3.5.1 Isolating the Problem, System Level
1. Determine if the problem is in the main NIBP unit or in one of the add-on accessories.
2. If the problem is in the accessory, check the recorder unit for correct paper, correct
installation, and paper jams.
3. If the problem is in the main NIBP and/or SpO
2
section, rule out these simple
problems first:
If AC power is available, then the green LED adjacent to the front panel
ON/STANDBY keys should be illuminated. If not, connect the power cord to a live
power outlet. If the green LED fails to illuminate, there is a probable power supply
malfunction.
Check the battery operation LED. Steady ON indicates battery operation. A flashing
LED indicates a near depleted battery. If the green LED is NOT illuminated, then the
battery or power supply/charger may be suspect.
Confirm correct operating parameters selection (i.e., correct patient size selection,
(Adult, Neonate, Ped.) and NIBP cuffs to match. In units with SpO
2
, verify that a
sensor is connected to the unit and it is of the proper type/size.
