# 4 📐 Calibration

The pre-assembled Bittle X should have been calibrated. You may proceed to [**Play with Bittle X**](/5-play-with-bittle-x.md). 

However, if you want to adjust the calibration by yourself, please refer to the [Joint Calibration](https://docs.petoi.com/joint-calibration) in the Doc Center for more details.

{% hint style="info" %}
For pre-assembled Bittle X, there is **No** need to disassemble the head and leg parts from the body for joint calibration.
