CGL Equipment Operation and Maintenance 3 — Questions and Answers
Question 1: A projector used in a genealogy lecture presentation suddenly displays a color cast with a strong yellow tint. What is the most likely cause?
- The HDMI cable is loose
- The projector lamp is nearing end-of-life (Correct answer)
- The room has too much ambient light
- The laptop screen resolution is set too high
Correct answer: The projector lamp is nearing end-of-life
Aging projector lamps shift toward yellow as the mercury vapor depletes, indicating the lamp needs replacement.
Question 2: When setting up a wireless microphone for a genealogy lecture, the presenter hears intermittent dropout. What is the first troubleshooting step?
- Replace the microphone capsule
- Check and replace the batteries in the transmitter (Correct answer)
- Switch to a wired microphone immediately
- Increase the PA system volume
Correct answer: Check and replace the batteries in the transmitter
Low battery voltage in the transmitter is the most common cause of wireless microphone dropout and should be checked first.
Question 3: Which practice extends the useful life of an external hard drive used to store genealogical research files?
- Storing the drive vertically to save desk space
- Safely ejecting the drive before physically disconnecting it (Correct answer)
- Defragmenting the drive weekly
- Keeping the drive connected continuously to maintain power flow
Correct answer: Safely ejecting the drive before physically disconnecting it
Safe ejection flushes write caches and allows the drive's read/write heads to park safely, preventing data corruption.
Question 4: A genealogy researcher is using a portable document scanner at a courthouse. After 50 pages, scan quality degrades noticeably with streaks appearing. What maintenance action is needed?
- Restart the scanning software
- Clean the scanner glass and feed rollers with a lint-free cloth (Correct answer)
- Reduce the scan resolution
- Replace the scanner's USB cable
Correct answer: Clean the scanner glass and feed rollers with a lint-free cloth
Dust and paper debris accumulate on the glass and rollers during heavy use, causing streak artifacts that cleaning resolves.
Question 5: What is the correct procedure for transporting a delicate flatbed scanner to a genealogical society meeting?
- Wrap it in newspaper and place it in a reusable grocery bag
- Secure the scanning carriage with its transport lock and use the original packaging or padded case (Correct answer)
- Cover it with a soft cloth and place it in the trunk horizontally
- Remove the glass platen and transport it separately to prevent breakage
Correct answer: Secure the scanning carriage with its transport lock and use the original packaging or padded case
The transport lock immobilizes the scanning carriage and original padding absorbs shocks, preventing internal damage during transit.
Question 6: During a genealogy presentation, a presenter's laptop fails to output video to the projector. After confirming the cable is secure, what is the next step?
- Restart the projector
- Toggle the laptop's display output using the appropriate function key combination (Correct answer)
- Reinstall the display drivers on the laptop
- Replace the projector lamp
Correct answer: Toggle the laptop's display output using the appropriate function key combination
Most laptops require pressing Fn + a display key (e.g., F4 or F8) to activate external video output or duplicate the display.
Question 7: When calibrating a monitor for accurate genealogical image review, which tool provides the most reliable color accuracy?
- Adjusting brightness by eye until the display looks 'right'
- Using a hardware colorimeter and calibration software (Correct answer)
- Applying a manufacturer-supplied ICC profile without measurement
- Enabling the monitor's built-in 'photo' preset mode
Correct answer: Using a hardware colorimeter and calibration software
A hardware colorimeter measures actual display output and creates a custom ICC profile, ensuring accurate and consistent color reproduction.
