6 - Operating Instructions
This equipment is designed for use out of doors, in free air. Never place anything on, or cover the
searchlight when in use as this may present a hazard.
The searchlight can be remotely positioned via the joystick control panel, with the facility for
movement up, down, left and right. When in the desired position the joystick should be released so
that it returns to its’ home position, dead centre.
The beam of the searchlight can be adjusted to give a variety of beam types. Using the yellow
remote focus button on the joystick panel, the desired beam can be achieved for any particular
application. The beam will move continuously through ‘spot’ to ‘flood’. In order to fix the beam type;
simply release the button at the desired position.
The heaters specified on this equipment are self-regulating and will shut off when they reach the
dew point temperature.
This product should not be used for any purpose other than for which it was designed. Any
modifications to the product should not be undertaken without consulting the manufacturer.
Setting to Work
Safe service in use necessitates the strict observance of the following precautions.
Any article fabricated from quartz or glass is inherently fragile and care should
therefore be taken, at all times, when handling lamps;
Eye protection must be worn when handling lamps that have been removed from their
packaging materials. The protective jacket should not be removed from the lamp for
safety reasons, as there is a remote possibility of the lamp shattering violently,
especially if it is subjected to mechanical shock or vibration;
Always isolate the equipment from the supply before inserting a lamp;
Before inserting the lamp ensure that all contacts are clean. Contacts must be
renewed at the slightest sign of corrosion. Sanding or filing down corroded areas is not
recommended as this will only make the conducting surface between the pin and
lampholder smaller, thus causing the lamp to overheat;
Do not twist or bend the fused quartz bulb when fitting the lamp as mechanical
stresses MUST be avoided;
The lamp must be capable of unimpeded expansion when it warms up to operating
temperature. Mechanical forces must not be applied to the fused quartz bulb;
Before the protective jacket is removed, suitable protection must be worn i.e face mask
and gloves with wrist protection;
Never touch the quartz bulb with bare hands, as fingerprints will make the glass cloudy
and cause a severe loss of light. This may also cause recrystallisation and thus
weaken the bulb material. Should the bulb be inadvertently touched, remove
fingerprints with methylated spirit and a clean, soft paper towel. The bulb should then
be wiped with distilled water. NOTE: ALWAYS WEAR MASK AND GLOVES DURING
CLEANING);
In all circumstances the lamp manufacturers data should be referred to when dealing with
lamps.
