Portable TENS unit quick start
- 01
Charge the unit before first use.
- 02
With the unit switched off, connect the lead wires to the device and electrode pads.
- 03
Place pads on clean, dry and intact skin near the area being treated. Keep the pads separated.
- 04
Select TENS mode for sensory nerve stimulation or EMS mode for controlled muscle contractions.
- 05
Begin at the lowest intensity. Increase it slowly until the sensation is strong but comfortable, never painful.
- 06
Switch the unit off before moving or removing the pads.
Choose the right mode
TENS and EMS work differently
Sensory nerve stimulation
TENS usually produces tingling without a visible muscle contraction. It is commonly used as part of a pain-management plan.
Controlled muscle contractions
EMS produces visible muscle contractions. It is used for muscle activation or recovery under appropriate guidance.
Independent controls
Dual channel setup
Channels A and B have independent intensity controls. Connect one lead wire to each channel and adjust each side separately.
Do not position electrodes so electrical current passes across your chest.
Keep stimulation consistent
Electrode pad and lead wire care
Electrode pads
- Apply pads only to clean, dry skin without lotion or oil.
- Handle pads by the edge and avoid touching the gel.
- Return pads to their original plastic backing after each session.
- Replace pads that are dry, damaged, lifting or causing uneven stimulation.
Lead wires
If stimulation cuts in and out, switch the device off and inspect both ends of the wire. Confirm that it is fully inserted and the pad has even skin contact. Replace a wire that is kinked, cracked or producing intermittent output.
