Is the cardiograph turned on? The LCD screen should be on. Use the shift and
up/down key to increase/decrease intensity.
Is the AC power light on? If the cardiograph is plugged in and the AC light is
not on, check fuses.
Is the battery adequately charged? The low battery message (in the upper-left corner of
the screen) will appear if the battery is not charged.
Is the cardiograph out of paper or is paper
jammed?
The cardiograph will not record an ECG unless
paper is loaded and no jam exists.
Is the paper sensor lens dirty or obstructed? Clean sensor lens.
Is the paper door completely closed? Open paper door slightly and close it. Listen for the
door safety latch to lock.
Is there an error message? The error messages that display on the screen will
instruct you as to what action to take. If it is some-
thing that you can correct, the message will instruct
you as to what to do. If an error number displays,
perform the following steps:
1. Turn the cardiograph to STANDBY from the
front panel.
2. Wait 20 seconds or more and turn the unit on
again.
3. Press AUTO or MANUAL. If the cardiograph
turns itself to STANDBY, the battery is not
operating properly.
4. If error persists, call HP Medical Call Center
