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.

◼The high luminance of the LED can cause severe damage to the eye if viewed directly. ALWAYS wear

suitable protective goggles when viewing the LED.

◼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 LED has cooled sufficiently before removal.

◼Due to the vast range of LED modules available it may appear possible that more powerful LED’s can

be used in the equipment than for which it was designed. Even when the unit will physically accept a

higher wattage LED, this substitution is not recommended and is dangerous. This action will also void

any warranties on the equipment.

procedures should be adhered to in order to ensure a safe working environment and reduce the risk of

damage or personal injury.

Preparing the Mounting Position

Mark out and drill the fixing holes through the deck, using the template provided. If anti-vibration mounts

are to be fitted, the fixing holes for the mounts should also be marked out and drilled. Prior to manoeuvring

the searchlight into its’ fixing position, the AV mounts should be fitted to the base.

In the case of cabin control models, a centre hole is also required to allow the mechanism to pass through.

Fit the ‘O’ ring in position and bolt the searchlight down securely. On an uneven surface it is necessary to

use a suitable sealant, such as silicone, to ensure a weatherproofed joint.

underside of the searchlight, the desired beam can be achieved for any particular application. The beam

will move through ‘spot’ to ‘flood’. In order to fix the beam type; simply release the knob at the desired

position

Using the template provided mark out and drill the fixing holes through the deck or cabin roof. In case of

cabin control models, a centre hole is also required to allow the mechanism to pass through.

On an uneven surface when bolting down the searchlight it is necessary to use a suitable sealant, such as

silicone, in order to ensure weather proofed joint.
