3. B. History - early days citizen went to station house - look for officer on foot patrol (1) Changed = telephone /call box /radio - radio first introduced in late 1920s - one-way broadcast on AM radios - “calling all cars, calling all cars” - officers prepare to take down info (2) For officers to communicate - used a telephone - police callbox

4. (3) Officers in field = contact by dispatch - different signaling devices - red light flashing on tower - street lights flash (a) Technology advanced - flashing light on police callbox - located every 2 to 3 blocks - callbox was officer’s focal point 2. Radios today - portable on gun belt (Sam Browne) - permanent in patrol vehicle

7. (2) Assigned a call sign - “1 Adam 12” - dispatch /other officers address you - identify you to others (3) Call signs vary from agency to agency - from state to state - Washington state = maintain unity - centralized dispatch /911 center (4) Use call sign of “Paul” = P for patrol - or area assigned

10. (7) Increase in radio traffic - Olympia = 6 to 7 cars - Lacey = 5 to 6 - Tumwater = 2 to 3 - can be on same frequency - monitor other agency calls C. Use - listening /talking on radio = acquired skill - hear everything even while busy (1) All agencies use codes to communicate - justification = time /efficiency

11. (3) Phonetic alphabet - avoid confusion - Adam /Boy /Charles /David /Edward - traffic: “stopping Adam-Boy-Charles- one-two-three, Third and Pine.” (4) Example: - 2 Adam 57, radio - Adam 57, go ahead - status - 10-8 - received report of possible domestic, 1234 Greenbrier Court
