RF emissions CISPR 11
Group 1
RF energy is used only to maintain device’s operation.
Therefore, its RF emissions are so low that it’s not likely to
cause any interference in nearby electronic equipment.
RF emissions CISPR 11

environment. If the user of the de-
vice requires continued operation
during power mains interruptions,
it is recommended that the device
be powered from an uninterruptible
power supply or a battery.
