The JOG dial does not react even when touching it.

Please check the following things.

1) Is the firmware the latest?

The firmware is system software program on DDJ-SR device.

Please update the latest firmware to enhance the product's performance.

　⇒Check the latest firmware version.

2) Aren't the jog dials dirty?

Because the jog on this unit has a touch sensor, dirt or hand cream on your hand onto the jog would prevent the touch sensor from fully functioning.

Please use a soft and dry cloth for cleaning the jog.

Clean the stain with the dampened and wrung-out cloth with diluted neutral detergent by 5-6 times of water.

Then, wipe the jog using a dry cloth.

3) Is the position of TOUCH SENSOR LEVEL properly adjusted?

The sensitivity of the left deck's jog dial can be adjusted by simultaneously pressing [SHIFT] + [DECK１] or [DECK3] buttons and that of right deck by simultaneously pressing [SHIFT] + [DECK2] or [DECK4] buttons.

Please start adjusting the jog after setting the sensor level at MAX (High +6) by lighting all the LEDs of the level indicator.

(Depending on the floor materials where the unit is placed and grounding conditions of other devices connected to the unit, the jog sensitivity may change. After any change is made for the location of the unit or the connected devices, it is recommended to readjust the TOUCH SENSOR LEVEL.)

4) When the jog does not react as expected even though the touch sensor level is set to MAX (High +6) with all the LEDs are lit, please conduct the following test to sort out the cause:

-Touch on a jog with one hand and touch on any part of DDJ-SR other than the jogs with another hand:

If the jog does not work, the unit itself could be the cause of this problem.

If the jog works, the problem could be caused by the devices connected to the unit.

-Depending on your computer, especially for a Build-to-Order PC, an amplifier connected to DDJ-SR and the grounding conditions, the touch sensor of the jogs might not work properly as expected.
