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).
To reset the service mode, turn OFF the POWER switch.
<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).
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.

Air-Bag Operation Confirmation Procedure
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.
Start-up of Examination Mode
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.

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

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 Istop 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.
