Troubleshooting
If the Recording Won’t Start
If you press and the recording doesn’t start, investigate the following
possibilities:
• Is the cardiograph turned on?
The screen should be on.
• Is the Power Indicator on?
If the cardiograph is plugged into AC power via the AC/DC Adapter and the
Power Indicator is not on, check the outlet.
• Is the battery adequately charged?
The symbol should not be displayed on the screen.
• 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 off with the key. (If the cardiograph cannot be
turned off, follow Appendix A to remove the battery, wait for about 20 seconds,
and then install the battery. Connect the cardiograph to AC.)
2. Wait 20 seconds or more and then switch the cardiograph back to On.
3. Press . If the cardiograph turns itself off, the battery is not operating prop-
erly.
If the cardiograph still won’t operate, call your local Agilent service representative.
