Belifu 4-Channel TENS EMS Unit Instruction Manual

1. Introduction

The Belifu TENS EMS Unit is designed to provide pain management and muscle relaxation through Transcutaneous Electrical Nerve Stimulation (TENS) and Electrical Muscle Stimulation (EMS) technology. This device utilizes human body simulation technology, bioelectricity technology, and microcomputer intelligent control to simulate various massage methods such as cupping and acupuncture. It is intended for temporary relief of pain associated with sore and aching muscles in the shoulder, waist, back, neck, upper extremities (arm), and lower extremities (leg) due to strain from exercise or normal household and work activities. It is also intended for symptomatic relief of chronic, intractable pain and post-traumatic or post-surgical acute pain.

This unit features 4 independent channels, allowing for separate mode and intensity settings for each channel, and offers 24 pre-programmed massage modes with 30 intensity levels. Its compact, rechargeable design makes it convenient for use at home, in the office, or while traveling.
