Operation

A
quick push of the button
switches between power settings.
Switching on:
Switching/low beam:
Switching off:
Pressing the button once will switch on the lamp at maximum
power. The blue LED is on.
When the lamp is connected to the battery, the software will run a self test.
The button will lash purple, red, blue and the lamp itself will lash
once.
Initialization & voltage display:
Hold the button down
(for more than one second) to switch of the lamp.
Note:
When operating the lamp at maximum power, the
power may be
reduced continuously
depending on the
ambient temperature to avoid overheating of the LEDs
and the electronics.
Lamp on
Example:
The blue LED lashes once and then the red LED lashes ive
times. This indicates that 1.5 Ah have been drawn from the battery.
Discharged battery capacity:
When you shut of the lamp, the discharged battery capacity is shown
via lashing of the blue LED and then the red LED. This information can
only be displayed once as it is deleted when you unplug the battery.
The
blue LED blinks once for each Ah (ampere hour); and then
the
red LED blinks once for each 1/10 of an Ah.
Note:
The Betty TL control electronics not only controls high and low
beam; it also protects the rechargeable battery against deep discharge
and includes a low battery indicator.
The
battery voltage
is then indicated by the blue and red LEDs, as follows:
The blue LED lashes once for each volt; and then
the red LED lashes 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.
Interpreting the voltage display:
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 control electronics measures the voltage under load.
Thus, measurements using a voltmeter will not be comparable.
Example:
The blue LED lashes seven times and the red LED then
lashes ive 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.
