Setting the Night to Day Transition Level
The Night to Day Transition Level (N2D) is the
ambient brightness at which the lantern comes on in
the morning (measured in Lux). A higher value for the
N2D Transition Level causes the lantern to turn on
later in the morning; a lower value makes it turn on
earlier.
NOTE
You cannot program the N2D
Transition Level to be lesser value
than the D2N Transition Level.
To set the N2D Transition Level:
1. Remove the lantern’s Bottom Cover and plug the
USB cable into the USB port.
2. Connect the other end of the USB cable to an
empty USB port on your computer.
3. Open 650DM on your computer. 650DM may take
a moment to find and connect to the lantern.
4. Click
Configuration
on the Bottom Bar. The
Configuration
screen appears.
5. In the
Device Function
area, click the
down arrow
beside the
Night to Day Transition
field, and select
the appropriate value. The
Setting
column values
for Autonomy and the Effective Intensity Limit (in
the
Derived Values
area), change to reflect the
effect of the new N2D Transition Level. [
6. Click
Send Setting to Device
. The new N2D
Transition value is sent to the lantern. The values
for Autonomy and the Effective Intensity Limit,
in the
Device
column of the
Derived Values
area, change to reflect the effect of the new N2D
Transition Level.
Setting the ALC
When ALC (Automatic Light Control) is enabled, the
lantern monitors the battery pack's state of charge
and reduces the Effective Intensity level if the lantern
is not receiving sufficient solar charging to maintain
the battery pack's state of charge.
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.
To turn ALC off:
1. Remove the lantern’s Bottom Cover and plug the
USB cable into the USB port.
2. Connect the other end of the USB cable to an
empty USB port on your computer.
3. Open 650DM on your computer. 650DM may take
a moment to find and connect to the lantern.
4. Click
Configuration
on the Bottom Bar. The
Configuration
screen appears.
5. In the
Device Function
area, click the
down arrow
beside the
ALC
field, and select
Off
to disable
ALC, or select
On
to enable ALC.
6. Click
Send Settings to Device
. Your setting
change is sent to the lantern.
