Using the Jade Heat System
Press the heat button to toggle through low, medium, high, and off. The Jade Stones radiate far-infrared
rays that deliver warmth into muscle tissue. Once the deep penetrating heat reaches the optimal
temperature, the desired level of warmth is maintained.
NOTE: The Jade Heat system automatically powers off after two hours of no use.
Using the adjustable lumbar system
Press and hold the plus button to inflate the lumbar area; press and hold the minus button to deflate it.
The adjustable lumbar system requires four AA alkaline batteries (see page 14 for installation instructions).
Battery life depends on usage, however with average use you should expect to change the batteries
approximately once a year.
