In response to future updates to Apple iOS and Google Android operating systems, the UNDOK App may no longer function properly with certain earlier SANGEAN products. This change only affects support for the UNDOK App. Your product itself will continue to operate normally using the buttons on the device or the remote control.
If you currently use the UNDOK App to control your SANGEAN product, please refer to the information below to check whether your product is affected.
How can I confirm whether my product is affected?
Please check whether your product model and the first two characters of the serial number, referred to as the SN Prefix, are included in the affected product lists below.
The SN Prefix can be found on the barcode label located on the bottom or back of the product. Please refer to the photo below.
