Important Warning: The touch firmware for 4243L monitors with IntelliTouch technology is not field upgradeable. Performing this update requires a proprietary hardware programming jig alongside specialized, proprietary software.

Note: Updating touch firmware on IntelliTouch units is extremely rare and is highly unlikely to resolve touch performance or calibration issues. If firmware diagnostic testing is deemed absolutely necessary by technical support, you must create an RMA and send the monitor directly to an authorized Elo service depot.
