INTRODUCTION
The Welch Allyn 679V 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). Rectal probes utilize single-use disposable
probe covers which limit cross-contamination. Rectal temperatures are
taken using Normal or Monitor operating modes. In the Normal mode,
the thermometer’s microprocessor “predicts”body temperature in about
in about 15 seconds for rectal temperatures. The Monitor mode continu-
ously displays the temperature of the probe which will reflect the
patient’s actual temperature in about 3 minutes and will continue for as
long as the probe remains in place.
SAFETY& WARNINGS
DO NOT USE IN THE PRESENCE OF FLAMMABLE
ANESTHETICS.
Caution: Federal (USA) law restricts this device to sale by or on the order of
a physician.
In order to obtain accurate and reliable temperature-taking results and ensure
patient safety, it is important that this booklet be read thoroughly prior to
using the instrument. If you have any technical or clinical questions concern-
ing the thermometer’s use and/or care, please contact our Customer Service
Department at [phone].
•Single-use disposable probe covers, available from Welch Allyn, will
limit patient cross-contamination. The use of any other probe cover or
the failure to use a probe cover may produce temperature errors and will
invalidate the instrument’s warranty.
•Rectal probes (red ejection button) are to be used for taking rectal
temperatures only. The use of the wrong probe will produce temperature
errors.
•The thermometer case is not waterproof; do not drip fluids onto it.
•Do not use this instrument for any purpose other than that specified in
this booklet. Doing so will invalidate the instrument’s warranty.
•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
679V SureTemp technical manual.

WALL MOUNTING INSTRUCTIONS
The optional wall mount bracket should be mounted approximately 48 inches
fromthefloor. Thisallowstheenduserofaverageheightrelativelyeasyaccess
to the probe and probe covers. It should have at least 12 inches of clearance on
thetopofthe unitso thatthe enduser caneasily removethe thermometerprobe
and load a probe cover without hindrance. Clearance of at least 4 inches from
the bottom of the unit and from either side is also advisable to prevent tangling
of the probe cord with other equipment at the bedside.
The wall mount bracket should be mounted in a location so that when a
thermometer is installed, the display can be read easily. Placement should
also ensure that the probe can be readily removed from the thermometer, a
probe cover can be easily installed and the probe can be returned to its
position without stress being placed on either the instrument, the wall mount
or most importantly, the patient.

SETUP
1. Install the supplied Rectal probe by inserting the latching plug on the end of
the coiled cord into the plug receptacle on the unit. The plug snaps into
place and cannot be removed without
depressing the latch. (Figure 1).
2. Observe the LCD to see that the probe type
rEC = Rectal is displayed.
3. Insert probe shaft completely into probe
storage channel.
4. Removetheprobefromthestoragechannel.
5. Observe the LCD to see that all display
segments appear followed by the display
of the probe type rEC = Rectal and tem-
perature scale (°C or °F). Replace probe
in storage channel.
6. Insert a box of disposable probe covers
(part number 05031) into the probe
cover storage well.
CHANGINGPROBES
•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 rectal temperatures in about 15
seconds. The unit will always operate in Normal mode unless the Mode
button is depressed for more than 2 seconds after the initial temperature is
displayed which changes it to Monitor Mode. Replacing the probe in the
storage channel automatically resets the unit to Normal mode.
•MonitorMode: Monitormodeisgenerallyusedforlongterm(continuous)
temperature monitoring or when difficult situations prevent accurate
temperatures from being taken in the Normal mode.
•Rectal Probe with 4’coiled cord and latching plug.
•Optional Rectal Probe with 9’coiled cord and latching plug.
•Mode Button: Recalls the last Normal mode temperature taken, converts
temperatures from °F to °C, switches the unit to Monitor Mode.

High Temperature: This icon is displayed if the patient’s temperature
is greater than 108.0°F (42.2°C).
Low Temperature: This icon is displayed if the patient’s temperature
is less than 84.0°F (28.9°C).
High Ambient Temperature: This icon is displayed if the ambient
temperature is greater than 104°F (40°C).
Low Ambient Temperature: This icon is displayed if the ambient
temperature is less than 60.8°F (16.0°C).
Low Battery: This icon is flashes when batteries are low and will
remain on when batteries are dead.
Display Test: All segments of the thermometer display will appear
briefly when the probe is removed from the storage channel to ensure
proper function.
OPERATION
1. Withdrawtheprobefromthestoragechan-
nel and observe a thermometer display
test followed by an audible tone and a
display of the probe type rEC = Rectal.
2. Load a probe cover onto the probe. Hold
probe handle collar with thumb and fore-
finger, being careful not to hold or press
the “ejection”button. Press the collar
down firmly to secure the cover.

3. Lift the tail of the patient with one hand.
Using the other hand, gently insert the
probeonly3/4inchinsidetherectalsphinc-
ter (less for patients under 20 lbs.). The
use of lubricant is optional.
WARNING: Incorrect insertion can
cause bowel perforation.
4. Hold the probe in a stable position during the entire temperature measure-
ment cycle. It is important that there be no probe movement during the 15
second measurement cycle to assure accurate results. An assistant may be
necessary to control difficult patients.
5. During the temperature measurement
cycle, “walking”segments will appear on
the display indicating measurement is in
process.
6. When the final temperature is reached, a
tone will sound and the temperature will
be displayed.
7. 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).
8. Inserttheprobeintothestoragechannelto
clear the display, in preparation for an-
other temperature.
9. Wash hands (note: washing hands greatly reduces the risk of cross-
contamination and NSI).

MAINTENANCE
Other than using a new probe cover for each temperature reading, keeping the
instrument clean, and replacing the batteries, there is no requirement for user
maintenance. Referto the 679 SureTempTechnical Service Manual for detailed
information on security settings, sterilization, and calibration verification.
Battery Replacement
1. With thumb and forefinger, firmly
press-in on indentations located on the
sides of the rear housing. This will
release two snaps.
2. Remove the battery door.
3. Remove batteries. IMPORTANT:
After removing the old batteries press
and hold the MODE button for 5
seconds before inserting the new
batteries.
4. Replace batteries with AA Alkaline only, orienting per markings on the
8

inside of the battery well.
5. Replace the battery door by inserting two tabs into bottom of thermom-
eter and snapping back into place.
CLEANING& STERILIZATION
The 679V SureTemp housings may be cleaned with a cloth dampened with
alcohol, warm water, or a nonstaining disinfectant such as Sporicidin®Spray
and Towelettes or MetriSpray™. Care should be taken not to scratch the LCD
faceplate. Low temperature Ethylene Oxide (ETO) sterilization of Oral or
Rectal probes is to be used only when absolutely necessary. The procedure for
ETO sterilization is described in the 679 SureTemp Technical Service Manual
and is available from Customer Service.
