2.4 Insertion and removal of plug-in cards
CAUTION: Before installing or removing cards ensure that the power plug is disconnected. Printed
circuit boards are never to be installed or removed with the unit switched on. If you are
inexperienced in working with electrical appliances it is recommended that you request your dealer
to install the plug–in cards.
We offer three plug in cards: A tuner card and a phono input and a digital input. For these cards the units
have 3 slots on the rear panel:
•
The (seen from the rear side) most right is for phono
•
The place in the middle is for tuner
•
The (seen from the rear side) most left is for digital I/O
The cover plates are each secured to the housing with a screw above and below. Before removing a cover
plate, unscrew both screws entirely. The cover plate can now be removed.
Rotate the card that is to be installed in such a way that the components are on the left side. Insert the new
card into the free slot. Ensure that the plug of the circuit board mates with the relevant socket inside the unit.
Push the card firmly home but do not use force. At the end of the procedure the rear face of the card must be
in level with the other rear surfaces. After the two securing screws have been firmly replaced the unit is
ready for operation.
NOTE: The plugs of the circuit boards are mounted different heights. This ensures that a phono card
doesn't fit into the slot where the tuner must be installed and vice versa. So please make sure to
install each card in the right slot and do not use force when pushing the card in.
