If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Philips Avent breast pump.
Over the frequency range 150 kHz to 80 MHz, eld strengths should be less
than [3] V/m.
Recommended separation distances between portable and mobile
RF communications equipment and the Philips Avent breast pump
The Philips Avent breast pump is intended for use in a home healthcare
environment in which radiated RF disturbances are not controlled
The user of the Philips Avent breast pump can help prevent electromagnetic
interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the Philips Avent
breast pump as recommended below, according to the maximum output
power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in metres (m) can be estimated using
the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to
the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
Note 2:These guidelines may not apply in all situations. Electromagnetic
propagation is aected by absorption and reection from structures, objects
and people.
Usage and storage conditions
Keep the breast pump out of direct sunlight as prolonged exposure may
cause discoloration. Store the breast pump and its accessories in a safe,
clean and dry place.
If the appliance has been stored in a hot or cold environment, place it in the
usage environment to let it reach a temperature within the usage conditions
( 41°F / 5°C to 104°F / 40°C ) before you use it.
