5-7 HOW TO UNDERSTAND MILLI-Q MESSAGES
It is possible for various messages to be displayed on the Milli-Q LCD while you are using the Milli-Q. While a
message is being displayed, either the Yellow Service LED or the Red Alarm LED will be blinking.
The table below provides a summary of these messages, what they mean and what to do when you see them.
You may also refer to Chapter 7 (Troubleshooting) for more information about these messages and
other troubleshooting items.
Please contact Millipore if you desire more information regarding what to do when a message appears on the
Milli-Q.
