17.3 External Battery
You can connect an external battery to pin 3 (BATT) of the power connector instead of pin 9 of the key-
board connector. For more information refer to the keyboard chapter of this manual.
Attention: Pin 3 (power connector) and pin 9 (keyboard connector) are connected to the same signal. The pins are not decoupled,
therefore do not connect two batteries.
