1. Hand Controller Functions:
Button No. Function
1 When in audio rhythm mode (short press button 7 to open audio rhythm
mode) or when vibrators are in fixed/pattern vibration, short press button 1 to
only control the light strip on/off; When not in audio rhythm mode and vibrators
are not vibrating, each short press of button 1 cycles the light strip color
(White, Red, Orange, Yellow, Green, Blue, Purple, Off, White, Red...)
2 Long press button for 3s, backlight flashes 2 times, child lock activated; other
buttons pressed will cause backlight to flash 3 times; Long press button again
for 3s, backlight flashes 3 times, child lock released, other button functions
restored
3 Short press button, actuator runs to zero-gravity position and stops
4 Short press button, actuator runs to anti-snore position and stops
5 Short press button to enable audio rhythm mode (vibrators and light strip are
both in audio rhythm mode); during music playback, light strip and vibrators
will change with the rhythm; Short press button to exit audio rhythm mode
6 Short press button, actuator runs to M1 position and stops; Long press 3s to
set memory M1 position (previous position is overwritten, control box receiver
buzzer beeps 1 time); after memory position is set, short press to run actuator
to M1 position
7 Waist actuator retracts, press to execute, release to stop
8 Leg actuator extends, press to execute, release to stop
9 Head actuator extends, press to execute, release to stop
10 Head and leg actuators retract to bottom, waist actuator extends to top, short
press to execute
11 Head actuator retracts, press to execute, release to stop
12 Leg actuator retracts, press to execute, release to stop
13 Waist actuator extends, press to execute, release to stop
14 Each short press of button switches head and leg vibrator vibration modes (1-
2-3-4-1-2-3-4... cycling in sequence)
15 Foot vibration motor intensity enhancement (total 10 levels), each press
gradually increases intensity
16 Head vibration motor intensity enhancement (total 10 levels), each press
gradually increases intensity
17 Short press button, head and leg vibration motors stop working
18 Foot vibration motor intensity reduction (total 10 levels), each press gradually
decreases intensity until off
19 Head vibration motor intensity reduction (total 10 levels), each press gradually
decreases intensity until off
Notes:
① After hand controller button 5 enables audio rhythm, buttons 14, 15, 16, 17, 18, 19 are invalid;
② Synchronization function: AUX input (IN) must be connected to another control box's output
(OUT) interface. It is prohibited to connect two control boxes directly with AUX input (IN) to AUX
input (IN), or AUX output (OUT) to AUX output (OUT); incorrect connection will only affect
functionality and will not damage the control box; the control box connected to AUX output (OUT)
is the master (Bluetooth open machine), and the one connected to AUX input (IN) is the slave;
after AUX input (IN) is connected to another control box's AUX output (OUT), it can only be used
as a slave, and Bluetooth cannot be searched or connected;
③ Search for Bluetooth name REV-HARMONIQ to pair and connect; after system power-off, the
Bluetooth status will be refreshed and re-searching and pairing connection is required.

2. Precautions:
① Before use, please be sure to connect wires correctly according to the system connection
diagram, then turn on the main power;
② Children, elderly and disabled persons should use under supervision;
③ Do not plug or unplug any connecting cables when the power is on, as this may cause
operational malfunction; if this occurs, cut off the main power and reconnect after approximately
30s;
④ Before first use, the wireless hand controller should be paired with the KD control box as
follows:
a. Press and hold the pairing button on the KD control box for 3S, the indicator light will be in
fast flashing state, release the button;
b. Within 15s, press button 8 + button 9 on the hand controller, the control box indicator light
stops flashing, buzzer sounds 1 time, indicating successful pairing, control box indicator light
stays on;
c. After successful pairing, operate the buttons and corresponding functions will begin to
execute;
⑤ The method to unpair is as follows:
a. Press and hold the pairing button on the KD control box for 3S, the indicator light will be in
fast flashing state, release the button;
b. Within 15s, press button 11 + button 12 on the hand controller, the control box indicator light
stops flashing, buzzer sounds 1 time, indicating successful pairing removal, control box indicator
light stays on;
c. After successful pairing removal, operate the buttons and corresponding functions will be
invalid;
⑥ The KD control box can be paired with two hand controllers; if paired with a third, the first one
will be cleared.
⑦ It is not recommended to operate multiple actuators simultaneously, except for special
functions;
⑧ Please replace the hand controller battery in time; when not in use for a long time, remove the
battery.
