1 Before use
1.1 Notes on the electrical system
Before connecting to a mains power supply, you must make sure that you are using
the correct input voltage. The information to select the correct mains cable is located
on the device, on the rear of the product directly above the cable entry. You must
comply with this information. If you do not comply with these specifications, then fires
or other damage to the device could occur.
The main switch must also be switched off before the mains cable is connected. In
this way you will avoid triggering an electric shock.
If you are using an extension cable, then the mains cable you use must be earthed.
If the original fuse should blow, it must only be replaced by an appropriate fuse.
When carrying out any procedures whereby you come into contact with the electrical
system of the device, such as, for example, changing the bulb or fuse, only carry out
these procedures when the power is disconnected.
Never open the housing of the illumination unit in order to change anything on the
electrics. Otherwise the guarantee expires immediately and by incorrect operations
the device might get damaged / unusable.
1.2 Storage
You should ensure that the device is not exposed to direct sunlight, temperatures
which are too high or too low, vibrations, dust or a high level of humidity.
The ideal temperature range is between 0 and 40°C and a relative humidity of 85%
should not be exceeded.
The device should always be located on a rigid, smooth, horizontal surface.

4 Operation
1. Connect the power plug to the power outlet.
2. Power on the device by pressing the main switch.
3. Bend the flexible goosenecks in order to point the LED lights in the
preferred direction.
4. Select the preferred light intensity by turning the rotary dimmer.
5 Changing the bulbs
Please contact the KERN Optics Technical Service.
6 Changing the fuse
The fuse housing is on the rear of the illumination unit next to the mains power
supply entry. With the device switched off and unplugged, you can screw out the
housing. When doing this, it is helpful to use a screwdriver or similar tool. The
defective fuse can be removed from its housing and be replaced with a new one.
After that, you just need to insert the fuse housing back into the insertion point.
