Thermal image focusing (Ti models only)
The thermal imaging cameras feature a manual focus ring which is accessible when
the front lens cover is removed.
To focus the thermal camera
1 Using a 2.5mm hex key, remove the
two retaining screws either side of
the thermal camera lens cover.
2 Carefully lift off the thermal imaging
lens cover and keep it free from dirt
or the possibility of scratching.
Keep the two screws and the internal
o-ring seal safe for reassembly.
3 Using the keyboard controls, direct
the camera towards a typical scene
that will be monitored.
4 While viewing the output from the
thermal imaging camera (either
directly, if possible, or under instruc-
tion from a colleague), twist the outer
lens until the thermal screen image is
brought into focus.
5 When complete, ensure that the o-ring seal is
correctly in place on the rear side of the lens
cover and place it onto the camera front.
6 Replace the two retaining screws and tighten.
