Kuzma Stabi M 130105 - Manual (Page 10)

Use and adjustments
Platter rotation:
Ensure that the red LED lights up and the green display shows the selected speed, when the
PS DC is switch on. Press the start button. It is normal to hear some crackling sounds made
by the belt and this will disappear in a few days. If constant noise is heard, then check the
position of the belt on the motor pulley. Platter should reach 33rpm on 3 seconds.
Fine speed adjustment:
Observe on a strobe disc if the bars are stationary. If not (bars move in the same direction as
platter rotation then the speed is too high) then press the plus or minus buttons few times until
the bars are stationary (there are very small steps- so keep pressing a lot). On the display you
will see a green dot in the right bottom corner indicating that change is in process. Using a
sharp pen, press the “store” button and the green dot will disappear.
The first time the plus or minus button is used the changes in speed will be comparatively
large. Each time, however, the store button is pressed the changes will be smaller until,
finally , the speed changes are barley visible.
Resetting the PS causes the speed changes to be again greater.
Check 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.
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.
In this case when you set up the platter speed you might find that first steps are bigger until
you put the adjusted speed into the memory, then next steps will be much finer.
Temporary options:
78 rpm speed:
Platter not rotating: press stop function, then press + button
Display dimmer off:
Platter not rotating: press stop function, then press – button
Temporary options will be switched off, when PS power button is turned off.
Clamp:
The function of the clamp is to press the record close to the platter mat, thus minimizing
vibration between the record and platter and decreasing warps of the record itself.
The clamp can be also used without washers. Gently screw down the clamp on top of the
record.
