Frequently Asked Questions
Q When 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.
Q Can I try the Obi TENS+
before going into labour?
A Yes, place 2 pads attached
to one leadwire on your
forearm to feel the different
pulse sensations following the
instructions on page 6.
Q Can I combine the Obi TENS+
with other medication?
A Yes, you can still use analgesics
such as gas and air (entinox) or
pethidine.
Q Can the Obi TENS+ be used
in hospital?
A Yes. However, a midwife
may ask you to switch it off
temporarily.

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 1 mode.
b) Begin by pressing the
CH1+ 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 small
arrow flashing on the screen.
Ensure that you increase the
intensity slowly.
c) Repeat the previous step with
the CH2+ key.You will
now feel a sensation in both
sets of pads.
d) BURST 1 (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 ‘encephalins’.
e) BOOST 1 (use during
contractions): When
experiencing a contraction,
simply press the ‘boost’ button
located on the left side below
the screen. The ObiTENS+ will
then switch automatically into
the BOOST 1 mode for that
extra surge of power required
to combat the pain during
contractions.This will feel like
a continuous sensation.
f) Once the contraction has
passed, simply press the
‘BOOST’ button.The Obi
TENS+ will return to the
original BURST 1 mode.
Continue this cycle during your
early stages of labour.
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. The pads can be used several
times. Replace the pads when
they stop sticking to the skin.
Replacement pads are available
from www.babycaretens.com.
4. 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 plug from its socket
by holding the plug between
the forefinger and thumb and
pulling gently.
5. 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.

N.B. Electrodes supplied with this
unit are all the same colour - the
black and white squares show
suggested electrode placement only.
Using the Between
ContractionTimer (BCT) timer
When in BURST mode, the unit
automatically measures your BCT.
This appears at the bottom of
the display.When you switch to
BOOST, the last BCT will remain at
the bottom of the display. The BCT
will always refresh when re-entering
the BURST mode from the BOOST
mode and will record the next BCT.
N.B.The Obi TENS+ starts up in
BURST Mode.The BCT only appears
after one cycle of pressing the Boost
Button on and off.
Recalling contraction history
To recall a list of your last 5 ‘BCTs’
press the CH1- and CH2-
buttons simultaneously. The 1st
symbol you will see is a single
moon which is the last BCT.
Use CH2+ to reveal up to 5
BCTs . Use CH2- to
review more recent BCTs. Recalling
the contraction history will not
disable functionality of the unit. To
return to the main screen press the
CH1- and CH2- buttons
simultaneously.
N.B.To avoid losing contraction
history, do NOT switch unit off.
Remove the battereis if you wish to
reset the contraction history.
The Mode Button
There are two modes available on
the Obi TENS+, each with a BURST
and BOOST function.
Mode 1 (Burst 1 and Boost 1),
which has been described above, is
primarily used for the earlier stages
of labour.
Mode 2 (Burst 2 and Boost 2) can
be used when your labour advances
and your contractions become
more frequent.
Press the Mode button to
switch between modes.You will
see from the User Display, that
the number next to the BURST or
BOOST will change from 1 to 2 and
vice-versa.
NB.Both modes are interchangeable
and can be used according to your
preference, not necessarily for the
stage of labour you are in. Mode 2
can be operated in the same way
as mode 1.

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
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.
Introduction To The Obi TENS+
The Obi TENS+ uses a state-
of-the-art, efficient method of
drug-free pain relief with no known
side effects. In order to obtain
maximum benefit, it is advised
that you seek guidance from your
medical adviser as well as reading
this instruction guide.
Precautions and
Contraindications
1. TENS must NOT be used
before the 37th week
of pregnancy.
2. If you are pregnant, do NOT
place the electrodes over your
abdomen.
3. Do NOT use if you have
a pacemaker or any other
implanted electrical device.
4. Check with your healthcare
professional before using if you
suffer from a heart condition,
epilepsy, undiagnosed pain,
have any metal implants, or
any doubts whatsoever.
5. Do NOT use if you experience
an allergic reaction to the
electrodes.
6. Never use TENS to mask
undiagnosed pain since this
could require urgent treatment.
