NeuroTrac™ Sports Operation Manual

Neuromuscular Stimulation has been used for many years to stimulate muscle
and nerve fibres to treat a number of muscle and nerve related conditions.
Over the last 30 years numerous clinical trials and papers have been written.
The NeuroTrac™ Sports is one of a new breed of modern Neuromuscular
Stimulators which Verity Medical have developed with the Therapist and
Patient in mind. Our principle aim is to design products that have high levels of
functional use, are sensibly priced, compact and user friendly.
The NeuroTrac™ Sports is a dual channel device combining several treatment
programmes into one unit. Neuromuscular Stimulation is increasingly
understood by Therapists and Doctors. There is a better understanding of the
mechanisms which exist between nerves and muscles that makes it possible to
stimulate the neuromuscular system with precise electrical signals. The
NeuroTrac™ Sports offers precision giving full control of Pulse Widths, Rates,
Ramp up times, Work / Rest cycles as well as alternating or synchronous
application if two channels are being applied.
Customer Care
We welcome constructive comments regarding our equipment particularly those
that might help us to improve existing features, add new ones or develop new
products for the future.

1. Insert a 9 volt PP3 Alkaline battery. Alternatively insert a
rechargeable Nickel Metal Hydride battery {which has a much
longer life than the Ni-Cad rechargeable batteries} into the battery
compartment.
2. Insert lead wire/s to Channel A and B if you are using two channels.
3. Switch on the unit by pressing the on/off button on the front of the
unit.
4. Press the PRG button to select one of the pre-set programmes P01 -
P15 or PC1 - PC3 for the customised programmes (see page 8 for
customised programmes).
5. When you have selected one of the programmes, (P01 - P15, PC1 -
PC3) press the + button/s to start the programme and to increase the
mA intensity.
6. To stop the programme press the on/off button which will
turn the unit off.
Lock Button
A "concealed" Lock button is included in the NeuroTrac™ Sports which
allows the clinician to accurately monitor "Home Compliance" of the patent
between appointments. It also locks the customised or built in programmes.
To Lock the Unit
1. Select the built in or customised programme required. In the case of
a customised programme, make sure that the pulse width, frequency,
time etc. are set-up correctly.
2. Remove the battery cover and, using a thin rod gently press on the
lock button as shown in the diagram on page 6 until you hear a
double beep. The unit is now "locked" and cannot be altered until
"unlocked"
To Unlock the Unit
Remove the battery cover and press the concealed switch with a thin rod until a
single beep is heard. Now the LCD will display the average mA used on each
channel and the total hours the unit has been in use as shown in the diagram.
To return to normal "unlocked" operation, simply press the ESC button.

6. Press the SET button again and the RMP [Ramp up] symbol will flash
on/off, then press the + or - button to adjust the ramp up period from
0.1 - 9.9 seconds.
7. Press the SET button again andALT [Alternating] or SYN
[Synchronous] symbol will flash on/off, then press the + or – button to
select ALT or SYN.
8. If SYN [Synchronous] has been selected, press the SET button again to

will flash on the LCD display. Select the delay by pressing the Ch. B +/
- buttons to read the appropriate delay value (between 0.1 sec. and 4
sec)
After setting up the programme, press the ESC button to install and store the

Types Available:
* Self-Adhesive Hypoallergenic electrodes have a typical life span
(if looked after) of 4/6 weeks. We recommend cleaning the skin before
use. After use place the electrodes back onto the plastic film then
enclose them back into the ziptag plastic pouch and store in a cool
environment.
Types available:
VS.4040 40 x 40 mm (square),
VS.5050 50 x 50 mm (square) (recommended for general use),
VS.9050 90 x 50 mm (rectangular)
VS.10050 100 x 50 mm (rectangular) (recommended for large muscles),
VS.13050 130 x 50 mm (rectangular),
VS.30 30 mm Diameter (round),
VS.50 50 mm Diameter (round),
VS.62 62 mm Diameter (round),
VS.75 75mm Diameter (round).
A Few Good Tips [Self- Adhesive Electrodes]
* If you find the electrodes will not stick due to oily skin, cleanse the
skin with soap and water, then rinse and dry the area around the
electrode site. If this does not work, try cleansing the skin with a swab
impregnated with alcohol.
* Clip away hairy skin using a scissors; don’t use a razor to remove the
hairs!
The electrodes conductive material is water- based. If it becomes saturated
(e.g. from perspiration), it will lose its adhesive qualities.After use leave the
electrodes face up overnight to dry out. At some point the electrodes will
become dry. Moisten the adhesive surface with a few drops of water, and
apply onto the plastic film overnight. This procedure will give you a few more
days of electrode life.
Electrode Types & Tips

NeuroTrac™ Sports Operation Manual
18
Control Unit:
* Wipe the surface once a week with a damp cloth or antiseptic wipe
* Do not use cleaning sprays or alcohol based cleaning solutions
Battery:
* Check periodically for any discharge from the battery
* Remove battery completely from unit if not in use for any
extended period of time (typically one week)
* Low battery indicator of 6.9 volts shown on LCD display. When
flashing change battery for a new one
* Preferably use a PP3 alkaline battery
Lead Wires
* The lead wires should be handled carefully and never stretched, as
this can cause the stimulation to function below normal standards or
not at all
* Examine lead wires before each treatment for loose connections or
damage
* Avoid stretching and twisting the lead wires
* Store the lead wires carefully after each use
Self-Adhesive Electrodes
* Check the short connectors have not become separated from the
electrodes
* Replace electrodes onto plastic film after use. If they drop onto the
floor debris will adhere to conductive gel rendering the electrodes
ineffective
Caution: Static electricity may damage this product
NOTE: Only Verity Medical Ltd or appointed distributors /
importers are approved to undertake servicing.
