If the system requires a cooling off period after exceeding maximum heat units, what must be done before resuming exposures?

Explanation:
The X-ray tube can only hold a certain amount of heat at a time, measured as heat units. When you exceed that limit, the system requires a cooling-off period so the anode and housing can dissipate heat safely before you resume exposures. During this pause you follow the cooling time specified by the equipment or cooling chart. Increasing exposure time, raising kVp, or speeding up the generator would add more heat rather than reduce it, so they aren’t appropriate ways to continue after hitting the limit.
