Using Your Obi TENS
a) You are now ready to start
using your Obi TENS.
Switch the unit on by
pressing the on/off button.
The Obi TENS will always
start up in BURST mode.
b) Begin by pressing the
Intensity Up key. Each
time you press this key, a
small ‘half-moon’ shape
will appear on the screen
increasing in number and
size as the intensity is
increased. You will begin
to feel a pulsating
sensation which will burst
in time with the ‘half-
moon’ shape as shown on
the LCD. You will feel this
sensation in both sets
of pads.
c)
BURST (use between
contractions)
: This is the
first mode that you will
use. It feels like a bursting,
tingling sensation i.e. the
pulses are off and on
periodically. This mode
will help to promote those
all important natural pain-
killing chemicals known
as ‘endorphins’ and
‘enkephalins’.
d)
BOOST (use during
contractions)
: When
experiencing a contraction,
simply press the ‘BOOST’
key. The Obi TENS will then
switch automatically into
the BOOST mode for that
extra surge of power
required to combat the
pain during contractions.
This will feel like a
continuous sensation.
e ) Once the contraction has
passed, simply press the
‘BOOST’ key. The Obi TENS
will return to the original
BURST mode. Continue
this cycle during your early
stages of labour.

Selected Electrode
Placement Chart
The sticky electrode pads
need to be placed in the
correct position for
maximum pain relief.
It is preferable to obtain
assistance from either your
birthing partner or medical
adviser when positioning
the pads. Please read the
following instructions
carefully:
1. Carefully peel all of the
pads from the plastic
backing using your
forefinger and thumb. Do
not pull on the lead wires.
2. Position the top pads
(connected to the mauve
coloured leads)
approximately 4cm either
side of the spine and 4-
5cm above the imaginary
navel line as seen in the
diagram.
3. Position the bottom two
pads (connected to the
white coloured leads)
approximately 4cm either
side of the spine and 4-
5cm below the imaginary
navel line as seen in the
diagram. NB. It makes no
difference whatsoever
whether the mauve pads
are at the top and the
white ones are below or
vice versa, as long as they
are in horizontal pairs.

Before first use of the Obi TENS, please
familiarise yourself with the precautions and
contraindications contained on page 1 and 2.
Useful Information
1.
Continue stimulation for
as long as necessary,
unless you experience
discomfort.
2.
If you stimulate for a
number of hours ensure
the pads do not become
dry. If this occurs, switch
off the unit, disconnect
the electrodes, and apply
a small drop of water to
them.
3.
Always ensure that the
unit is switched off
before you remove all the
leads and pads. Do not
pull the wires. ALWAYS
remove the jack plugs
from their sockets by
holding the plugs
between the forefinger
and thumb.
4.
The Obi TENS can also be
used as a standard TENS
unit for relief of
numerous conditions,
including after pains and
post operative pains. It is
worth bearing this in
mind if you have a
caesarean section. Please
seek medical advice first.
