The notice described the problem and stated that A Leica Microsystems representative will be contacting the consignee's to arrange this no-cost field update of the instrument. The field update will be scheduled to occur at your convenience within the next 6 months.\n\nThe notice provided the following workaround:  \n\"Advice on action to be taken by the user:\n\" You can continue to use the system pending this field update. Based on our analysis the probability is very remote that an unacceptable patient risk will occur due to the incorrect  BrightCare Plus  functionality caused by the non-conforming photodiode.\n\" However, please ensure that all users of the affected microscope are aware of the  Dangers of Use  as described in section 3.4 and will follow the directions in section 5.3 ( Illumination ) and section 8 ( Operation ) of the user manual when handling a surgical operating microscope   see excerpts below:\n   o 3.4  Dangers of Use :  &do not set the light intensity too high. &  because if  &light intensity is too high, uncontrolled tissue heating may occur. \n   o 5.3  Illumination :  &begin with a low light intensity and increase it until an optimum level of illumination is achieved. \n   o 8  Operation :  &use the lowest comfortable light intensity. \n\nThe notice also requested acknowledgement of receipt of the Field Safety Notice as follows:\n   \"Please acknowledge receipt of this Field Safety Notice with the digital acknowledgment form by either scanning the QR code in your mobile phone or with the following link: https://forms.office.com/r/1WPXW93ugL.\"",
