How to calibrate the filters?
MW1 users who have a working unit: DON’T DO THE FOLLOWING!! To tune the filters, you have to go into the Service Mode. – Press Mode and switch on the MW. As soon as you can read “Welcome to..” release the Mode button. – Press OK to confirm the warning message. – With the Mode button, step through the pages until you read “Filter Test”. – With OK you can toggle each of the eight filters on and off. – With the alpha dial, you can tune the filters. I think you should try 440 Hz, but if you can’t reach it with one or more filters, try to find a close frequency and tune the other filters to that, too. – When you’re done, switch the MW off and back on. Now the filters are tuned again. Again: all others shouldn’t do that, **only** if they experience *major* tuning problems.
