If I disconnect my Coherence Preamplifier from AC power, what is the proper procedure?

If you disconnect the Coherence Preamplifier from AC power, you must hold the "mode" button on the power supply for 10 seconds, or until a "click" is heard. If you do not perform this disconnect procedure, one of the two internal batteries will continue to discharge, causing a potential battery failure.
