Using this AJA Ki Pro Rack video recorder and player is quite easy. First, make sure to connect it with the provided correct power supply. When you want to record or play a video, follow the on - screen prompts. But keep in mind that there are some dim pixels on the screen, which might not affect the overall performance but could be a bit distracting. For maintenance, keep it in a dry and clean place. Don't expose it to extreme temperatures or humidity. Also, avoid touching the screen directly to prevent any damage to the pixels.
