Generally speaking OTTO is engaged from anywhere on the climb (not less than 200ft)' until under 2000ft or so on final approach. There is a lot of variables and but those figures would cover 90% of flights.
During a rest changeover the crew member that is Pilot Flying (PF) will give a handover briefing to the incoming crew. The PF will put on the full harness and the Pilot Monitoring (PM) will formally handover communications to the PF before getting out of the seat. The first of the refreshed crew will then get in and put on the full harness. When ready they will state: "I have control; My radios". The former PF will then swap out with the second refreshed crew member. When that member is seated they will state either "I have control" or "My radios" depending how they want to allocate the duties between themselves. This crew change procedure ensures that there is no doubt as to who is flying the aircraft and who is monitoring it. There are other seating requirements that are dependent upon rank. A Captain may occupy either seat as PM but only the left seat if PF (Unless a standards pilot with a current RH seat qualification), A FO may occupy either seat as a PM but only the RH seat if PF. A SO can occupy either seat as PM or PF (They can only be in a "window"seat above 20,000ft).
During the time that only 1 pilot is seat at the controls the full harness must be worn.....in case of sudden turbulence or Autopilot failure.
