Is there a time limit to when the monitor can be set-up? Can it be set-up before the visit?

It can be set-up prior to the visit e.g. batteries inserted, time settings checked, any previous recordings deleted. However, the recording should only be started when the subject is in front of you and ready to have the monitor attached. Once the recording has been started, state “This is Subject#, date, start time and visit number.” and attach the monitor to the subject.
