* Risk of explosion: Internal batteries may only be replac
ed by the manufacturer or authorized service provider.
** Risk of explosion: Be careful with the device’s operating temperature. Extremely high or low temperatures can cause ruptures
and
leaks in backup batt
eries and cause damage.
*** Backup batteries will be charged only while the device is operating in the temperature range from 0 to 45 °C.
