Power Control System (PCS)
Three-level dimming:
This mode provides you with a third option in addition to the normal low and high beam in cases
where the low beam does not provide sufficient light. As with two-level dimming, the lower and
middle dimming levels can be individually adjusted, as follows: 4 %, 12 %, 38 % or 58 %.
Stepless dimming:
In this mode, you can adjust the light intensity steplessly from 4 % to 100 %
of maximum output.
To do this, starting at 4 % press the button until you find the desired light intensity (up to 100 %).
The blue LED comes on when the light is shining at maximum capacity. To lower the intensity,
press the button.
Note:
To avoid accidentally switching off the light while adjusting the light intensity (which can
happen for design related reasons), press the button very quickly. In other words,
avoid holding the
button down for too long,
because after two seconds the PCS will shut down the light completely.
As mentioned above, the Power Control System (PCS) monitors battery capacity via a voltage corre-
lation.
Inasmuch as battery voltage and capacity are not proportional to each other, you cannot tell
at first glance from the yellow or red LED exactly how much power is left in the battery.
However, as
you get to know your Betty light, you will be able to determine whether, for example, the yellow LED
indicates that 25 % or 50 % of battery capacity remains. The same holds true for the red LED.
Note:
To find the optimal display mode for your needs using a specific type of battery or for extreme
conditions, it is essential to try out the various modes
under real conditions, since the battery’s age as
well as the ambient temperature have an effect on the display. Thus for example if the
Middle
display
mode does not work satisfactorily, see how the PCS reacts when you switch to
High
or
Low
mode.
“High” mode
The yellow and red LEDs, as well as the reserve power function, are activated at a very early stage.
"Middle" mode
This mode – the default display program for Li-Ion batteries – normally shows capacity optimally
for this type of battery.
"Low" mode
This mode is particularly suitable for older batteries since the yellow/red LEDs and the power reserve
will be activated at a much later stage. The advantage of this mode is that an older battery with lower
voltage but adequate capacity will perform satisfactorily.
Battery warning signals:
The SOS function offers three different emergency signals, whereby the default setting is the
international SOS signal.
Note:
Use the SOS signal ONLY in an emergency. Thanks to the light’s high luminance, the signal
is visible for miles around and will continue flashing for hours if not shut off.
Improper use of the
SOS signal is punishable by law.
Power management:
Power mode
Betty 26 W
This is the default Power Control System (PCS) setting. The Betty light outputs the maximum
amount of light only when airflow lowers the temperature of the light sufficiently. If the light
is not cooled, its power is reduced incrementally to prevent the LEDs and electronic elements
from overheating.
Normal mode
Betty 24 W
Light output is slightly reduced and battery life increases accordingly. The temperature
control function is of course also activated in this mode.
Economy mode
Betty 22 W
Use this mode when you need the Betty light to be illuminated over an unusually long period.
However, in this mode the LED performance is below par. The temperature control function
remains activ in this mode.
International SOS emergency signal
Alpine emergency signal
Superflash function
This mode allows you to adjust the light’s maximum output.
SOS function:
Note:
All dimming levels indicated in these instructions are based on the maximum output
for the mode that has been set. Thus for example in Economy mode, the dimming levels are
somewhat lower, i.e. 4 % of 26 W is somewhat higher than 3 % of 22 W.
