Battery types
The detectors are intended to be used with 1 x CR 2 lithium batteries (3 V). The use of
rechargeable batteries is not recommended, since the voltage level of rechargeable batteries is
lower than that of lithium batteries.
Their use would mean that the "Battery low" warning is mistakenly displayed and could also
lead to the limitation of functions during the software update of the devices.
