3. Introduction
The Wireless Remote Control WRC-1 is a handy remote
control unit for use with all of the latest generation of
ARRIFLEX camera models: ARRIFLEX 16SR 3/Advanced,
16SR 3 HS/Advanced, 535, 535B, 435, 435ES
It enables the user to remotely control:
• the camera speed,
• the shutter angle of the mirror shutter, and
• the aperture of the lens (iris),
providing a wide range of compensation options for
constant exposure.
The range of functions offered by the WRC-1 is automatically
adapted to the limits of the camera and the lens control
motor to which it is connected. The large handwheel
permits sensitive adjustment of operational values, and
easy programming of end-stops for user-defined minimum
and maximum values.
The illuminated LCD provides quick, precise and comprehensive information about all the settings, the status of the
camera and the WRC-1, including all warnings.
The WRC-1 is the perfect addition to the ARRI Wireless
Lens Control System. Connected to the Wireless Main Unit
WMU-1 of the Wireless LCS it enables all functions to be
remotely controlled. The WRC-1 can also be connected to
the camera via cable using the Wireless Handgrip Attachment WHA-1 of the Wireless LCS system. However, the lens
remote-control functions are not available in this mode.
Introduction

3.1 Some typical applications
Exposure compensation
Differences in exposure, such as occur when moving from
outdoor to indoor in one take, can be easily, accurately
and repeatedly compensated for using the WRC-1.
A user defined program, which can be repeatedly activated,
is used to control either the iris or the shutter angle of the
mirror shutter – in this case the visible depth of field of the
image does not change.
Typical Applications
Altering the depth of field
Intentional adjustment of the depth of field at a constant
camera speed is another option available with the WRC-1.
In this case the mirror shutter angle is adjusted, using the
WRC-1, and the resulting difference in exposure is
automatically compensated with the iris of the lens.
10
Speed ramps
Altering the camera speed also changes the film exposure
time. In order to hold the film exposure constant when
changing the camera speed, either the shutter angle of the
mirror shutter or the aperture of the lens must be adjusted
accordingly. The WRC-1 allows the camera speed to be
changed while simultaneously retaining a constant exposure.
Several different compensation methods can be selected.
Example: the camera ramps up from 24 fps to 48 fps.
Two compensation options are available:
Compensation fps Shutter Angle Aperture Result
None 24 180 5.6 OK
48 180 5.6 1 T-stop under-exposed
Shutter Angle 24 90 5.6 OK
48 180 5.6 OK
Aperture 24 180 5.6 OK
48 180 4 OK
The required compensation type can be simply selected
using the COMPENSATION rotary switch on the WRC-1.
The camera speed can either be adjusted using the
handwheel, or it can be pre-set by programming a speed
ramp, which is activated by pressing the RAMP button.
Note: Adjusting the iris alters the depth of field.
Adjusting the shutter angle, on the other hand,
does not alter the depth of field. A small shutter
angle and a rapid camera movement, or fastmoving objects, may result in stroboscopic effects.
Typical Applications
Adjusting the shutter angle when using HMI
light may result in inconsistent film exposure.

The WRC/CAM sliding switch is used to select
the operating mode ➪ photo.
3.2.1 CAM mode
In CAM mode, the operator can access the same settings
and modes that are directly available on the camera itself.
The display on the WRC-1 shows the same information as
the camera display.
The MODE, SEL, SET and RAMP buttons have the same
functions as their respective counterparts on the camera.
A RUN LED is also integrated.
In the CAM mode, the OPEN button on the WRC-1 serves
as the PHASE button on the camera.
In CAM mode the WRC-1 serves purely as a camera
remote control unit, without any wider programming options.
The handwheel, the WRC and the COMPENSATION
rotary switches are without function in this operating mode.
12
3.2.2 WRC mode
The WRC mode offers convenient programming and easy
adjusting of the camera speed, the shutter angle and the
iris of the lens.
If the iris control is not activated (IRIS sliding switch ‘OFF’),
the OPEN button serves as the PHASE button on the
camera ➪ photo.
The left rotary switch (WRC) ➪ photo is for selecting
the parameter which is to be changed
(master value; for definition, see Glossary):
• camera speed,
• shutter angle or
• iris.
The right rotary switch (COMPENSATION) ➪ photo
is for setting how the change in exposure caused by the
adjustment is to be compensated for
(slave values; for definition, see Glossary).
Example: the WRC rotary switch is set to fps, the COMPENSATION rotary switch is set to Iris. The camera speed is
adjusted with the handwheel, while the WRC-1 automatically
keeps the film exposure constant, adjusting the iris of the
lens.
Depending on the chosen settings and the compensation
method, different ramp times are possible. The minimum
ramp time is calculated by the WRC-1.
Note: The term ‘adjust’ as used in this instruction
manual describes each direct adjustment of a
parameter using the handwheel.
Parallel to this adjustment, the WRC-1 can
automatically compensate the resultant difference
in exposure.
The term ‘ramp’ describes adjustment actions
which automatically take place over a predefined
period of time, i.e. these actions are not directly
controlled using the handwheel. They run continuously for a predefined period of time after
pressing the RAMP button. Resultant differences
in exposure can also be compensated for.

3.2.2.2 Overview of the settings available
with the COMPENSATION rotary switch
•off
In the ‘OFF’ position there is no exposure compensation
for the programmed ramp functions or the handwheel
adjustments.
(no slave values)
• Iris
In the ‘IRIS’ position the handwheel adjustments or the programmed ramp functions are compensated for by automatically adjusting the iris of the lens for a constant exposure.
(slave value: iris of the lens)
)
•
In the ‘)’ position the handwheel adjustments or the
programmed ramp functions are compensated for by
automatically adjusting the mirror shutter angle for a
constant exposure.
(slave value: mirror shutter angle)
• Iris / ) 50%
In this mode the exposure compensation is divided equally
between the shutter angle of the camera and the iris of
the lens.
(slave values: iris of the lens + mirror shutter angle)
• max. Iris
In this mode the change in the exposure is compensated for
by the iris of the lens. If the adjustment range of the iris is
not sufficient for the given end values, the remaining rest
will be compensated for by the mirror shutter angle. In this
case, the shutter angle proportion is evenly distributed over
the entire compensation range.
(slave values: iris of the lens + possibly mirror shutter angle)
• max.
In this mode the change in the exposure is compensated for
by the mirror shutter angle. If the adjustment range of the
shutter angle is insufficient for the given end value, the
remaining rest will be compensated for by the iris of the lens.
In this case, the aperture proportion is evenly distributed
over the entire compensation range.
(slave value: mirror shutter angle + possibly the iris of the lens)
• user
With this function ramps can be created which do not
result in constant exposure.
The iris of the lens, the shutter angle and the camera
speed can be combined as required.

5. Operation
5.1 Operating modes
5.1.1 CAM mode
The operating elements of the WRC-1 control the same
functions as the corresponding elements on the camera:
MODE, SEL, SET, and the RUN LED. In CAM mode, the
OPEN button corresponds to the PHASE button on the camera.
The RAMP button corresponds to the PROG button on the
camera. The handwheel and the WRC- and COMPENSATION
rotary switches are without function in this operating mode.
• All functions are comprehensively described in the
camera instruction manuals and are not repeated.
The display of the WRC-1 shows the same information as
the camera display in this operating mode.
Note: If the WRC-1 is only to be used in this operating
mode, it is advisable to set the WRC/CAM
sliding switch to CAM before the WRC-1 is
switched on. This ensures that the set frame rate
or a programmed shutter angle in the camera’s
PS/CCU mode and the WRC-1 in WRC mode
is not unintentionally altered.
In WRC mode the WRC-1 overwrites the
camera’s shutter angle and speed settings
(see Important instructions).
Camera programs which have been stored in
the camera via the CCU or the LCC are not
affected.
Forward or reverse run is set in the same way as on the
camera itself.
Note: With the ARRIFLEX 535 forward or reverse run is
set in the same way as on the ARRIFLEX 535B,
435, 16SR 3/Advanced.

camera as soon as this is switched on. When in use, the
background of the LCD of the WRC-1 is illuminated as
long as it is active.
The READY LED of the WRC-1 ➪ photo changes from
flashing red to a steady green once the communication
has been established with the camera. The WRC-1 is now
ready for use. In wireless mode the quality of the radio
connection must be read from the RF LED of the Wireless

5.3 Important instructions
• The WRC-1 controls
- the camera speed,
- the mirror shutter angle, and
- the iris of the lens.
All three parameters directly influence the exposure of
the film. In order to avoid unwanted results, and to
prevent the likelihood of incorrect use, all those
parameters controlled by the WRC-1 must be set and
controlled by the user. This also applies when one of
these parameters is not required for the currently
selected remote control: only when all three parameters
have been set (speed, mirror shutter angle and the
aperture) the film exposure is fully defined.
These values are defined separately for each mode,
i.e. the parameters can and must be individually set
for each mode.
Example: first of all a speed ramp is programmed and
Important Instructions
shot. Then only the shutter angle is remotely controlled
for a transition from an outdoor take to an indoor
take. It would not be desirable to continue using those
settings that had been active at the end of the speed
ramp for the next take. Instead, the values set by the
user for the respective modes are active after switching
over to the other mode.
• When operating in WRC mode, the speed or mirror
shutter angle should not be set on the camera itself, as
these are repeatedly written over by the WRC-1. The
WRC-1 is an active unit and its settings have priority
over those of the camera. The camera retains the last
settings sent by the WRC-1 in its memory. This applies
when switching from WRC mode back to CAM mode,
as well as when disconnecting the WRC-1 from the
camera.
• All programmed end-stops and parameters set on the
WRC-1 are stored for as long as required, even when
the unit has been switched off. It is therefore possible
that end-stops for the handwheel had been programmed, which are not available when using this
WRC-1 with another camera model (e.g. high-speed
settings). The WRC-1 recognizes the connected
camera model, but does not independently change the
stored values. If these stored values should lie outside
of the range available for the connected camera
model, a warning is displayed.

In WRC mode the WRC-1 overwrites the
camera-internal settings for the camera speed
and the mirror shutter angle.
This can result in the following takes being incorrectly exposed if the set values are not checked.
In practice this means, for instance, that the
angle of the mirror shutter set by the WRC-1 is
retained; this also applies when switching back
from PS/CCU to NORM.
The shutter angle is not automatically reset to 180°!
• The WRC-1 and ICU-1 may not be operated simultaneously.
The WRC-1 continuously sends values to the
camera when adjustments are carried out using
the handwheel or during ramp functions. The
radio connection must therefore function perfectly,
otherwise the correct exposure is not ensured.
The user must check that the RF LED is always
on green while the ramp function is running!
• All programs set using the WRC-1 are only stored in
the WRC-1 itself, and not in the camera. The RAMP
function of the WRC-1 therefore is not identical with
the camera’s own program function. It is therfore also
independent of a program which has been stored in
the camera using the CCU or the LCC. These camera
programs cannot be altered using the WRC-1. They
can only be activated and started in CAM mode like
using the operating buttons close to the camera display.
• The ZMU must always be switched on first if cable and
wireless units are used together.
• If a warning is displayed that the compensation limit values cannot be adhered to (readings ‘ANGLE RANGE’, ‘IRIS RANGE’, ‘SPEED RANGE’), while switching over the WRC or the COMPENSATION rotary switches, the end-stops or limit values are still programmed as described. The exceeded values can then be corrected in the relevant submenus.
• All warnings, such as when end-stops or limit values
are exceeded, are only shown in the main menu. The
submenus, on the other hand, are only used to define
all relevant values.

• If exposure compensation is not possible with the set
options – e.g. adjusting the iris cannot be compensated
for at the same time by the iris – the WRC-1 displays
the message ‘NO FUNC’ (no function) in the main menu.
The camera can still be run for test purposes
even if the READY LED on the WRC-1 lights up
red or flashes. In this case, however, the
exposure may not comply with the values set in
the in the WRC-1.
• In order to avoid inconstant exposure, all adjustment
processes and ramps under 6 fps are started in the
camera’s dark phase. At these speeds, brief delays of
up to 0.7 seconds at 1 fps may occur until the adjustment or the ramp is started.
• A non-linar phase is integrated into those adjustment
processes and ramps which run at speeds of under
4 fps to avoid inconstant exposures. As a result the

adjusted parameters do not move continuously.
• In order to operate the WRC-1 the following EPROM
versions must be used:
WMU-1: ........................................ 01.50 or higher
UMC-1:.......................................... 01.50 or higher
ARRIFLEX 435 .................................... 2.4 or higher
Please contact your nearest ARRI dealer or one of the
service stations to update the EPROMs or to acquire
the latest software version.
• As the end-stops of the iris ring on the ARRIMACROS
are changed with the focusing action, the ARRIMACROS
may not be used with the LCS or the WRC-1 system.
