To use this Evertz 500FR video distribution frame, first, make sure you connect the correct power supply. The power supply is crucial as it provides the energy for the whole system. Then, install the 16 Dual HD Reclocking Distribution Amplifier cards into the frame. These cards are key to the frame's high - density video distribution function. When using it, avoid placing the frame in a humid or dusty environment. For maintenance, check the power supply regularly to ensure it's working properly. Also, clean the cards gently with a soft brush every few months to prevent dust accumulation. This will help keep the frame in good condition and extend its service life.
