unknown.
n Apply stimulation to only normal, intact, clean,
dry, and healthy skin.
n TENS is not effective in treating the original
source or cause of the pain, including headache.
n TENS is not a substitute for pain medications
and other pain management therapies.
n TENS devices do not cure disease or injuries.
n TENS is a symptomatic treatment and, as such,
suppresses the sensation of pain that would
otherwise serve as a protective mechanism.
n Effectiveness is highly dependent upon patient
selection by a practitioner qualified in the
management of pain patients.
n You may experience skin irritation or
hypersensitivity due to the electrical stimulation
or electrical conductive medium (gel) on the
electrodes.
n If you have suspected or diagnosed heart
disease, you should follow precautions
recommended by your physician.

What is it?
The Dual Channel TENS ACRL-3000 is a two
output channel TENS machine and is highly
effective in relieving pain. TENS is now regularly
recommended by doctors, physiotherapists and
pharmacists throughout the world.
Transcutaneous Electrical Nerve Stimulation (TENS)
is a noninvasive, drug-free method of controlling
pain. TENS uses tiny electrical impulses sent
through the skin to the nerves to modify pain
perception. TENS does not cure any physiological
problem. It only helps control the pain. TENS does
not work for everyone. However, in most patients,
it is effective in reducing or eliminating the pain,
allowing for a return to normal activity.
HOW TENS WORKS FOR PAIN RELIEF
How TENS works?
Scientific theory suggests that electrical stimulation
therapy may work in several ways:
n The gentle electrical pulses move through the
skin to nearby nerves to block the pain message
from the source of pain from ever reaching
the brain.
n The gentle electrical pulses increase the
production of endorphins, the body’s natural
pain killer.

14
KNOW YOUR DEVICE
Features
n Two output channels TENS stimulator, allowing for the option of two or four electrodes. The lead wires
insert into Channel 1 and Channel 2 and each wire connects to two electrodes. The intensity of each pair
of electrodes can be adjusted independently, and it is not necessary to have both channels running (you
can use just one wire with two electrodes).
n ACRL-3000 offer six (6) programs (P1~P6) for you to choose from plus an additional six (6) PE preset
programs that are suitable for different parts of the body and pain.
n 25 intensity levels of therapy, one (1) low intensity to 25 high intensity.
