Note: Temperature measurement displays in this Directions For Use booklet are in °F. International units will display measurements in °C.
5. Insert the probe shaft into the probe storage channel (Fig. 1).
SETUP 1. Unpack the Welch Allyn Thermometer System. Check for any damage that may have occurred during shipping. 2. Select the desired probe (oral probe - green body, rectal probe - red body). 3. Insert the probe cord connector into the probe receptacle. Check that the connection is secure. 4. Observe the 7-second display test, ensuring that no display segments are missing (Fig. 2).
6. Remove the tab from a box of 25 Welch Allyn disposable probe covers and insert the box into the holder on the thermometer. OPERATION 1. Select the temperature measurement mode (normal or monitor - Fig. 3). Most temperatures are taken in the normal mode. 2. Withdraw the probe from the storage channel and observe the display test. The unit will then display 84.0°F (28.9°C) with the low temperature arrow ON until the probe temperature rises above 84.0°F (28.9°C).

3. Load a probe cover onto the probe. Hold the probe collar with thumb and forefinger, being careful not to hold or press the "eject" button. Press the collar down firmly to secure the cover (Fig. 4). 4. Take the temperature: FOR ORAL TEMPERATURES, insert the probe tip gently into the patient's slightly opened mouth. Carefully slide the probe under the tongue on either side of the mouth to reach the sublingual pocket. FOR RECTAL TEMPERATURES, gently insert the probe only 1 cm (3/8 of an inch) inside is
the rectal sphincter (less for infants and children). WARNING: Incorrect insertion can cause bowel perforation. (FIG. 5) Tilt the probe to insure good tissue contact and continue to keep buttocks separated until measurement cycle is complete. 5. During a temperature measurement cycle in the NORMAL mode, a continuously increasing temperature should be observed on the display. When the final temperature has been reached, a tone will sound and a temperature will be displayed. When using the MONITOR mode, allow the temperature readout to stabilize for 3 minutes. The patient may then be

continuously monitored for as long as necessary. 6. After the temperature measurement is complete, eject the probe cover by firmly pressing the "eject" button on the probe. (Fig. 1 ). 7. Insert the probe into the storage channel to clear the display, in preparation for another temperature. (Fig. 6). FEATURES 1. Two Temperature Measurement Modes. Normal mode provides a rapid means of oral or rectal temperature taking under most conditions. Monitor mode

generally used for long term monitoring or when difficult situations prevent accurate temperatures from being taken in the normal mode. SELF TESTS Two internal tests are activated each time a temperature is taken: 1. Calibration Check: an internal check for proper calibration. 2. Microprocessor Self Check: an internal check for proper microprocessor operation, including a test of the entire system.
