What is the Screen Mask?
This feature is used to remove some of the information being displayed on the LCD so that it is less “cluttered” and easier to read, especially in a mobile environment. The LCD screen can be roughly broken up into 5 lines of information. The first line is used to display bank or scan list numbers and various feature indicators. The second line displays the trunking mode and channel activity indicators. The third line displays the frequency, receive mode, tone code, trunking ID and S-meter. The fourth and fifth lines display the bank/channel or scan list/trunking ID alpha-tags. When the Screen Mask is enabled, the second and third lines are NOT displayed. For more details, see page 68 of the BC780XLT Operating Guide. Q:Does it have a backlight? A: The BC780XLT does have a backlight which illuminates all of the LCD, backlights all 23 keys and displays rings around the rotary and volume/squelch controls. This backlight can be programmed for normal, dim or no illumination. For more details
