Notes on Use
Power supply
• The SPT-M124 must always be operated with a UL-listed 24 V AC, 60
Hz Class 2 power supply. In the U.S.A, use a power supply which is
UL listed. In Canada, use a power supply which is CSA Certified.
• The SPT-M124CE must always be operated with a 24 V AC, 50 Hz
power supply.
— When connecting the transformer, be sure to connect each lead to
the appropriate terminal. Wrong connection may cause malfunction
and/or damage to the video camera.
— Ground the unit or an irregular voltage may be generated in the AC
power cord and may cause malfunction and/or damage to the
video camera.
• The SPT-M128CE must always be operated with a 220 to 240 V AC,
50 Hz power supply.
• The SPT-M122CE must always be operated with a 12 V DC power
supply.
Handling of the unit
Be careful not to spill water or other liquids on the unit, or to get
combustible or metallic material inside the body. It used with foreign
matter inside, the camera is liable to fail, or to be a cause of fire or
electric shock.
Operating and storage locations
Avoid viewing a very bright object (such as light fittings) lor an extended
period. Avoid operating or storing the unit in the following locations.
« Extremely hot or cold places (operating temperature -10°C to +5CPC;
14^F to 122°F. however, we recommend that the unit be used within a
temperature range of -5 G C to +40 C C : 23' F to 104 F)
• Damp or dusty places
• Where it is exposed to rain
• Where it is subject to strong vibration
• Close to generators of powerful electromagnetic radiation such as
radio or TV transmitters.
Handling of the lens
As the lens could be damaged if not attached properly, make sure to
see the section “Suitable lenses' before attaching it.
Care of the unit
• Remove dust or dirt on the surface of the lens or CCD with a blower.
• Use a dry soft cloth to clean the body. If it is very dirty, use a cloth
dampened with a small quantity of neutral detergent, then wipe dry.
• Avoid the use of volatile solvents such as thinners. alcohol, benzene,
and insecticides. They may damage the surface finish and/or impair
the operation of the camera.
In the event of any problems with the operation of the camera, contact

Changing the plug on an auto iris lens cable (£
The camera is supplied with a LENS connector for inserting the power
control cable of an auto iris lens. Before connecting an auto Iris lens
however, you first have to replace the lens cable plug with the one
supplied with this camera. Replace as follows:
1 Detach the old plug from the lens cable.
2 Solder the wires to the pins of the new plug. (For cable pin assign-

Use
Power Sources — This set should be
operated only from the type of power
source indicated on the marking label. If
you are not sure of the type of electrical
power supplied to your home, consult your
dealer or local power company. For those
sets designed to operate from battery
power, or other sources, refer to the
operating instructions.
Object and Liquid Entry — Never push ob¬
jects of any kind into the set through open
ings as they may touch dangerous voltage
points or short out parts that could result
in a fire or electric shock. Never spill liquid
of any kind on the set
Grounding or Polarization This set is
equipped with a polarized ac power cord
plug (a plug having one blade wider than
the other), or with a three-wire grounding
type plug {a plug having a third pin for
grounding). Follow the instructions below :
-For the set with a polarized ac power cord
plug :
This plug will fit into the power outlet only
one way. This is a safety feature. If you are
unable to insert the plug fully into tho
outlet, try reversing the plug. If the plug
should still fail to fit, contact your electri¬
cian to have a suitable outlet installed. Do
not defeat the safety purpose of the
polarized plug by forcing it in.
-For the set with a three-wire grounding
type ac plug :
This plug will only fit into a grounding-type
power outlet. This is a safety feature. If you
are unable to insert the plug into the outlet,
contact your electrician to have a suitable
outlet installed. Do not defeat the safety
purpose of the grounding plug.
Overloading — Do not overload wall
outlets, extension cords or convenience
receptacles beyond their capacity, since
this can result in fire or electric shock.
Attachments — Do not use attachments
not recommended by the manufacturer, as
they may cause hazards.
eaning — Unplug the set from the

Ventilation — The slots and openings in
the cabinet are provided for necessary ven¬
tilation..To ensure reliable operation of the
set, and to protect it from overheating,
these slots and openings must never be
blocked or covered.
-Never cover the slots and openings with a

Antennas
Outdoor Antenna Grounding — If an outdoor antenna or cable
system is Installed, follow the precautions below.
An outdoor antenna system should not be located in the vicinity of
overnead power lines or other electric light or power circuits, or
where it can come in contact with such power lines or circuits.
WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM, EXTREME
CARE SHOULD BE TAKEN TO KEEP FROM CONTACTING SUCH
POWER LINES OR CIRCUITS AS CONTACT WITH THEM IS
ALMOST INVARIABLY FATAL.
Be sure the antenna system is grounded so as to provide some pro¬
tection against voltage surges and built-up static charges. Section
810 of the National Electrical Code provides information with
respect to proper grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit, size of
grounding conductors, location of antenna-discharge unit, connec¬
tion to grounding electrodes, and requirements for the grounding
electrode.
