SERVICE CAL Mode
The SERVICE CAL key is a hidden key about one inch to the right of the ZERO key. Touching the hidden
SERVICE CAL key five (5) times in a row will display the SERVICE CAL MODE menu. While in service
calibration mode, the patient is not being monitored, and the diagnostic (calibration) data values are displayed
and trended.

While in the SERVICE CAL MODE menu, the menu prompt line will display a warning indicating that the
patient is not being monitored, because:
• The monitor has switched to display the diagnostic (calibration) data values.
• The patient has been disconnected from the 91518 in order to supply calibration gases.
• The breath detection is disabled, and the displayed values are not based upon breath detection.
However, the waveform will continue to be displayed as an aid for determining steady gas flow, and the alarms
are NOT disabled.
The SERVICE CAL MODE menu is designed for use by qualified personnel, and may contain information
useful to a biomedical engineer, a field service engineer, or Spacelabs Healthcare product support. The
following information displays while in SERVICE CAL MODE:
CO2= xx mmHg — Instantaneous carbon dioxide data in mmHg
O2= xx % — Instantaneous O
