aField 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 Stretchair is used exceeds the applicable RF compliance level above, the
Stretchair should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the Stretchair.
bOver the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

GENERAL CARE & CLEANING OF VINYL UPHOLSTERY
Remove hair & body oils; Your recliner should be cleaned with mild soap & water solution and a
damp cloth on a regular basis (especially where skin & hair make contact with upholstery). Avoid
harsh detergents or chemicals that could damage the upholstery or finish of your recliner. If the
recliner is disenfected, the chair MUST be wiped off with ONLY clean water on a damp cloth.
Note: Disinfectants alone, will not provide adequate "grease or oil cutting" properties to remove hair
& skin oils. Over time, the appearance and feel of your upholstery may diminish if not cleaned
properly.
Please refer to the PERMABLOK instruction tag that is attached to your Care Cliner for complete
care and cleaning instructions.
Retain information on tag for future use.
