6. Switch the power On and verify the following sequence:
a. An alternating two tone audible alarm sounds for approximately five seconds, all
the indicators illuminate and “188.88” appears in the three temperature displays.
b. All indicators are extinguished except for the air control and the enable
indicators. The temperature displays change to show from left to right:
Patient Air Control
Temperature Temperature Temperature
XX.XX (software 60H (AC frequency; 39.0°C (maximum
version, for ex:01.01) 50H for 50 Hz units) air control temperature)
c. An operator prompt tone sounds, and the control temperature display flashes
“33.0°C”. The operator prompt tone will sound every two seconds until a control
temperature is entered by pressing one of the temperature switches (
?
or
M
).
d. If the system failure alarm sounds, note the error code and switch off the
unit. Wait ten seconds and switch the unit back on. If the system failure alarm
recurs, remove the incubator from use. Then, call for service.
7. Adjust the control temperature to silence the prompt tone.
8. Check display illumination and the audible alarm by depressing the Alarm Silence
switch until all the indicator LEDs illuminate and “188.8” appears in the three
temperature displays (approximately five seconds). An audible alarm will sound.
9. Check the Enable switch. Press the Enable switch. The enable indicator should
illuminate and go out after approximately 12 seconds. Verify that pressing the temper-
ature switches (
?
and
M
) has no effect when the enable indicator is extinguished.
10. Check the analog to digital calibration and the line voltage. Depress the Enable
switch until the temperature displays show, from left to right (approximately five
seconds):
Patient Air Control
Temperature Temperature Temperature
25.05°C (±0.2°C) 37.95°C (±0.2°C) From 09.00 to 11.00
(low calibration point) (high calibration point) (Service use only)
Note: An audible alarm will sound to indicate that the actual temperatures are not
displayed.
11. Check the patient probe. Warm the patient probe by placing it between your
fingers. Verify that the displayed patient temperature increases. If you have an
ASTM approved thermometer, accurate to ±0.1°C, place the thermometer and
the patient probe in a glass of warm water. Stir the water and wait several minutes
until the thermometer reading stabilizes. Verify that the patient temperature shown
on the control panel is within 1°C of that shown on the thermometer. Replace the
probe if the difference exceeds 1°C.
12. Check the normal range of air control temperatures. Press the Enable switch to
activate the temperature switches (
?
and
M
). The enable indicator will illuminate.
Press and hold the
?
switch. Verify that the lowest control temperature attainable is
20.0°C. If the enable indicator has gone out, press the Enable switch again. Depress
the
M
switch and verify that the air control temperature cannot be set above 37.0°C.
13. Check the extended range of air control temperatures. With the control
temperature set to 37.0°C, sequentially press the Enable and Override switches.
On controllers with serial numbers beginning with HBJ and HCE, the enable
indicator should illuminate and the override indicator should blink (On all other
controllers both the enable and the override indicators should illuminate and
