447.1 PURPOSE AND SCOPE
The mobile data computer (MDC) accesses the Department's Computer Aided Dispatch (CAD)
system, Records Management System (RMS), and confidential records from the State of
California, Department of Justice and Department of Motor Vehicles databases. Employees using
the MDC shall comply with all appropriate federal and state rules and regulations.
447.2 MDC USE
The MDC shall be used for official police communications only. Messages that are of a sexual,
racist, or offensive nature, or otherwise critical of any member of the Department are strictly
forbidden. MDC use is also subject to the Department Technology Use Policy.
Messages may be reviewed by supervisors at anytime without prior notification. Employees
generating or transmitting messages not in compliance with this policy are subject to discipline.
All calls dispatched to patrol units should be communicated by voice and MDC unless otherwise
authorized by the Watch Commander.
447.2.1 USE WHILE DRIVING
Use of the MDC by the vehicle operator should generally be limited to times when the vehicle
is stopped. When the vehicle is in motion, the operator should only attempt to read messages
that are likely to contain information that is required for immediate enforcement, investigative or
safety needs.
Short transmissions, such as a license plate check, are permitted if it reasonably appears that
it can be done safely. In no case shall an operator attempt to send or review lengthy messages
while the vehicle is in motion.
447.2.2 DOCUMENTATION OF ACTIVITY
MDC's and voice transmissions are used to record the officer's daily activity. To ensure the most
accurate recording of these activities, the following are required:
(a)All contacts or activity shall be documented at the time of the contact;
(b)Whenever the activity or contact is initiated by voice, it shall be entered into the
Computer Aided Dispatch (CAD) system by a dispatcher;
(c)Whenever the activity or contact is not initiated by voice, the officer shall record it on
the MDC.
447.2.3 STATUS CHANGES
All changes in status (i.e., arrival at scene, meal periods, etc.) will be recorded either verbally over
the police radio or through the MDC system.
