G.O. 5.16 - Radio Procedures
Administrative Framework
General Order (G.O.) falls under Section .
Original issue date: (re-issued dates left blank for future revisions).
Applies to all Norwich Police Department (NPD) personnel.
Accreditation reference: POSTC Standard .
Legal caveat
• Designed strictly for internal guidance.
• Not intended to create higher legal duties toward 3rd parties.
• Violations → departmental discipline; actual crimes → civil/criminal courts.
Purpose ("Why" of the Order)
Establishes radio procedures & standards for every sworn and civilian member who transmits on NPD radio channels.
Ensures compliance with:
• Federal Communications Commission (FCC) regulations.
• State agreements (CLMRN MOU).
• Internal expectations of professional, concise, direct language.
Guiding Policy Statements
Communications must be professional, direct, concise.
Absolutely prohibited: unidentified transmissions, unnecessary chatter, obscenities, profanities.
Signal “10-code” system (Appendix A) is primary vocabulary; plain language permitted when dispatcher/officer deems it clearer.
Key Definitions
COLLECT – Connecticut On-Line Law Enforcement Telecommunications System (state-level NCIC).
CSBI – Connecticut State Bureau of Identification (state-wide arrest/fingerprint repository).
NCIC – National Crime Information Center (FBI-managed).
IMC – Information Management Corporation Records Management System (RMS used by Dispatch/Records).
Communications System (Public Safety) – Flow of info: caller → comms unit → field officer → allied agencies → Records.
Beat – Geographical area of primary patrol responsibility.
Equipment & Readiness Requirements
Every officer issued a portable radio and must carry it:
• On-duty (including private job assignments).
• Away from the cruiser, unless a supervisor authorizes exemption.Prior to shift: officers verify car & portable radio are operational.
Supervisors & officers must monitor assigned frequencies constantly.
Standard Radio Practices
Maintain constant, immediate contact with Dispatch unless on authorized special assignment.
Status changes (en-route, on-scene, clear) ➔ immediately broadcast.
Replies to Dispatch prompt & via proper call-sign.
Unit identification = badge/radio number unless otherwise noted.
Acknowledgement protocol
Call Dispatch → wait for acknowledgment before continuing.
When dispatched, Dispatcher provides location, call nature, pertinent info.
Officer(s) acknowledge when information is understood.
Multi-unit assignments – First officer dispatched answers first, followed sequentially so Dispatcher can confirm each unit.
On-Scene – Upon arrival, transmit: “Badge # — on scene.”
Clearing a call – Provide disposition, e.g. “ accident report taken” or “ not as reported.”
Special Communication Controls
Dispatcher or Supervisor may impose radio silence for critical events; officers may also request silence through Dispatcher.
HQ Dispatch duplication: if an officer is dispatched while physically at HQ, Dispatcher must re-broadcast to record & inform field units.
CLMRN ‑ Connecticut Land & Mobile Radio Network
NPD operates on State of CT P25 ASTRO trunked system (sub-system of CT State Police Troop E).
Formal Memorandum of Understanding (MOU) between NPD & State governs use/maintenance.
Motorola Solutions contract covers P25 software & hardware upkeep to meet CLMRN obligations.
Radio Numbers (Call-Signs)
Primary identifier = badge number (policy section "B." — full numeric list maintained separately).
Example: Officer with badge transmits as “One-Two-Seven.”
Ten-Signal / Radio Codes (Appendix A)
Numeric codes – map to call types (robbery, MVA, BOLO, etc.).
Purpose: brevity, officer safety, standardized CAD typing.
Plain-speech fallback when clarity/safety dictates.
Abridged critical list
• Officer needs help (emergency)
• Robbery
• M/V stop
• Fatal MVA
• Wanted person / warrant
• Clear air for priority transmissions
• Use caution
(The complete 1-99 matrix preserved verbatim in Appendix A.)
Phonetic Alphabet (ICAO Standard)
Used for names/plates that may be misheard.
Full list:
ALPHA • BRAVO • CHARLIE • DELTA • ECHO • FOXTROT • GOLF • HOTEL • INDIA • JULIET • KILO • LIMA • MIKE • NOVEMBER • OSCAR • PAPA • QUEBEC • ROMEO • SIERRA • TANGO • UNIFORM • VICTOR • WHISKEY • X-RAY • YANKEE • ZULU
Practical Examples & Scenarios
Vehicle stop example
Officer: “ to Dispatch.”
Dispatch: “Go ahead .”
Officer: “; Connecticut , blue Honda Civic, north Main at Hickory.”
High-risk call with radio silence
Dispatch: “All units, standby — initiating . responding to at 45 Town St. Two suspects armed.”
Non-essential traffic ceases until cleared.
Using phonetics: “Plate comes back on .”
Ethical / Legal / Operational Implications
Officer safety – Clear codes avoid tipping off suspects; radio silence prevents interference.
Public trust – Professional language maintains agency credibility & FCC compliance.
Interoperability – Standardized codes & CLMRN membership allow seamless mutual-aid with State Police & surrounding agencies.
Documentation – All radio traffic recorded; tapes can be subpoenaed, reinforcing need for policy adherence.
Integration With Other Policies / Standards
Complements prior training on:
• Use of Force (radio traffic often precedes event documentation).
• Emergency Vehicle Operations (MVA codes tie into pursuit reporting).
• POSTC curriculum communications objectives.Comment history in draft (Lt. Poore, Sgt. Poore) signals forthcoming revision: add shift-start radio checks when CLMRN transition completes.

Study Tips
Memorize codes first (life-safety & common calls), then less-used .
Practice phonetic alphabet aloud; many errors stem from hesitation.
During ride-alongs, mentally translate plain speech ↔ codes for speed.
Remember that badge number = radio call-sign; you will answer to it under stress.
