Cleaning the charging station plug-connectors
This is how you clean the plug-connectors of a charging station:
(1)
Separate the DC power supply cable from the charging station.
(2)
Dip the end of a cotton bud in Isopropyl.
(3)
Rub over the contacts of the plug-connector(s) with the tip of the cotton bud. Move
the cotton bud slowly from one side of the plug-connector to the other and back
again. Pay attention that that no cotton residue remains on the plug-connectors.
(4)
All of the plug-connector sides should also be cleaned with the help of the cotton
bud.
(5)
Spray compressed air onto the plug-connector area and keep the hose, resp. the
nozzle about 15 mm above the surface.
Attention!
Do not direct the nozzle onto yourself or other persons. Pay attention that the nozzle
does not point towards your face.
(6)
Make sure that no lint remains from the cotton buds and remove any lint.
(7)
If there are any grease and dirt deposits on other sectors of the charging station,
remove this with a lint-free cloth and alcohol.
(8)
Allow the alcohol to dry at least 10 to 30 minutes in the air (depending on the
ambient temperature and humidity) before you connect the charging station to the
power source. The required drying time increases with lower temperature and high
humidity. The required drying time decreases with higher temperature and lower
humidity.

Cleaning interval
The cleaning frequency is up to the customer’s discretion due to the varied environments
in which the mobile devices are used. They may be cleaned as frequently as required.
However when used in dirty environments it may be advisable to periodically clean the
scanner exit window to ensure optimum scanning performance.
