The safety of TENS devices for use during pregnancy or birth has not been
established.
·
This device is not effective for pain of central origin. (This includes headache.)
·
This device should only be used under the continued supervision of a physician.
·
This device does not have curative value.
· This device offers symptomatic treatment such as suppressing the sensation of
pain which would otherwise serve as a protective mechanism.
·
The user must keep this device out of the reach of children.
· Electronic monitoring equipment (such as ECG monitors and ECG alarms) may not
operate properly when this device is in use.
·
The long - term effects of chronic electrical stimulation are unknown.
· Stimulation should not be applied over the carotid sinus nerves, particularly in
patients with known sensitivity to the carotid sinus reflex.
·
Stimulation should not be applied over the neck or mouth. Severe spasm of the
laryngeal and pharyngeal muscles may occur and the contractions may be strong
enough to close the airway or cause difficulty in breathing.

Preprogrammed Modes
Interferential Current (IFC)
Mode Description
Low - High The frequency of channel 2 sweeps between 4001 Hz and 4128
Hz every 15 seconds, while the channel 1 frequency remains
fixed at 4000 Hz.
Low The frequency of channel 2 sweeps between 4001 Hz and 4010
Hz every 15 seconds, while the channel 1 frequency remains
fixed at 4000 Hz.
Combo Combo consists of three 2 minute cycles which repeat over the
duration of the treatment.
1st cycle - Low Mode: as described above.
2nd cycle - High Mode: like Low Mode, but channel 2 sweeps
between 4064 Hz and 4128 Hz.
3rd cycle - Muscle Mode: The frequency of channel 2 is fixed at
4064 Hz, and the frequency of channel 1 is fixed at 4000 Hz.
Both channels are cycled on and off simultaneously at 6 second
intervals.
Transcutaneous Electrical Nerve Stimulation (TENS)
Mode Description
Sweep The frequency is decreased linearly from 125 Hz to 11 Hz over a
4 second span. During this time, the pulse width is increased
linearly from 120 µs to 300 µs. Then the frequency is decreased
from 10 Hz to 1 Hz over a two second span. The pulse width is
constant at 300 µs. Then the frequency is increased linearly
from 1 Hz to 10 Hz over a two second span. The pulse width is
constant at 300 µs. Then the frequency is increased linearly
from 11 Hz to 125 Hz over a four second span. During this time,
the pulse width is decreased linearly from 300 µs to 120 µs.
Low frequency
Modulation Frequency sweeps between 66.7 - 100 Hz and back again over
12 seconds. Pulse width linearly decreases to 150 µs when
frequency is sweeping up and increases back up to the default
pulse width of 300 µs when frequency is sweeping down.
High frequency
Modulation Same as Lmd, but with a frequency shift interval of 2 seconds.
