The Wireless Remote Control WRC-1 allows for remote operation of all current ARRI-
CAM and ARRIFLEX cameras. Its basic application includes the use as an extension of the
camera display in setups where the camera is difficult to access. More sophisticated features
are manual or programmed speed, shutter or iris ramps, speed change with exposure
compensation through shutter and/or iris, and shutter changes with exposure compensa-
tion through iris (or vice versa) for a shift in depth-of-field. The WRC-1 can be operated
wirelessly on the Wireless Main Units (WMU-1, WMU-2, WMU-3) or hardwired with the
Wired Handgrip Attachment (WHA-1, WHA-2, WHA-3).
Compatibility: For use on a Wireless Main Unit with the new radio modem WMU-2 or
WMU-3, the WRC-1 should always have the latest software version. Otherwise some
functions will not work. To work the WRC-1 together with the 235, SW-Version 1.22
is needed. It is not possible to operate the WRC-1 and the Lens Data Display for Focus
Puller (LDD-FP) on the same Wireless Main Unit. For wireless operation of WRC-1 and
LDD-FP at the same time, two Wireless Main Units must be used. The same is true for two
WRC-1 and LDD-FP units.

The LDD-FP is a small and lightweight display showing critical lens information and
camera status. It can be configured to show focus scale, zoom scale, iris scale and came-
ra status in any combination. Because of its small size it can be mounted in many ways,
allowing the assistant to see precise lens and camera information while keeping an eye on
the action. The screen of the LDD-FP is a high contrast Advanced TFT color screen with
adjustable brightness.
Compatibility: It is possible to use the LDD-FP together with the Cinematography Elec-
tronics Cine Tape Measure. The CTM calculates the distance between the filmgate and the
focus target. This distance is marked with a litle arrow in the focus scale of the LDD-FP,
as long as you hold a button on LDD-FP or WMA-3. The Lens Data Display for Focus
Puller (LDD-FP) can be operated wirelessly with the Wireless Main Unit 3 (WMU-3). To
use the LDD-FP on the WMU-3, compatible software is required for the LDD-FP, Studio
Lens Data Box LDB-2, Lite Lens Data Box LDB-2. UMC-3 and FEM-2. The LDD-FP is
not compatible with WMU-1, WMU-2, WHA-1, WHA-2 or WHA-3. It is not possible
to operate the WRC-1 and the Lens Data Display for Focus Puller (LDD-FP) on the same
Wireless Main Unit. For wireless operation of WRC-1 and LDD-FP at the same time, two
Wireless Main Units must be used. The same is true for two WRC-1 and LDD-FP units.
