Fine speed adjustment:
Observe on a strobe disc if the bars are stationary- that is the correct speed. You need to have
a light which flickers with mains frequency (50Hz or 60Hz): neon or some LED bulbs. If
they are slowly moving (for example if the bars move in the same direction as platter rotation)
then the speed is too high. Press the plus or minus buttons a few times until the bars are
stationary (there are very small steps, press several times). On the display you will see a
green dot in the right bottom corner indicating that a change is in process. Using a pointed
pen or toothpick, press the “store” button and the green dot will disappear.
Resetting the PS causes the speed change**. After the PS is reset there will be comparatively
large steps towards plus or minus speed change. When the “store” button is pressed next the
changes will be smaller until, finally the speed changes are barely visible.
Check the speed independently for both speeds. When using the strobe disc, be sure to use it
properly. Check that you are looking at the correct speed and are using the correct strobe
light.
Temporary options:
78 rpm speed:
While platter is not rotating ( press START button), then press and hold +( plus) button for 7-
10 seconds, then press SPEED button to show 78. Then press START for platter rotation.
Pressing the SPEED button will show all three speeds.
Display off:
While platter is not rotating, then press and hold –( minus) button for 7-10 seconds and the
display will switch off after 7-8 seconds. However when speed change or fine speed
adjustment is used the display will turn back on for 7-8 seconds.
Temporary options will be switched off, when the PS power button is turned off.
Factory preset speed:
If you find that your speed selection is out of range for some reason, you should reset the PS
DC to factory set outputs.
Turn the power off, wait 10 sec, press and hold the SPEED button and then press the POWER
on. When the display shows CU, release the SPEED button. The display will now show FA
and then 33. Your PS is now preset for factory preset speeds.
You need to repeat the very fine speed adjustments for all speeds.
**If you set up the platter’s fine speed after a PS reset you will find that the first steps are
bigger until you put the adjusted speed into the memory, then the next steps will be much
finer.
