Table 12.5 Separation Distance Table
Recommended Separation Distances
Recommended separation distances between portable and mobile RF communications
equipment and the Gait trainer 3 are detailed in the following table.
The Gait Trainer 3 is intended for use in the electromagnetic environment in which radiated RF
disturbance are controlled. The customer or the user of the Gait Trainer 3 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communication equipment (transmitters) and the Gait Trainer 3 as recommended below,
according to the maximum output power of the communication 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.
Operating Temperature
Do not expose the equipment to a temperature change of more than 5° F (3° C) per hour. Limits
of low and high operating temperature ranges are 59° to 86° F (15° C to 30° C).
