Troubleshooting

When the main printed circuit board (PCB) is replaced on a Spot Vital Signs version 1, the
print function is no longer available. The new function, Pressure Preset, raises or lowers
the blood pressure maximum inflation level for one measurement only. When replacing
the main PCB, replace the switch array as well.
The following table of conditions and error codes provides a quick reference of the
descriptions and probable causes of error codes.
To clear the error code:
Power the Spot Vital Signs off, wait five seconds, and power on. If the error code
reappears then power the Spot Vital Signs off and disconnect the battery for five minutes.
Reconnect the battery and power on. If the error code continues to reappear, call Welch
Allyn for a Service Notification Number (see "Technical assistance" on page 11).
Press the Blood Pressure Start/Stop button to reset flashing patient alarm conditions.
