Error M010 on the Philips BV300 at startup with X-ray available is very often the battery on the COMBO board, so you’re thinking in the right direction.
That battery maintains system configuration and calibration data.
Yes, you can change it, but you must be careful:
- If you change the battery with power OFF, you can lose configuration/cal data.
- The usual trick is to replace the battery while the system is powered ON so memory stays alive.
- It’s typically a coin cell on the COMBO board.
If the battery is dead too long already, you may need to reload system configuration/calibration after replacement.
