SL-75
3–5NM+ Solar Marine Lantern
Intensity/power settings on Sealite lanterns operate via DIP switches, located near the rotary switches
on the
fl
asher unit. The intensity/power settings may be used to reduce the power consumption and
intensity of the lantern. Setting the lantern to 25% intensity will reduce the power consumption to 25%
of the normal 100% setting and the range by 20% - 40% depending on the maximum intensity. Refer
to Sealite power calculator to con
fi
rm reduced range.. This setting may be used to adjust the current
draw of the light to local sunlight conditions.
The following diagrams indicate intensity/power settings:-

If the number of Full Sunlight hours is less than 2.5-3.0 hours, please consider reducing the intensity
(Power) or reducing the Duty Cycle.
All lanterns have 2 rotary switches marked A and B on the
fl
asher
unit. Turning the small arrows to the appropriate number or letter
will set the code (see
‘Flash Codes’
section, of this manual). The
unit may take up to one minute to activate a new
fl
ash code. A
comprehensive list of available
fl
ash codes is listed on pages in
the
‘Flash Codes’
section of this manual.
