patient and place aside until it cools. Then remove the battery from the
device, and contact your service personnel to identify the cause of over-
heating.
• Avoid scraping the metal contactor in the battery compartment while
removing the lithium-ion battery pack or AA battery frame. Otherwise,
the broken contact will affect the power supply performance.
