Cleaning
• Clean Teena before and after every use.
• Use a damp cloth to carefully clean the sensor on your
Teena. You can also use a little alcohol or soap if you
wish. Since your Teena is not waterproof, make sure that
only the neck of the sensor, and not the whole device,
comes into contact with water. Do not clean under
running water.
Battery
• The battery does not need to be charged or
replaced since Teena is a low power device.
Under ideal conditions the battery lasts up
to 7 years or more.
Error messages / Problems during use
My Teena does not respond when I touch the touch field. Please contact our Customer Support.
Teena flashes alternately red and turquoise. Please synchronize your Teena and contact our Customer Support.
My Teena flashes turquoise as soon as I turn it on. The flashing turquoise light means you have already successfully
taken a measurement today, or if your Teena is new, you must sync to the app to activate your Teena and create an account.
The indicator light flashes a few times orange and changes to slowly flashing turquoise before I can place Teena under my
tongue. Please synchronize and contact Customer Support.
My Teena ends the measurement with a alternately flashing
orange and turquoise light instead of a slowly flashing tur-
quoise light.
The measurement took too long, was interrupted, or was
unsuccessful. Try following these tips:
• As before, place the sensor as far back as is comfortable
under the right or left side of your tongue.
• Close your mouth.
• Do not remove your Teena from your mouth until you see
the slowly flashing turquoise light.
• Teena may not accept the measurement if you have a
fever. Stop taking measurements if you are sick.
• If the sensor gets dirty, simply clean it with a damp cloth.
