Wait one minute to give the adhesive a chance to release and present a gap.

If the Anti-Clamp doesn't separate the adhesive after one minute, apply more heat and wait another minute. Be patient and let the Anti-Clamp do the work for you.

If, after several rounds of heating, the device doesn't show any signs of opening, twist the knob one quarter-turn.

Don't twist the knob more than three additional quarter-turns. Only use additional heat at this point. The more you twist the knob, the more likely the device is to suddenly pop open.
