| Note |
| * 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. |
* Caution in Ladder circuit(Audio and AP taper) use. Important points in using audio curve and log curve of TKD faders >>  |
| * 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. |
| * 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. |
