Foreword
Precautions during repairs and faults:
a. When disassembling, unplugging connectors and replacing parts, make
sure to unplug or turn off the power.
b. As semiconductors (IC, etc.) are prone to being damaged by static
electricity, please use human body electrostatic discharge ground wire if it
is required to directly contact the baseplate when performing operations, or
touch the ground wire (ground wires of fridges, washing machines, etc.)
with bare hands to discharge the static electricity of the human body before
carrying out operations.
c. The circuit baseplate mixes high voltage (AC110V, AC220V) and low
voltage (12V, 5V), which may cause electric shock accident; so please do
not have direct contact without preparations.

previous layer of menu; this key has the same function as the
ESC key of the computer keyboard
ˋʳˁʳAfter element selection, use AIR STRENGTH to adjust the
element speed, and the intensity will be displayed as the air
pressure strength, with one to three representing from weak to
strong

P1 Motor testing mode
A0 : Up and down movement of machine core
A5 : Machine core pounding motion
A4 : Kneading-Forward and reverse rotation of machine core
A3 : Front and back movement of machine core
A2 : Up and down movement of chair back
A1 : Up and down movement of foot machine
Motor test mode is mainly used to test if each motor works normally and to adjust
chair angle when replacing elements
2-1. Engineering mode: P1

Johnson Health Tech. Co., Ltd.
P2 sensor testing
C0 : Up and down movement of machine core
C4 : Kneading-Forward and reverse rotation of machine core
C3 : Front and back movement of machine core
C2 : Up and down movement of chair back
C1 : Up and down movement of foot machine
Sensor testing is mainly used to test and indicate limits and counts. When
operating motor in this mode, LCD time window will display the digit returned by the
sensor. When the digit exceeds 100, the carrying digit will display “massage intensity”
(100~500) and “motion menu”.
LCD sensing position display window will indicate whether the limit switch is
triggered

motion
The left figure shows that the upper limit
is reached when the selected machine core
(C1) rises
When the upper limit light is, it means that
the machine core is unable to move upward;
when the lower limit light is on, the machine
core is unable to move downward
The “Massage Strength” lamp signal 1 of
massage intensity represents 100, 2 represents
200, and so on
“KNEAD” lamp represents 600,”KAT” lamp
represents 700.
We can tell by the above rules that the returned
value on the left figure is time window (40) +
motion menu lamp signal (700) =740

P3 current testing
D0 : Up and down migration current of machine core
D4 : Kneading-Forward and reverse rotation current of
machine core
D3 : Front and back migration current of machine core
D2 : Up and down migration current of chair back
Current testing is mainly used to test if the motor current is too high
When the returned number exceeds 100, the carrying digit will display “massage intensity”
(100~500)
D3 is a major test item; if the intensity is set to medium (air bag strength 2) and machine
core forward value is greater than 50, it is likely to generate error code D0 because the
current is too high to lower the sensitivity of induction mechanism
2-3. Engineering mode: P3

Air bag testing is mainly used to test if the air bag
works normally, the inflation rate is normal, there
is leakage, etc.
It can also distinguish the position of the air bag to
be tested via the pattern on the manual controller.
P4 air bag testing
1: left arm air bag
2: right arm air bag
3: air bag above the leg
4: instep air bag below the
leg

Software version check mode is generally used to confirm current version of massage chair and
confirm again if the update is successful after updating software
a. Press “up” or “down” key to make the time window display “PU” to enter software version check
function
