Errors

Green LED OFF

The Green LED indicates that power is present on the HMIA circuit board.
If the Green LED is not on then the LED has either burned out or the internal
power connector is dislodged. Return the HMIA to ZOLL for service.

Flashing Red LED

The Red LED flashes only when there is a problem with the CPU or the internal
self-calibration fails. Using a small solid wire (paperclip), press the reset button
RST
( ). If the Red LED continues to flash return the HMIA to ZOLL for service.

No Temperature Reported On Hospital Monitor

1. Observe Red LED.
2. If it is flashing then follow instructions for
3. If the Red LED is not flashing then disconnect the hospital monitor from
4. Using a DMM measure the resistance between the two pins.
5. Using the chart
6. If the resistance value is correct then the HMIA is functioning to
7. If the resistance value is wrong, then test Alsius interface cable for shorts
8. If it passes the test, then press the reset button (
9. Repeat step 5 above.
10. If the resistance value is still wrong, then disconnect the RS232 cable
11. Wait for an additional 20 seconds for the HMIA to re-establish
12. If the resistance value is wrong then return the HMIA to ZOLL for service.
Incorrect Temperature Reported On Hospital Monitor
1. Disconnect the hospital monitor from the HMIA interface cable.
2. Using a DMM measure the resistance between the two pins.
3. Using the chart
