To do a complete re-set:
Unplug or switch off at the mains socket.
Wait at least 5 seconds.
Restore the power and wait until the message 'PLS WAIT' disappears from the display then press the front panel on/off button, keep it pressed until 'FORMAT' message is displayed and then release the button.
Wait 45 seconds for the DTR to complete the reset procedure.
The unit will be reset to the factory default but will delete all saved programmes.
