The Wireless Main Unit is the heart of the ARRI Wireless Remote System. It accepts the
hand controllers for focus and iris (WFU-1, WFU-3), zoom (WZU-1, WZU-3), camera
remote control (WRC-1), the Lens Data Display for Focus Puller (LDD-FP) and it com-
municates with the camera. Up to three Wireless Main Units can talk to one camera at the
same time.
The WMU-3 is small in size and lightweight, making it easy to hold for long periods of
time. In addition, the new radio modem has a more robust transmission and less power
consumption than its predecessor. An ergonomic hand strap assures that the whole unit
stays safely in the assistant’s hand. With the new software version (green washer) the
transmission is reenhanced.
Unique to the WMU-3 are the abilities to accept the Lens Data Display for Focus Puller
(LDD-FP) and to accept two control units at once using the Wireless Expansion Bracket
(WEB-3). It is possible, for instance, to use the Lens Data Display for Focus Puller (LDD-
FP) together with a Wireless Focus Unit (WFU-1 or WFU-3). Another possible combina-
tion is the Wireless Remote Control (WRC-1) with a Wireless Focus Unit (WFU-1 or
WFU-3). By employing two Wireless Main Units WMU-3, it is possible to have focus,
zoom, iris, camera remote control and the LDDFP all at the same time.
Compatibility: The WMU-3 communicates with UMC-3, URM-2, URM-3, Studio LDB-2
and Lite LDB-2. As power supply the Wireless Battery Unit WBU-3 has to be used;
WBU-1 and WBU-2 cannot be used. The WRC-1 needs to run at least software version
1.08. When using the WMU-3 with the Wireless Remote Control (WRC-1) or the Lens
Data Display for Focus Puller (LDD-FP), neither WZU-1 nor WZU-3 should be attached
between the units. LDD-FP and WRC-1 cannot be used on one WMU-3 at the same time.
Neither can two WRC-1 or two LDD-FP units.

The WFU-3 is used to control focus and/or iris. Focus and iris can be assigned freely to
hand wheel and slider, and electronic lens and knob limits can be easily set. In addition
it is possible to set mechanical knob limits.
The WFU-3 is similar to the WFU-1 except that it is lighter than the WFU-1 and the
index marker can be rotated 180° for better viewing. This movable index marker is
especially useful when the WFU-3 is mounted on the WMU-3, WHA-2 or WHA-3,
since the resulting remote control is so small that it can easily be swapped between the
left and the right hand and can be held at many different angles.
Compatibility: The WFU-3 can be attached to any Wireless Main Unit (WMU-1,
WMU-2 or WMU-3) for wireless operation with any camera or to the
Wired Handgrip Attachments WHA-2 or WHA-3 for wired operation with
ARRICAM, 416 Plus or 435 Xtreme.
