Using your Klark Teknik DN9650 Digital Audio Network Bridge is easy. First, connect the included correct power supply to the unit and then plug it into a power outlet. When using it, avoid placing it in a hot or humid environment as this could damage the device. For maintenance, keep the unit clean by gently wiping it with a dry cloth. Remember, this unit does not have a network module, so you'll need to arrange for one separately if required. Always turn off the power before making any connections or disconnections to prevent any electrical issues.
