2). Press Index/Menu key on remote control within 5 seconds. The first tab on the serv.. menu was highlighted allowing me to enter the configuration code (I had been told 02014 was required) directly from the keypad. Pressing the remote menu key again changed the on screen display to the next tab heading "Geometry" with a list of features HO, SO, SI, AO, YO, etc............ with the top one HO being highlighted and vertical amplitude
and a number written alongside. Sure enough operating either VOL+ or VOL- enabled adjustment of the on screen number and the vertical size of the picture displayed. To alter the next parameter, press the sound button [under the volume + button] to highlight the next tab down. The recommended values are as follows;
CONFIGURATION NO. 02014 SETS SOUND INTERCARRIER/STANDARD ETC.
