Replacing batteries
We recommend that the set of batteries in the device should be replaced
by a freshly charged set once a 24-hour reading has been completed.
In order to prevent data loss, the data stored in the boso TM-2450
are buffered via an internal battery. This internal battery is charged
automatically via the external batteries. A fully-charged internal battery
stores data for approximately 10 days. To charge the internal battery
fully before using the device for the first time, keep the device switched
on for approximately 24 hours with fully charged external batteries.
Replace the batteries as follows
(see figure 2):
Open the internal battery compartment cover (step 1)
Remove the flat rechargeable batteries (step 2) and insert the
charged rechargeable batteries (step 3), taking care to respect
polarity (step 4)
Close the internal battery compartment cover (step 5)
