How to Use:

  1. Disinfect the probe with isopropyl (rubbing) alcohol before using.
  2. Press and release the multifunction button. The display will read confirming the unit is functioning properly. The last measured temperature will be displayed for approximately 2 seconds. Next the thermometer will read - - - °F, (or - - -C°).
  3. We recommend using probe covers with all digital stick thermometers. If using, place cover over tip of unit.
  4. Place the probe in the appropriate position for your measurement site (see Ensuring Accurate Temperature Measurement below).
  5. The °F or °C symbol will flash when the unit is ready to measure temperature. Please note that the “ ” indicates a low battery. See instructions for replacing battery before measuring temperature. Do not expect an accurate temperature reading if this low battery indicator is present. An “ERR” message in the window indicates your unit is not functioning properly.
  6. Depending on the measurement site, the unit will complete measurement in approximately 30-40 (oral), 25-35 (rectal), or 90 (axillary) seconds. The display will flash and the unit will beep signaling completion.
  7. Read and record the temperature and time for reference. The reading will automatically be stored in the memory.
  8. The unit will automatically turn off in about 8 minutes. To prolong battery life, press the multifuction button to turn off the device manually.

Switching Temperature Modes

From the OFF position, the Celsius or Fahrenheit mode can be switched by pressing and holding the multifunction button for at least 5 seconds. After 3 seconds in one scale the °F or °C will flash, indicating ready to measure.

Ensuring Accurate Temperature Measurement

We recommend using probe covers with all digital stick thermometers (Figure 1).

Oral use: Place the probe well under the patient’s tongue (Figure 2). Keep mouth closed while thermometer is reading. Instruct children not to bite down on the probe. The peak temperature should be reached in as little as 30* seconds. Opening the mouth or improper placement of the probe tip could result in a longer time for a reading. (*30 second response time achieved in water bath test)

Rectal Use: Lubricate the probe cover with a water-soluable jelly for easier insertion; do not use petroleum jelly, as it may cause an inaccurate reading. Gently insert the tip of the probe no more than 1/2 inch into the rectum.

STOP if you meet any resistance. The sensing unit is on the very tip of the probe and there is no need to insert the probe deep into the rectum. Dispose of the used probe cover and wash the thermometer as recommended. The peak temperature should be reached in approximately 25-35 seconds.

Axillary Use: Wipe armpit with a dry towel. Place the probe in the patient’s armpit (Figure 3) and keep the patient’s arm pressed firmly against the body. In order to achieve a better axillary reading, a minimum measuring time of 90 seconds or longer is recommended, depending on placement of the probe and closure of the arm against the body.

Battery Replacement

  1. When the symbol “ ” appears, the battery needs to be replaced.
  2. Remove battery compartment lid (Figure 4).
  3. Use a pointed object such as a toothpick to pry loose the old battery. Avoid using any sharp metal object.
  4. Place new 1.55V coin-type battery (LR41 or equivalent) in the chamber with the positive (+) side facing up or towards the display of the unit.
  5. Replace the battery compartment lid.

Cleaning and Disinfecting

Do not use corrosive detergent to clean the unit.

Clean and disinfect the thermometer before and after each use.

Cleaning Process

1. Wipe probe with a cloth dipped in a disinfectant solution such as 70% isopropyl (rubbing) alcohol or soap and water.

2. Rinse off disinfectant residue.
