92th day of attachment

My colleagues and i had to stay in bme department until 3 pm as there is a sparrowhawk exercise for today and tomorrow. We are advised not to go to the wards during the exercise unless the calls that we received are urgent. Before the exercise is carried out, jupiter masks from some departments are not working due to incorrect calibration done before in use. While the exercise carried out, i did most of in-house repair until 3 pm as we received a call from from Clinic C about their indirect opthalmoscopes not working as the batteries are faulty. After testing, the batteries and opthalmoscopes seems to be working. I believe that the batteries were not fully-charged before using the opthalmoscope.
