Online alarm clock for 1:05 am
Before handing the generator check to the next person at the DOC hut, set the alarm for 1:05 am and leave a clear note about what still needs attention. That gives the incoming shift a definite cue rather than a vague request to look sometime during the night. If another reading is due at 2:00 am, record that separately so the two checks are not confused.
During a generator handover, an alarm can appear correctly set while its sound is being routed to headphones left in a pocket or beside a bunk. Check the displayed output and play a brief test sound at a considerate volume before relying on it. Keep the browser running and the computer awake: if either stops, the generator check may pass without an alarm sounding. A separate phone alarm is sensible when missing the check would leave the next person uncertain.
Whoever takes over at 1:05 am may step from a warm hut into a surprisingly cold New Zealand night, while an indoor heat pump or air conditioner masks the change. Put a jacket and torch near the logbook before settling down, and avoid directing conditioned air at the sleeping area if it makes the room uncomfortable. A small adjustment now can make the later 2:00 am reading easier to handle quietly.
