4.1.1Locking the Front Panel

A special combination of buttons (the Locking Sequence) makes it possible to freeze control input such that the QuadScan will not respond to Control Panel or IR remote or RS-232/422 commands until a second special combination of buttons (the Unlocking Sequence) is entered. The locking sequence consists of: Advance the panel menu to “QuadScan”, first press the “down” key and while still pressing the “down” key, press the “-“ key. The LED readout will indicate "LOCKED" and all further input will be ignored until the Unlocking Sequence is entered. The Unlocking Sequence consists of: First press the “down” key and while still pressing the “down” key, press the “+“ key. Locking will persist even after the QuadScan is power cycled. All input from the IR remote control will be ignored. The Locking and Unlocking Sequence may be delivered by the RS-232/422 link as indicated in section 4.3 below.
