What is the correct way to connect a battery pack, and what precautions should I take?

When connecting a battery pack to your main unit, please make sure both the main unit and the battery pack are turned off.

Here’s the easiest way to connect them safely:

1. Turn off both the main unit and the battery pack.
2. Connect them using the expansion cable.
3. Turn on the main unit – the battery pack will turn on automatically.
4. Once the battery pack icon shows up on the main unit’s display, the connection is successful.

⚠️ Important: Do not connect while the main unit is powered on. This can cause an “FC” error. If that happens, simply disconnect the cable, turn off both units, and reconnect following the steps above.
