number display
Summary of status messages
and numbers.
Model 511 User's Manual
If the Model 511 cannot detect "valid" saturation data with which to update the display, the
previous contents of the display shall be "held". Should the display be held for more than
ten seconds, a "-" character will start to flash within the borders of the display alarm icon,
even if the alarm icon itself is disabled. If the Model 511 cannot detect valid pulsatile data
from the sensor within sixty seconds, the saturation and pulse rate displays will blank out
(display "--" and "---" respectively). If the display is held longer than ninety seconds the
Model 511 will emit an audible unlatched alarm (if enabled) and REPOSITION SENSOR
along with the number 9 will appear in the display. If at any time the monitor processes
valid data with which to update the display, the "-" will stop flashing, the display will be
updated, the timer reset to zero (seconds), and the audible alarm, if active, will be reset.

1 Sensor not connected to monitor.

3 Low signal strength. Pulse strength as detected by the
sensor is too small for proper monitor operation.
4 Insufficient light. Sensor placed on a site too thick (or
opaque) for adequate light transmission.
5 Pulse out of range. Pulse must be 30-250 bpm inclusive.
6 Light Interference. Ambient light sources (sunlight,
warming lights, etc.) are interfering with sensor
operation. Shield sensor from these light sources.
7 Sensor fault. Remove sensor from use and contact
qualified service personnel.
8 Monitor fault. Record the error number that appears in
the pulse rate display. Remove the monitor from use and
contact qualified service personnel.
9 Bad signal, monitor not receiving valid signals from
sensor. May be caused by excessive motion, cardiac
arrhythmia or other situations leading to poor signal.
Check patient status, reposition sensor.
