Medel Fertyl - Digital Thermometer Manual

The basal thermometer

Measuring your basal temperature

Take your temperature at the same time, as soon as you wake up and before you get out of bed. You should have slept for at least 4 hours before the measurement. If you have slept for less than 4 hours before the measurement, enter the amount of sleep you have had in the Ovy app or activate „Disrupted sleep". Do not eat anything before the measurement and avoid physical exertion.
You can make oral, rectal or vaginal measurements, but you should always take the measurements in the same place in a cycle. We recommend taking the measurement under your tongue with your mouth closed.
The thermometer should not be changed during the cycle. If you change the thermometer during the cycle, you must also note it as a disruption, just like a change to the place of measurement. For this cycle, a reliable evaluation is then no longer guaranteed.

	Press the On/Off button to switch on the device. A short acoustic signal will announce that the thermometer is switched on. The thermometer will carry out a self-test for about 2 seconds. During the selftest all segments of the display will appear.
	Then the reference reading 36,50°C appears. Then the measurement symbol "°C" flashes and "Lo" is shown on the display. The thermometer is now ready for use. Insert the tip of the sensor into one of the two heat pockets under your tongue, to the left or right of the root of your tongue. The measurement sensor must have good contact with tissue.

Close your mouth and breath calmly through your nose so that the air from your breathing does not influence the measurement. During the measurement, the current temperature is displayed continuously, and the "°C" symbol flashes on and off. The measurement is completed when a stable temperature has been reached. When this stage has been reached, an acoustic signal is heard, the "°C" symbol stops flashing and the temperature measured is displayed. We recommend a measuring time of 3 minutes. If the temperature stability is reached earlier, the acoustic signal sounds. Please always wait until the end of the measurement before you remove the thermometer from the place of measurement. The measured value is saved until the next measurement. The device switches off automatically approx. 10 minutes after the end of the measurement. You can also switch off the thermometer before this time by pressing the On/Off button.

Memory

The last measured value is automatically saved. To display this value, press the On/Off button for more than 2 seconds. The last measured value is then shown. Once the button is released, the reference value of 36,50°C and "Lo" are shown on the display. The thermometer is ready to take a measurement and the previously stored measured value is automatically replaced by the new measured value.

Replacing the battery

1. Replace the battery when the battery status indicator appears on the display:
   
2. Slide back the battery compartment cover to remove it.
3. Pull the battery holder carefully out of the housing by approx. 1 cm.

Technical data

The Ovy app is free for iOS and Android^TM

The Ovy app enables you to record your entire cycle and keep an eye on it at any time on your smartphone. Ovy is designed for women who want to have children. The app is available to download for free in the Apple App Store and Google Play. The Ovy app is a certified Class 1 medical device.

How does Ovy work?

The Ovy app works out your cycle automatically, without pen and paper. This includes your period, ovulation and your fertile and non-fertile windows. To do this, take your temperature when you wake up in the morning and enter this value (to two decimal places) in the Ovy app. To make the prediction even more accurate, add other body signals each day. You should ideally start recording this on the first day of your period; i.e. the first day of your menstrual cycle. However, you can also start recording on any day in your cycle. It is important that you record when potential external temperature influences such as a fever, consumption of alcohol or a lack of sleep have occurred.
You can also enter your basal temperature, body signals and influencing factors at a later time, but the temperature measurement should have been taken on the relevant day. The Ovy app is based on a self-learning algorithm. This means that the more often you enter your basal temperature, the more accurately Ovy will be able to predict your fertile days and your next period.
