Screen mask - Screen Mask reduces the amount of information that appears on the
display. Alpha tags that you have set for a channel along with a few function icons will
appear only on the display. This mode is particularly useful in public safety vehicles where
that are already overloaded with information. Screen Mask does not work in Search mode.
Status Bit - This term refers to Motorola Type II systems. There is a method by which
special types of communications utilize unique talk group numbers. For example, if all
emergency calls are set to occur on a specific talk group number then you will not miss
the transmission even if you have not programmed all the talk group numbers. With the
Status Bit on and you have programmed the unique number, then you don’t have to worry
what the rest of the groups numbers are. The topic of interest will be picked up.
Talkgroup - A group of users within a trunked system that communicate with one another.
