The manufacturer advises users to take adequate precautions and exercise due care in aspects of position readout accuracy with C-Series Clinac accelerators equipped with the affected software versions. This does not affect the multileaf collimator (MLC).

According to the local supplier, the affected products were distributed in Hong Kong.

If you are in possession of the affected product, please contact your supplier for necessary actions.
