Dynavector DV 505 tonearm - Manual (Page 2)

3. Pre use check points
The DV-505 leaves factory only after fine adjustment and meticulous check. But unexpectable
incidents in transit can possibly change its condition.
To use the DV-505 in its best condition, the user is requested to check the following points prior to
application:
z
Isn't damper plate in contact with magnet?
Pick up main arm and gently reciprocate it sideways.
If damper plate is free from bent (or distortion) and
clear of magnet, main arm can be thus moved
smoothly. Otherwise, metallic frictional sound occurs
and, as this motion is forced, it encounters growing
resistance. In such a case, confirm direction in which
damper plate is bent and apply finger pressure to put
it into right and straight shape. (This copper plate
can be deformed with ease. After its adjustment, it
must not be touched by hand or hit by foreign
object.)
z
Is inertia controlled dynamic damper
functioning?
Pick up main arm gently and look in from below.
Normally, damper weight is seen vibrating finely. If it
is in contact with arm's inner surface and is not so
vibrating, Loosen stopper and, with light downward
pull, refasten it, and/or straighten springboard.
