User interface problems:
Symptom
Battery is critically low. Shutting
down...
ECG front-end microprocessor
board error. Contact Technical
Support.
Export/Import unsuccessful
Internal printer error. Contact
Technical Support.
Internal printer is overheated. Try
to print again after 10 minutes to
let the printer cool down.
Possible cause
Device automatically shuts down when it reaches
the shutdown capacity. This prevents file system
corruption. (May lose the last unsaved test.)
ECG Front End detects CPLD Voltage error which
indicates that any ECG data received from it is
invalid. The Front End will notify the
microcompute engine and will display this error.
When the error is acknowledged, the device will
shutdown.
Faulty communication module
Loose or faulty I/O harness
USB flash drive is at wrong port
Faulty Small microcompute engine
The printer error includes the following:
RAM error.
1.
Print head temperature above 70°C (replace
2.
printer FSS).
Flash memory error.
3.
Extended printing has caused the print head to
overheat.
Troubleshooting 33
Suggested action
If you are unable to charge the
battery, replace the battery.
Check connection to the ECG
board. If connection is okay,
replace ECG board. If the ECG
front end error is still received,
replace the small microcompute
engine board.
Replace I/O board.
Reseat or replace I/O harness.
Insert flash drive at correct port
and try again.
Replace small microcompute
engine.
Check communication between
the printer board and
communication board.
If the board tries to communicate
with the printer and the printer
responds with an error message,
then complete a printer
functional test to ensure printer
is operating properly.
Check harnesses on printer to
see if they are loose.
If problem persists, replace the
print head assembly and printer
board.
If printing at a high speed for an
extended period of time, the
printer will overheat and will
notify the small microcompute
engine board that it is
overheating and needs to stop
and cool down.
Contact Technical Support if
printer displays this message
when high-speed printing has not
taken place.
