Operating Instructions
Taking a Temperature Measurement
- Ensure you have had at least 3-4 hours of uninterrupted sleep.
- Take your temperature immediately upon waking, before getting out of bed, eating, drinking, or engaging in any activity.
- Press the power button to turn on the thermometer. The display will show 'Lo' (indicating it's ready to measure a low temperature) and then briefly flash the last recorded temperature.
- Place the thermometer tip under your tongue, ensuring good contact with the tissue. Close your mouth and hold the thermometer in place.
- Keep your mouth closed and remain still. The thermometer will take approximately 60 seconds to register the peak temperature.
- Four short beep tones will sound when the measurement is complete and the temperature has stabilized.
- Remove the thermometer and read the temperature displayed on the LCD screen.
- Press the power button to turn off the thermometer, or it will automatically shut off after a period of inactivity.

Memory Recall
To view the last recorded temperature:
- When the thermometer is off, press and hold the power button.
- The last temperature reading will be displayed on the screen for as long as you hold the button.
- Release the button to return to the normal measurement mode or turn off the device.
Basal Body Temperature (BBT) Tracking
Charting your BBT can help identify your ovulation window. A slight increase in basal body temperature (typically 0.4 to 1.0°F) often occurs after ovulation and remains elevated until your next menstrual period. Consistent daily measurement is key.
- Record your temperature on a dedicated BBT chart each morning. The included 12-month ovulation charts are designed for this purpose.
- Look for a sustained temperature shift (three consecutive days of higher temperatures than the previous six days) to confirm ovulation.
- Factors such as illness, stress, alcohol consumption, and inconsistent sleep can affect BBT readings. Try to maintain consistent conditions for measurement.

Maintenance
Cleaning
To ensure hygiene and accurate readings, clean the thermometer before and after each use:
- Wipe the thermometer tip and body with a soft cloth dampened with rubbing alcohol (70% isopropyl alcohol) or an antiseptic wipe.
- Do not immerse the entire thermometer in water or any cleaning solution. The thermometer is not waterproof.
- Allow the thermometer to air dry completely before storing it.
Storage
Store the thermometer in its clear plastic storage case when not in use. Keep it in a cool, dry place, away from direct sunlight and extreme temperatures.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display shows 'Lo' and does not change. | The thermometer is ready to measure a temperature lower than its initial reading range, or it is not properly placed. This does not indicate a low battery. | Ensure the thermometer tip is correctly positioned under the tongue with the mouth closed. Wait for the measurement to complete (approx. 60 seconds). |
| Inaccurate or inconsistent readings. | Improper placement, movement during measurement, recent activity (eating, drinking, talking), or illness. | Ensure consistent measurement conditions: take temperature immediately upon waking, before any activity, and with proper placement. If ill, note this on your chart. |
| Thermometer does not turn on. | Dead or improperly installed battery. | Check battery installation. Replace with a new LR41 battery if necessary. |
| Battery cap comes off easily. | Normal wear or slight manufacturing variation. | Ensure the cap is twisted and pushed firmly into place after battery changes. Handle with care. |
