1. FOREWORD
Introduction
The device R-C1 is a dual channel output TENS, EMS and
MASSAGE stimulator.Before using, please read all the in-
structions in this user manual carefully and keep it safe for
future use.
The COMBO stimulator belongs to the group of electrical
stimulation systems. It has three basic functions – TENS
(Transcutaneous Electrical Nerve Stimulation) , EMS (Elec-
tronic Muscle Stimulation) and MASSAGE.
Function of the COMBO stimulator: The device has 36
programs (18 TENS programs, 15 EMS programs and 3
MASSAGE programs) and applies electric currents in the
low-frequency range for therapy. Each program controls
the generated electric impulses, their intensity, frequency
and pulse width. The parameters for each program are list-
ed in clause 7.1.
Based on simulating the body’s natural pulses, the mech-
anism of electrical stimulation equipment is to create
electric impulses that are transcutaneous transmitted to
nerves or muscle fibers through electrode . The intensity of
the dual channel can be adjusted independently and can
be applied individually to one body part. This dual channel
device can be used with four pieces of electrodes, which
allows you to stimulate one muscle groups simultaneously
with a wide selection of standard programs. The electrical
pulse is firstly transmitted to the tissue, then it affects the
transmission of stimulation in nerves as well as muscle tis-
sues in the body parts.
