Approximately once every 5 minutes, the Newton MessagePad saves the time on its clock to a location in memory. When you reset the Newton, its clock is reset to the last saved time. The result is that the clock can lose up to 5 minutes each time you reset your Newton.
Your Newton MessagePad doesn't save the time while it is asleep, so resetting your Newton when it is asleep could result in a greater than 5 minute time loss. We recommend you wake up your Newton before resetting it.
