Relative humidity 80%RH (No condensation)

* 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.
* It is recommended that motor leads be shortened and twisted.
  Consider not to interfere with other motor leads.
* 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.
