16. Touch screen calibration
Liftwatch Rail features a touch screen display and will have been delivered in a pre-calibrated state. Should the touch screen
calibration be corrupted or the physical properties of the actual touch screen change, then re-calibration will be necessary. If a
corrupted calibration is detected the system will automatically launch the re-calibration function on start up. The re-calibration
option can be manually accessed either via the system set-up, or by pressing the recalibration button three times in succession
during normal operating mode.
