Water Jet Neck Pillow
- Neck Masseuse
The neck is the body's most vital passageway. Circulation through this small region is key to relieving muscle tightening. Muscle tightening is the result of accumulated stress and poor circulation. Each negative aspect works on the other to create discomfort. The Neck Masseuse is designed to increase circulation and relax muscle tension. The Neck Masseuse sends hydro massaging water onto the neck.
You select the pulse level. Level one is subtle and sleepy. Level two is attention getting and soothing. Level three is intense for maximum stress relief.
Operation:
The optional neck masseuse pillow jets can be turned on any time the whirlpool pump is running. Press the pillow key once to turn on the pillow jets. Press the key again to turn them off. To adjust the speed of the pulsating jets, press the pillow key and hold it down until the red"mode" light comes on. With the light on, you can adjust the pulse to any of three speeds. Press the minus key to slow the pulsing, press the plus key to increase it. The red mode light will remain on while you are adjusting the speed, and will turn off automatically fifteen seconds after you've finished.
