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.
Frequently Asked
Questions
QWhen shall I start using
my Obi TENS?
A Use as early as you can
after the onset of labour
to allow time for
your body’s pain-killing
chemicals to rise.
QCan I try the Obi TENS
before going into labour?
A Yes, place 2 pads on your
forearm to feel the
different pulse sensations
following the instructions
on page 6.
QCan I combine the Obi TENS
with other medication?
A Yes, you can still use
analgesics such as gas
and air (entinox) or
pethidine.
QCan the Obi TENS be
used in hospital?
A Yes. owever, a midwife
may ask you to switch it
off temporarily.
QCan I use the Obi TENS if
I am considering a water
birth?
A Yes, but not in the water
itself.
Troubleshooting
Questions
QWhy does the
stimulation not appear to
be as strong after you
have used the Obi TENS
for a while?
A Increase the intensity,
you may have become
used to a lower setting.
QWhy does the
stimulation feel strong
but ineffective?
A You may need to switch
off and reposition the
electrode pads.
QWhy does the
stimulation not feel
sufficiently strong even
on a high setting?
AThe batteries may need
replacing.
QWhat do I do if there is
no stimulation,
intermittent stimulation,
or weak stimulation felt
even with a new battery?
A Check electrode contact.
Check leads.
Check batteries.

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.

How Will The Obi
TENS Help Your Pain?
TENS (Transcutaneous
Electrical Nerve Stimulation)
works by passing mild
electrical impulses through
the skin, via electrode pads,
into the nerve fibres which
lie below. The TENS
impulses help your body
produce its own pain killing
chemicals, such as
‘endorphins’ and
‘encephalins’.
The level of pain relief
obtained from the Obi TENS
varies from person to
person. Some find that the
Obi TENS provides all the
pain relief required during
the whole of labour,
whereas others find that
other analgesics are also
needed during the later
stages of labour.
Precautions And
contraindications
1. Do NOT use the Obi
TENS if you have a
cardiac pacemaker.
2. Check with your medical
adviser before using if
you suffer from a heart
condition, epilepsy,
undiagnosed pain, have
any metal implants, or
any doubts whatsoever.
3. TENS must NOT be used
before the 37th week
of pregnancy.
4. Never use TENS to mask
undiagnosed pain since
this could require urgent
treatment.
5. If you are pregnant, do
NOT place the
electrodes over your
abdomen.

Additional Functions
b) Now insert the red and
white pins (at the other
end of the leadwire) into
the sockets attached to
all of the sticky
electrodes. You will see
that the lead wire is
made up of 4 wires; 2
mauve and 2 white. Do
not remove the
electrodes from the
backing at this stage (see
figure). NB. Each
leadwire has
a red and white pin at
the end. It makes NO
difference whatsoever
which electrode they are
attached to!
c) If you wish, attach the
easy-release neck cord
which enables you to
hang the Obi TENS from
your neck whilst in labour.
Insert a red and white pin
(at the end of the lead wire)
into each pair of electrodes.
The Obi TENS is an ultra simple yet powerful
obstetric TENS unit perfect for drug-free pain relief
during labour. It has 2 pre-set modes; one for use
during contractions, the other for use between
contractions.
TENS is recognised as a safe and highly effective method of pain relief
and is regularly recommended by medical professionals.
TENS is a drug free method of pain relief, with no known side effects,
which can also be used in conjunction with any additional medication
if required.
