3.
Observe the monitor front panel. With the monitor off, press the Power
On/Standby button. See Figure 3-1. The monitor must perform the
following sequence.
a.
Within 2 seconds all LEDs are illuminated, then all pixels on the LCD
display are illuminated, after which, the backlight comes on.
b.
The indicators remain lighted.
c.
The LCD display shows the Nellcor Puritan Bennett logo and the
software version of the NPB-195 (Figure 3-2).
d.
A 1-second beep sounds indicating proper operation of the speaker, and
all indicators turn off except the AC Power/Battery Charging
indicators.
e.
The NPB-195 begins normal operation.
Note:
When observing or changing default limits, a 10-second timeout is in
effect. If no action is taken within 10 seconds, the monitor
automatically returns to the monitoring display.
Note:
The descriptions that follow are based on the assumption that Pleth is
the view that has been selected. The steps to changing an alarm limit
are the same if the view being used is Blip.
1.
Ensure that the monitor is on. Press and release the Limits softkey. Verify
that the monitor emits a single beep and the plethysmograph waveform is
replaced with a display of the alarm limits. The high alarm limit for %SpO
will indicate an alarm limit of "100" inside a box (Figure 3-3).

At the end of 10 seconds, with no activity, normal monitoring is resumed.
