• 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 adjust-
ment 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.
