1. When the power is turned on, the power indicator light is on. Press the switch, and the main engine will fully pressurize the air cushion.
2. The inflation intensity change-over switch is "strong" clockwise and "weak" counterclockwise.
3. The air cushion inflation conduits are connected, and the inflation pressure of the main air pump alternately inflates and deflates the air bag through the two conduits.
How to use:
1. Place the air cushion flat on the bed with the surface covered by a sheet, and connect the two inflatable conduits on the air cushion to the inflatable conduit nozzle of the main engine respectively.
2. Turn on the power supply, turn on the power switch, and the host starts to work.
3. When it is used for the first time, turn the inflation intensity change-over switch clockwise to the "strong" position.
4. At night or when the patient feels that the air pressure changes dramatically, turn the change-over switch counterclockwise to a weakly inflated state.
