• You can take your temperature early in the morning right after waking up.
•Always take your temperature immediately after waking up, before getting up,
i.e. before becoming active in any way.
(morning temperature = basal body temperature)
• If you have past menstruation data, please enter it before the first temperature
reading.
• The alarm clock must be set on the previous day before 12 p.m. and must be
activated for the first day of application.
• Please stop taking the pill before using pearly.
Because: The programme is based on the fact that the ovulation is accurately
identified. The pill, however, prevents the ovulation.
• The coil which is doped with hormones must be removed before beginning.
In case of a copper coil it is recommended to remove it.
Right from the beginning the programme works with entered historical data.
The more regularly you take your temperature, the faster the device learns
to know your individual cycle.
It shows more and more green days (infertile days) and the red days (fertile
days) are more and more limited.
