About This Manual
Purpose of this manual
The purpose of this manual is to present a global
description of how to operate the viewfinder. Consult
the Operator's manual of your camera as required
during and after the installation process.
This manual is an integral part of the service policy.
It ensures that you will be able to install your viewfinder
to meet the requirements of your environment. The
manual provides first line service information so that
suitably qualified service personnel can detect and
repair faults, normally by module replacement.
Because of the complexity of some of the
components, second line service can only be carried
out at the specially equipped service centres and
information concerning second line maintenance is
not supplied in this manual.
Intended audience
The manual is intended as a guide to those with a
working knowledge of camera systems and
installation techniques. The first line detection and
repair of faults requires a general knowledge of test
and measurement techniques. The guide is so
designed that it can be used as wel to the viewfinder,
as wel a simple procedural guide to those who wish
to setup and start shooting immediately, and as a
reference work to be consulted as required during
the long life of the viewfinder.
Service policy

policy of Thomson Multimedia Broadcast Solutions
endeavours to ensure that help will be quickly on
hand in the unlikely event of anything going wrong.
The guiding principles of the Thomson Multimedia
Broadcast Solutions first line maintenance philosophy
are speed and cost effectiveness. First line
maintenance is dedicated to keeping your viewfinder
operational, despite a fault, by replacement boards
and the replacement of minor mechanical parts by
the user.
CAUTION

is protected according to safety
specification EN60529 up to level IPX3
(spraying water). Exposure to splashing or

into the slots.
d. Use the short screw (9) and the washers supplied
with the adapter to secure it to the left hole (as
seen from the front) of the sliding bar (8).
e. Attach the support bracket to the adapter ensuring
that the pins fit snugly (if necessary turn locking
ring to move it away from the adapter).
f. Use the long screw (10) supplied with the adapter

knurled screw (1) of the microphone support
bracket (2) on the viewfinder and open.
b. Slide the microphone into the split tube until the

c. Place the tube with the microphone into the
holder with the split facing upwards.
d. Ensure that the rubber supports at the back and
front of the holder fit into the rims (6)around the
tube.
e. Close the holder and tighten the knurled screw at
the top.
f. Connect the microphone cable to audio connector
(3) (mic) on the right side of the camera.
g. Place the microphone cable into the top clip at the
front of the camera and into clip (4) at the side of
the camera.(Pull and twist clip (4) to open it.)
Other microphones with a diameter of 21mm can
also be used, however, ensure that the phantom
power and the sensitivity of the input that match
that type of microphone are correctly selected in
the camera systems menu. Refer to Section 6 for
more information on selecting the audio inputs and
controlling the audio level.
Note:
· When longer microphones are used, it is not
necessary to place them in the split tube.
· For optimum operation, the microphone should
be mounted as straight as possible.
· Don’t allow the wind hood to touch the holder (7)
as this reduces the damping effect.
· By placing the split facing upwards, the
microphone cable does not touch the holder thus
avoiding mechanical pick-up.
· The microphone can also be connected to the
rear of the Triax adapter where a switch selects
the input. Refer to Operator's Guide Triax adaptor
for more information on connecting the
microphone to the rear connector.
