14.5 Removing the Battery
NOTE
• When the TM80 is not powered off, if you remove batteries, patient data
measured within one minute before the battery removal will be lost.
NOTE
• If the “Low Battery” or “Critically Low Battery” alarm occurs, the TM80
turns off the audio, the screen display the “Local Audio Off” message,
and the screen brightness turns dimmer.
CAUTION
• Some failure conditions, such as short circuits, can cause a battery to
overheat during using. High temperature can cause burns to the patient
or user. If the device becomes too hot to the touch, remove it from the
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.
• Remove the battery before transporting the device or if the device is not
in use or is being stored.
