Such openings include the spacing between the picture tube and the cabinet mask, excessively wide cabinet ventilation slots, and improperly fitted back covers.
If the measured resistance is less than 1.
0 megohm or greater than 5.
2 megohms, an abnormality exists that must be corrected before the unit is returned to the customer.
