------------ Thanks for your purchase! Please read the instructions CAREFULLY. INSTRUCTIONS: - Type the 16-character password. For UPPERCASE characters use SHIFT key. Take your time while typing password, my suggestion is to use NATO Phonetic guide under password (a-alpha, B-BRAVO, C-CHARLIE...). - Once you are done typing password, hold down left CTRL key and press ENTER key twice (CTRL-ENTER-ENTER). (Password is to be typed using a standard US QWERTY keyboard). NOTE: Sometimes if using master password within Setup/BIOS, just pressing ENTER after typing password will do.
