Guidance and Manufacturer's Declaration — Electromagnetic Immunity
The recliner is intended for use in the electromagnetic environments specified below.
The customer or the user of the recliner must use it in an environment specified here.

level in each frequency range.
Interference may occur in the vicinity

a. Field strengths from fixed transmitters, such as those of base stations for radio (cellular/cordless) telephones, land mobile
radios, amateur radios, AM and FM radio broadcasts, and TV broadcasts cannot be predicted theoretically with accuracy.
To determine the electromagnetic environment due to fixed RF transmitters, an electromagnetic survey of the site should be
considered. If the measured field strength in the location in which the recliner is used exceeds the applicable RF compliance
level above, the recliner should be observed to verify whether or not it is operating appropriately. If an abnormal operation is
seen, take additional measures as needed, such as changing the location of use of the recliner.
b. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects, and people.
