Identifying ECG Problems
6-4 Troubleshooting
If the Recording Won’t Start
If you press or and the recording doesn’t start, investigate the
following possibilities:
l Is the cardiograph turned on?
The screen should be on.
l Is the AC power light on?
If the cardiograph is plugged into AC power and the AC light is not
on, check the two line fuses. See “Replacing the Fuses” in “Main-
taining the Cardiograph” , for fuse information.
l Is the battery adequately charged?
The Low Battery message (in the upper-left corner of the screen)
should not be displayed.
l Is the cardiograph out of paper? Is the paper jammed in the cardio-
graph?
The cardiograph will not record an ECG unless you have loaded
paper or cleared the paper jam. See “Maintaining the Cardiograph”
for details on loading the paper. Reloading the paper will clear a paper
jam.
l Is the paper sensor lens dirty or obstructed?
Clean the paper sensor lens. See “Maintaining the Cardiograph” , for
more information.
l Is the paper door completely closed?
Open the paper door slightly and close it tightly. Listen for the door
safety latch to lock.
l Is there an error message?
See “Error Messages” later in this chapter for more information.
If the cardiograph still won’t operate, perform the following steps:
1. Switch the cardiograph to Standby (off) with the switch.
2. Wait 20 seconds or more and then switch the cardiograph back to On.
