the problem persists contact Welch Allyn Customer Care.
E4.3 à
Device EEPROM save failure. Verify that
the batteries are fresh. If the problem
persists contact Welch Allyn Customer Care.
E4.4 à
Device EEPROM starting handshake failure.
Verify that the batteries are fresh.
If the problem persists contact Welch Allyn Customer Care.
E4.5 à
Device EEPROM response failure. Verify
that the batteries are fresh. If the
problem persists contact Welch Allyn Customer Care.
E4.6 à
Transmit failure to the Device EEPROM.
Verify that the batteries are fresh.
If the problem persists contact Welch Allyn Customer Care.
E4.7 à
Can’t initialize the device EEPROM. If
the problem persists contact Welch Allyn Customer Care.
E4.8 à
Device was not calibrated Replace the device with a calibrated device.
E5.0 à
Heater is not working properly. Try
another cycle. If the problem persists contact Welch Allyn Customer Care.
E5.2 à
Heater fail-safe failure. Contact Welch Allyn Customer Care.
23 à
Host Interface Error Try another predict cycle. If the problem persists contact
Welch Allyn Customer Care.
26 à
Invalid SureTemp mode Try another predict cycle. If the problem persists contact Welch Allyn Customer Care.
29 à
Battery Voltage Is Not Set Try another predict cycle. If the problem persists
contact Welch Allyn Customer Care.
30 à
Prediction mode Is Not Set Try another predict cycle. If the problem persists contact Welch Allyn Customer Care.
71 à
Device EEPROM acquire failure. Try
another predict cycle. If the problem
persists contact Welch Allyn Customer Care.
72 à
Device EEPROM release failure. Try
another predict cycle. If the problem
persists contact Welch Allyn Customer Care.
73 à
DEVICES EEPROM invalid pointer failure.
Try another predict cycle. If
the problem persists contact Welch Allyn Customer Care.
b^ à
Battery voltage too high. Replace the batteries with batteries that provide
less then 5.50 volts to the SureTemp Plus.
bv à
Battery voltage too low. Replace the batteries with new batteries. If problem does not go away and the
batteries are known as good (>= 3.1 volts applied) contact Welch Allyn
Customer Care.
A^! à
Ambient temperature too high. Move into
an area where the temperature is between 50ºF/10ºC and 110ºF/43.3ºC and allow
the thermometer to stabilize to ambient temperature. If problem persists replace the probe or contact Welch Allyn Customer
Care.
Av! à
Ambient temperature too low. Move into
an area where the temperature is between 50ºF/10ºC and 110ºF/43.3ºC. If the problem persists replace the probe or
contact Welch Allyn Customer Care. Patient
Temperature out of range. < 80ºF/26.7ºC or > 110ºF/43.3ºC. Make sure the probe is positioned properly
within the patient body site, with good tissue contact, and/or verify the
patient's temperature is in the range. Try
another temperature cycle with the probe positioned properly. If the problem persists, replace the probe
or contact Welch Allyn Customer Care.
Instrument Errors
Instrument Circuitry errors are generated from internal test
failures. Instrument errors are displayed as an instrument with an X through it
and an error code in the temperature field. In most cases this will
represent a broken instrument that needs replacing and the code will tell what
error was detected.
Probe Errors
The probe or probe connector can
generate errors. Probe
errors are displayed as a probe with an X through it and an error code
in the temperature field. In most cases this will represent a
broken probe that needs replacing and the code will tell what error was
detected. Temperature measuring is prohibited until the error is
cleared.
Patient Temperature Out of Range
Patient Temperature Out of Range errors
occur when the
patient temperature is above 110.0° F or below 80.0° F. During this
error, the entire body (head, torso, and legs) displays by blinking
with a solid up or down arrow and a thermometer bulb.
Ambient Temperature Out of Range
Ambient Temperature errors occur when the ambient probe
temperature is above 104.0° F or below 50.0° F. During an ambient temperature
error, the display in the temperature number field shows a capital “A” followed
by a blinking up or down arrow and a blinking thermometer bulb.
