5. Using the standby switch turn o the unit, then turn it back on. Verify the following:
• All the displays and indicators light
• The software revision appears
• The prompt tone begins
NOTE: If the unit has been used in the last 2 hours, the patient history query appears.
6. Adjust the set temperature to silence the prompt tone.
7. Check the patient probe. If the probe is below 30 C, the display will show -L-. Warm it by placing it between
your ngers, and verify that the baby temperature reading increases.
8. Unplug the patient probe and check that both visual and audio alarms trigger in the Baby control mode.
9. Check the canopy lift mechanism. Push the lift pedal and verify the canopy raises smoothly in one
continuous movement to its upper limit, the heater doors open, and the unit shifts into warmer operation.
Check that the pedals on both sides of the unit raise the canopy.
10. With the canopy raised, check the operation of the panel at the foot of the bed. Check that after you lift
up on the panel, it swings down and hangs perpendicular to the bed. Check that the panel is securely
attached. Check that it swings back up and seats in the closed position.
11. Lower the canopy and verify that it stops when you remove your nger from the hand switch. Check that it
stops automatically at its lower limit, and that the canopy seal makes contact with all four bed sides, and
that the unit shifts into the incubator operating mode. Check that the raise and lower buttons at the head
of the bed on both sides of the unit raise and lower the canopy.
12. If so equipped, check the operation of the bed elevating system. Raise and lower the bed along its entire
travel range, checking that the mechanism operates smoothly. Check that the pedals on both sides of the
unit raise and lower the bed.
13. Check the power failure alarm and the battery backed up memory. Make note of the current control mode
and temperature settings and wait one minute, then unplug the OmniBed from the wall outlet. An alarm
should sound and the power failure indicator should light. Wait one to two minutes and plug the OmniBed
back in. Verify that the alarm cancels and that the OmniBed returns to the same control mode and
temperature settings it displayed before the power interruption.
NOTE: A fully charged battery should supply the power failure alarm for 10 minutes minimum (IEC 60601-
2-19 clause 101.3). If the alarm is tested for the full 10 minutes, the OmniBed must be run at least two
hours to recharge the battery before it is used with a patient. Total recharge time is 10 hours. The battery
charges only when the unit is powered on.
14. Perform the Leakage Current and Ground Resistance checks in Chapter 3 of this manual.
