      Without proper knowledge in electronics, and work experience, never attempt to change any data value stated above.  When adjusting these data values, one must be aware of what will happen when each item data value is changed.  It is best to write down the present data value at the set, before changing any data value; so that, you can revert back to the same data value as before, if the set is found abnormal after your adjustments.
