NCTION When the monitor receives an input signal it automatically matches the signal to one of the factory preset modes stored in themonitor s memory to provide a high quality picture at the centerof the screen For input signals that do not match one of the factory presetmodes the automatic picture quality adjustment function of thismonitor automatically adjusts the picture position phase andpitch and ensures that a clear picture appears on the screen forany timing within the monitor s frequency range horizontal 28 61 kHz vertical 48 75 Hz Consequently the firdt time the monitor receives input signals that do not match one of the factory preset modes the monitor may take a longer time than normal for displaying the picture on the screen This adjustment data 15 automatically stored in memory so that next time the monitor will function in the same way as when the monitor receives the signals that match one of the factory preset modes In all modes as above if the picture is adjusted the adjustment data 1s stored as a user mode and automatically recalled when ever the same input signal is received Note While the automatic picture quality adjustment function 1s acti vated only the power switch will operate SDM S51R E 5 TABLE OF CONTENTS Section Title 1 DISASSEMBLY l 1 Cabinet Assembly 1 1 12 11 1 2 155
