Just Row workouts longer than one minute or longer than 100 meters and preset workouts are saved to the PM automatically. After your last stroke of a Just Row workout, press Menu or Menu | Back twice and the meters rowed will be saved to memory. This can also be achieved by waiting 6 seconds after your last stroke and pressing Menu or Menu | Back once.
The PM5 stores over 1000 workouts in memory. PM3s and PM4s store your 10 most recent workouts in memory. If you are using a USB flash drive or a LogCard with your PM, your workouts will be saved to those devices instead.
