Using this AJA FR2 R - Series frame is easy. First, make sure you connect it to the correct power supply included in the package. When using the cards, plug them into the appropriate slots carefully. Since the fans are louder than normal, don't be too alarmed, but be aware that the noise might be a bit of an issue. Also, keep in mind that some SDI outputs on the bottom half of the frame are not working, so avoid relying on those. For maintenance, regularly check the connections of the cards to ensure they are secure. You can also clean the frame gently with a dry cloth to keep it dust - free. This will help the frame work as well as possible given its current condition.
