External battery assembling:
If customer wants to connect an external battery (check for the appropriate connector in the chapter
DESCRIPTION OF THE CONNECTORS), then some precautions have to be made:
-
The battery is protected from charging. Do not use a charchable battery
The RTC device defines a voltage level of 2.0V...3.6V, so do use an external battery, which will be in this
range (inclusive the diode which is already assembled onboard)
