The rover modem should be commanded in the next-day runout sequence to perform a 600 second modem heating at wakeup. If no overnght APXS operations are to be conducted, the wakeup rover modem heating should be extended to 900 seconds. Modem reheating should be triggered by an excessive number of frame retries on the rover-to-lander link, and the reheating should continue for five minutes or until the rover modem reaches +30 C. However, if the LMRE radio is commanded OFF in the lander sequence, then the reheat to get to +30C is not needed. This requires some coordination of timing between the LMRE ON times and the rover transmissions. The sequence planners should consider the uncertainty in event completion times introduced by any required modem reheating cycles.
