1.0 Purpose
This Instruction Manual is intended to provide descriptive information on the Model SLX
Marine Lifejacket Light and its variations, operating instructions, information for its
maintenance and overhaul, instruction concerning the proper mounting of the light on
lifejackets to ensure compliance with minimum performance standards, and limitations for the
device.
2.0 Description of Device
The Model SLX and its variations is a SOLAS approved flashing lifejacket light that is
activated automatically when immersed in water and can be deactivated manually. Variations
of the SLX also offer manual activation or permanent deactivation. The SLX consists of a
battery and light encased in either one plastic housing (SLX), or a battery assembly and a
separate light assembly, connected by an electrical wire (SLX-II). See table 1 for options.

The battery consists of one Lithium Manganese Dioxide cell incorporated into a water-tight
sealed housing. The housing has two exposed water sensor contacts. The electronic circuit
detects water and activates the light. The design prevents inadvertent extinguishing of the
light if the water sensor is not continuously immersed in water. The housing also has a button
for the manual switching of the light.
The light is a LED covered by a polycarbonate cover.

Operating Instructions
The SLX is activated automatically following immersion of the
water sensor in fresh water or seawater. The SLX can be turned off
by pressing the button on the top of the housing. See figure 1.
•In SLX versions that allow manual activation, this can be done
by repressing the same button.
•In SLX (s) versions with permanent off, the SLX can be reset
for water activation by one long pressing of the same button.

3.0 Maintenance and Overhaul Information
1. Maintenance or periodic overhaul is not required. Overhaul at end of life is not
possible.
2. Recommended inspection of SLX:
¾Electrical Test of battery and lamp:
i. Create an electrical short between the exposed electrical contacts
using tweezers or other conductive wire, or dip the SLX in water.
a. In models with manual activation as well, one can press the
button on the top of the housing.
ii. Check that the lamp starts flashing. An inoperative light should be
rejected.
iii. Press the button on the top of the housing to switch the light off.
¾Visual Inspection:
i. Replace product if the battery housing shows obvious signs of
mechanical damage (e.g., cracking or discoloration of the plastic,
bulging of the case, etc.).
3. Defective units should be returned to the manufacturer or otherwise disposed of (see
section 5.5).
4.0 Instructions for Mounting on Lifejackets.
It is the responsibility of the lifejacket manufacturer to ensure that the light is attached
securely and is in the correct position on the lifejacket; or to provide instruction regarding
correct positioning on the lifejacket.
Recommended methods for mounting the SLX on lifejackets are as follows:
1. Attach the SLX firmly to a strap in its designated position on the lifejacket, using the
plastic clip bracket provided with the SLX. Feed the strap along the back of battery
and fasten the bracket to the battery by pushing the clip’s plastic hooks through the
corresponding holes on the battery housing. The plastic spikes should face inwards,
holding the strap firmly in place.
¾Once fastened with the clip, the light cannot be removed without breaking the
clip.
2. The SLX light should be placed at the top or on the front of the shoulder of the
lifejacket in accordance with the instructions of the lifejacket manufacturer.
3. Alternatively, one may use tie wraps or adhesive strip to attach the SLX to a strap or
fabric, making sure not to block the water sensors.
4. The light assembly of the SLX-II should be attached to the lifejacket
on the top or front of the shoulder. One may use an adhesive strip or
tie wrap, or sew the light assembly to the life jacket, attaching at any
four of the eight holes provided in the lower ring of the plastic bulb
holder. If the lifejacket has a fabric loop for the light, feed the light
assembly through the loop.
