6.3 Transmission errors
To avoid errors in data transfer, the monitor checks the data transmitted. If an error has occurred, E004 appears
on the display.
6.4 Check list
Please run through the following check list if errors occur when using the Mobil-O-Graph
®
. Many faults are eas-
ily remedied.
■
Check whether all cables are securely connected, and the infrared interface is correctly pointed towards
the monitor.
■
Check whether the monitor, computer and printer are switched on (depending on version obtained).
■
Check whether the connector cable is fitted to the correct serial interface (COM1 to COM4).
■
Check whether the batteries are adequately charged.
Note:
Some errors are associated with a continuous alarm for safety reasons. The continuous alarm can be
stopped by pressing any key. If there is pressure remaining in the cuff, open the cuff immediately.
