Tether Strap
Those unaccustomed to wearing glasses or who are moving around may wish to use a
tether strap (lanyard) for enhanced comfort and security.
Focus Adjustment
Your Wrap video eyewear can be worn over many styles of prescription glasses or you
can adjust the focus of each eye’s display independently from +2 to -5 diopters.
To adjust the focus:
 Lift the Focus Adjuster Cover, above the display section of the eyewear.
 A focus adjustment screwdriver is provided in a receptacle on the back of both
the Media Player and VGA Adapter Control Box.
 Remove the focus adjustment screwdriver and adjust each display to suit your
needs.
