3. At a CIC Pro center, verify that the Event Marker message is displayed.
Pause alarm
This test verifies that the transmitter enters into the PAUSE ALARMS condition for
approximately 5 minutes.
1. With the transmitter operating, press the Graph and Verify Leads buttons
simultaneously. The Lead Status and Change Battery LEDs flash twice to
acknowledge the switch was pressed.
2. Once the transmitter enters the PAUSE ALARMS condition the Pause Alarm
LED begins flashing, and flashes for the programmed period. (Typically 5
minutes but this value can be changed by reprogramming the transmitter.)
3. At the end of the period the Pause Alarm LED stops flashing.
4. Terminate the PAUSE ALARMS condition by pressing the Verify Leads and
Graph buttons simultaneously. The Pause Alarm LED stops flashing.
Pacemaker transmission
This test verifies detection of a pace pulse and transmission to the CIC Pro center
display.
1. Connect an ECG simulator to the transmitter.
2. With the transmitter operating and ECG waveforms from the transmitter
displaying on the CIC Pro center, trigger a pace pulse at the ECG simulator.
3. Verify a pace mark on the CIC Pro center. (Ensure that the PACE function is
enabled on the CIC Pro center.)
ECG waveform transmission
This test measures the gain through the transmitter/receiver system.
1. Connect the ECG simulator to the transmitter.
2. Verify that ECG signals from the transmitter display at the CIC Pro center.
3. Verify the ECG gain at the CIC Pro center is set to 1x magnification.
4. Press the Graph button on the transmitter to trigger a graph run.
5. Measure the graph output. Signal level should be 1 cm (2 large boxes on graph
strip) for a 1 mV input.
Completion
If the transmitter fails any of the above tests, return it to the factory for service.
