Operating Manual
for Dermalux® Checkbox Multimedia (mains version)
Dear customer,
here are some application references which you should pay attention to while operating the
Dermalux® Checkbox.
Using the Dermalux® Checkbox (mains version) for the first time
Never switch on the unit without fluorescent tubes. To operate the unit on the mains, insert the
power supply plug (230 V/12V) into the mains socket. Then insert the 12V-plug
into the socket located on the rear of the unit next to the switch. To ensure that the plug is fitted
correctly, use gentle pressure to continue pushing it through the small level of resistance. After
actuating the switch, the Dermalux® Checkbox is operational once the indicator lamp located on
the unit lights up.
Operation as a battery version
Never switch on the unit without fluorescent tubes. If you have bought the battery version of the
Dermalux® Checkbox, the battery pack will already be in the relevant battery compartment on the
rear of the unit. First proceed as for the mains version. For battery operation, however, the unit
must be connected to the mains for at least 12 hours before being used for the first time. The unit
must not be switched on during this period. It is also possible to operate the unit from the mains
straight away. Please ensure that the battery is maintained. It should not remain unused for
longer than 4-6 weeks.
Recharging the battery
Connect the power pack to the mains socket for at least 8 hours. The electronic charging system
will take care of everything else, including preventing an overcharge. After this period, your
Dermalux® Checkbox will be ready for operation for another 3 hours approx. when disconnected
from the mains.
Maintenance/cleaning of the unit
Please do not use any solvent-based cleaning agents to remove Dermalux® test product residue
from the surface of the box.
Lamps
The unit is fitted with two fluorescent lamps of type T5 8W/BLB and must only be operated with
this type of lamp. These lamps are black light lamps with a general missions range of 320 nm ̧
400 nm (UV-A), max. 365 nm. Eff. illumination intensity UV-A (0.5m) ̃ 1.2 W/m²
