The bootstrap operations are TBD.</p><p>2. Standby mode is the first mode entered upon power up reset or watchdog resets.</p><p>3. Standby mode is commanded into Manual mode (all subsystems are ON) prior to science (sequence interpreter) operations. This is the “normal” EIS operations route.</p><p>4. Manual to Auto (sequence run) operations can be performed following the selection of a sequence number, i.e.</p><p> i. From Manual mode, select a sequence number. ii. Go to Auto mode iii. This operational procedure is recommended by the J-side (engineering meeting on the 23rd May 2000 at MSSL).</p><p>5. CCD bake-out operations are performed from bake-out mode (minimum power consumption mode). Following bake-out mode invocation (reported in the status packet), the CCD heater power level can be commanded in accordance to the temperature required.</p><p>6. Engineering mode is a special mode. This mode is requested by AJM.</p><p>7. Emergency safe is a mode unconditionally invoked by ground command or autonomously by the on-board health monitor upon detecting voltages, currents or temperatures out of range.</p>
