Suggested 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.
Ensure unit remains switched
off. Carefully peel the pads from
the plastic backing using your
forefinger and thumb. Do not pull
on the lead wires.
2.
Position the top two pads
(connected to the left socket
CH1) 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 right socket
CH2) approximately 4cm either
side of the spine and 4-5cm
below the imaginary navel line as
seen in the diagram.

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 Obi TENS+ 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.
Using the Between Contraction
Timer (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.
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.
