Switching off:
The first press of the button switches on the light with
maximum power. The blue LED is illuminated.

Note:
The Piko control electronics not only controls high and
low beam; it also protects the rechargeable battery against deep
discharge and includes a low battery indicator.
Battery voltage
(once per Volt)
Battery voltage
(once per 1/10 Volt)
To switch off the lamp,
keep the button pressed
for more than
two seconds.
Note:
The light outputs the maximum amount of light only if
airflow lowers the temperature of the light sufficiently. If the
light is not cooled by airflow, its power is reduced
incrementally
to prevent the LEDs and electronic elements from overheating.
Lamp on
After connecting the lamp to the battery, the software runs a selftest; the
lamp itself as well as the red and blue LEDs in the switch light up once
The
battery voltage
is then indicated by the blue and red LEDs, as follows:
The blue LED flashes once for each volt; and then
the red LED flashes once for each 1/10 of a volt.
To display the battery voltage again, unplug the light from the battery
and then plug it in again.
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 control electronics measures the voltage under load.
Thus, measurements using a voltmeter will not be comparable.
Example:
The blue LED flashes seven times and the red LED then
flashes five times; this means that the measured voltage under load
is 7.5 V.
This display helps you assess the actual state of the battery
prior to use.
Initialization & voltage display:
battery is fully charged:
more than 7.9 V
battery needs charging or is old:
7.1 to 7.8 V
battery is not ready for use:
6.5 to 7 V
