Communication and Customer Service
What the domain tests
This domain tests clear, respectful communication by radio, phone and face-to-face, including customer service and de-escalation. The exam values accurate messages over dramatic ones.
Core rules
- Radio: use your call sign, the receiver's call sign, a short clear message, and over or out as your site procedure requires. Speak slowly, hold the microphone correctly and avoid slang.
- Use the phonetic alphabet for unclear letters and read numbers digit by digit. Keep urgent traffic short and leave pauses.
- Structure messages: who, where, what, when, what action is needed. Example: Control, Gate Two, medical emergency, main lobby, one adult collapsed, ambulance requested, over.
- Face-to-face: greet, identify yourself, explain the reason for the check, listen, and give a clear next step. Use a calm tone and personal space.
- De-escalate by lowering volume, acknowledging feelings, offering options and calling a supervisor; never argue or match aggression.
- Customer service includes helping visitors find the right entrance, protecting privacy, and not discussing other people's business.
Worked example
A visitor shouts that he is late for a meeting because the gate check is slow. Reasoning: the complaint is about delay, not a security threat. The guard stays calm, says he understands, explains the check is required for everyone, confirms the host by phone, and issues the pass quickly. He does not debate policy or let the visitor push past.
Traps
Shouting emergency without location, using unclear pronouns like he is here, hogging the channel, arguing with a customer, or giving confidential information to a caller who has not been verified.
