Recommended separation distance between portable
and mobile RF communications equipment and the
Medela Apgar Timer
The Medela Apgar Timer are intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the Medela Apgar Timer can help pre-
vent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the Medela Apgar Timer 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 meters (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 affected by
absorption and reflection from structures, objects and people.
