1.  Operating the power supply with the adapter: Insert the output 
and input plugs of the adapter (switching power supply) into the 
port at the lower part of the massager and the AC power socket.
2.  Operating the power supply with the built-in rechargeable battery: 
The built-in rechargeable battery enables you to use the device 
without cords. Simply charge the device using the included 
adapter to use wire-free. 
HOW TO OPERATE THE 3-IN-1 HEATED NECK 
1.  Shift the toggle switch to the “ON” position and then apply the 
massager close to your neck. If there is some sweat on your neck, 
wipe it off before using the device.
2.  Hold the remote control and press the button “    ” to turn it on. 
After you hear the buzzer beep once, the power supply indicator 
will be on and the default program is enabled. The massager will 
work under Impulse Mode 1, Intensity 01 and Level H of thermal 
moxibustion, with a default time period of 15 minutes.
Optional: Use the remote control to adjust the massage mode and 
intensity to your liking. When using the remote, you must aim it at the 
massager’s receiving window. After the massager receives the infrared 
ray signal successfully it will beep once for prompting.
3.  There are six modes of intensity under the impulse mode “   ” for 
selection. Mode 0 refers to stopping massage. The “+” button is to 
increase the intensity by one level each time you press the button. 
Press the “-” button to decrease the intensity. There are 16 levels 
for adjustment. The default level is Level 1 when booting.
4.  The button “   ” is for selecting thermal moxibustion mode. And 
the “0” refers to stopping thermal moxibustion mode. Note: “L” 
means low temperature and “H” high temperature. It defaults to 
5.  The button “    ” is for selecting vibration mode, with six sub-
modes of 1~6. “0” refers to stopping the vibration. Press the “+” 
button once to increase the intensity by one level each time you 
press the button. There are three levels for adjustment.
6.  After the massage is completed, shift the toggle switch to “OFF” 
to power the massager off. Stick the electrode slices on the 
storage board for storage in a dry, well-ventilated place for next 
7.  When the battery runs low, please charge it with the power 
adapter provided with the massager. Otherwise, the massager will 
automatically turn off after the indicator flickers.
8.  When the remote control backlight flickers or becomes 
insensitive, it is recommended to replace the button battery (Use 
3V, CR2032 batteries only). The normal battery life is more than 
Attention: When you use the remote control to operate the massager, 
the IR receiving window on the massager and the IR sending window 
on the remote control cannot be shielded. Aim the remote control at 
the receiving window as much as possible to get the best sensitivity.
USE OF SILICON ELECTRODE SLICES
•  Insert one end of the 2-core connector wires into the electrode 
port and connect the other end to the electrode slices, then use 
the massager as specified above. If they are used together with 
the conductive plates there will be a difference in intensity due to 
the parts they are applied to.
•  The electrode slices should be clean on their surfaces without 
any dust, oily or sticky substances. If their surfaces become dirty, 
flush with clean water and then air dry them for repeated use.
•  The electrode slices can be used about 80 times (20 minutes 
each time). If their viscosity still cannot be recovered after 
several times of cleaning, consider purchasing new ones.
•  Only the electrode slices provided with the massager should be 
used. Each electrode slice is 2.2” wide, 3.1” high and 0.09” thick
•  Please dispose of electrode slices according to your local 
environmental regulations rather than discarding them at will.
Note: It is recommended to use the massager one to two times a day, 
10 to 20 minutes per massage, and 15-30 minutes in electric impulse 
•  When the buzzer beeps continuously during a massage, the built-
in lithium battery is low and needs charging with the adapter. 
Shift the toggle switch to “Charge” position. The power indicator 
will turn green and flicker. When it is fully charged, the power 
indicator will stay green. Charge time is 3 to 4 hours. 
•  The battery can be used for about one week (30 minutes a day) 
•  Under normal use, the rechargeable battery supports 500 
charges. When it is not in use for a long time, please charge it 
once a month to prevent reducing its service life.
