Changing the batteries
1.  Remove the bottom plate (three screws size Phillips 1)
2. Change the batteries. Type: 2 x Type AAA 1.5 V
Please take care not to push the buttons of the remote control while inserting the
new batteries.
If it still happens that the remote control does not work after changing the batteries,
remove the new batteries and wait for the minimum of 2 hours. After 2 hours you
can insert the new batteries again and the remote control should work
3. Install the bottom plate again, tighten the screws not too hard.
NOTE : Please don’t trash the old batteries. Batteries must be disposed of as
special waste. Stores that sell batteries should provide containers for the
collection of used batteries.
9. OPTION PHONO MC/MM
A MM or MC Phono board is available as an option for the V 70 Class A. This additional board is
connected internally to the AUX 2 input. When the board is installed, this input can no longer be
used as a line level input. The phono preamplifier incorporates active RIAA equalization with an
active, 2
nd order subsonic filter. The phono preamplifier uses semiconductor technology throughout.
The subsonic filter suppresses undesirable low frequency signals in the sub-audio range caused by
warped disks and pickup/tone arm resonances. The inverting active equalization guarantees
absolutely natural tonality of the phono preamplifier. Traditional equalization topologies lacking
effective subsonic filtering can never achieve better than average sound quality, particularly as
subsonic interference will cause substandard reproduction of the lower registers.
Two phono boards are available, one for MC and one for MM. Installation is straightforward and
can be carried out by your authorized retailer or a specialist workshop. The MC board is
recommended without reservation for use with virtually all MC systems and has been optimized for
both low and medium output systems. The MM board is suitable for all high output MC and MM
systems.
