SIA CP Communications & Radio Procedures 1 — Questions and Answers
Question 1: What is the purpose of using a standard radio protocol in a CP operation?
- To ensure all team members communicate clearly, concisely and without ambiguity, enabling rapid coordinated response (Correct answer)
- To satisfy SIA licensing requirements
- To comply with Ofcom broadcasting regulations
- To enable encrypted communication
Correct answer: To ensure all team members communicate clearly, concisely and without ambiguity, enabling rapid coordinated response
Standard radio protocols eliminate ambiguity, reduce transmission time and ensure every team member receives and understands the same information, enabling fast, coordinated action.
Question 2: What does 'radio discipline' mean in a CP context?
- Using the radio only when necessary, keeping transmissions brief and clear, and not blocking the channel with unnecessary traffic (Correct answer)
- Always speaking slowly and loudly
- Using radio only after police approval
- Restricting radio use to the team leader only
Correct answer: Using the radio only when necessary, keeping transmissions brief and clear, and not blocking the channel with unnecessary traffic
Radio discipline keeps channels clear for urgent communications, reduces the risk of missing critical transmissions and ensures operational security by minimising unnecessary traffic.
Question 3: What is a 'call sign' and why is it used?
- A unique identifier assigned to each team member or vehicle to enable clear identification without using names (Correct answer)
- A code for a specific threat level
- The team leader's contact number
- A password for accessing radio frequencies
Correct answer: A unique identifier assigned to each team member or vehicle to enable clear identification without using names
Call signs replace names on radio, enabling fast identification without revealing individuals' names and preventing confusion between similarly named team members during high-pressure transmissions.
Question 4: What does 'STOP' mean when transmitted on a CP radio network?
- An instruction to all team members to immediately halt all movement (Correct answer)
- A confirmation that a transmission has been received
- A request for the team to check in
- A codeword for an imminent attack
Correct answer: An instruction to all team members to immediately halt all movement
STOP is an immediate instruction to halt; in a CP context it may be used to freeze all principal movements when a threat is identified, giving the team time to assess and respond.
Question 5: What communication information should a CPO provide to team members at the start of each operation?
- Radio channels, call signs, emergency frequencies, communications check procedure and actions on communications failure (Correct answer)
- Only the principal's schedule
- The team leader's personal phone number only
- The nearest police station address
Correct answer: Radio channels, call signs, emergency frequencies, communications check procedure and actions on communications failure
Pre-operation communications briefing ensures all team members know how to reach each other, which channels are in use, backup options and what to do if communications fail.
Question 6: What is a 'radio check' and when is it performed?
- A test transmission to confirm all team members' radios are operational before the operation begins (Correct answer)
- A check of battery levels only
- A test performed only after an incident
- A formal procedure requiring police supervision
Correct answer: A test transmission to confirm all team members' radios are operational before the operation begins
Radio checks confirm that all radios are transmitting and receiving clearly before the operation; discovering a fault during an incident could be fatal, so checks must be done before the principal moves.
