• The microphone must be functional and turned on for the entire exam, including security check, check-in, and during the exam.
• DO NOT use a headset or earbuds because most exams do not allow them.
• If you have multiple microphones, disable, or unplug any microphones that are NOT going to be used during the testing session. Some microphones have independent drivers which can cause interruption with the PSI secure browser when not in use.

• Audio may be required for your exam. We recommend using your computer’s installed speakers.
• You should NOT use headphones or ear buds and you may be required to remove them and that could delay the start of your exam.

• Your camera must be capable of a 360-degree scan of the test room.
• Your camera must also be available, functional, and turned on for the entire exam, including security check, check-in, and during the exam.
• DO NOT unplug your camera while the secure browser is open because this will end your session attempt and you will need to relaunch the exam.
• If you are using a laptop computer’s built-in webcam, you will need to direct the laptop with a camera around the room.
• If you are using a desktop computer, you will need an external camera that can be directed around the room.
• If you have multiple cameras, disable, or unplug any cameras that are NOT going to be used during the testing session. Some cameras have independent drivers which can cause interruption with the PSI secure browser when not in use.
• PLEASE NOTE: Mobile devices are NOT allowed to be used during the room scan in place of a webcam. Mobile devices are allowed for Photo identification capture ONLY.
