2 - Safety Precautions
The following instructions must be adhered to, in order to ensure a safe working environment
and the safety of the user.
Note: When unpacking or manoeuvring the searchlight into its fixing position, suitable
lifting points must be used in order to prevent damage to the equipment or personal
injury.
Prevent rain, snow, condensation and water droplets from contacting the lamp as this may
cause bulb failure and possible shattering;
Quartz halogen bulbs run with a high internal pressure in excess of atmospheric. Whilst the
construction is inherently strong, there is a slight risk of the bulb shattering;
Never look directly into an illuminated searchlight as this may cause severe damage to
eyesight. If it is necessary to inspect a lamp whilst in operation, always wear suitable
protective goggles;
Should it be necessary to examine the lamp with the front bezel removed, always use a
protective shield and wear goggles to ensure a safe working environment;
Never attempt to clean a lamp whilst in use;
Searchlights get hot. Never touch the unit when lit and always allow 15 to 20 minutes for
cooling down after turning the searchlight off;
Never place anything on or cover the searchlight when in use;
Ensure the lamp has cooled sufficiently before removal;
If undue force appears necessary to remove the lamp, the equipment should be inspected
by a competent person or contact the manufacturer;
When breaking a lamp for disposal, care must be taken to ensure the glass fragments are
safely contained. This operation must be performed out of doors in free air. In all
circumstances refer to the lamp manufacturers instructions packed with the lamp;
Due to the vast range of lamps available it may appear possible that more powerful lamps
can be used in the equipment than for which it was designed. Even when the unit will
physically accept a higher wattage or voltage lamp, this substitution is not recommended
and is dangerous. This action will also void any warranties on the equipment.
Always refer to the lamp manufacturer’s technical data when dealing with lamps.

5 - Electrical Installation
Note: ~
When the main power is first applied to the searchlight, the searchlight will carry out a
self-test, it will Pan to the left limit and Tilt down to the limit, once this is complete, the
searchlight will then move to the centre and horizontal, during this please do not try and
operate the searchlight while this test is being carried out. Once the searchlight is back
at centre the searchlight can then be operated normally, by pressing the Panel button on
the control panel.
For safety purposes, only competent personnel should perform the electrical installation. All
equipment should be installed to current Electrical Regulations and Standards.
In order to obtain the maximum light output from the searchlight, it is essential that the full
operating voltage of the lamp fitted be applied to the lampholder contacts.
Method of Electrical Connection
1) Disconnect the supply before working on the electrical system;
2) The searchlight must be connected to a fused electrical supply, using suitably sized cable;
3) If the searchlight is located a considerable distance from the supply, provision must be
made in the cable size in order to overcome the voltage drop.
The following table below indicates the maximum length of cable to be used for the supply
cable, from the junction box to the searchlight:

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. (See Fig 1 below for aid to instructions)
To operate the panel, press panel button (1), the button will light up & the joystick (4) is now
operational. To switch the lamp on or off press the lamp button (2)
The speed of movement depends on the more pressure applied to the joystick (4) the faster the
searchlight moves. When in the desired position the joystick should be released so that it
returns to dead centre.
On remote focus models the beam of the searchlight can be adjusted to give a variety of beam
types. Using the focus button (3) 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 focus button at the desired position.
To return the searchlight to Factory set auto home position (forward and horizontal) simply
switch off the joystick panel using the panel button (1) and then press the lamp button (2), the
searchlight will then move to the pre-programed home position.
To set a new Home position, move the searchlight to the desired home position, switch off the
panel (1), move the joystick to the downward position ↓ and simultaneously press the Lamp
button (2).
There is the option for added slave panels, the slave panel has all the features of the main
control panel i.e. joystick, focus and on/off.
When the lamp is switched on, this will illuminate the Lamp button (1) on both the Main & Slave
Control panel, also when the Focus button (3) is pressed, both Focus buttons will be
illuminated.
The brightness of the panel can be increased or decreased by holding the panel switch (1)
down and moving the joystick left and right, left to decrease right to increase.

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 manufacturer’s data should be referred to when dealing
with lamps.
