When you connect the light to the battery, the software runs a self-test, during which all five status LEDs
come on briefly. The
battery voltage
is then shown via the blue and green LEDs, as follows:
The blue LED blinks once for each volt; and then
the green LED blinks once for each 1/10 of a volt.
To see the battery voltage again, unplug the light from the battery and then plug it in again.
Guidelines in this regard:
More than 7.9 V: the battery is fully charged. 7.1 to 7.8 V: the battery
needs charging or is old. 6.5 to 7 V: the battery is not ready for use.
Note:
To deactivate this display, simply press the button. In other
words, you needn’t let the display go through its whole cycle in order
to use the lamp.
The Power Control System (PCS) measures the voltage under load.
Thus measurements using a voltmeter will not be comparable.
For example,
if the blue LED blinks seven times and the green LED
then blinks five times, this means that the measured voltage under
load is 7.5 V.
This display helps you to assess the actual level of the
battery prior to use.
Initialization; voltage display:
To activate the SOS function, hold the button down for three seconds and then release it. If you don’t
press the button again, the lamp will continue to emit the international SOS signal until the battery is
completely discharged. To deactivate the SOS function, press the button again. You can then use the
lamp in a normal fashion.
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.
To switch off the lamp,
hold the button down
for more than two seconds.
Switching the lamp off:
SOS function:
Switching on/ Changing levels:
Press the power switch once to turn the light on; two blue LEDs will glow, indicating the
22W dimming level. Press the button rapidly to cycle through other power levels. Refer
to the chart on page 40 for the exact meaning of the five (RGB) monitor LEDs, as well as
instructions for programming options additional to the factory-set 3-step mode.
The maximum lighting output can only be achieved with enough airflow to cool the
lamp. High ambient temperature and low airflow will signal the controller to reduce
power to the LEDs, thus reducing their brightness, to avoid overheating the LEDs and
other electronics. The actual reduction is indicated by the status LEDs: e.g., after a period
of low airflow conditions, 4 of the 5 blue status LEDs will be lit, indicating that the power
has been reduced from 40W to 34W in order to protect the unit from heat damage.
