WARNING: Use the servo mode unless the manual mode is specifi-
cally prescribed. While both modes require patient monitoring, the
manual mode requires constant attention. In the manual mode, you
must take the responsibility for detecting changes in the environ-
ment (drafts, direct sunlight, phototherapy lamp usage, etc.) or the
patient condition requiring heater adjustments in response to these

1. Connect the power cord to a properly grounded AC power source.
2. Place the power switch in the On position. During the first seconds of
operation, the warmer performs a self check of the control system. The
software is verified, calibration is checked and operation of the solid
state relay controlling the heater is verified. All displays and indicators
are lit and the audible alarm is sounded. If the self check detects a
failure, the alarm stays on and service is required.
Note: The Warmer begins operation in the Manual Mode, described in
Step 3. To operate the warmer in the Servo Mode, refer to the Servo
