What is the best technique for taking a temperature?
In order to perform the proper temperature technique, gently pull back the earlobe before inserting the thermometer for best results. Tugging on the earlobe provides a direct line to the ear drum to maximize the accuracy of results. Insert thermometer into the ear, press the "On" button. Gently rock the thermometer back and forth so that the probe tip scans the ear drum. Listen for the ready beep and then press the "On" button again for measurement. Four beeps indicate measurement is complete which takes 1 second. A poor technique can cause low readings.

How do I keep the device clean?
Wipe off the casing of the unit with a soft, dry cloth, or with rubbing alcohol. When dirty, clean the lens only using a soft, dry cloth or cotton swab. Do not clean ANY part of the unit with detergent, thinner, or benzene. Do not immerse in water. After use, be sure to discard used lens, and replace with a new one, so that the unit is ready for use again.

What do the following "display" messages mean?

PC - The Lens/Probe Cover is not on the Probe. Attach the Lens/Probe Cover, then take a measurement.

AA - Temperature of the unit is unstable. Make sure the unit remains at the room temperature where measurement will take place. Allow 30 minutes to stabilize before using. Normal operating range: 50° F to 104°F (10°C to 40°C).

AL - The temperature of the unit is 50° or below which is outside the operating range. Make sure the unit remains at room temperature where the measurement will take place. Allow 30 minutes to stabilize before using. Normal operating range: 50° F to 104°F(10°C to 40°C).

AH - The temperature of the unit is 104° or above which is outside the operating range. Make sure unit remains at room temperature where the measurement will take place. Allow 30 minutes to stabilize before using. Normal operating range: 50° F to 104°F(10°C to 40°C).

Er.1 - Service may be required. Turn on the unit again. If "Er.1" is displayed again, the unit may require service. Call the Service Department at 1-800-634-4350.

H - The measured temperature was above the range of the thermometer. The Probe may not have been properly positioned in the ear. The probe must be snug against opening of the ear. Be sure the lens cover is clean and the ear canal is not blocked with earwax.

L - The measured temperature was below the range of the thermometer. The Probe may not have been properly positioned in the ear. The probe must be snug against opening of the ear. Be sure the lens cover is clean and ear canal is not blocked with earwax.

"F" or "C" Flashes with battery symbol - Indicates low battery. Replace with new battery. Replace with DC 3 Volt (Lithium battery CR2032).

Can I hurt the eardrum of a child by inserting the ear thermometer?
The probe has been designed to ensure proper fit in the ear. You can place the probe firmly into the ear canal without risk of harming the eardrum of even the smallest child.

Is the ear thermometer accurate?
Clinical research has shown that the ear is an ideal site for taking body temperature. The eardrum shares blood vessels with the hypothalamus, the part of the brain that controls body temperature. Therefore, the ear is an accurate indicator of internal body(core) temperature. An ear temperature, unlike an oral temperature, is unaffected by factors such as talking, drinking, and smoking.

We recommend that you practice with the ear thermometer on yourself and family members when you are healthy. This way you can improve your technique and feel more confident of the measurements you take when a family member is ill.
