Description

For firmware 4031.071 the firmware version can be ascertained by holding the inc & dec buttons pressed while powering the unit on. The display will show four sets of 2 digits continuously while the buttons are pressed e.g. 40-31-00-71 for the 4031.071 version.

For earlier versions the cover must be removed and the label on the eprom looked at to ascertain the firmware version. Ensure that the unit is unplugged from the mains supply before removing cover, and that the cover and screws are replaced before reconnecting.
