DMT-77BT
The device is intended for measuring body temperature
via forehead and ear, and measuring ambient/object temperature.
Do not use this device for anything other than its intended purpose.

Forehead measurements

How to do a forehead measurement:
1
Point the forehead
thermometer towards
the middle of the
forehead at around
1 inch distance.
Since forehead temperature fluctuates and can be influenced by outside factors, the DMT-77BT
carefully calculates the ambient temperature before measuring. It takes a second longer to receive
your first result, and then gives you the most accurate measurement possible.
Why does forehead temperature fluctuate?
Your forehead is not protected from outside influences. Walking outside on a cold winter day or
a hot summer day can change the temperature of your forehead very easily, way easier than the
temperature inside your ear. Washing your face will also influence the temperature. This is why we
are so proud that this device can measure your body temperature via the forehead. The DMT-77BT
calibrates first, to get the most accurate reading possible.
Want to be 100% sure no external factors have influenced your temperature reading?
Do an ear measurement as well!

Ear measurements

How to do an ear measurement:
1
Take off the cap of the
thermometer to switch
to ear mode. Press the
main button.
The sensor measures the temperature of your eardrum. Since your eardrum lays deep inside your
ear it is a great place to measure your body temperature. It does not get influenced by outside
factors. The thermometer does not need to be calibrated for an ear measurement. Earwax might
obstruct the infrared reading of your eardrum. If you have a lot of earwax, take a forehead measure-
ment for a more accurate result. If you have an ear infection there is a high chance the temperature
of your eardrum will be warmer than your actual body temperature. In case of an ear infection, do a
forehead measurement instead.
Ear temperature measurement is recognized as highly accurate by doctors and used in hos-
pitals around the world. At iProven we decided to combine this clinically accurate way of
measuring with the quick and easy no-touch forehead method.

Things that can influence your body temperature:

- Taking a shower or bath
- Exercising
- Powerful emotions
- Sunbathing
- Being outside in wind and/or rainy weather
To make sure you measure your true body temperature when any of the above occurs, relax
and wait 20 minutes before measuring.

More advice on accuracy

The sensor of the DMT-77BT is basically like a
little camera that 'sees' temperature. To make sure
it's able to read your temperature correctly, it is
important to keep the lens clean. An obstructed
lens can make your reading inaccurate.
How to clean the lens:
Before cleaning, always remove the batteries from the device. Take a microfiber cloth and make it
slightly wet. Carefully remove any dirt off the lens surface. You can use a cotton swab or the corner
of the cloth to cautiously remove any dirt stuck to the edges of the lens.

Warning:
Don't use any abrasive cleaning products. Do not immerse the device in liquid. If you want to
use a disinfectant, we recommend Isopropyl alcohol solution (concentration: 70%) or Medicinal
alcohol (concentration: 75%).
