MANTIS COMPACT
Overview
Turn on the power switch  and place the subject be-
neath the Mantis viewing head.
Focus
The aim of the universal stand products is that the height of
the instrument is set to a comfortable viewing position and the
subject is then lifted (normally by hand) into focus. Thus maintaining
optimum ergonomics.
To set the height of the instrument, ensure the friction clamp  is
loosened then move the viewing head up or down until the required
viewing position is obtained and tighten the friction clamp.
Eye Spacing
Adjust the eye spacing control  to obtain a comfortable stereo view.
Note: Adjusting the eye spacing is very important for viewing
comfort and must be adjusted for each Mantis user.
Changing Lenses
To change the objective lens, twist and remove lens . Store the lens in the supplied container.
Fit and lock the chosen objective lens into the objective seat.
Head Counterbalance
When a lens has been changed, it may be necessary to adjust the head counterbalance. Adjust the
counterbalance screw
 (clockwise for lighter lenses or counter-clockwise for heavier ones) until the viewing head does
not drift up or down when unsupported.
Ergonomic Viewing
An ergonomic posture will ensure that users fully benefit from the advantages provided by the Mantis optical technology.
In setting up your Mantis, firstly arrange your workspace, paying attention to the heights of the chair and table.
When seated with a straight back, your eyes should be comfortably lined up with the Mantis viewing head. Forearms
should be supported by the work surface.
Operation
General Care
 When not in use, cover your Mantis with the dust cover provided.

 The Mantis lenses should be cleaned with a lens cleaning cloth.
