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 continu­ously 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 concern­ing 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
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. 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. Remove the probe from the storage channel.

5. Observe the LCD to see that all display

segments appear followed by the display
of the probe type rEC = Rectal and tem­perature 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.

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 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.

• Monitor Mode: Monitor mode is generally used for long term (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.

functioning properly. Contact the Welch Allyn Customer Service
Department.

Broken Probe: If displayed, probe may be damaged. Remove and
reinstall probe. If error persists, then install a new probe.

Mode Table

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. It is recommended that a
new temperature be taken.

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, or when difficult situations prevent accurate
temperatures from being taken in the Normal mode.

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. 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 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. Lift the tail of the patient with one hand.
Using the other hand, gently insert the
probe only 3/4 inch inside the rectal sphinc­ter (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 measure­ment 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. Insert the probe into the storage channel to
clear the display, in preparation for an­other temperature.

9. Wash hands (note: washing hands greatly reduces the risk of cross­contamination and NSI).

Note: When using the Monitor mode, allow the temperature readout to stabilize
for 3 minutes

USING MONITOR MODE

Remove the probe from
the storage channel and
take a temperature.
After the temperature
is displayed, depress the
Mode button for more
than 2 seconds. The
“M” icon will appear
on the LCD indicating
the unit is in Monitor
mode. The unit is ready
to continuously display
temperatures in Monitor mode. After the Monitor mode temperature has been
taken, replacing the probe in the storage channel clears the display and resets
the thermometer to Normal mode. The unit will automatically enter the Monitor
mode by removing the probe from the probe storage channel and waiting 60
seconds.

NOTE: When using the Monitor mode, allow the temperature readout
to stabilize for 3 minutes for rectal temperatures .

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. Refer to the 679 SureTemp Technical 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 thermom­eter 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.
