INTRODUCTION The Welch Allyn 679 SureTemp is a portable thermistor thermometer to be used for measuring patient temperatures ranging from 84°F to 108°F (28.9°C to 42.2°C). Oral/axillary and rectal probes utilize single-use disposable probe covers which limit cross-contamination. Oral, axillary and rectal temperatures can be taken using Normal or Monitor operating modes. Axillary temperatures taken using the Normal operating mode will display temperatures in about 10 seconds for patients 3 years and under.
• Do not use the thermometer if you notice any signs of damage to the probe or instrument. Contact our Customer Service Department for immediate assistance. • Do not ETO sterilize without using proper procedures described in the 679 SureTemp technical manual. Figure 1 1.

WALL MOUNTING INSTRUCTIONS The optional wall mount bracket should be mounted approximately 48 inches from the floor. This allows the end user of average height relatively easy access to the probe and probe covers. It should have at least 12 inches of clearance on the top of the unit so that the end user can easily remove the thermometer probe and load a probe cover without hindrance.
CHANGING PROBES • Depress the latch and unplug the probe connector from the thermometer. • Remove the probe from the storage channel. • Repeat steps 1 through 6 in the SETUP section. FEATURES • Normal Mode: The thermometer takes oral temperatures in about 4 seconds and rectal temperatures in about 15 seconds. Axillary temperatures taken using the Normal operating mode will display temperatures in about 10 seconds for patients under 4 years.

Broken Probe: If displayed, probe may be damaged. Remove and reinstall probe. If error persists, then install a new probe. Probe Position: Probe has broken contact with the tissue. Once proper contact has been achieved, the icon will be turned off but will reappear at the end of the temperature measurement.
or Rectal Probe: This icon is displayed to show that the rectal mode has been selected. Walking Segments: This will be displayed when the thermometer is in process of taking a temperature in the Normal mode. Monitor Mode: Monitor mode is generally used for long term temperature monitoring, taking axillary temperatures, or when difficult situations prevent accurate temperatures from being taken in the Normal mode. High Temperature: This icon is displayed if the patient’s temperature is greater than 108.
OPERATION 1. Withdraw the probe from the storage channel and observe a thermometer display test followed by an audible tone and a display of the probe type OrL = Oral, ALy=Axillary, or rEC = Rectal. 2. Load a probe cover onto the probe. Hold probe handle collar with thumb and forefinger, being careful not to hold or press the “ejection” button. Press the collar down firmly to secure the cover.
3. During the temperature measurement cycle, “walking” segments will appear on the display indicating measurement is in process. 4. When the final temperature has been reached, a tone will sound and the patient’s temperature will be displayed. 5. After the temperature measurement is complete, remove the probe from the patient, then eject the probe cover by firmly pressing the ejection button on the probe. (Figure 1) 6.
TAKING AXILLARY TEMPERATURES (PATIENTS UNDER 4 YEARS) BLUE CAPPED PROBE Axillary temperature in children ages’ birth through three years can be taken with the SureTemp in the Axillary Mode, with an oral probe. 1.
