Is HOLD switch set to ON?
Leaving the power switch set at HOLD activates the HOLD function in which all button operations are disabled.
*Even if HOLD is on, you can still operate the R-07 from a mobile device.
If the buttons are unresponsive or require multiple presses, even when HOLD is turned off, there may be a possibility of a malfunction. For detailed information about repairs, please consult an authorized retailer near you or contact our customer support.
