ECG Tests
These instructions describe how to test the ECG functions.
Each of the ECG tests assumes the unit and the simulator are still set up as
they were at the end of the previous ECG test.
If all results are as described, the unit passes that portion of the test. Return to
the main Diagnostic Test menu by pressing
If there is any failure, begin troubleshooting and repairing the unit as needed.
See "Troubleshooting" on page 3-1 and Table 3-7 "Operational Problems -
ECG Monitoring (Pads or Leads)" on page 3-19.

Checking settings
In areas with 50 Hz power, the AC Line Filter should be set to 50 Hz. If the set-
ting is incorrect, access the Configuration Mode and correct it. See "Configu-
ration Mode" on page 2-10.
The PCI setting should always be Off (factory set default). If it is On, press the
Volume Up and Down arrow keys simultaneously to turn it Off. (See Figure 2-
1 on page 2-11.) The software feature this setting controls is not used in the
M3500B/M5500B.
