using
a particular accessory with your Einstein™ ash
unit, contact our Customer Service team for
assistance.

EINSTEIN™ by Paul C. Buff
USING EINSTEIN™ WITH THE CYBERSYNC™ SYSTEM
For complete wireless ring and full parameter adjustment, the Einstein™ unit can be used with
the CyberSync™ CSXCV Transceiver and the Cyber Commander™ remote control. With this
setup, the Cyber Commander™ unit can also be used to remotely power on an Einstein™ unit
that is plugged into a power source. For complete information about the optional CyberSync™
system, visit our website (www.paulcbuff.com/cybersync.php).
Setting up the Einstein™ unit with the Cyber Commander™ remote: Unlike setting up vintage Buff™
lights in the Cyber Commander™ remote, it is not necessary to perform the tedious “Spec
Lights” and “Light Settings” steps required by lights that communicate via CSR+ or CSRB+
receivers. The Einstein
TM
/ CSXCV combination allows all of the EinsteinTM unit’s back panel
settings to automatically be transferred to the Cyber CommanderTM remote. Acquiring this
information and recognizing Einstein
TM
units is accomplished by using one of the methods
detailed below.
Note:
Below, there are two instruction sets for setting up EinsteinTM ash units
with the Cyber Commander™ remote. The rst set (NEW SETUPS) starts the setup process from
scratch, erasing any programming already made in the Cyber Commander™ remote. Any
information erased will have to be reprogrammed, including light specications and names. To
keep existing light information programmed in your Cyber Commander
TM
remote, please follow
only the steps in the second section (EXISTING SETUPS).
Einstein™ and CyberSync™ NEW SETUPS: Use these instructions to set up the Einstein™ unit as
part of a new setup with no existing lights - this will erase any information already programmed
in the Cyber Commander™ remote!
1. Using the FUNCTION and ADJUST buttons on the Einstein
TM
unit’s back panel, ensure that the
unit is set to a unique channel not shared by any other light / CyberSync
TM
receiver, and set
to the same frequency as your Cyber CommanderTM remote.
2. Enter the Cyber Commander
TM
remote’s setup menu by scrolling to the right with the right
joystick. In the setup menu, use the right joystick to highlight and select OPEN MEMORY.
3. Using the left joystick, select STUDIO in the lower left corner. Your screen should now read
OPEN ALL FROM STUDIO, followed by SYNC CYBER COMMANDER FROM STUDIO LIGHTS.
4. Press in on the right joystick. SYNC CYBER COMMANDER FINISHED OPENING should appear.
5. The Einstein
TM
unit is now dened as Einstein 640 and the remote is set with all parameters
for the unit as they appear on its back panel. No further action is required. Any parameter
changes should now be made with the Cyber Commander™ remote as any changes made
on the back panel will be overridden by the settings in the Cyber Commander™ remote.
Note:
All non-digital Paul C. Buff™ ash units (White LightningTM, AlienBeesTM, and Zeus™
units) will require the specication process as outlined in the Cyber CommanderTM manual.

]
Einstein™ and CyberSync™ EXISTING SETUPS: Use these instructions to set up the Einstein™ unit
as part of an existing setup with ash units that have already been programmed and specied
in the Cyber Commander™ unit - already programmed lights will remain unaltered.
1. Using the FUNCTION and ADJUST buttons on the Einstein
TM
unit’s back panel, ensure that the
unit is set to a unique channel not shared by any other light / CyberSyncTM receiver, and set
to the same frequency as your Cyber CommanderTM remote.
2. Enter the Cyber Commander
TM
remote’s setup menu by scrolling to the right with the right
joystick. In the setup menu, use the right joystick to highlight and select OPEN MEMORY.
3. Using the left joystick, select the CHANNEL corresponding to the channel number you
have set on the new Einstein™ unit that you are about to recognize. By opening new lights
individually, one light channel at a time (instead of using OPEN FROM STUDIO), you will avoid
losing any programming already performed for existing lights. Your screen should now read
OPEN CH(XX) FROM STUDIO, followed by SYNC CYBER COMMANDER FROM STUDIO CHANNEL (XX).
4. Using the right joystick, press in. Almost immediately, SYNC CYBER COMMANDER FINISHED
OPENING should appear.
5. Repeat steps 3 and 4 to add other new Einstein™ ash units to the existing setup.
6. Each Einstein
TM
unit is now dened as an Einstein 640 and the remote is set with all parameters
for each unit as they appear on each back panel. No further action is required. Any parameter
changes should now be made with the Cyber Commander™ remote as any changes made
on the back panel(s) will be overridden by the settings in the Cyber Commander™ remote.
Note:
Once you have completed the process of adding new lights, it’s always a good idea to
store the new or revised setup to one of the 52 available storage locations for future reference.
See your Cyber Commander™ manual for details on storage locations and saving setups.

REPLACING EINSTEIN™ COMPONENTS
Certain components arriving with the Einstein™ ash unit are
consumable and will require replacement based on normal use.
All Paul C. Buff™ replacement components are sold separately.
Visit
our website (www.paulcbuff.com) to learn more.
Flashtube: The user-replaceable ashtube that arrives with the
unit is a 12mm single-ring, UV-coated tube (daylight-balanced
at 5600º K). This tube has a 200,000+ ash lifespan, dependent
upon power levels and frequency of shooting. For future replacement needs, the part number is MAXFT12MMUV (www.
paulcbuff.com/ashtubes.php). Do NOT use any other tube.
Modeling Lamp: The user-replaceable modeling lamp that arrives
with the Einstein™ unit is a bayonet-style 250 Watt modeling
lamp, also having a lifespan dependent upon power levels and
frequency of use. For future replacement needs, the modeling
lamp part number is JD250W (available on our website at www.
paulcbuff.com/modelinglamps.php). We additionally offer a
lower-wattage 150 Watt modeling lamp (part # QL150) and a
lower-wattage 25 Watt modeling lamp (part # 25W) for use in
the Einstein™ unit. When using the Vagabond Mini™ Lithium
system, as the system cannot power the supplied 250 Watt
modeling lamp, we offer the 25 Watt lamp that may be used for
brief modeling previews.
Note:
Never handle ashtubes or lamps
with your bare hands. Wear gloves or use a clean, dry cloth or
paper towel to avoid contamination by skin oils.
Fuse: The user-replaceable fuse holder (located on the back
panel of the unit) takes an SR5-F type 8A fuse. Each unit arrives
with this fuse in place on the unit and an additional back-up fuse
is provided. If further fuse replacement becomes necessary,
additional fuses may be purchased at electronic suppliers such
as Digi-Key (www.digikey.com, see part # WK6240-ND).
Note:
If you nd that the fuse requires replacement multiple times,
contact us as there may be a problem.
Should you misplace any other system components, we offer
replacements for the power cord (part # UPC15), sync cord
(part # ABSC), frosted dome (part # 1060836), and shipping
cover (part # 1060203). Contact us for assistance.

USING EINSTEIN™ ON GLOBAL POWER LINES
The Einstein™ ash unit offers global plug-and-play with automatic power switching that allows
the unit to operate on power lines from 95 to 265 Vac, 50 or 60 Hz, automatically sensing the
voltage / frequency and adjusting accordingly with no user attention required. The unit can
tolerate momentary power line voltages as low as 35 Vac from the Vagabond Mini™ Lithium
portable power system or from other similar pure sine inverters without crashing, whereas many
competitive digital ash units crash if the input voltage falls below about 80 to 90 Vac. No user
intervention or lamp changing is required to operate at different AC line voltages.
Note:
The Einstein™ ash unit’s precision WYSIWYG modeling lamp tracking will not allow the
modeling lamp to reach full brightness at input voltages below 115 Vac, but will still track at
input voltages from 95 to 265 Vac.
For use in North America, the unit arrives with a 15-foot power cord that has a standard IEC
connector on one end and a grounded, three-pronged male plug on the other. This power
cord connects to the ash unit on its back control panel and is then plugged into a suitable
120 Vac, 50-60 Hz grounded power outlet. For use in Australia and China, we offer an optional
power cord, available in both 15-foot (part # VM-UPC15-230V) and 3-foot (part # VM-UPC3-
230V) lengths (both sold separately, visit our website at www.paulcbuff.com/powercords.php).
To use the Einstein™ unit in other areas of the world with varying power outlet congurations, you
will simply need an IEC power cord with a standard IEC connector on one end and the suitable
plug on the other end with the correct plug conguration specic to your area. A standard
power cord can be purchased locally, found in electronic and computer stores.

PORTABLE POWER
For portable, battery power, we recommend the use of our Vagabond Mini™ Portable Power
System (sold separately, visit our website at www.paulcbuff.com/vagabond.php to learn more).
The Vagabond Mini™ Lithium system provides a reliable, portable, current-limited, true sine
wave power source for one to four Paul C. Buff™ ash units.
Standard 120V Vagabond Mini™ Lithium System: When using the Einstein™ unit with the standard,
supplied UPC15 power cord (120 Vac), the unit plugs into one of the standard outlets on the
120V Vagabond Mini™ Lithium system.
International 230V Vagabond Mini™ Lithium System: When using the Einstein™ unit internationally,
with a Chinese/Australian Type I power cord (230 Vac), the unit plugs into one of the outlets on
the 230V Vagabond Mini™ Lithium system.
The design of the Einstein™ unit allows crash-free operation of multiple units from the Vagabond
Mini™ Lithium system and other current-limited, pure sine wave battery inverter supplies from
other manufacturers. The Einstein™ unit can tolerate momentary power line voltages as low
as 35 Vac from our older Vagabond™ II portable power system or from other similar pure
sine inverters without crashing, whereas many competitive digital ash units crash if the input
voltage falls below 80 to 90 Vac.
Note:
An idle Einstein™ unit draws 9 watts from the battery; when switched off, the unit still draws
4 watts. To save battery life, turn off the Vagabond Mini™ Lithium system during prolonged
setups between shots.

FAQ
Q: Why are other ash units causing my Einstein™ ash unit to re?
A: The Einstein™ unit has a built-in slave tripper that is designed to sense ashes of light (both
visible and infrared) and re the unit simultaneously. Any ash that it “sees” can trigger it,
including the ash from another unit in your setup, a conventional on-camera ash (and its preash), and/or an infrared remote transmitter. Although this gives you more options for triggering
the lights in your setup, the presence of extraneous triggers must be considered when you are
not the only photographer in the area. Other photographers’ ashes (whether on professional
or even disposable cameras), and infrared remotes can inadvertently trip your ash unit. To
eliminate this possibility, you can disengage the slave eye.
The slave eye status is set on the unit’s LCD display. Use the FUNCTION button to scroll to
the Slave Eye Status Screen, then use the ADJUST arrows to turn the slave eye OFF. The slave
status can also be set using the Cyber Commander™ remote control, if present.
Note:
Unlike
rst generation Paul C. Buff™ units, connecting a sync cord or dummy plug will NOT disable the
slave. It must be manually disabled on the LCD display or via the Cyber Commander™ remote.
Q: I made a change to a setting on the back panel of my Einstein™ ash unit, then when I went to take a
photo, the settings reverted. Why didn’t they stick?
A: Are you using a Cyber Commander™ or PocketWizard® remote cotnrol? The Cyber
Commander™ unit controls the settings for any ash units in the setup that have been specied
with their associated receivers. The settings in the Cyber Commander™ unit override any
manual adjustments made on the back panel of the unit. Similarly, some models of PocketWizard® remote controls may override the settings on the back panel of the ash unit. You will need
to make your desired adjustments from the Cyber Commander™ or PocketWizard® remote.
Q: My Einstein™ ash unit will not re. I’ve tried triggering the ash and pressing the TEST button on the
control panel, but neither will re the unit. Is the ashtube dead? Is there a problem?
A: Do you hear a faint clicking sound when you press the TEST button? If so, most likely the unit
simply needs a new ashtube. Under normal use, ashtubes exhaust over time (the standard
MAXFT12MMUV ashtube has a 200,000+ ash lifespan). If it seems too soon for your ashtube
to be exhausted, it is possible that it has come unseated or been damaged in transit. Do you
see any cracks or breaks in the ashtube or ashtube legs? If you need to replace or reseat the
ashtube, rst turn the unit OFF and unplug it from its AC power source, waiting ten minutes
for the unit to cool. Wearing gloves or using a clean cloth, replace or reseat the ashtube,
pressing down over each leg to ensure that the tube is fully seated. If replacing or reseating the
ashtube does not solve the problem, contact our Customer Service team to further discuss
and diagnose the situation.
