IMPORTANT BATTERY CARE INFORMATION!

The Actiheart device contains a miniature rechargeable battery which must be cared for correctly to
maximise service life. Following any long recording, always ensure the battery is at least partly re-charged -
do not leave it completely flat before storage. However, it need not be completely recharged. If the device is
to be stored for an extended period then it should ideally be part-charged rather than left either completely
full or empty.
