If continued
operation during power mains interruptions beyond that provided by the battery,
it is recommended that the device be powered from an uninterruptible power
supply.
Power frequency magnetic fields should be at levels characteristic of a typical
location in a typical home environment. Power frequency magnetic fields from
appliances in the home are not e
