Hi,
1, switch off set with mains switch.
2,Press volume down and channel up buttons on the front of the reciever at the same time.
3,Keeping these buttons pressed in -switch on with the mains switch
4,When the set starts up it will be in service mode.
5,Release the two buttons.
Use the channel up and down buttons to move between options
Use the volume control buttons to change the data
To store the data use the standby button
To exit the service mode turn off the reciever with the mains switch
Hope this helps
