Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the Pacifier Activated Lullaby (P.A.L) Model #PAL-HOS is used exceeds the
applicable RF compliance level above, the Model should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the Pacifier Activated Lullaby (P.A.L) Model
# PAL-HOS. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m

The Pacifier Activated Lullaby (P.A.L) Model PAL-HOS is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The user of the Pacifier Activated Lullaby (P.A.L) Model # PAL-HOS can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the
Pacifier Activated Lullaby (P.A.L) Model # PAL-HOS 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
determined 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.
