1. Ensure that the rectal probe (red ejection button) and the red probe well are
installed. The instrument will only operate in Rectal Mode when the red rectal probe
and probe well are installed.
2. Holding the probe handle with your thumb and two fingers on the indentations of the
probe handle, withdraw the probe from the probe well.
3. Observe the flashing lower-body icon on the unit's display. Load a probe cover by
inserting the probe into a probe cover and pressing the probe handle down
firmly. The probe handle will move slightly to engage the probe cover.
4. With the Rectal Mode indicator flashing, separate the patient's buttocks with one
hand. Using the other hand, gently insert the probe only 1.5 cm (5/8 in.) inside the
rectum (less for infants and children). The use of a lubricant is optional.
5. Tilt the probe so that the tip of the probe is in contact with tissue. Keep the hand
separating the buttocks in place, and hold the probe in place throughout the
measurement process. Rotating "walking" segments appear on the display,
indicating that measurement is in progress.
6. The unit will beep three times when the final temperature is reached. The
measurement site, temperature scale, and patient temperature will display on the
LCD. The final temperature will remain on the display for 30 seconds.
7. If you cannot correctly measure the patient's temperature in Normal
Mode, the unit will automatically enter Monitor Mode. In this mode,
measurement time is extended. Either repeat the temperature
measurement in Normal Mode or keep the probe in place for three
minutes in Monitor Mode. The thermometer will not beep to indicate a
final temperature. Record the temperature before removing the probe from the site,
as the temperature reading is not maintained in memory.
8. After the temperature measurement is complete, remove the probe from the
patient's rectum. Eject the probe cover by firmly pressing the ejection button on the
top of the probe.
9. Return the probe to the probe well. The LCD display will go blank.
WARNING Cross contamination or nosocomial infection risk. Thorough hand-
washing greatly reduces the risk of cross-contamination and nosocomial
infection.
WARNING Do not take a patient's temperature without using a Welch Allyn
disposable probe cover. Doing so can cause patient discomfort, patient cross
contamination, and erroneous temperature readings.
WARNING Use only Welch Allyn probe covers. The use of other
manufacturer's probe covers or no probe cover may produce temperature
measurement errors and/or inaccuracy.
WARNING Patient injury risk. When taking rectal temperatures, insert the
probe tip only 5/8 inch (approximately 1.5 cm) inside the rectum of adults and
only 3/8 inch (approximately 1 cm) inside the rectum of children to avoid the
risk of bowel perforation.
WARNING Long-term continuous monitoring beyond three minutes is not
recommended in Rectal Mode.
