2. To display limits without setting new limits if audio is enabled, press and release the
alarm key twice. The first press turns off the alarms and the second turns them
back on and causes the high and low limits to be displayed for three seconds. The
monitor will then return to normal operation.
3. To display limits without setting new limits if the audio is disabled (audible alert icon
visible), press and release the alarm key. The high and low limits will be displayed
for three seconds before the monitor returns to normal operation. Press and
release the alarm key to disable the audible alarms.

Battery Life

The Model 511 displays a battery icon to indicate:
• fully charged batteries, over 4 hours of battery life
• less than 4 hours of battery life
• indicates less than 2 hours of battery life
• (flashing) less than 15 minutes of battery life
When the battery voltage reaches the 2 hour level
reaches near depletion, the battery icon will flash at a rate of once per second, and the alert
audio will sound, this alert tone cannot be muted (even if alerts are disabled). Continued
use of the monitor at this point will result in the monitor shutting itself off.
NOTE: The above information is based upon normal monitoring conditions (e.g. sensor
on patient, new alkaline batteries). Use of non-alkaline, previously used alkaline, or
rechargeable alkaline batteries will affect the battery life times. Prolonged use of the
backlight can significantly reduce overall battery life.
The battery icon may appear fully charged for the first minute after power up, after which
it will reflect the true battery charge.
NOTE: When operating from the external power supply the battery icon does not reflect the
condition of the batteries. See "External DC Supply".

Monitoring Saturation and Pulse Rate

Once the Model 511 is powered on and a sensor is connected to the monitor and properly
applied to the patient, numerical SpO
display. A "pulse activity bar", derived from the pulsatile signal, is also displayed. The
monitor automatically adjusts the activity bar's length to produce an easily visible display.
Verify the pulse activity bar reflects the patient's pulse. The bar should show regular
rhythmic movement. Erratic or non-rhythmic pulse bar activity may indicate a poorly
positioned or applied sensor, or may be indicative of excess patient movement at the sensor
site. Check the sensor site and if necessary, attempt to reduce patient movement.
Violation of the upper or lower saturation auto alert limits shall immediately cause a "H"
or "L" to flash within the borders of the display alarm icon, even if the icon itself is
disabled.
