5.6.5 Operational Performance
Table 5-7 lists symptoms of problems relating to operational performance (no
error codes displayed) and recommended actions. If the action requires
replacement of a PCB or module, refer to Section 6, Disassembly Guide.
Table 5-7: Operational Performance Problems
Condition
Recommended Action
1. The display appears to
be operational but the
readings are suspect or
nonexistent.
1. Check the hose and cuff for leaks and that a
good connection is made. Replace cuff or
hose if necessary.
2. Perform verification of pneumatic system
as described in Section 3, Performance
Verification (Paragraph 3.3.2).
3. If the condition still persists, replace the
UIF PCB.
4. If the condition still persists, replace the
pump assembly.
5.6.6 Stacked Configuration
Table 5-8 lists symptoms and recommended actions for problems encountered
while in the stacked configuration. Refer to the N-3000 or the N-3200 service
manual for more troubleshooting information.
Table 5-8: Stack Problems
Condition
Recommended Action
1. While stacked with
N-3000 only, BATTERY
IN USE/BATTERY LOW
indicators on the N -3000
and N-3100 light steadily
while they are connected
to AC. Both units are
operational.
1. If stacked with N -3000 only, ensure that
the SPS power supply is plugged into an
operational AC outlet. If it is, and the green
indicator light is not lit, replace the power
supply.
2. If the green SPS indicator is lit, ensure that
the power supply is properly plugged into
the N -3100.
2. While stacked with
N-3200, BATTERY IN
USE/BATTERY LOW
indicators on the N -3200
and N-3100 light steadily
while they are connected
to AC. Both units are
operational.
1. Ensure that the power cord is properly
connected to the N-3200 rear panel and an
AC power outlet.
2. Ensure that the N-3200 main power switch
is turned on.
