Keeping Your Monitor Awake When Taking Breaks During a Long Piece
The Performance Monitors are designed to power down after a couple of minutes of inactivity. To keep your monitor awake when you're taking a break during a long piece, periodically press Display or Change Display, Units or Change Units on the monitor face. This registers as activity for the monitor and will keep the monitor from shutting down.
Don't press Menu or Menu | Back as that will end your workout.
