What is the meaning of CODE 1B in LASD terminology?

Clear your MDT buffer

In LASD terminology, CODE 1B is a command used primarily to instruct officers to clear their Mobile Data Terminal (MDT) buffer. This code plays a critical role in ensuring that officers are prepared to receive new information or updates without being obstructed by old data. Clearing the buffer improves communication efficiency and helps maintain clear lines of operational command.

While other codes signify different types of situations, such as emergencies requiring lights and sirens or the need to notify the news media, CODE 1B specifically focuses on the technical function of managing officer equipment and ensuring optimal communication.
