9) Ventilation - Openings in the enclosure, if any, are provided for ventilation and to
ensure reliable operation of the unit and to protect it from overheating.These
openings must not be blocked or covered.This unit should not be placed in a built-in
installation unless proper ventilation is provided or the manufacturer’ s instructions
have been adhered to.
d) If the unit does not operate normally by following the operating instructions.
Adjust only those controls that are covered by the operating instructions, as an
improper adjustment of other controls may result in damage and will often require
extensive work by a qualified technician to restore the unit to its normal
operation.
10) Power Sources - This unit should be operated only from the type of power source
indicated on the marking label. If you are not sure of the type of power supply you
plan to use, consult your appliance dealer or local power company. For units intended
to operate from battery power, or other sources, refer to the operating instructions.
11) Grounding or Polarization - This unit may be equipped with a polarized alternating-
current line plug (a plug having one blade wider than the other).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 the outlet, try reversing the plug. If the plug should still fail to fit, contact
your electrician to replace your obsolete outlet. Do not defeat the safety purpose of
the polarized plug.Alternately, this unit may be equipped with a 3-wire grounding-type
plug, a plug having a third (grounding) pin.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 replace your obsolete outlet. Do not defeat the
safety purpose of the grounding-type plug.
12) Power-Cord Protection - Power-supply cords should be routed so that they are not
likely to be walked on or pinched by items placed upon or against them, paying
particular attention to cords and plugs, convenience receptacles, and the point where
they exit from the appliance.
13) Power Lines - An outdoor system should not be located in the vicinity of overhead
power lines or other electric light or power circuits, or where it can fall into such
power lines or circuits. When installing an outdoor system, extreme care should be
taken to keep from touching such power lines or circuits as contact with them might
be fatal. U.S.A. models only - refer to the National Electrical Code Article 820
regarding installation of CATV systems.
e) If the unit has been dropped or the cabinet has been damaged.
f) When the unit exhibits a distinct change in performance this indicates a need for
service.
18) Replacement Parts - When replacement parts are required, be sure the service
technician has used replacement parts specified by the manufacturer or have the same
characteristics as the original part. Unauthorized substitutions may result in fire,
electric shock or other hazards.
19) Safety Check - Upon completion of any service or repairs to this unit, ask the service
technician to perform safety checks to determine that the unit is in proper operating
condition.
20) Coax Grounding - If an outside cable system is connected to the unit, be sure the
cable system is grounded. U.S.A. models only—Section 810 of the National Electrical
Code,ANSI/NFPA No.70-1981, provides information with respect to proper grounding
of the mount and supporting structure, grounding of the coax to a discharge unit, size
of grounding conductors, location of discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode.
21) Lightning - For added protection of this unit during a lightning storm, or when it is left
unattended and unused for long periods of time, unplug it from the wall outlet and
disconnect the cable system.This will prevent damage to the unit due to lightning and
power-line surges.
NOTE
• For permanently connected equipment, a readily accessible disconnect device shall be
incorporated in the fixed wiring;
14) Overloading - Do not overload outlets and extension cords as this can result in a risk
of fire or electric shock.
• For pluggable equipment, the socket-outlet shall be installed near the equipment and
shall be easily accessible.
15) Object and Liquid Entry - Never push objects of any kind into this unit through
openings 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 unit.
16) Servicing - Do not attempt to service this unit yourself as opening or removing covers
may expose you to dangerous voltage or other hazards. Refer all servicing to qualified
service personnel.
17) Damage Requiring Service - Unplug the unit from the outlet and refer servicing to
qualified service personnel under the following conditions
a) When the power-supply cord or plug is damaged.
b) If liquid has been spilled, or objects have fallen into the unit.
c) If the unit has been exposed to rain or water.

The LTC 0500 series digital Black & White camera offers an extremely high level of picture
quality and resolution for use in surveillance and observation systems. It supports passive
(DC) iris, video iris and manual iris lenses.The camera is suitable for C mount and CS
mount lenses.The camera automatically detects and adapts to the type of lens fitted.
This manual describes how to install the hardware and how to use your video camera.
Check that the following items are present in the box:

Philips LTC 0500 Black & White Camera;
This manual;
Dust cap (placed onto the lens mount on delivery);
Lens connector (for connecting lenses with automatic iris control to the camera);
Low voltage connector (only for the models LTC 0500/10 and LTC 0500/20).
Three fully programmable operating modes are available to match the camera to a variety
of scene conditions. These can be selected either by using the camera push buttons or by
the RS-232 port.
An optional software configuration tool LTC0650/00 can be ordered for setting up the
operating mode functions.

5.1 LENS ADJUSTMENTS
Manual Iris Lenses
Set Lens iris to the required F. number when applicable.
Point camera at the scene.Adjust LVL (chap. 9.2.2) to desired video level.
Heavy lenses
Heavy lenses need additional support from a housing or base plate in order to withstand
vibration or shocks. Use the correct spacer height to align supported lenses in order to
prevent torque damage of internal camera components.
DC Iris Lenses
Initial lens setting
Point the camera at a test chart or scene; avoid highlights for optimum results.
Ensure sufficient scene illumination (>200 lux); the camera does not allow lens adjustment
under low light conditions.
Push LVL button once, use +/- buttons until the OSD indication on the left [DC lens level]
reaches "0".
Follow these steps to mount a lens on the camera:
1) Remove the dust cap, and screw the lens into the lens mount.
2) Where applicable, connect the iris control cable for automatic iris control to the lens
connector.
Note:
the OSD counter on the right indicates the reference value for DC lenses only.
3) You will need to adjust the back focus setting after fitting a new lens or replacing a lens.
Camera/Lens Level Adjustment
Adjust theVideo output level by pushing the LVL button again or twice if the OSD menu
has disappeared.
Use +/- buttons for adjusting desired video level (OSD indication on the right displays
video level).
NOTES:
•
Lenses without plug or with a non-compatible plug should be wired in accordance
with the drawings.
•
Lens outputs are short-circuit proof.
Video Iris Lenses
Initial lens setting
Point the camera at a test chart or scene; avoid highlights for optimum results.
Ensure sufficient scene illumination (>200 lux); the camera does not allow lens adjustment
under low light conditions.
Set the Lens ALC potmeter to the central position.
Push LVL button once, adjust the ALC potmeter until the OSD indication on the left [VI
lens Level] reaches "0".
Camera/Lens Level Adjustment
Adjust theVideo output level by pushing the LVL button again or twice if the OSD menu
has disappeared.
Use +/- buttons for adjusting desired video level (OSD indication on the right displays
video level).
