Delete linking data in BT SLIM
Follow these steps to erase data from a BT SLIM device. Hold
the button on the device for 14 seconds. (The green LED will
flash after seven seconds. It is important to continue holding
the button until both LEDs start to flash).
This process will erase all connection data with all smartphones
that may have been linked, as well as all copies of original remote
controls. Mobile handsets will therefore need to be linked again
to re-establish an automatic connection.
