Hi
Philips MX450 don't boot system.
After pressing the power button, all indicators light up and somewhere in a minute the speaker starts to generate three short and two long signals.
The device can be turned off/on.
Voltage at the control points normally.
On the mainboard is a 1 gig MicroSD memory card.
In the readers card is absolutely not recognized, it’s broken.
For example on the fetal monitor Neoventa Stan S31 on CF memory card is a system boot loader, and patient examination results.
Maybe someone can clarify what is on MicroSD.
At Philips assortment there is only one option: exchange the motherboard for an extra charge smile
