    PER VISUAL INSPECTION: NO PHYSICAL DAMAGE TO CARTRIDGE HOLDER OR INPEN FRONT AND BACK SHELL WAS NOTED. CARTRIDGE HOLDER LOCKS PROPERLY IN PLACE. INPEN PAIRED WITH COMMERCIAL MOBILE APP WITH SMALL DOSE. PERFORMED LEADSCREW RESET TORQUE TEST. INPEN WITHIN SPECIFICATION (CW: 0.4 OZF-IN AND CCW: 4.90 OZF-IN). PERFORMED ENCODER BOND INVESTIGATION AND FOUND THAT THE ENCODER PATTERN WHEEL TABS ROTATING AND TRAVELING OFF THE KEYED SLOTS OF DOSE NUT GUIDES. ENCODER PATTERN WHEEL SHOULD NEVER ROTATE. THIS CAUSES AN UNEXPECTED TRAVEL OF THE ENCODER PATTERN WHEEL CREATING RESISTANCE TO DIAL AND DISPENSING.

UNABLE TO PERFORM BASELINE/WIRELESS FUNCTIONALITY AND DISPLACEMENT DOSE ACCURACY TEST. INPEN PASSED FRONT CAP INVESTIGATION.
