FIRST AID IN CASE OF ELECTRIC SHOCK
1.
SWITCH OFF.
If this is not possible, PROTECT
YOURSELF with dry insulating material and pull
the victim clear of the conductor. DO NOT
TOUCH THE VICTIM WITH YOUR BARE HANDS
until he is clear of the conductor, but DO NOT
WASTE TIME.
2.
(a) Place the victim in the sup
ine position.
(b) Keep the air passages clear by turning the
head to one side, opening the patient's mouth
and clearing it of water, saline, mucus or
blood, a lot of which might have accumulated
in the back of the throat. (Figure 1)
3.
4.
If the j
aw is rigid try to force the mouth open
by pressure on the gum behind the last molar
tooth of the lower jaw. When the upper air
passages are thus cleared, tilt the head
backward and force the jaw forwards from
the angles of the jaw in front of the ears. This
would prevent mechanical obstructions to the
upper air passages. (Figure 2-3)
(a) Then hold the chin up and forward with
one hand and pinch the nostrils of the victim
with the other. (Figure 4)
(b) Take a very deep breath and apply your
mouth to that of the victim and blow into his
mouth, until the chest of the victim moves up
indicating filling of the lungs. (NEVER ALLOW
THE CHIN TO SAG). (Figure 4)

5.
When the chest has moved up, withdraw your
mouth and allow the chest to slink back.
REPEAT this process every three to four
seconds until the victim begins to breathe
again or until he is taken over by a medical
attendant. This method can be continued in an
ambulance during transit of the patient from
the site of accident to the nearest medical
centre.
HAVE SOMEONE ELSE AND SEND FOR A DOCTOR.
KEEP PATIENT WARM AND LOOSEN HIS CLOTHING.
DO NOT GIVE LIQUIDS UNTIL THE PATIENT IS CONSCIOUS.
WARNING
DO NOT REMOVE THE FRONT PANEL & TRY TO REPAIR
THE EQUIPMENT BY ANY UNAUTHORISED PERSON SINCE
LCD IS VERY SENSITIVE PART OF THE EQUIPMENT
WARRANTY WIL BE VOID INCASE OF ANY MAJOR
DAMGE TO THE EQUIPMENT

Congratulations on being a proud holder of INDIA’s 1st & Fully Indigenous OTDR.
We are very proud of our efforts but will always look at user feedback to better
it. Kindly do send your feedback to andigsystem@gmail.com
WARNINGS & CAUTIONS
WARNING! Do not connect the OTDR to any fiber that is not dark, or that is
terminated by a device with reflectivity > -13 dB.
Please be aware of any APC connector used in the network. APC connectors are
mainly used in long haul & do not produce any reflections that are seen on the
OTDR Screen. APC Connectors are designed to deflect the Fresnel by 7⁰ causing
it to look as a non-reflective splice.
CAUTION!
To avoid serious eye injury, never look directly into the optical outputs of fiber
optic network equipment, test equipment, patch cords, or test jumpers. Refer to
your company’s safety procedures when working with optical systems.
WARNING!
Use only the specified AC adapter. Use of another type of AC adapter can
damage the instrument and create the danger of fire and electrical shock.
WARNING!
To avoid the danger of fire and electrical shock:
Never use a voltage that is different from that for which the AC adapter
is rated.
Do not plug the unit into a power outlet that is shared by other devices.
Never modify the power cord or excessively bend, twist, or pull it.
Do not allow the power cord to become damaged. Do not place heavy
objects on the power cord or expose it to heat.
Never touch the AC adapter while your hands are wet.
Should the power cord become seriously damaged (internal wiring
exposed or shorted), contact the manufacturer to request servicing.
