What to do if Philips M1013A IntelliVue G1 Measuring Instruments show -?-, INOP tone, and blinking Setup LED?

If your Philips Gas Analyzer displays '-?-' instead of numerics, emits an INOP tone, and the Setup LED is blinking, this indicates a hardware problem. Check the connection to the monitor. Try switching the Gas Analyzer off and then on again to resolve the issue.
