Guidance and Manufacture’s Declaration for recommended separation distances between portable and mobile RF communications equipment and the VALO
The VALO is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The user of the VALO can help prevent electromagnetic interfer-
ence by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the VALO as recommended below, according to the
maximum output power of the communications equipment.

The VALO has been tested according to IEC 60601-1-2:2014 and passed under radiated field strengths of 10 V/m between 80-MHz to 2.5 GHz. The value of 3Vrms corresponds to
V1 and the value 10 V/m corresponds to E1 in the formulas above.
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.
