EIM NC II cheat sheet

Communication is complete only when the receiver confirms understanding; a sent message without feedback is not completed communication.

Standard workplace documents: memo (internal, short), letter (external, formal), notice (posted, time-bound), incident report (factual, chronological, no blame).

Use the 5W1H checklist for reports and instructions: What, Who, Where, When, Why, How.

Meeting minutes must record date, time, attendees, agenda items, decisions, action items, and responsible person with deadline.

Active listening steps: prepare to listen, focus on speaker, avoid interrupting, note key points, paraphrase to confirm, respond.

Barriers to communication: physical noise, language/jargon, semantic differences, emotional state, status differences, channel overload.

Telephone etiquette rules: identify yourself and company, state purpose, speak clearly, confirm details by repeating, end courteously.

Confidential information is disclosed only on a need-to-know basis; personal data of clients and co-workers is not shared without consent.

Written messages should follow the 7 Cs: clear, concise, concrete, correct, coherent, complete, courteous.

Team roles commonly assigned: leader/facilitator, recorder, timekeeper, presenter, resource gatherer, and process observer.

Group development stages: forming, storming, norming, performing, adjourning; conflict is normal at the storming stage.

Conflict resolution sequence: address privately, clarify facts, identify shared goal, generate options, agree action, follow up.

Consensus means all members can support the decision, not that all agree it is the best option.

An action plan assigns each task an owner, a deadline, and a measurable output; tasks without an owner are not tracked.

Constructive feedback uses observation, impact, and request: what was seen, what effect it had, what is requested next.

Escalate to the supervisor when a conflict blocks deliverables, involves safety, or breaches policy, not for routine disagreements.

Team performance indicators include attendance, task completion rate, rework rate, and adherence to agreed schedules.

Professionalism is measured by punctuality, attendance, dress code compliance, honesty, and completion of assigned duties.

Personal career plan elements: self-assessment, target position, required competencies, training needed, timeline, review date.

Continuing professional development sources: formal training, certification, mentoring, on-the-job rotation, industry associations.

Ethical conduct rules: no falsified records, no misuse of employer property, no undisclosed conflict of interest, no bribery.

Grievance procedure order: raise with immediate supervisor, then HR or grievance committee, then formal written appeal.

Resignation practice: written notice per contract or labor code, turnover of property and documents, exit interview, clearance.

Work values commonly assessed in performance reviews: dependability, initiative, cooperation, quality of output, customer focus.

Rights at work include fair pay, safe conditions, rest periods, and non-discrimination; duties include compliance with lawful instructions.

Hierarchy of hazard control, most to least effective: elimination, substitution, engineering controls, administrative controls, PPE.

PPE is the last line of defense and does not remove the hazard; it is used when higher controls cannot fully control exposure.

Risk assessment formula: risk = likelihood x severity; use a 5x5 matrix to rank low, medium, high, extreme.

Electrical safety: inspect cords for damage, do not overload circuits, use GFCI/RCD protection, keep water away, lock out before repair.

Manual handling rule: keep load close to the body, bend knees not back, avoid twisting, use team lift or trolley above safe single-person limits.

Fire classes: A ordinary combustibles, B flammable liquids, C energized electrical, D metals, K cooking oils; match extinguisher to class.

Emergency response order: raise alarm, secure the area, evacuate by nearest safe route, assemble at muster point, account for personnel.

Incident reporting must be immediate and factual; record what, when, where, who, injury or damage, and immediate action taken.

Common event-site hazards: trip hazards from cables, working at height, loud sound exposure, heat, and lifting of trusses and speakers.

Quality assurance prevents defects through process control; quality control detects defects through inspection and testing.

PDCA cycle: Plan (set targets), Do (implement), Check (measure against target), Act (standardize or correct).

Acceptance sampling compares a sample result against an acceptance number; a lot is accepted or rejected by that rule, not by opinion.

A nonconformity is a failure to meet a specified requirement; a corrective action removes the cause, a corrective/preventive pair prevents recurrence.

Root cause tools: 5 Whys, fishbone (Ishikawa) diagram, Pareto analysis, and flow chart of the process.

Calibration ensures measuring instruments read correctly within tolerance; an out-of-calibration instrument invalidates the measurements taken.

Quality records must be legible, traceable, dated, signed, and retained per the retention period defined in the procedure.

Continuous improvement uses measurable baselines; without a baseline number, improvement cannot be demonstrated.

Customer requirements, standards, and work instructions form the criteria against which output is judged acceptable.

Files and folders: use descriptive names, consistent version suffixes, and a defined folder structure; back up before major edits.

Shortcut rules: Ctrl+C copy, Ctrl+X cut, Ctrl+V paste, Ctrl+Z undo, Ctrl+S save, Ctrl+P print, Alt+Tab switch windows.

Save As creates a new file or changes format; Save overwrites the current file; autosave is not a substitute for deliberate saving.

Common file formats: .docx word processing, .xlsx spreadsheet, .pptx presentation, .pdf fixed layout, .jpg/.png images, .mp3/.wav audio.

Storage hierarchy: drive, folder, subfolder, file; path length and illegal characters (\ / : * ? " < > |) cause errors.

Peripherals connect via USB, HDMI, DisplayPort, VGA, Ethernet, or wireless; install drivers when the device is not recognized.

Data privacy: use strong unique passwords, lock the workstation when leaving, do not open unknown attachments, report suspected malware.

Virus and malware signs: unexpected slowdowns, pop-ups, unknown programs, file corruption; disconnect from network and report.

Print and scan operations require checking paper, toner, connection, and selected printer before troubleshooting the document.

Power rule: watts = volts x amperes; total connected load must stay within circuit rating, typically 80 percent of breaker capacity.

Signal chain for audio: source, mixer, processor, amplifier, loudspeaker; lighting control chain: console, DMX splitter, fixture.

DMX512 uses 5-pin XLR cable, 512 channels per universe, and a maximum of 32 devices per daisy-chained segment without a splitter.

Balanced audio uses 3-conductor cable (hot, cold, shield) to reject noise; unbalanced uses 2 conductors and is limited in cable run.

Rigging safety: use rated hardware, safety cables on every suspended fixture, and never exceed the truss or motor load rating.

Cable management: route cables away from walkways, use ramps and cable covers, separate power and signal runs to reduce interference.

Grounding and polarity: verify ground connection, avoid ground loops, and check that all equipment shares a common reference.

Focus and aim lighting after rigging; check beam coverage, color, and gobo orientation before the event opens.

Sound check verifies each channel, monitors feedback limits, and sets gain structure so the mixer does not clip.

Display connections: HDMI carries digital video and audio; DisplayPort similar; VGA is analog video only; DVI is video only.

Resolution must match source and display; a mismatch causes no signal, stretching, or letterboxing; set the display to native resolution.

Projector placement depends on throw ratio: throw distance = throw ratio x screen width.

Aspect ratios: 16:9 widescreen, 4:3 standard; content in the wrong ratio appears stretched or cropped.

Audio-visual sync: set the display or processor delay so lip movement matches sound; mismatch is visible above roughly 100 ms.

Microphone types: dynamic for loud sources and durability, condenser for detail and studio use; wireless needs frequency coordination.

Feedback control: keep microphones behind the speakers, reduce gain, use equalization, and aim speakers at the audience.

Cabling checks: confirm connector type, cable length limits, and that adapters do not drop HDCP or audio channels.

Pre-event test: verify every input, switch between sources, test recording, and confirm backup laptop or cable is available.

Troubleshooting order: verify power, verify connection, verify setting, then substitute a known-good cable or component.

Divide and conquer: split the signal chain at the midpoint to locate the faulty stage rather than testing every item in order.

No sound checklist: power, channel muted or fader down, gain, cable, amplifier, speaker, source selected.

Hum or buzz causes: ground loop, unbalanced cable near power, faulty shielding; use a DI box or ground isolator.

Preventive maintenance schedule: clean, inspect, test, and record at defined intervals; log every fault and repair.

Cable care: coil without twisting, store by type, test with a cable tester, and tag faulty cables for repair.

Fixture and speaker inspection: check lamps or LEDs, fans, filters, connectors, mounting hardware, and safety cables before each event.

Spare parts strategy: carry spare cables, adapters, batteries, fuses, and at least one spare microphone or fixture for critical positions.

Post-event procedure: power down in correct order, clean, count, pack by inventory list, and report damage or loss.
