3–5NM+ Solar Marine Lantern
Hibernation Mode (Advanced users) – only available for lanterns
fi
tted with GPS
For situations where the lantern is put into storage for a known period, the IR Remote control can be
used to con
fi
gure the lantern into Hibernation Mode for a user programmable date range.
Hibernation Mode maximises conservation of the battery power by disabling the light (will not activate
at night) and shutting off the GPS receiver to rely on the internal clock for date checking. The IR
sensor is still monitored in hibernation mode. Power consumption is only bettered by physically
disconnecting the battery supply.
Hibernation Mode is de
fi
ned by a start date and end date that are programmed into the lantern via the
IR Remote Control.
Using the IR Remote Control
The lantern must be in Test Mode prior to pressing any of the following key sequences. However,
the lantern will return to Normal Operation if it has not detected a valid key press for a period of 15
seconds. When the lantern exits from Test Mode it will either enter Dusk to Dawn mode, Hibernation
mode, or Storage Mode, if enabled.

The following details the key press sequence that de
fi
nes the start and end dates of Hibernation
Mode:
where
ddmm
is the numerical representation of the month (01=January, 08=August) of the start date,
and
DDMM
is the numerical representation of the end date.
e.g 9th of December is represented by the number sequence 0912.
The lantern will respond by
fl
ashing an acknowledge long
fl
ash.
This operation only stores the start & end dates into the lantern’s memory and Hibernation Mode still
must be enabled to commence its operation.
Enable Hibernation Mode
Pressing the following key sequence will enable (turn on) Hibernation Mode:
and the lantern will respond with a single
fl
ash.
The Lantern will take a new GPS reading, determine the calendar month, and then enter Hibernation
Mode and depending on the current calendar month setting will either Hibernate or enter Dusk-to-
Dawn mode.
By default, Hibernation mode is disabled. Note you can only use this command once a valid
hibernation start & end date has been stored in the lantern.
