KL 1600 LED – Operating instructions
7/10
2.4 Light intensity setting
The brightness can be adjusted continuously by turning the
light intensity setting knob (1).
Six-step intensity control is possible, from 0 – 5.
The highest brightness is reached at the end stop at
position 5.
When the brightness control is set at 0 there is no more
brightness, i.e. the lamp is off.
Attention:
Please note that when the brightness control is
set at 0 the instrument is not switched off. When the
instrument is switched on the green control light (11) is lit. To
switch off the KL 1600 LED by pressing the on/off switch (2)
once (see point 2.3 “Start-up procedure”). Please ensure
safe power disconnection by pulling out the power plug!
2.5 Filter slide
The KL 1600 LED has a filter slide (8) which can be fitted with an insert filter from the filter set
(available as accessory).
When operating the light source the filter slide must always be engaged in one of the end positions
or in the rest position. This is the only way to guarantee optimum air cooling of the light source.
Operating the light source with the filter slide in an intermediate position can cause damage to the
slide.
Fitting the filter slide
Please ensure the filter slide (8) has cooled down before fitting the insert filter.
Completely pull out the filter slide (8) from the light source and slot the required filter from the filter
set into the provided holder, ensuring the filter is lying flat in the holder.
Push the filter slide as far as the stop to ensure the filter is positioned in the optical light path.
If you wish to operate the light source for a short time without a filter then only pull the slide out to
the first rest position. In this position the filter is still in the light source, but no longer in the light path.
