Page C-12 Infinity Gamma Series VF4
Biomedical Support
This section of the appendix is designed for the Biomedical per-
sonnel of your hospital. It includes an overview of the Biomed
menu, basic setup, saving setups, diagnostic functions, and cali-
bration check procedures for NBP. This appendix is not a substi-
tute for the Infinity Gamma Series Service Manual that is
available from Dräger.
CAUTION: Verify that the monitor’s line frequency under the
“Service” menu is set to match the 50 or 60 Hz mains power line
frequency of your hospital. The line frequency determines the cen-
ter frequency of the ECG notch filter. The filter greatly reduces line
frequency noise on the ECG waveform. Refer to the Service manual
for details how to change frequency.
