The quality of the supply voltage should
correspond to that of a typical store or clinic
environment. If the users of the device require
continuous operation, even in case of power
outages, it is recommended to feed power to
the device via an uninterruptible power
supply or a battery.
Radiated fields in close proximity in
accordance with IEC 61000-4-39
8 A/m at 30kHz
65 A/m at 134.2kHz 7.5 A/m at 13.56kHz

Avoid exposure to known sources of EMI
(electromagnetic interference) such as
diathermy, lithotripsy, electrocautery, RFID
(Radio Frequency Identification), and electro-
magnetic security systems such as anti-theft/
electronic article surveillance systems, metal
detectors. Note that the presence of RFID
devices may not be obvious. If such interfe-
rence is suspected, reposition the equipment
if possible, to maximize distances
