Initial Configuration
After receiving your lantern from a Carmanah Distributor, most of the lantern’s settings should already be configured.
If you want to further customize these settings, follow the associated procedure.
SETTING
DEFINITION
PROCEDURE
Flash Code
The Flash Code controls the flash pattern the lantern
emits during operation. Select the appropriate Flash
Code from the Flash Code Table (see Appendix F)
and enter the code in this field.
Either type in the correct Flash Code, or
click the up and down arrows to select
the desired Flash Code.
Effective Intensity The Effective Intensity setting controls the lantern’s
brightness. A higher Effective Intensity setting allows
the lantern to be seen from farther away, but also
uses up more battery power and requires more solar
energy. The Effective Intensity setting is measured
in candela, and takes into account the programmed
Flash Code (using the method of Schmidt-Clausen as
per IALA E-122, Section 1.4). The Effective Intensity
value is measured in the horizontal plane.
Either type in the correct Effective
Intensity setting, or click the down arrow
and select the correct Effective Intensity
setting.
ALC (Automatic
Light Control)
When ALC is enabled, the lantern monitors the
battery pack's state of charge and reduces the
intensity level if the lantern is not receiving sufficient
solar charging to maintain the battery pack. When
the battery pack recovers, ALC automatically
resumes operation at the programmed Effective
Intensity.
If the lantern’s latitude and longitude are set
correctly, ALC reduces the Effective Intensity setting
for the lantern only under unusually poor solar
conditions.
Click the down arrow and select
On
(to
enable ALC) or
Off
(to disable ALC).
Day to Night
Transition Level
As the sun goes down in the evening, the ambient
brightness level goes down with it. The Day to Night
Transition Level (D2N) is the ambient light level
(measured in lux) at which the lantern’s beam will
turn on in the evening. A lower D2N results in the
lantern turning on later, conserving battery power.
Click the down arrow and select the
correct Day to Night Transition Level
setting.
Night to Day
Transition Level
As the sun rises, the ambient light level goes up. The
Night to Day Transition Level (N2D) is the ambient
light level (in lux) at which the lantern’s beam turns
off in the morning. A lower N2D results in the lantern
turning off earlier, conserving battery power.
NOTE
The N2D setting must be at least
25 lux greater than the D2N setting
Click the down arrow and select the
correct Night to Day Transition Level
setting.
