any direction other than parallel with the connector body or it may break. If the tab breaks, use a

connector shell to unlatch it.
Loosen the two extraction arm captive screws using your thumb and forefinger. If the captive

screws are too tight to loosen by hand, use a No.2 Phillips screwdriver to loosen each screw.
