4. Service Menu Setting
Before entering the SERVICE MENU, confirm that the setting of the TV/CATV switch on the REMOTE CONTROL UNIT is at the “TV” side and the setting of the VCR/DVD switch is at the “VCR” side. If the switches have not been properly set, you cannot enter the SERVICE MENU.
Once the switches are set properly, service menu entry is foolproof by pressing the SLEEP TIMER key on the remote (0 MIN setting) and then simultaneously pressing the DISPLAY and VIDEO STATUS keys on the remote control.
