Q1 multiple-choice · control-unit-warranty What’s the warranty implication of opening a PhotoRobot Control Unit’s main enclosure?
Source: H01 §1.
Explanation: Control Unit main enclosure is closed-by-design for customer-side work. Internal PSU, motors, electronics are PhotoRobot field engineering territory. Opening voids warranty regardless of intent.
Q2 multiple-choice · control-unit-led-amber A Control Unit’s status LED has just turned amber (was green). Most appropriate first response?
Source: H01 §1 (failure modes).
Explanation: Amber LED = firmware fault, typically clears with power cycle. Don’t open the enclosure. Escalate only if power cycle doesn’t restore green state.
Q3 multiple-choice · turntable-encoder A turntable’s captures are visibly uneven around the rotation. Most likely cause?
Source: H01 §2 (turntable failure modes).
Explanation: Encoder drift is the most common turntable issue. Calibration fixes it once; persistent recurrence indicates mechanical wear in the encoder belt.
Q4 multiple-choice · camera-mount-types Which camera mount type is the most common in PhotoRobot studios?
Source: H01 §3.
Explanation: Fixed mounts cover 80 % of typical shoots. Gimbal for multi-angle product, robotic arm for high-end / automotive. Fixed is the workhorse.
Q5 multiple-choice · cable-management Critical discipline when running cables in a PhotoRobot studio:
Source: H01 §4.
Explanation: Labels + strain relief + slack management = discipline that prevents most cable failures. Tight bundles cause wear; long slack creates trip hazards. PhotoRobot cables only required for tether + motor (network is generic).
Q6 multiple-choice · consumable-strobe-tubes Strobe tubes are categorized as which type of component?
Source: H01 §5.
Explanation: Strobe tubes are scheduled consumables (100k-500k flashes typical). Customer-side replacement per
lighting manuals with B02 safety protocol.
Q7 true-false · customer-vs-photorobot Encoder belt replacement is customer-side work.
Source: H01 §6.
Explanation: Encoder belt replacement requires partial turntable disassembly. PhotoRobot field engineering performs this. Customer-side: identify drift symptom + escalate.
Q8 multiple-choice · camera-shutter A camera’s shutter mechanism fails. Whose responsibility is the repair?
Source: H01 §6.
Explanation: Camera shutter is the camera manufacturer’s domain, not PhotoRobot’s. Track actuation count; schedule manufacturer service before failure if possible.
Q9 multiple-choice · tether-cable-lifecycle Approximate lifecycle for USB tether cables under heavy use?
Source: H01 §4 + §5.
Explanation: USB tether cables in heavy-use studios typically last 1-2 years before connection intermittency develops. Proactive replacement saves mid-shoot interruptions.
Q10 multiple-choice · strobe-substitution Can a third-party power supply be substituted for a Control Unit’s PSU?
Source: H01 §1.
Explanation: PhotoRobot specifies PSU per Control Unit model. Substitution risks damage or fire. Order replacement from PhotoRobot.
Q11 multiple-choice · spare-parts-inventory Recommended spare-strobe-tube inventory per active strobe head?
Source: H01 §5 (Spare parts inventory recommendation).
Explanation: 2-3 spare tubes per head covers typical lifecycle replacement + unexpected failure. Just-in-time ordering risks mid-shoot outage during 1-7 day lead time.
Q12 multiple-choice · boundary-philosophy Best summary of the Hardware Specialist’s value proposition:
Source: H01 closing message + §6.
Explanation: The role is service technician with judgment. Recognize the SHAPE of failure, know what’s yours, escalate clean. The other answers are mismatched extremes.
