3.4.5 WITTY PHOTOCELL FIRMWARE UPDATE
Similarly to the timer, it is also possible to update the photocell firmware. Connect the photocell WHILE OFF
to the PC using the USB cable. After the operating system has recognized the driver, the LED blinks with a
red-green light. Press <Photocell Firmware Update>. After a few moments necessary for the download, the
firmware is applied and a dialog window informs that the update has been completed.
Disconnect the USB cable from the photocell and switch it on to check that it is working correctly.
CAUTION: Do not update the timer and photocell firmware if the battery charge is
lower than 25% (charge the battery for a few hours first, making sure that the
charge level is sufficient).
