For exploring the effect of asymmetrically mounted transducers and simulating left- and right-
handed users, it is possible to perform measurements on both ears. This is done by reversing the
position of the Cradle Positioner, with all graduations of the adjustment screws being repeated for
the left-hand position. A built-in quick release mechanism makes the cradle quickly dismountable,
making it easy to change handsets or to change between measurement on the left and right ears.
For users of the table top Telephone Test Head Type 4602-B, when it is fitted with the positioning
jig labelled HATS, the telephone test head corresponds directly to the HATS position of Type 4606.
