Operating the device
Operating the device
• Unlock the battery cover by turn-
ing it past the marker to the left.
Then lift the cover off.
• Remove the old battery and insert
a new battery (CR2032) with the
“+” symbol facing up.
• Place the cover back on the bat-
tery compartment and lock it in place.
Battery display/changing the battery
The device is equipped with a CR2032 lithium battery.
If the battery icon flashes on the display while
the thermometer is in use, the battery is low
(Figure 1). You can still perform some tempera-
ture measurements at this point, but you should
have a spare battery ready.
After changing the battery, the thermometer must be connected to
the mySense app so that the date and time can be resynchronised.
Until you have done this, you cannot take any new temperature meas-
urements.
Change the battery if:
– After switching on the device, the “battery
flat” indicator (Figure 2) appears on the dis-
play. You must insert a new battery before
you can take any temperature measure-
ments
– Nothing is shown on the display despite
pressing the on/off button.

Measurement values stored on the device are retained when the bat-
tery is changed.
Changing devices
Each mySense basal body temperature thermometer has a unique
signature assigned to a specific user. Signatures are assigned during
initial setup when the device is synchronised with the mySense app
for the first time.
If your device is lost or faulty, you can assign a new mySense basal
body temperature thermometer to your user account.
To do this, follow the instructions in the chapter “Initial setup” on page 7.
Please note: If you change device during a cycle, the current cycle be-
comes inactive in the mySense app. For your safety, the mySense app
only accepts measurement data from a single device during a cycle.
