3.5.2. WARM UP
The M300E/EM requires about 60 minutes warm-up time before reliable CO measurements can be taken.
During that time, various portions of the instrument’s front panel will behave as shown in Table 3-8. See Figure
3-1 for the layout.

3.5.3. WARNING MESSAGES
Because internal temperatures and other conditions may be outside the specified limits during the analyzer’s
warm-up period, the software will suppress most warning conditions for 30 minutes after power up. If warning
messages persist after the 60 minutes warm-up period is over, investigate their cause using the troubleshooting
guidelines in Section Error! Reference source not found..
