Just tried pulling one apart as with previous brands and have given up! undid the 4 screws under the sticky button label on the front and the display panel dropped out of view and now have have a problem. I am going to phone the company tomorrow and ask how they do it.
Because lots of machines have more parts than they need. It was suggested by Japanese motor cycle designers and manufactures that the British motor bike industry failed because they just put too many parts in their products and when copiers start they take apart the item and try to reduce the total number and reduce the costs increasing the profits
