We would like to congratulate you on your decision to have a natural
contraception in future.
With pearly you have a very reasonable and healthy and environmentally
friendly alternative to conventional contraception methods along with the
optimal safety on “green days”.
Please read these instructions attentively and completely for your own
safety. Everything you should know about the device can be found in the
Table of Contents or in the Alphabetic Index.
We wish you a good start.
Congratulations

• 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.

When putting into operation sample values
are saved in your pearly. These values are
automatically deleted as soon as you have
made your own first temperature reading.
The sample values appear again if you
ever delete your user data.
Temperature reading time limit
pearly controls the temperature reading
time limit. It comprises 6 hours, beginning
and ending three hours before and after
the temperature reading time, if differing
from the alarm setting time.
Temperature can only be taken once a day,
within the temperature reading time limit.
You recognise the temperature reading
time limit by the constantly illuminated
temperature reading symbol.
Taking your temperature, general information
Taking your basal body temperature re-
liably every day is one of the key elements
of our system. The basal body temperature
is the temperature immediately after
waking up, before getting up, before be-
coming active in any way.
The more regularly you take your tempera-
ture, particularly at the beginning of the
application, the faster the device gets to
know your personal cycle.
Information on taking your temperature
Place the thermometer under your tongue,
right at the back, either to the left or the
right of the frenulum and close your mouth.
While taking your temperature, the thermo-
meter should not be moved. You will get the
best results when choosing the same ther-
mometer position every day.

................................................................
Temperature reading
pearly wakes you up with a signal
tone. By pressing any button, the
alarm tone can be switched off.
If you want to take your tempera-
ture, press a button subsequently
again.
The symbol “temperature reading”
flashes, pearly is ready for a tem-
perature reading.
• Now place the thermometer under your
tongue and close your mouth.
• The temperature reading takes approx.
50 - 60 seconds.
• Should there be interruptions when taking
your temperature, e.g. by moving the
thermometer in your mouth, the tempera-
ture reading is automatically extended.
• You can hear an acoustic signal when
the temperature reading is completed.
Temperature reading 15

...............................................................
Enter menstruation data “M”
16
Enter menstruation data “M”
After the temperature reading the
“M” = menstruation symbol
possibly flashes.
• If you are menstruating, press the plus
button and if you are not menstruating,
press the minus button.
• In the further cycle course pearly asks
only for menstruation if it is expected.
• The “M” query begins two days before
the menstruation is to be expected, so
you can adapt yourself.
• Should you menstruate later than
expected, negate the question regar-
ding “M” by pressing the minus button.
“?” appears if no plausible data
is entered. Please repeat input
correctly.
Activating “M”
If you menstruate earlier than expected
and pearly does not ask for “M”, you have
the possibility to activate “M” yourself.
Proceeding from the window “temperature
reading value”:
• If you press and hold the round button
for 5 seconds, “M” flashes.
• Confirm “M” for this day by pressing the
plus button.
• As confirmation “M” remains illuminated.
Entering “M” at a later time
If you have not entered “M” after an inter-
ruption of use (e.g. because you were ill or
on holiday) and you would like to supple-
ment the data, this is possible within the
first three days of back in operation
(see Activating “M” and Entering past men-
struation data page 12).

................................................................
Travelling/Time zones
When travelling in different time zones you
have the possibility to change the date and
time to the local time. The temperature
reading does not apply on the first day.
Shift work
In case of shift work the alarm setting and
therefore the temperature reading time limit
is directed towards the real sleep time.
Basically the basal body temperature
(wake up temperature) must be recorded.
Pregnancy display
pearly indicates a pregnancy starting from
the 18th day following fertilisation by the
simultaneous constant illumination of the
red, yellow and green indicators.
Mono-phases
If there is no ovulation in a cycle, pearly
indicates this with •red•.
Back in operation after an interruption
The date, the year and the time continue to
work automatically unless the battery is flat.
The temperature reading time limit is left
open due to the fact that no temperature
readings were made and must be reset via
the alarm clock. Data remains to be stored,
even if the battery is run-down.
Cleaning the thermometer
The tip of the thermometer can be cleaned
with lukewarm water. Please do not use
chemical substances and no alcohol.

3 years. After expiry of this time we ask
you to send the device in to replace the
battery.
We save your data, replace the battery,
load the latest software, if any, and send
the device back to you. Then pearly oper-
ates again for a period of 2 to 3 years.
If the complete state of charge of the

BA:01 the battery is run-down
(Delete display:
press plus and minus button
simultaneously)
Print-out
The last 99 days of your cycle data stored
in your pearly can be printed out at your
producer and can be analysed afterwards.
Deleting saved data
User data can be completely deleted and
the device can be set into an initial state.
• Press the plus button for 5 seconds,
then the test run will start.
• During the test run press all 3 buttons
simultaneously for 5 seconds.
• L-:09 appears.
• You must count down by pressing the
minus button until the display shows
L-:00.
Your data is now completely deleted. You
will hear an acoustic signal. The sample
values are shown on the display again, as
it is the case at the beginning of the appli-
cation.
