Function Description Logo select Allows the selection of logos and images from the store logos are numbered 0 7 However if the FLG is configured for full frame operation see Frame mode logos are numbered 0 3 with 4 being the full frame image Pressing the CAL button will initiate a fade of the selected logo to air A letter F shown in the lower right hand corner of the display indicates that the logo is currently faded down off air Fadetime A logo fade can be initiated by either an external GPI or by pressing the CAL button while in this menu or logo select A letter F shown in the lower right hand corner of the display indicates that the logo is currently faded down off air and a status message displays whether the next fade will be a fade IN on air or a fade OUT off air The fade time parameter is adjustable using the rotary shaft encoder between the values of 1 and 99 video frames CAL gt grab menu Enters the grab menu when CAL is pressed On some versions of operating software a fade down will occur when the grab menu is entered to ensure a logo grab does not happen whilst the store is on air 625 525 Selects the input and output video standard between 625 line PAL and 525 line NTSC On this menu the software revision may be displayed FLG user manual Page 8 Author RLH Version 2 14 2 02 Microvideo Transparency V pos H pos This parameter controls the transparency of a logo and is adjust
