Error message indication (in Service Mode)
*Abnormal indications detected during operation are stored in a memory up to seven. Seven abnormal indications stored can be confirmed in the service mode (Older indications than the seven abnormal indications will be deleted sequentially).
To change over to the service mode, turn ON the POWER switch at the rear of the massager while simultaneously pressing the OPERATION ON/OFF on a remote controller. When the "FINE" button is pressed three times with the OPERATION ON/OFF kept pressed, the massager is placed in the service mode.
(When the massager is placed in the service mode, four blue lamps at the WHOLE BODY SENSOR AUTOMATIC COURSE come on).
POWER switch "ON" POSITION ADJUST "UP" "DOWN" button "FINE" button (three times)
To reset the service mode, turn OFF the POWER switch.
When the massager is placed in the service mode, the latest abnormal indication is displayed. The POSITION ADJUST "▼(DOWN)" button of the remote controller is used to display older abnormal indications one by one, and "▲(UP)" to display newer abnormal indication one by one (Following the sixth older (the oldest) indication, the latest indication is displayed again). Up to seven abnormal indications are stored in a memory. In case of less than seven, since there are not any abnormal indications, some of the seven STIFFNESS indicators are lit alternatively to indicate the state that abnormalities are not stored.
<Resetting Procedure of Abnormal Indication Memory>
Simultaneously press "REPATE" button on the sensor controller to delete all abnormal indication memory (When the seven STIFFNES indicators are all lit up, all abnormal indication memory have been deleted).

Air-Bag Operation Confirmation Procedure
Start-up of Examination Mode
Turn ON the POWER switch at the rear of the massager while simultaneously pressing the POSITION ADJUST "UP" and "DOWN" buttons and "SOLE WARMER" button on the remote controller (This operation should be started with the POWER switch turned OFF). When the examination mode is started up, both a backrest and a foot rest move slightly and come to a stop.
Air-Bag Operation Confirmation
Press either "▼(DOWN)" or "▲(UP)" button of the LOWER BODY adjustment on the remote controller.
Check if the air-bag inflates sequentially as shown below.
* If there are any problems, check air leakage, breakage of air hoses, and the air-bag.

When the examination mode is started up, both a backrest and a foot rest move slightly and come to a stop.
Air-Bag Operation Confirmation
Press either "V(DOWN)" or "A (UP)" button of the LOWER BODY adjustment on the remote controller. (move for 3min)
Motor Operation Confirmation
Seven motors work at the same time when they push "REPEAT" button.
Massage motor and tapping motor is fastest moves.
Elevevation motor and Strength motor goes to an upper
point and lower point and return.
Reclinning motor (foot rest/back rest/seat) repeats the expansion and contraction.
Movement / a stop is possible with a "REPEAT" button again and again.
*When I changed massage unit assembly / reclining motore /pcb, I confirm movement by this function.
Because lstop by an error when there is abnormality, I confirm a place of pertinence. As for this function , sole warmer / air pump / valve moves at the same time ,too.
