Service manual

DINAMAPTM Portable Monitor Model 8100 has been designed to provide
safe and reliable operation in medical environments. As with all medical
devices, if the accuracy of any determination value is questionable,
first check the patient’s vital signs by alternate means and then check
the monitor.
Determination Unsuccessful Alarm (899)
This alarm is indicated by an alarm tone and a flashing 899 in the PULSE
display. The alarm condition indicates that the monitor is unable to make a
determination. Possible causes include: sudden changes in blood pressure;
excessive arrhythmias; cuff too loose; or arterial obstruction. In auto mode,
the monitor initiates two determinations at a higher pump-up pressure
followed by seven determinations at the original pump-up pressure until a
successful determination is made. No more than nine retries will be made if
the 899 alarm condition persists. Move cuff to another location and attempt
another determination.
Power-On Self Check (888)
The power-ON alarm occurs anytime that power is interrupted and then
restored to the monitor, or after three (3) minutes in cal mode. The alarm
lasts for three seconds, during which time the monitor displays all eights
(888s) in the digital displays; toggles all LED indicators on and off and issues
an audio tone.
After the alarm is issued, the monitor enters the manual mode of operation
with adult default alarm limits in effect.
Excess Time at One Pressure Alarm (855)
This alarm is indicated by an alarm tone and a flashing 855 in the PULSE
display. The alarm is generated if the cuff pressure is held at one pressure
level for more than 60 seconds. Check the cuff and hose connections for
kinks or blockages and then initiate another determination.
