SOLUTION
Check the power cord. Be sure it is plugged into both the wall
outlet and into the side of the pump housing. Check that outlet has
power by plugging in a device that you know is working.
If the power unit is on AUTO FIRM you will not be able to adjust
the comfort level until you turn off AUTO FIRM, by pressing the
Therapy Button.
The AUTO FIRM mode is intended for temporary situations. This
mode is only active for 30 minutes. Then the pump returns to the
previous setting.
