Obi TENS+
Quick Reference Guide
If you are in labour, please use
the quick reference guide set out
below. It is however recommended
that you read the section entitled
“Setting Up Your Obi TENS+”
found on page 5 to obtain the best
performance from your unit.
Before using the Obi
TENS+, please read the
contraindications and warnings
on pages 1 to 2.
1. Ensure the Obi TENS+ unit is
switched off.
2. Insert 2 x AAA batteries in the
compartment at the back of the
unit (see figs 1 and 2, page 6).
3. Insert the leadwire plugs into
the bottom of the unit
(see fig 3, page 6).
4. Insert the pins at the other end
of the leadwires into the sockets
attached to the electrode pads.
Do not remove the electrodes
from their backing at this stage
(see fig 4, page 6)
5. Position the electrode pads on
the body as indicated on page 7.
A pair of electrodes must be
connected to each lead wire
in order for you to feel any
sensation. The electrode pads
must be peeled away from their
backing and placed directly on
your body for you to feel any
sensation.
6. Press the (on/off) to
turn the unit on. The unit will
automatically begin operating in
burst mode.
7. Now push the (CH1 +)
key until you feel a pulsating
sensation in the first pair of
electrodes.
8. Repeat the same with the
(CH2+) key for the second pair
of electrodes.
9. At the onset of a contraction
press the ‘boost’ button for
the additional surge of power
needed to combat the pain.
10. Press the ‘boost’ button
again once the contraction has
passed and continue in the
BURST 1 mode as before.
11. See page 9 for using the
Contraction Timer.
This unit needs special precautions regarding EMC and needs
to be installed and put into service according to the EMC
information provided in the ACCOMPANYING DOCUMENT.

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.
Setting Up Your Obi TENS+
Check the following contents:
•
1 x Obi TENS+ unit
•
1 x Pack of 4 self adhesive
electrodes (40mm x 100mm)
•
2 x Leadwires
•
2 x AAA batteries
•
1 x Carrying pouch
•
1 x Easy-release neck cord
•
1 x Instruction manual
•
1 x EMC documentation
The Assembly Stage
a)
Remove the cover to reveal the
battery compartment (see fig
1, page 6).
b)
Insert 2 x AAA batteries (see
fig 2, page 6), ensuring the
positive (+) and negative
(-) terminals are correctly
positioned as marked in the
battery compartment. Replace
the cover. Ensure the unit is
switched off.
c)
Take the two white leadwires
and insert each of the black
jack plugs (at one end of each
leadwire) into the sockets at
the bottom of the Obi TENS+
unit (see fig 3, page 6).
d)
Now insert the pins (at the
other end of the leadwires) into
the sockets attached to the
sticky electrodes. Each leadwire
has two pins, ensure each pin
is attached to an electrode. Do
not remove the electrodes from
the backing at this stage (see
fig 4, page 6).
NB. Each leadwire has a
red and black pin. It makes
NO difference whatsoever
which electrode they are
attached to!
e)
If you wish, attach the
easy-release neck cord which
enables you to hang the Obi
TENS+ from your neck whilst
in labour (see fig 5, page 6).
Now position your electrodes
(see page 7
Display Symbols
And Their Meanings

You can switch between them by
pressing the Mode key.
: This function is
used at the onset of labour and
in-between contractions. There
are two Burst modes available
indicated by a 1 or 2 next to the
word BURST.
You can switch between them by
pressing the Mode Key.
Low Battery Indicator: This
sign will start flashing if the bat-
teries are running low. If this is the
case, change both batteries. Please
refer to page 5 for instructions.
Between Contraction
Timer: This automatically measures
the time interval between your
contractions.
Pad contact warning (safety
cut-out): This symbol will appear if
any of your pads are not attached
securely to the skin.
General Precautions
1. Do NOT use this unit without
first reading these instructions.
2. Do NOT immerse the Obi
TENS+ in any liquid. Do not
use in the bath or the shower
3. Do NOT place it close to any
source of excessive heat or
operate it in the presence of
flammable gas.
4. Do NOT drop this unit onto
a hard surface.
5. Do NOT attempt to dismantle
the Obi TENS+.
6. Only use specified batteries
and electrodes.
7. If damaged, do not use.
Return to supplier.
8. Remove the batteries when
not in use.
9. Do NOT use while driving or
operating potentially dangerous
machinery or while using
a microwave.
10. Keep out of the reach
of children.
11. Do NOT place electrodes on
or near the eyes, in the mouth,
over the front or sides of the
neck or across the head or
the heart.
12. Do NOT place the electrodes
on varicose veins or recent
scarring or on any area of
broken, inflamed, infected
or numb skin. Electrodes
should generally only be
applied to skin with normal
sensation unless under medical
supervision.
13. Do NOT use in the presence
of tuberculosis, malignant
tumours, very high or very
low blood pressure, high
fever or acute inflammatory
disease unless under medical
supervision.
14. A mild shock may be caused if
one electrode is accidentally
removed. In the event of this
happening the unit should be
turned off immediately.
SN
