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.
Itensuresthatyouwill be able to install yourviewfinder
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.

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

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
theinput. Refer to Operator's Guide Triax adaptor
for more information on connecting the
microphone to the rear connector.
