Troubleshooting
Chapter 10 - Training Program 129
Whenever the monitor has been opened, there are specific steps regarding
reassembly, described in the disassembly instructions in Chapter 6, that must
be followed. If these instructions are not followed, various errors may result.
See Chapter 6 for a review of the disassembly and reassembly procedures.
For monitors that are defective on arrival, first go through points 1 to 4 in the
troubleshooting table above. If these are not successful, and a replacement
monitor is necessary, please contact an Philips sales representative to arrange
a replacement.
4 The fuse of the external
power supply on the A1 can
be blown if there is a defect
on the main PCB. In this
state the monitor will no
longer boot. Therefore if the
AC indicator on the A1 does
not light...
Step 1: Try to boot up the A1.
Note: Do not plug in an operational external
power supply to an A1 that will not boot up.
Step 2: If the monitor fails to boot, use a
different A1 to test the external power
supply for operation, if possible.
If the fuse is blown, the Battery Charge,
green LED, indicator will not come on
and the DC power indicator in the
display screen will stay on.
Note: The fuse in the external power supply
is not replaceable.
5 The A1 and A3 NIBP valves
can stick if they are inactive
for several months in
extreme environments.
Exercise the valves by using the NiBP test or
just through normal use. They will free
themselves up.
6 In the A3 with an optional
integral recorder, there is a
recorder error message.
Press the
SNAPSHOT button on the recorder.
• If the paper advances, the problem lies in
the monitor, not the recorder.
• If the paper does not respond, then the
problem lies in the recorder. Replace the
recorder.
