Trim I Diagnostic and Performance Verification Tests 
Diagnostic tests are included in the Biomed Service Program and are used to identify and to 
troubleshoot a technical problem with the PageWriter Trim I cardiograph. 
CAUTIONEnsure that the AC power cord is plugged into the rear of the cardiograph and into a grounded 
electrical outlet before using the Biomed Service Program. If the cardiograph is powered by battery 
power only while using the Biomed Service Program, the battery will fail and will not recover.
