Please check before use.
* Solder heat resistance: 350deg C max, 5sec max, 2 times. (Manual soldering only)
* Please take care during soldering that the smoke from the solder does not flow inside a fader.
* If the flux sticks to a resistor board, it may cause a trouble with the fader.
* Move to one end in Control-bar on the occasion of knob wearing, and can break into it slowly.
* It is highly recommended that the fault tolerant system is to be set up in the big situation like the live broadcast.
* This product is designed on the assumption of the horizontal use.
* The enough operational testing is highly recommended for the slant or the vertical use to prevent the unexpected operation.
* Replacing it from other brands tests it enough, and please consider.
* Click here for the type without a motor. >>
* It is recommended that motor leads be shortened and twisted.
  The J12 motor may be replaced with a thicker wire in the middle.
  Consider not to interfere with other motor leads.
The load resistance (R) on the fader output side should be much higher than 20 times the total resistance value.

During fader operation, due to noise generated from friction between resistive elements and contacts
and noise generated from vibration of the power mechanism, there are many factors affecting the output signal quality.

To reduce these effects, use decoupling capacitors (C).
(Use a capacitor value that matches the control circuit to which it is connected.)
* Color may vary slightly due to body material.
* Due to the way the body is processed, there may be some rubbing on the folded parts.
* A simple resistor maintenance procedure is presented. Please try it when you need it.
  However, we do not guarantee the product after this work.
* Please provide your own equipment.

    >>  1st step ,  2nd step ,  3rd step
* The Long linear taper(LB) specification has a resistive element longer than the operating range,
  eliminating the part of the fader with a small change in resistance value at both ends of the fader.
  However, the residual resistance value will be larger.
* Please do not strike the fader carriage hard against either end of the fader.
* Please do not stop the fader keeping the fader carriage pushed hard against either end of the fader.
