Omron Digital BBT Thermometer

How to Take Accurate Temperatures. To obtain an accurate basal temperature, you must take your temperature immediately upon awakening in the morning. For best results, your temperature should be taken at the same time each morning. Any activity may raise your temperature, so don't get out of bed until after you've taken your temperature. Don't go to the bathroom, don't eat or drink anything, and don't smoke until after taking your temperature. Cold drinks lower mouth temperature; hot drinks, smoking and exercise cause higher temperatures. Using an electric blanket or heating pad can affect your temperature. If you do use one, it should be kept at the same setting each night throughout the time you are taking your temperature (i.e., every day for the entire month).

Should You Use the Oral, Vaginal or Rectal Method? Since temperatures taken at different sites can vary, it is important to select one method and then always take your temperature the same way. You must use either the oral, vaginal or rectal method, but should never alternate between any of the methods. Using more than one method will provide inaccurate results.

Taking Your Basal Temperature – Oral Method

	Place a disposable probe cover over the tip.
	Push the on/off button located beside the display window. Hold the button down to recall the last measured temperature. The thermometer will beep and the display will read: "188.8°F M". This is a function check indicating the thermometer is working properly. Next, the thermometer will read "L°F".
	The °F symbol will flash continuously when the thermometer is ready to be used. Please note that the upside-down triangle symbol indicates a low battery. See instructions for replacing the battery (below). Do not expect an accurate temperature reading if this low battery indicator is present. An "Err" message in the window indicates that the thermometer is not functioning properly.
	Don't drink or eat anything, exercise, smoke or perform any other activities before taking your temperature.
	Place the sensor tip well under the tongue.
	When the peak temperature is reached, the °F symbol will stop flashing, and the thermometer will beep repeatedly. NOTE: It is not necessary to hear the beep to ensure the peak temperature has been reached. When the °F symbol stops flashing and the display reads a consistent temperature, the peak temperature has been reached.
	Read and record the temperature and time for reference. The result will automatically be stored in the memory.
	Push the on/off button to turn the thermometer off. If you forget to turn off the thermometer, it will shut off automatically in approximately 10 minutes.

Taking Your Basal Temperature – Vaginal Method. Please seek guidance from your health care professional.

Taking Your Basal Temperature – Rectal Method. Lubricate the tip of the thermometer with a water-soluble lubricant or petroleum jelly. Lie on your side with knees slightly bent. With one hand, gently slide the tip of the thermometer no more than 1/2-inch into the rectum. Once used rectally, the thermometer should not be used orally or vaginally (for sanitary reasons).

Caring for Your Basal Thermometer. Before and after each use, wash the tip of the thermometer with warm (not hot) soapy water, or wipe the area with isopropyl alcohol. It's easier to use a "disposable probe cover" every time a temperature is taken. (You can purchase digital probe covers here.)

Changing the Battery. When the upside-down arrow symbol appears in the lower right of the display, the battery is depleted and must be replaced. Remove the battery compartment lid. Use a small Phillips screwdriver to remove the battery. Insert a new equivalent battery type (1.5V, SF41). (You can purchase batteries here.) Ensure that the battery is correctly positioned with the "+" facing up or towards the back of the unit. Carefully replace the battery compartment lid. Ensure that the "O"-ring (washer) is in place to maintain water resistance. Properly dispose of the batteries according to local regulations, and keep them away from small children and heat. WARNING: KEEP BATTERIES OUT OF REACH OF CHILDREN. SWALLOWING BATTERIES COULD BE HARMFUL. BATTERIES SHOULD NOT BE CHARGED OR PLACED INTO EXTREME HEAT, AS THEY MAY EXPLODE.
