Important Safety Information
- This thermometer is not a toy. Keep it out of a child's reach when not in use.
- Do not allow children to walk or run with the thermometer.
- Do not bite or chew the thermometer.
- Do not bite the sensor tip while taking oral temperatures. Simply place the tip under the tongue.
- Avoid exposing the thermometer to direct sunlight, high temperatures, or dirt.
- Do not modify this equipment without manufacturer authorization.
- Dispose of the unit, accessories, and batteries according to national requirements.
- Cross-contamination may occur if the device is not sanitized after rectal use, or if not disinfected before use.
- Do not dismantle the thermometer for any reason other than battery replacement.
- WARNING: BATTERY IS DANGEROUS. KEEP OUT OF REACH OF CHILDREN. SWALLOWING A BATTERY COULD BE FATAL. BATTERY SHOULD NOT BE CHARGED OR PLACED INTO EXTREMELY HOT/COLD CONDITIONS, AS IT MAY EXPLODE.
Setup and Initial Use
- Battery Installation: The thermometer comes with a battery installed. If the battery symbol appears on the display, refer to the 'Replacing the Battery' section.
- Initial Cleaning: Before first use, clean the thermometer tip thoroughly with rubbing alcohol and a cotton swab.
- Power On: Press the power button. The last measured temperature will be displayed, indicated by an "M" under the degree sign. Several readings may be displayed until the thermometer is ready for use.
- Ready for Measurement: When "F/C" appears in the display, the thermometer is ready to take a reading. Note that this model primarily displays in Fahrenheit, and instructions for changing units are not provided in this manual.
Operating Instructions
Ensure the thermometer tip is clean before each use.

Oral Use
- Place the sensor tip under the tongue.
- Hold the thermometer in place for approximately 60 seconds.
- When the peak temperature is reached, the "F/C" indicator will stop flashing, and a beep will sound.
- Read the final temperature displayed on the digital screen.
Underarm Use
- Place the sensor tip under the armpit and gently hold it in place.
- Hold the thermometer in place for approximately 2-4 minutes.
- When the peak temperature is reached, the "F/C" indicator will stop flashing, and a beep will sound.
- Read the final temperature displayed on the digital screen.
Rectal Use
- Apply a water-soluble jelly to the thermometer tip to ease insertion. Do not use petroleum jelly.
- Place the child across your lap and spread to expose the rectum.
- Insert the tip approximately 1/2 inch. If you detect any resistance, stop insertion immediately.
- Hold the thermometer in place for approximately 60 seconds.
- When the peak temperature is reached, the "F/C" indicator will stop flashing, and a beep will sound.
- Read the final temperature displayed on the digital screen.

Maintenance and Care
Cleaning
- Before and after each use, clean the thermometer tip thoroughly with rubbing alcohol and a cotton swab.
- The waterproof tip allows for easy cleaning.
- Do not immerse the entire thermometer in water or cleaning solutions.
Storage
- Store the thermometer in its hygienic cover when not in use.
- Store in a cool, dry place, away from direct sunlight and high temperatures.
Replacing the Battery
When the battery is nearly exhausted, a battery symbol will appear in the display window.
- Use a toothpick or an insulated probe to carefully remove the old battery.
- Insert a new 1.55 VDC (LR41) battery. Ensure the positive side (+) is facing up and the negative side (-) is facing down.
Troubleshooting
- "Lo" Display: If the display shows "Lo" (less than 90.0°F/32.0°C), it indicates the measured temperature is below the measurable range. This is normal if the thermometer is not in contact with a heat source.
- "Hi" Display: If the display shows "Hi" (more than 109.9°F/42.9°C), it indicates the measured temperature is above the measurable range.
- Slow Readings: Ensure proper placement and contact with the body part for the recommended duration (e.g., 60 seconds for oral/rectal, 2-4 minutes for underarm).
- Battery Symbol Displayed: Replace the battery as described in the 'Replacing the Battery' section.
- No Display/Malfunction: Ensure the battery is correctly installed and charged. If the issue persists, contact customer support.
