• Ensure that the watch is positioned sideways in order
to prevent scratches on the glass.
With screen insert
• Smaller items in particular can be moved around by
the ultrasonic excitation and thus become scratched.
• Use the screen insert. Doing so will prevent potential
vibrations.
• Using the screen insert reduces the cleaning power.
Cleaning larger items
You can also use the unit to clean larger items.
• Always place the item partially into the container.
• Do not touch or hold the item during cleaning.
• For larger items, ensure that the unit is secured against
tipping.
Intensive cleaning
For intensive cleaning, for example of heavily soiled
items, repeat the cleaning process several times, but
no more than three times in a row.
Allow the unit to cool down for approx. 5 minutes before
using it again.
Notes
• In this case, replace the cleaning fluid before each
additional cleaning process.
As a precaution, enquire in the store where you have
purchased the item whether it is suitable for cleaning
using the unit.
Caution!
Do not use the unit for cleaning sensitive or porous
stones as listed below since they may become dam-
aged due to their structure:
• Pearl and nacre,
• Emerald,
• Opal,
• Coral,
• Turquoise,
• Lapis lazuli,
• Malachite,
• Black onyx,
• Tiger's eye.
We accept no liability for any damage that may be sus-
tained when using the device!
6. Operation
Notes
• Only use cold or lukewarm water.
• The cleaning results can be improved by adding a
small amount of mild dish soap or a cleaning solution
for ultrasonic units.
• You will achieve the best cleaning power by placing the
item in the centre of the unit and adding just as much
water as needed to fully immerse the item in water.
• Do not use flammable cleaning fluids (denatured alco-
hol, petroleum ether or isopropanol). Explosion hazard!
• Do not use soaps with a strong moisturising effect.
• The device must only be connected to the power sup-
ply once it has been fully loaded and all preparatory
work has been completed!
