recommended separation distances
Recommended separation distances between portable and mobile RF communications equipment and
the Gait trainer 3 treadmill. table 6
The Gait Trainer 3 Treadmill is intended for use in the electromagnetic environment in which radiat-
ed RF disturbance are controlled. The customer or the user of the Gait Trainer 3 Treadmill can help
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communication equipment (transmitters) and the Gait Trainer 3 Treadmill as recommend-
ed below, ac¬cording 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 trans-
mitter, 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).
