TECHNICAL INFORMATION
LCD Error messages
The ZLM4 has the ability to display error messages. At start up if any of the Power On Self Tests (POST) fail an
error message will be displayed after the version number. If these are “non-fatal” the ZLM4 will continue through
start-up and be ready to run.
After any “fatal” error the LCD will now show a number which will aid in fault finding.
