Does iReliev Electrode Pads Made with Gel Contain Salicylate?

iReliev gel pads do not contain salicylate which is necessary for many people seeking to follow protocol consistent with Guaifenesin protocol.  Considered by many as an unapproved treatment for fibromyalgia suggested in the 1990s by R. Paul St. Amand. The protocol involves three parts: titrating the guaifenesin dosage, avoiding salicylates, and following a low-carbohydrate diet if the patient is hypoglycemic.

How many electrode pads come with model ET-1313?

A quantity of 4, 2″ x 2″ electrode pads come with the system.

Why won't the intensity increase?

Please make sure that the following steps are completed:

Step #1) Make sure lead(s) is fully inserted in respective CH1 or CH2 port on device.

Step #2) Make sure electrode pads are fully inserted into pin connectors on lead wire(s) .

Step #3) Make sure 2 or 4 electrodes ( 2 small or 1 XL pad per channel) are placed on the body. System can only function if conductive resistance is sensed by machine (all steps above) otherwise auto default to intensity level “0” is initiated. It's a safety feature.

We would love to help. Or message back with specific problem and we will assist further. Also we have a great set up video. See top Video on page Click Link Here:

Where is the serial number?

The serial number is on the bottom of the unit.

Can unit be used without the timer?

No, the TENS unit only works with the timer. The minimum time is 5 minutes and the maximum time is 60 minutes. You will have to re-set every 60 minutes for continuous usage.

Do you ship internationally?

Yes, we ship internationally.

Can I use iReliev if I have a pacemaker?

No. iReliev should not be used if you have a pacemaker, defibrillator, or any implanted electronic device. Also, iReliev should not be used if you have any implanted medical devices containing metal.

Can I adjust the intensity?

Yes, since pain is subjective, all iReliev devices provide adjustable intensity allowing you to customize your therapy as to whatever feels comfortable for you.

Can this model be used with iReliev's conductive back wrap accessory?

Yes, it can.

will the machine run continuously?

It has a timer that can run for up to 60 minutes continuously. Then it shuts off. You are able to restart the unit right away.

Can I use iReliev in conjunction with topical pain rubs or gels?

Topical pain creams, rubs or gels can be used before or after the use of iReliev TENS and/or EMS. Please note, topical pain creams should not be applied to the site of pain immediately before applying the iReliev electrode pads. Applying topical pain rubs in combination with the iReliev electrode pads may damage the electrode pads and prevent you from experiencing optimal electrotherapy results. However, many of our customers use gel for optimal electrical dispersion. It can increase conductivity, creating a more comfortable experience while hydrating the moisture of the gel on the original pads.

How does iReliev TENS help reduce pain?

iReliev works by producing electrical pulses that block the body’s pain signal to your brain, thus the pain symptoms you feel. TENS has also been shown in clinical studies to encourage the body to release its own natural pain relieving endorphins, sometimes referred to as the body's “feel good chemical.”

Can I use iReliev while pregnant?

Do not use during pregnancy or if you think you might be pregnant.

Do iReliev products require a Doctor’s prescription (RX)?

Nope. All iReliev devices are FDA cleared over-the-counter (OTC) devices. This includes our latest PlayMakar ET-5050 system, a high output, wireless system.

How long can iReliev TENS and/or EMS be used in a day?

Therapy sessions can last 60 minutes or less. You can use iReliev for consecutive 60-minute sessions according to your pain relief needs when used in accordance with the user manual.

Many of our customers ask…can I use rechargeable batteries with ET-1313 or ET-7070 Dual Channel TENS or TENS + EMS Units?

Standard AAA batteries can provide over 30 hours of TENS or EMS treatment. However, if you would like to use rechargeable batteries you may do so but we don't recommend as they can vary in many different technical outputs that could affect the device itself. We do have customers however, who say that they use rechargeable batteries with no problems.

How do I lock and unlock the unit so that I can carry it in my pocket without changing the settings inadvertently?

To lock: Press ON/+ and OFF/- at the same time. To release, do the same thing.

What is the power output of this product?

80mA output or 25 levels of intensity. 80mA is equivalent to many portable prescription models. It is very strong I assure you.

does anyone know the difference between the 1313 model and the 7070 model?

Yes, the 1313 is just a tens unit for pain. The 7070 is a tens unit for pain and also ems for muscle strength and rejuvenation.

Is it necessary to use electrode gel with this device?

No, it is not required as the electrodes are pre-gelled.

Is this for 110 volts and 220 volts?

It's a battery operated unit which uses 3×1.5V batteries – 4.5V total

The user manual says to make all connections before applying the pads. Can the pads be applied, make the connections and then turn on the unit?

Yes, that works.

Is the control unit and keypad backlit for use in dim situations or at night?


Can the intensity selections be manually adjusted during the sessions, or do you have to reset it to get it just right?

Yes, you can change it during a session. Best way to adjust to a comfort level actually.

What kind of batteries does it use?

3 AAA batteries

Does it come with a belt clip?

Yes, it comes with a belt clip that the unit can sit in.

I have an issue adjusting the intensity past 1 or getting the unit to start once everything else is set up.

First, ensure your batteries are good. Then, Please ensure you have lead(s) fully seated into the device. Please ensure you have both lead wire pins fully inserted into 1 large or 2 small electrode pads. Please ensure pads are fully adhering to your body. You may call us for support. We will always respond.

I need this for plantar faschiitis of foot – are the pads small enough for the bottom of the foot arch?

Yes, iReliev's 2″ x 2″ pads are small enough for the arch of the foot.
