A 6.3 Setting the lamp voltage
The lamp voltage can be changed in the
range from 3.0 V to 3.8 V (measured at the
housing plug) with the motor switched off.
The voltage at the lamp itself is 500 mV
below the set value.
The factory setting on delivery is 3.2 V
(about 2.7 V at the lamp).
Call up the “Lamp voltage setting“
subroutine by pressing the keys 4
REVERSE and 1 ↑ together. The display
3 shows the value last saved (in volt).
This value last saved can be changed
continuously between 3.0 V and 3.8 V by
pressing the keys 1 ↑ and 2 ↓.
The setting is completed by pressing key
4 REVERSE for a long time, and the
setting is saved.
There is an automatic switch-off for the
light after 2 seconds.
