The CEFAR BASIC has two channels, so you can ease pain in two places at once. The channels use the same stimulation program.  The CEFAR BASIC has an automatic keypad lock, which prevents the amplitude from being changed accidentally. This means that you can use the CEFAR BASIC during activity, wherever you are, without having to worry about the amplitude changing. The CEFAR BASIC has a spacious screen surface with a back-light feature. This makes the screen easy to see and read. Other features include a pause function, a program lock, a key lock, compliance, and self check.

The CEFAR BASIC has three preset programs. 

Program 1, Conventional TENS

High-frequency stimulation is the first choice for both acute and chronic pain. It blocks the pain so that it feels much milder, or cannot be felt at all. Program 1 can be used for: neck pain, back pain, shoulder pain, elbow pain, rheumatic pain, menstrual cramps, phantom pain, hip pain, osteoarthritis of the knee and to help heal wounds

Program 2, Burst TENS

Low-frequency TENS treatment can alleviate pain by stimulating muscles to release the body has own morphine-like substances, endorphins. Place the electrodes on a muscle in the painful area so that a visible contraction occurs. Low-frequency stimulation is usually most effective for pains that radiate out into the arms and legs (projecting pain), deep muscle pain or when the effects of high-frequency TENS do not last long enough.

Program 3, Modulated pulse duration stimulation

Modulated pulse duration stimulation is a type of high-frequency stimulation. The length of each pulse varies continuously, giving an undulating sensation, which many people find very pleasant. Program 3 can be used for the same symptoms as program 1, or if you want to ease pain and massage the muscles, for example in the neck.
