Operating Instructions
Power On/Off:
Press and hold the On/Off button for 2 seconds to turn the device on or off.
Selecting a Therapy Mode:
Press the F (Function) button to cycle through the five available therapy modes: TENS, EMS, IF, RUSS, and DIY. The selected mode will be displayed on the screen.
This image illustrates the five core functions of the GHTENS KTR-2640 device. TENS is for pain relief, such as stiff shoulders and joint pain. EMS is for muscle relaxation and rehabilitation exercises. IF (Interferential Current) provides deep massage for discomfort. RUSS (Russian Stimulation) is used for muscle strength training and relieving muscle cramps. DIY allows for individual custom settings.
Selecting a Program:
After selecting a mode, use the Up/Down Arrow buttons to choose from the 80 integrated programs. The program number will be shown on the display.
Adjusting Intensity:
The device has two independent channels. Press the Ch button to select either Channel 1 or Channel 2. Once a channel is selected, use the +/- buttons to increase or decrease the intensity level. There are 16 intensity levels available.
This image illustrates the 16 intensity levels available on the device, ranging from soft (levels 1-3) to medium (levels 4-6), strong (levels 7-9), and high (levels 10-16). Users can adjust the intensity to their personal tolerance and comfort level.
Electrode Pad Placement:
Proper placement of electrode pads is crucial for effective therapy. Refer to the body diagram on the device's display or consult a healthcare professional for specific placement recommendations for your condition.
This image demonstrates the dual-channel capability of the device, showing how four electrode pads can be used simultaneously on different body parts. For example, Channel 1 is shown with pads on the arm at intensity level 2, while Channel 2 has pads on the calf at intensity level 4. This allows for simultaneous treatment of two areas or for two people to use the device at once.
Screen Lock Function:
Press the Lock button to lock the screen and prevent accidental changes to settings during therapy. Press it again to unlock.
