Electromagnetic environment - guidelines
custo watch uses the frequency band in the range 2.4
GHz for communication with the custo guard ECG trans-
mitter. RF emissions are very low and it is unlikely that
adjacent electronic devices will be disturbed.
custo watch is designed for use in all establishments, in-
cluding domestic establishments and those directly con-
nected to the public low voltage power supply network
that supplies buildings used for domestic purposes.
