Exam Lock is a feature of ReaderPen and LingoPen disabling some features in order to make it safe to use in exams.
Exam Lock supports two modes: i) all functions except Text Reader are deactivated and ii) all functions except Text Reader and Dictionary are deactivated. Choose the preferred mode before activating Exam Lock mode.
Exam Lock mode is locked with a PIN code and the same PIN code is used to revert back to standard operation mode. If the PIN code is unknown, it is possible to connect the ReaderPen/LingoPen to a computer, choose U-disk, and erase the lock.txt file.
