Ch 1 - Ch 4 -> Auto Lock menu item

In the Auto Lock menu item, you can activate or deactivate the lock-off for the received transmitter.

The lock-off prevents the transmitter from being unintentionally switched off and also prevents any changes to the transmitter’s menu.

If you want to change settings in the transmitter’s menu while the lock-off is active, you have to temporarily disable the lock-off:

Press the jog dial to open the menu.
The following view is displayed:
Turn the jog dial to set the desired value.
Press the jog dial to save your setting.
Or
Press the ESC button to cancel the entry without saving the settings.

For the set value to be applied to the received transmitter, you must synchronize the channel (Connecting to the EW-DX EM receivers / synchronizing the EW-DX EM).
